METHOD AND APPARATUS FOR PRODUCING A MINI-SPANGLE AND A ZERO-SPANGLE STEEL SHEET

摘要

The manufacturing equipment improves the quality of the galvanized steel strip by preventing the formation of cracks and reduces the manufacturing cost by automation and recycle of chemical solutions. The equipment comprises: (A) a cooling box(12) with a transfer car equipped with a travelling device and a lifting device; (B) air mixing nozzles(14) to spray chemical solution and high pressure air on the strip for mini-spangle pattern; and (C) high pressure nozzle(16) to spray high pressure potable water on the strip for zero-spangle pattern.
