The construction process of glass melting furnace is generally to first lay the bottom flue and heat storage chamber, and then lay the bottom, wall and breast wall bricks of the large kiln.
If you want to learn more, please visit our website.
When laying the top layer of bricks at the bottom of the flue, it should be perpendicular to the airflow direction, and the masonry should be started from the middle of the flue and carried out at both ends. When laying the flue, an expansion line of about 10mm is left for every 3m of straight line length, and it is staggered up and down, inside and outside. The masonry around the air exchanger should be inlaid after the gate frame is installed and inspected and qualified.

1) The outer wall of the heat storage chamber requires staggered laying of bricks of different types, and no straight joints of clay bricks (insulation bricks) and red bricks are allowed between two adjacent rows horizontally. One row is laid every 4 to 5 rows. The outer surface of the wall should be close to the I-beam column.
2) The partition wall of the heat storage chamber should be laid with staggered joints. Expansion joints are left at the door stacks of the heat storage chamber at both ends of the partition wall. Clay slurry is used for the clay brick part and silica slurry is used for the silica brick part. Mixing is strictly prohibited.
3) The heat storage chamber grate bars are not allowed to be skewed, and their spacing should be strictly kept accurate. The grate bar climbing (surface leveling) requires strict leveling.
When laying the heat storage chamber grate bars, first set the arch tire and then use the grate bar card plate to measure. Only after it meets the card plate can the grate be laid. The center line of the grate bar arch foot surface should be on the same straight line.
4) When building the door arch of each small furnace and heat storage chamber, first support the arch tire and then use the furnace bar to check the quantity. Only when it meets the card plate can it be built, and the semi-circular arch bricks between the arch foot bricks are built, and then the door arch is built. The door arch lock brick is 30mm higher than the arch top, and grouting should be carried out after it is driven in.
5) The error between the actual center line and the designed center line of each small furnace and heat storage chamber should not exceed 5mm.
6) Before building the semi-circular arch, the semi-circular arch should be tested horizontally and vertically to check whether it is qualified to determine the size of the mud joint.
When building the arch, use the mortar brushing operation. After each brick is placed, it must be knocked tight with a wooden hammer to make it tightly combined. After each row of bricklaying is completed, it must be leveled with a horizontal plate. When building the arch, both sides should be built at the same time to prevent the arch tire from moving. The joints between the semi-circular arch and the door arch or the small furnace weighing horizontal arch should be processed in advance, pre-built and numbered, and built according to the numbers when building. The lock bricks of the semicircular arch should be 50~80mm higher than the arch top. The lock bricks on the arches must be at the same angle and hammered in at the same time, and then grouting is carried out.
7) The weighing horizontal arch of the small furnace should be built in a circle, and its lock bricks should be 50mm higher than the arch top, hammered in together with a wooden hammer, and then grouting is carried out. The small furnace can be built after the column tie rods of the heat storage chamber are tightened and the arch bricks leave the arch tire.
8) The stacking of lattice bricks requires vertical and horizontal, the error of the center line of each grid hole shall not exceed 5mm, the error of the grid hole size shall not exceed 6mm, and the horizontal error of the upper surface of the lattice brick shall not exceed 8mm. When leveling the lattice bricks, it is strictly forbidden to use asbestos and other materials to solve the problem.
9) The holes for blowing in the heat storage chamber sealing wall must be left facing each longitudinal grid hole and closed with a race brick.
10) When laying the heat storage chamber wall, clay bricks must be laid between the grate arch foot, the semicircular arch and the outer wall reinforcement iron parts.

1) The center lines of the small furnace ascending path should be laid out according to the design standards, and the error should not exceed 5mm. The center lines of each pair of small furnaces should overlap with each other, and the error should not exceed 10mm. The center line of the small path should be strictly perpendicular to the center line of the kiln pool.
2) The cross-sectional dimensions must be accurate during masonry, and the four corners of the small furnace must be neat to facilitate the installation of the steel structure.
3) A 30mm expansion joint is left between the bottom of the small furnace neck and the front wall of the small furnace. Straw ropes are used to pad the joints during masonry, and then pulled out after masonry is completed.
4) The small furnace arch is always built with mortar.
