Abstract：The microstructure of HRB400E was decided by the cooling process after laying. The different cooling processes were simulated by Gleeble-3500 thermal simulation tester. The dilatometric curve and microstructure were analyzed under different cooling processes. The results indicate that the cooling rate and mutational temperature greatly influenced the final microstructure. The rational cooperation of these two parameters could dominate the fraction of bainite. With the increasing of cooling rate and decreasing of mutational temperature，the fraction of bainite enhanced.
