Abstract: Colors were generated by preferential oxidation of the metals in coloring hot dip galvanization process, and the evolution of temperature field during cooling after hot dip would be responsible for the coloration results directly. The influences of bath temperature and velocity of steel strip moving on temperature field of the strip were calculated in continuous coloring hot dip galvanization process by means of the ANSYS/Thermal module. The factors were considered including convection heat transfer, latent heat during cooling, and heat radiation in calculation. The effects of temperature field on coloration of sheet steel samples were investigated.
Key words:  coloring hot dip galvanization; temperature field; coloration