5) When laying the small furnace arch and locking bricks, the arch foot angles on both sides should be fixed.
1) Large clay bricks at the bottom of the melting furnace pool are required to be dry-stacked. They must be selected, processed and numbered in advance. Bricks that make a mute or cracking sound when knocked, have cracks or caves, and have a break of about 30mm on the outside and more than 10mm on the inside are not allowed to be used.
2) Except for the surface that contacts the glass liquid, the remaining surfaces of large clay bricks at the bottom of the melting furnace pool should be processed. The processed surface of the brick should be checked with a ruler and a square ruler. The gap between the ruler and the brick surface should not exceed 1mm.
3) The bottom of each part of the masonry should be stacked from the center line to both sides. The brick joints must be staggered with the flat steel at the bottom of the kiln. The bottom of the kiln should be stacked directly, horizontally and vertically parallel. Expansion joints should be left between bricks. The upper part of the gap should be clamped with horse manure paper of about 50mm to prevent broken bricks and glass from entering.
4) The pool bottom bricks must be leveled, especially the upper surface of the pool bottom where the pool wall is built must be measured and leveled to ensure that the entire kiln is strictly level.

1) The electro-melting cast bricks for the pool wall should be weighed piece by piece, and the bricks with large volume should be used in the high-temperature and easily corroded parts of the melting part and the feeding pool, and the corners of the entrance of the neck.
2) The corners of the pool wall should be stacked into straight seams, and it is strictly forbidden to bite the slag. The straight seams should be parallel to the longer section of the pool wall.
3) The pool wall must be straight, and the casting mouth of the mullite or zirconium corundum bricks should face the pool. The brick joints must be tight, staggered up and down, and there must be no through seams, and the gap must not exceed 5mm.
4) The allowable error of the top surface elevation of the entire melting furnace pool wall does not need to exceed ±10mm. At the same time, the top surface elevation of the melting part pool wall should not be lower than the standard of the top surface of the pool wall in front of the liquid outlet.
5) After the pool wall, the pool bottom and its upper structure that are in contact with the glass liquid are all built, the inner surface of the masonry should be cleaned of dirt with a steel brush and blown clean with compressed air.
1) When laying hook bricks and breast wall, measures should be taken to prevent them from tipping into the kiln. When placing hook bricks, pull a line through the cast iron plate to level and spread a thin layer of mud, tighten it with wooden wedges on the pool wall, and place the hook head on the wooden wedges to keep the hook surface level and prevent it from tilting into the kiln due to unstable center of gravity when laying the breast wall.
2) When the hook bricks are dry-stacked, the upper surface should be leveled with a level ruler. Leave a 1 to 1.5 mm expansion joint between each hook turn, pad the joint with horse manure paper, and pull it out after laying. However, no expansion joint is left between the hook bricks facing the I-beam column, and a 5 mm expansion joint should be left between the hook surface of the hook brick and the cast iron plate.
3) No expansion joint is left between the upper gap brick and the large arch. Each brick is hammered solid. The back of the upper gap must be clamped tightly. The contact surface between the small surface and the large arch corner is required to be sealed with mud, and the contact surface between the large surface and the large arch brick is required to leave a gap of 3~5mm.
4) The corundum breast wall casting mouth faces outward.

The construction of the arch is the most critical. The arch span of this melting furnace is mm. The arch is built with 400mm thick silica bricks, weighing about 312.6t. This project adopts an insertable small furnace mouth (8 pairs in total), so there is no reverse arch on the arch.
Arch construction process: arch center line layout → arch brick pre-arrangement → masonry control line, each section expansion joint control line layout → arch brick stacking → arch brick masonry → arch brick locking → cleaning, grouting → tightening tie rods → jointing, cleaning.
After the installation of the arch tyre is completed, carefully check and adjust the span, arch height, tread curvature and arch top elevation. First, the longitudinal center line and the expansion joint line of each arch brick are marked on the arch tyre to pre-arrange the arch bricks. During the pre-arrangement, a ring is pre-arranged at both ends of each arch section, and the size of the mortar joint is determined by the actual size of the on-site pre-arrangement. Install a pre-made large arc keel frame at the end of the arch and the expansion joint. This frame should be 20-30mm higher than the arch brick, so that it is convenient for pulling the wire.
