Research of various inductors configurations for heating titanium slabs

Abstract

In this paper various inductors configurations for heating a titanium slab, as well as the influence of frequency changes on efficiency of inductors are considered. The calculations are carried out by means of finite element method. In this research a three-dimensional time-harmonic model in A-formulation of Maxwell's equations is used. In the framework of this work, only electromagnetic problem was calculated, since the main aim of this work is to assess the effectiveness of inductor configurations in terms of electromagnetic problem. Efficiency of inductor and the uniformity coefficient introduced herein have been chosen as the comparison parameters. Ultimately, distribution of electromagnetic power density in the workpiece is shown, also conclusions are drawn for each of inductor configurations. © Published under licence by IOP Publishing Ltd.
