Abstract：Microstructure of IF steel was observed by OM with different annealing temperature and different work roll conditions in hot dip galvanizing(HDG) process, surface morphology was observed by OM and SEM with different work roll process, its Wsa with different annealing temperature and different work roll process were tested. The results show that the annealing temp. have no effect on the surface morphology, work roll roughness have effect on the surface morphology. When the annealing temperature increases, the grain size becomes big. Decrease the annealing temperature above the recrystal temperature, it can avoid the grain to grow up for recrystal grain, and the grain size is small and uniform. When the annealing temp. is 820 ℃, work roll roughness is 1.6?m, Wsa value is more better.