In order to ensure the overall beauty of the large arch surface and no misalignment, a parallel control line is laid out according to the thickness of the arch bricks in 3 rings as the masonry reference line. The position of the temperature measuring hole brick is laid out based on the center line of the 1# small furnace. Control points are also popped out on the keels at both ends of each section. This point is the reference for pulling the wire on each ring of the arch brick surface. After the laying out work is completed, 1/5 of the bricks used for the entire large arch are stacked on the arch formwork, and the load-bearing condition of the arch formwork is observed. If there is no abnormality such as sinking, the masonry of the large arch can be started.
Large arches are generally divided into 5 to 7 sections, each section is between 5 and 8 meters long. In order to ensure the overall quality of the column arch, masonry should be completed in a relatively short time to ensure that the bricks are locked before the mortar dries. It is not suitable to have too many people when masonry large arches. Generally, 6 technicians are arranged for each section. During construction, masonry should be symmetrical, and each row of arch bricks should be laid from both ends to the middle at the same time, and the speed should be consistent. There are 3 technicians on each side of each section, and each ring is masonry longitudinally, and the upper wire is drawn from both ends to the middle.
If bricks need to be processed, put the processed bricks in the middle, that is, the center of the column in the middle of each section, and the upper and lower rings should be staggered. The processed bricks cannot be less than 130mm.
It is strictly forbidden to put the big and small heads of arch bricks upside down during masonry. Each brick should be masonry, and the mortar fullness of the flat joints and top joints should reach more than 95%. Use a rubber hammer or a wooden hammer for correction. After each ring is built, use a card to check the angle of the arch bricks, and use a mm aluminum ruler to check the flatness.
After 20 rings are laid on each side, the remaining number of rings is pre-arranged again. If there is no change, continue construction. When there are 15 rings in the middle, pre-arrange again. If there is any change, adjust. The last three rings are staggered and laid at the same time, leaving a ring of lock bricks. The lock bricks should be left in a ring off the center, so that it is convenient for the laying of temperature measurement hole bricks. The protruding part of the lock brick should be left at 100-120mm.
After the same section is laid, the lock bricks are driven in uniformly. When driving the lock bricks, a wooden board must be placed on the arch bricks, and the big wooden hammer cannot directly contact the arch bricks. After the entire arch is locked, clean the arch top and fill the seams with diluted mud. The allowable size deviation of the concentrated expansion joint of the arch is 0-+2mm, and the surface tooth misalignment of the arch brick is less than 2mm. After the kiln is baked, the large arch expansion joint is filled with silica bricks and silica hot patching materials.
Tighten the tie rods immediately after the arch is built. Before tightening the tie rods, remove the temporary fasteners on the steel parts and the wooden wedges on both sides of the breast wall. Tightening the tie rods is to make the brick body of the entire arch and the supporting steel structure become a whole. The amount of tightening data is determined by the size of the arch collapse, and is roughly controlled at about 1‰ of the arch span. Generally, the method of directly observing the changes in the arch crown is adopted to observe how much the arch crown bulges upward after being subjected to the horizontal tension of the tie rods to reflect the force of the arch crown.
Mark the measuring point positions near the tie rods at the head, middle and tail of each arch section, in the middle and on both sides of the arch section. Use a level and a ruler to measure the elevation value of the arch when the tie rods are not tightened at the measuring point, and then measure the changes in the elevation values of each measuring point every time the tie rods are tightened and record them until the arch value reaches the expected value.
When tightening the tie rod, use a special wrench and sleeve to tighten the nut from the arch head to the arch end one by one. Arrange operators at both ends of each tie rod to tighten the nut slowly at the same time and with the same force, but do not tighten it at one time, but repeat it back and forth. Rest for about 1 hour in the middle of each cycle until the arch is tightened and bulges upward, so that the ruler shows a reading.
