Numerical modelling of an innovative induction heating technique for aluminium extrusion process

The paper describes numerical models developed to simulate induction heating process for aluminium billet heating by rotation in a DC magnetic field. 2D and 3D numerical approach to coupled electromagnetic and thermal process modelling and the results of investigation are presented. Influence of rotation speed on temperature distribution in cross-section of the billet is investigated. Influence of electromagnetic effects on temperature distribution along the billet length is showed.
