Hot galvanizing (also called hot dip galvanizing) is a kind of effective metallic anti-corrosion mode and mainly applied to metallic structure facilities in various industries. A steel piece subjected to rust removal is dipped into melted zinc at the temperature of nearly 500ºC, and a zinc layer is coated on the surface of the steel structure piece, so that the aim of resisting corrosion is achieved. The flow of the hot galvanizing: acid cleaning of finished products-water washing-adding of auxiliary plating solution-drying-rack plating-cooling-medicinal chemistry-cleaning-grinding-finishing of hot galvanizing. The hot dip galvanizing process is developed from old hot plating methods, and it has a history of over 140 years since its application to the industry of France in 1836. However, the hot dip galvanizing industry has been greatly developed in recent three decades with the quick development of cold-strip steel.
With excellent cold-rolling steel strips as a base material, it has the advantages of good manufacturing performance, high impact resistance, uniform plating thickness, high adhesive force, no peeling after forming and high corrosion resistance, bright and smooth surface, accurate size, flat and straight plate surface, uniform spangles and beautiful appearance; it is subjected to passivation and oil coating treatment, and avoids deterioration after a short-term storage in a warehouse; and after the surface is cleaned, the product is a good base material for manufacturing anti-corrosion coating plates.
1. High product quality: The product completely conforms to GB3091-84 and BA139=87-87 standards;
2. High automaticity: The system adopts PC programmed control and the frequency conversion speed adjustment;
3. High production efficiency: Double-in double-out mode, and the annual output is 30,40,000 tons;
4. Low production cost: The adoption of advanced auxiliary plating agent iron removing technology guarantees that the content of Fe2+ in the solvent is lower than 0.6g/l on a long-term basis; and by adopting the technology, the consumption of zinc is reduced by 5 to 10kg for every one ton of finished products, and the coal gas is used as fuel;