Then proceed at a speed of 2mm per hour until it reaches 1‰ of the arch span. During the process of tightening the tie rod, if it is found that the size of the bulge on both sides of the arch is asymmetrical, temporarily fix the steel column on the side with the larger reading, tighten the tie rod nut on the side with the smaller reading, keep it symmetrical, and then remove the temporary fixings to ensure that the two sides of the arch brick are symmetrical and balanced until the arch brick is separated from the barrel wood mold. After tightening to the design value, keep it for 24 hours for observation until the value no longer changes, and then start to remove the mold after inspection and confirmation.
Remove the wooden wedges under the columns, let the entire wooden formwork fall about 100mm, check the overall condition of the arch, and then use wooden strips to push up to separate the plywood and strips on the arch, and then remove the wooden formwork, clean it up and transport it out. Check whether there are arch bricks with broken corners, cracks, inversions, etc. on the lower arc surface of the arch. If there are any, they should be replaced in time, and then the joints should be pointed and cleaned. After inspection, the construction of the arch has met the design requirements, and then a comprehensive and thorough cleaning is carried out, and finally the bottom bricks of the pool are laid, and the exit is protected until the kiln is ignited.
Refractory ceramic fiber is important for high-temperature insulation. Many industries use ceramic fiber for insulation in refractories. It can handle very high heat and helps save energy. The worldwide market for refractory ceramic fiber products is growing fast.
Ceramic fiber coatings and mixes come in different types. Each type has a special job in insulation for refractories. Some types are moldables, pumpables, topcoats, caulks, coating cements, rigidizers, tamping mixes, and Moist-Pack blankets. Some products, like Silplate Mass , protect against wear and flames in high heat. Others, like RESCOBOND , stick well to refractories and set quickly. Knowing the differences between ceramic fiber coatings and mixes helps people get better insulation and longer-lasting refractories.
Refractory ceramic fiber coatings and mixes give strong insulation. They help save energy and can handle very high heat in factories.
There are different types like surface coatings, cements, moldable mixes, and vacuum-formed shapes. Each type has a special job to protect and make refractories stronger.
Ceramic fiber products can resist chemicals. They can also handle fast temperature changes and stay strong. This makes them great for furnaces, kilns, and fire safety.
It is important to use ceramic fiber products safely and take care of them often. This helps keep workers healthy and makes the insulation last longer.
Picking the right ceramic fiber product depends on what the job needs. Experts can help choose the best one for strong and long-lasting insulation.
Refractory ceramic fiber coatings and mixes have different main types. Each type does a special job in insulation and refractories. The main groups are surface coatings, cements and adhesives, moldable mixes, and vacuum-formed shapes. These products use advanced ceramics like alumina, silica, and zirconia. Makers use melting, blowing, and spinning to make fibers with special features. Picking the right type and mix changes how well it works, how long it lasts, and how strong it is in tough jobs.
Surface coatings help protect ceramic fiber products from tough places. There are two main kinds of coatings:
Fiber-matrix interfacial coatings: These make a weak link between the ceramic fiber and the matrix. This helps cracks move around fibers instead of breaking them. The coating makes the product tougher and stops it from breaking fast.
External high-temperature protective coatings: These include thermal barrier coatings and oxide films. They keep heat, rust, and damage away from the surface. Special ways like plasma spraying, chemical vapor deposition, and sol-gel processing put these coatings on.
Note: Surface coatings give strong protection against heat and chemicals. They keep ceramic fiber modules safe in gas turbines, rocket engines, and furnace linings.
A common surface coating uses a mix of about half silica sol and half alumina particles. Silica sol holds everything together, and alumina platelets help with heat and stop shrinking at high temperatures. For example, this mix can lower shrinking from 4.3% to 1.5% after heating at °C for 8 hours. This helps ceramic fiber boards stay strong and stable when hot.
Yufeng Refractory makes surface coatings that resist high heat and wear. Their coatings help ceramic fiber modules and boards last longer in furnaces and kilns.

Cements and adhesives stick ceramic fiber products to other refractories or metal. These materials need to handle high heat and stay stuck. There are many kinds of cements and adhesives:
Calcium aluminate bond: Used in polycrystalline ceramics and aggregate-based refractories.
Carbon bond: Made by turning organic binders into carbon, good for carbon-carbon composites.
Portland cement / calcium silicate bond: Used in concrete and some refractories.
Phosphate bond: Sets fast, used for special jobs.
