Abstract:Static induction heating of steel plate is studied,2D numerical model of
   electromagnetic-thermal coupling is developed by COMSOL Multi-Physics
   software,and the numerical results of temperature agree with
   experimental data.Distributions of electromagnetic field and temperature
   field in the heating process of the steel plate are studied.After the
   inductor has been fitted with a magnetizer,the Joule heat generated by
   eddy currents is converged under the inductor,and the heat efficiency is
   improved.Finally,the influences of the process parameters of induction
   heating on temperature are studied,and the experimental results show
   that,under the conditions that the other parameters remain unchanged,the
   higher the current of the inductor and the current frequency are,the
   faster the plate is heated,and the bigger the gap between the inductor
   and the plate is,the slower the plate is heated.
