Equipment Name: Hot dip coil galvalume line
1. Main Introduce
The SIONPOWER cold-rolled steel strip send to continuous hot-dip galvalume line to electrolytic cleaning, and then send to be annealed in the continuous annealing furnace. After annealed, dip the plate in the molten zinc pot for hot-dip galvaluming. The product is finally formed after finishing, straightening, and passivation process.
The galvalume strip is a long and narrow strip of steel, which is coated with a different degree of the raw material called (zinc). The hot dip galvalume has the advantages of even coating, strong adhesion and long service life, etc. The complex physical and chemical reaction in the bath of hot dip galvalume steel substrate and melting, forming a resistant compact structure the anti-corrosion of Zn Fe alloy layer. The alloy layer is integrated with the pure zinc layer and the strip matrix. Therefore, its corrosion resistance.
