摘　　要：为了在钢板加热过程中精确迅速地控制钢板的加热温度,结合电磁感应理论、温度微分方程和麦克斯韦方程组,建立了温度场与电磁场耦合的有限元模型,并应用有限元分析软件ANSYS-APDL对热加工工艺中常用的电阻加热法和电磁感应加热法进行了模拟与分析.研究结果表明:采用电阻加热法加热钢板时,板材厚度减小、加热时间增加会使钢板的最高加热温度升高,采用电磁感应加热法加热钢板时,电磁感应线圈直径的增加会使钢板的最高加热温度升高;在板材厚度一致、加热时间相同的情况下,电阻加热法升温速率慢,温度易于控制,电磁感应加热法升温快,加热效率高.In order to precisely and quickly control the heating temperature of the steel plate in the heating process, combining the theory of electromagnetic induction, the temperature differential equations and the maxwell’s equations, the finite element models coupling temperature field and electromagnetic field was built. And the resistance heating method and electromagnetic induction heating method used in heat treatment were simulated and analyzrd by using ANSYS-APDL of finite element analysis software.The results show that the highest heating temperature of steel plate in resistance heating method is increased with the decrease of plate thickness and the increase of heating time, and the highest heating temperature of steel plate in electromagnetic induction heating method is increased with the increase of electromagnetic induction coil diameter. Under the condition of the same thickness of plate and the same heating time, the resistance heating method has a slow heating rate and easy temperature control, while the electromagnetic induction heating method has a fast heating rate and high heating efficiency.
