Aspects Regarding the Numerical Modeling of the Electromagnetic Induction Heating Process Used for Hot Deformation of Semi-finished Parts

Abstract

The paper deals with numerical computation methods for solving the quasistationary electromagnetic field for ferromagnetic semi-finished parts placed into industrial inductor. Finite element method is used for eddy current problem solution initially for fixed ferromagnetic parts. The coupled question electromagnetic field and thermal field during induction heating process is solved. Power density as a function of amplitude and frequency of exciting current is evaluated. Thermal field distribution inside the semi-finished part is also quantified. These results are an essential phase in the design optimization of industrial induction equipment and the heating process.
