Dross formation; Continuous Galvanizing Bath; Numerical modeling; Strip Entry Temperature
Achieving a good and stable thermal field and controlling the content of aluminum and iron in the continuous galvanizing bath operations are of critical importance in achieving automotive quality coated steel products. Due to the prior over-aging heat treatment, the strip entry temperature for advanced high strength steels (AHSS) may be different from the mean bath temperature. Such temperature difference may have significant impacts on the bath thermal field and consequently the dross formation patterns, potentially hampering the quality of the coating surface.
