Optimal Solutions for Uniform Heating of a Non-Ferrous Bar by Electromagnetic Induction, Using Numerical Modeling

The paper intends to present the numerical modelling of the electromagnetic phenomena coupled with the thermal ones when processing the semi-finished products made up of non-ferrous alloy, through electromagnetic induction with the purpose of obtaining a homogenous heating of the pieces in the shortest time. The purpose of the numerical modelling in this paper is to check cheap solutions to homogenize the intensity of the magnetic field according to the geometry of the inductor, by using a magnetic field intensifier or if it is possible to use the motion of the pieces inside the inductor.
