Abstract

The FEM model of electromagnetic-thermal coupled field was built up for 20 MnSi continuous casting square billet by using ANSYS software.The distribution of eddy current and temperature field was presented

and the simulated results were analyzed.The distribution of temperature and eddy current was visualized by simulation calculation under different induction heating parameters.In addition

influence of parameters on the induction heating was analyzed.The results show that parameters of current and frequency greatly affect the distribution of temperature and eddy current.Finally

simulation results were verified

and the simulated results were well agreement with the measured ones.