Silicate / clay bond: Used in polycrystalline ceramics.

Better insulation for less money
Yufeng Refractory makes vacuum-formed shapes for high heat jobs. Their products include custom shapes for furnaces, kilns, and foundries. These shapes keep insulation and strength even in very hot places.
Ceramic fiber products use different mixes to get special features. Zirconia fibers have mostly zirconium dioxide, which gives great heat and chemical stability. Alumina fibers use crystalline α-Al2O3, sometimes with iron oxide and silica to make them stronger. Alumina–silica fibers mix alumina and silica, sometimes adding boron oxide to make fibers stronger. Alumina–zirconia fibers mix alumina, zirconia, and yttria for more flexibility.
Makers use different ways to make ceramic fiber products:
Centrifugal spinning: Melts ceramic at high heat and spins it fast. This makes bigger fibers that are less flexible but quick to make.
Solution blow spinning: Uses a solution with polymer to make fibers. This way is fast and can make 2D and 3D fiber shapes.
Electrospinning: Makes small, even fibers from a polymer solution. This way can use many mixes but is slower.
Each way changes fiber size, flexibility, and strength. Fibers with more parts, like those with yttrium oxide or alumina, bend better and stand up to heat.
Tip: Picking the right mix and way to make it gives the best results for high heat jobs.
Refractory ceramic fibers are some of the best materials for high heat insulation. They are very important in factories that need to handle high heat, strong chemicals, and heavy use. The way these fibers are made and what they are made of changes how they work. Most of these fibers have a special shape that makes them bendy and tough. When they get really hot, some fibers can change their shape, which can change how they work. When you compare them to other man-made fibers, refractory ceramic fibers keep heat out better and last longer in rough places.
Ceramic fiber products are great at keeping heat in or out. This makes them a top pick for places that get very hot, like factories. They do not let heat move through them easily, so machines use less energy and stay safe. These fibers can take heat from °C to °C, which is good for furnaces and kilns.
Ceramic fiber modules can handle high heat and still work well after a long time.
They are light and bendy, so you can put them in many shapes.
They do not hold much heat, so they cool down fast. This helps when machines turn on and off a lot.
The fibers do not break when the temperature changes quickly.
They are made from things like alumina and silica, and sometimes zirconia is added for more heat resistance.
Note: You can get ceramic fiber insulation as blankets, boards, modules, or paper. Each type is made for a different job in hot places.
Key benefits of ceramic fiber insulation:
Stops heat from escaping and saves energy
Works well at very high temperatures
Keeps machines from getting too hot
Can be used in many places like furnaces, boilers, reactors, and fire barriers
Ceramic fiber insulation works better than old-style bricks for keeping heat in. It lets less heat pass through, which saves money on fuel and helps machines last longer.
Ceramic fiber products do not get damaged by many chemicals, like acids, bases, or oils. This means they last a long time, even in tough places with lots of heat and chemicals. The fibers do not react with most things, so they keep working well.
Ceramic fiber insulation keeps its strength when it touches strong gases or liquids. The main parts, alumina and silica, and sometimes zirconia, help stop rust and damage. This makes them good for chemical plants and refineries where there are lots of harsh chemicals.
Tip: If you need extra protection from chemicals, pick ceramic fiber products with zirconia or other special parts.
Main advantages of chemical resistance in ceramic fiber insulation:
Stops damage from acids, bases, and oils
Keeps working in places with lots of chemicals
Makes refractories and machines last longer
Cuts down on repairs and new parts
Ceramic fiber products are strong and can handle tough jobs. Their special shape lets atoms move more, so they bend and do not break easily. This makes them stronger than other ceramics.
Ceramic fiber mixes can be squeezed or bent without breaking. Their strength depends on how much fiber is inside and how hot it gets. The best mix has about 4% fiber, which makes it very strong at room temperature. When it gets hotter, it gets weaker, but it still works for most hot jobs.
They stay strong and stretchy even above °C.
The way the fibers are woven helps stop cracks from spreading.
The special shape lets them bend more before breaking.
Ceramic fiber boards and modules keep their shape and strength even after being used many times in hot places. This helps keep refractories safe and working for a long time.
