Abstract：Abstract: In this paper, through thermal simulation experiments, the dynamic CCT curve is drawn, the cooling rate, phase transformation time requirement and phase transformation temperature range of DP600 in production are defined. According to the dynamic CCT curve, combined with the heating, cooling and post-coating cooling capacity of the horizontal annealing furnace in the hot dip galvanizing line, the DP600 dual phase steel is successfully developed through the results verification of thermal simulation experiment.
