Analysis of Line Heating Using Induction Heating

Induction heating process includes magnetic and thermal situations. In order to analyze the induction heating, material properties depending on temperature are considered. In this paper, three dimensional analysis of induction heating process for moving inductor is analyzed using moving coordinate. The skin effect is confirmed inside the steel plate in the electro-magnetic analysis. The heat generation at the initial state is different from that at the quasi-stationary state. Therefore, material properties depending on temperature must be considered. The results of finite element analysis agree well with the experimental temperature results.