Thermal shock resistance means ceramic fiber insulation can handle quick changes in heat. These fibers do not crack or stop working when the temperature goes up or down fast. This is important for refractories that heat up and cool down a lot.
Ceramic fiber mixes, like Si-Al-C-O and Si-Ti-C-O, keep about 90% of their bending strength after being shocked by heat up to °C. Some special fibers can work all the time at °C and last even longer.
Ceramic fiber insulation is light, so it heats up and cools down quickly.
The fibers are bendy and do not expand much, so they do not crack when the temperature changes.
They handle heating and cooling better than old insulation, which is good for factories.
Note: A carbon layer around the fibers helps stop cracks from heat stress, so the fibers stay strong after sudden temperature changes.
Key points about thermal shock resistance:
Keeps working and stays strong after fast heating or cooling
Lowers the chance of cracks and machine problems
Helps refractories stay safe and last longer
Ceramic fiber insulation is strong, keeps heat in, resists chemicals, and does not crack with fast temperature changes. These features make it the best choice for hot places in factories and other industries.
Factories use ceramic fiber insulation in many hot jobs. Workers put ceramic fiber blankets and boards on furnace walls. These products help keep heat inside and save energy. Ceramic fiber modules fit tricky shapes and are simple to install. They can handle quick changes in heat and last a long time, so repairs are needed less often.
Ceramic fiber insulation spreads heat evenly, which helps make better products in factories.
Benefits in furnace applications:
Great at keeping heat in
Light and bendy materials
Fast to put in and easy to fix
Lasts a long time
Boilers and kilns need strong insulation for very hot jobs. Workers use ceramic fiber boards and modules to cover boiler and kiln walls. These products are tough and do not let much heat pass through. Modules go in fast and do not need drying or special steps. Special anchors keep metal parts away from the hottest spots, so things last longer.
Ceramic fiber castables are good for odd kiln shapes. They are strong and can handle quick heat changes.
Ceramic fiber insulation is important for stopping fires from spreading. Ceramic fiber boards, blankets, and papers block fire and heat. These products can take high heat and do not burn or melt.
Ceramic fiber boards have top fire ratings, so they are great for fireproof walls, ceilings, and doors.
Common fire protection applications:
Fireproof doors and walls
Fire safety for steel beams
Joints that can get bigger and heat shields
Ceramic fiber blankets stay strong when pressed or heated, so they help control heat during fires.

Typical applications:
Lining furnaces and kilns in factories
Insulating heaters and heat exchangers in refineries
Extra insulation behind refractory bricks
Ceramic fiber insulation has good heat properties, resists chemicals, and lasts long. These things help lower repair costs and make places safer where the work is tough.
Handling refractory ceramic fiber products in hot places needs care. Workers can breathe in fibers or get them on their skin and eyes. This can make skin, eyes, or lungs feel sore. To stay safe, workers should do these things:
Wear long sleeves and gloves to keep skin safe.
Put on head and eye gear, and use masks or respirators to stop breathing dust.
Wash skin with soap and water after touching fibers.
Wash work clothes by themselves and do it often.
Do not eat, drink, or smoke near the work area.
Clean work areas often to keep dust away.
Use HEPA filters or wet sweeping to clean up dust.
Never use air blowers to clean clothes or surfaces.
Do not use power tools for cutting or drilling.
Always follow safety rules from the maker and OSHA.
Workers should know refractory ceramic fiber might cause cancer. Using the right gear and following safety steps helps keep people healthy.
Refractory ceramic fiber coatings and mixes last a long time in hot places. They do not break down easily and can stand up to rust. These coatings and mixes can last for years in refractories. Most ceramic fiber blankets last five to ten years if used in steady heat. Modules can last three to five years or more if put in right. How long they last depends on heat, chemicals, and how well they are installed. Good heat resistance and stability help them stay strong and not rust, even in tough spots.
Taking care of refractory ceramic fiber coatings and mixes helps them last longer in hot places. Workers should do these things:
Heat and cool slowly to stop thermal shock.
Write down all checks and repairs.
Teach workers the right way to work with high heat.
Plan shutdowns to check and fix things.
Check anchors often and keep them working well.
Follow the maker’s rules for putting things in.
Use surface coatings and check them often.
