Performance of hot-dip galvanizing equipment
Hot Dip Galvanizing Equipment
The base material of hot dip galvanizing is zinc. Zinc is naturally present in air, water and soil. Zinc plating can protect the material covered under normal conditions for up to 40 years. Hot dip galvanizing is durable, durable, economical and recyclable.
Hebei Annuo - Hot Dip Galvanizing Equipment Chinese Manufacturer
Hot dip galvanizing equipment aims to make full use of the galvanizing process. The resettlement plan will be determined according to the construction of the facility, the implementation of the project and the construction area of the facility. Hebei Annuo is a global provider of Hot Dip Galvanizing Plant and Solutions, Specialty General HDG plant design and manufacture service. If you have any questions about anything, you can ask us!
Made of 100% copolymer and homopolymer polypropylene, a durable long-life material that will not delaminate or become brittle even if exposed to corrosive chemicals for a long time.
The manufacturing and construction are convenient, the quality and performance are reliable, the durability is strong, and the function is strong. Flexible settings and easy maintenance. Strong acid and alkali resistance, anti-falling.
It is made of special steel plate XG08, with low chemical composition of C, Si, S and P, and has the characteristics of corrosion resistance and long service life. Before cutting, perform ultrasonic inspection on XG08 steel plate, and start cutting if the plate is intact. Zinc Kettle will also undergo ultrasonic testing before delivery.
Natural gas heating can ensure even heat distribution around the zinc kettle without local overheating. The steel structure of the furnace body is welded by section steel and steel plate, and the material is high-quality carbon steel. And strictly control the welding deformation to ensure the rigidity and strength of the furnace.
The tube heat exchanger is installed on the furnace flue (heat exchange temperature is 90°C-100°C). The hot water is pumped into the expansion tank through the hot water circulation pump, and then enters the PP radiator to heat the solvent to ensure the temperature of the solvent tank At 65°C±5°C.

Hot-Dip Galvanizing Process
Hot-dip galvanizing is the process of coating iron and steel with zinc, which alloys with the surface of the base metal when immersing the metal in a bath of molten zinc at a temperature of around 840 °F (449 °C). The process of hot-dip galvanizing line results in a metallurgical bond between zinc and steel with a series of distinct iron-zinc alloys. The resulting coated steel can be used in much the same way as uncoated.
Oil Removal
First the steel is immersed in an acid degreasing bath or caustic solution to remove organic contaminants such as dirt, oil, and grease from the surface of the steel. After degreasing the steel is rinsed with water.
Surface Cleaning With Acid Treatment (Pickling)
Next the steel is pickled in a dilute solution of either hydrochloric or sulfuric acid.
Rinsing
For a good reaction with zinc the metal must be dry.
Flux
A flux, often zinc ammonium chloride is applied to the steel to inhibit oxidation of the cleaned surface upon exposure to air. The flux is allowed to dry on the steel and aids in the process of the liquid zinc wetting and adhering to the steel.
Drying
For a good reaction with Zinc the metal must be dry.
Hot-Dip Galvanizing
Hot-Dip Galvanization is a type of galvanization. It is the process of coating iron and steel with zinc, which alloys with the surface of the base metal when immersing the metal in a bath of molten zinc at a temperature of around 449 °C.
Cooling
Galvanized products are cooled in air or by immersing into a water bath.
Passivation
It is about the formation of a protective surface on the zinc to improve corrosion protection.
Leveling
After the galvanizing process of the materials, the burrs and deposits formed on the surface are cleaned and packed according to their sizes.
