Abstract: Under the premise of considering variation of the strip physical property parameters with temperature, the influence of different excitation current, current frequency and strip movement rate on steel strip temperature distribution was analyzed based on the iterative calculation of transverse flux induction heating coupling field. By changing the air gap distribution between the heater and the strip, the original induction heater model was optimized and other four induction heater models were designed, and the average temperature and temperature uniformity of the strips under different heater models were analyzed. The average temperature and temperature uniformity of the 45 steel and 35CrMnSiA steel under the original heater model and the improved optimal heater model were compared. The results show that the optimized induction heater model makes the surface temperature distribution of the strips more uniform and the average temperature higher.
