Abstract—In this paper, the three-dimensional dynamic model of slab induction heating and soaking process is established by finite element method. Two different width to thickness ratio slabs are simulated at contant speed through the heating process of the inductor and the subsequent soaking process. Then the temperature field diagram of induction heating and soaking at different moments was obtained, and the regularity and characteristics of temperature change during induction heating were analyzed. Finally the following conclusions are obtained, (1)the greater the width to thickness ratio of the slab, the greater the temperature difference after induction heating, (2)the reasonable setting of the soaking period will help the slab temperature tend to be uniform, and (3)the addition of the insulation cover can effectively delay the slab cooling.
