It is then heated to 710~920 ℃ in a reduction annealing furnace containing a mixture of H2 and N2 gas to reduce the iron oxide film to sponge iron. The surface activated and purified strip steel is cooled to a temperature slightly higher than that of molten zinc, Enter a zinc pot at 450~460 ℃ and use an air knife to control the surface thickness of the zinc layer. Finally, Sheet Metal Part it is passivated by chromate solution to improve white rust resistance.
