Performance of hot-dip galvanizing equipment
Zinc plating of a wire is the process of applying a protective layer of zinc to its surface. Galvanized wire is always in demand in the market of metal products and is in great demand in construction and production, agriculture and transport companies. Currently, about one third of all wire produced is coated with zinc.
Zinc plating steel wire is a common and effective way to protect against corrosion. Zinc coating provides not only mechanical, but also electrochemical protection of products. Zinc itself has cathodic properties in relation to the base metal of the wire.
Zinc plating of wire, which will be little deformed during operation or must be used in harsh atmospheric and climatic conditions, is carried out with the application of a thickened protective layer using hot-dip galvanizing technology.
Mainly used for producing galvanized steel wire with thick zinc coating layer (50-300 g/m2), wire diameter: Ø1.0 - 4.0 mm
The hot dip galvanizing technology includes a number of sequential high strength coating operations. The coating with this technology is applied to fasteners (bolts, nuts, washers), wires, steel structure elements, rolled products, sheet metal, pipes and many other metalware. The surface of hot galvanized metal after the coating process should be smooth completely or slightly rough. The colour of the metalware coating has shades ranging from shiny silver to dark grey matte. High-temperature zinc-coated products, depending on the operating conditions, can provide metal corrosion protection for 50 years or more.
The sequence of the hot dip galvanizing process: wire feeding (coiled on the disc/coil) heat treatment (annealing/ degreasing, hardening) water cooling etching in hydrochloric acid solution to remove rust and scale rinsing washing in water to remove solution rinsing and flux salts fluxing to ensure high adhesion of zinc to the top layer of wire metal drying on a fast air flow hot-dip galvanizing steel wire rewinding to the coil.
The Hot Dip Galvanizing technological process is shown for reference only. The brass plating steel wire production line is designed and manufactured according to customer requirements.
