The Study of the Effect of Magnetic Flux Concentrator to the Induction Heating System Using Coupled Electromagnetic-Thermal Simulation Model

Induction heating is frequently used in the metalworking industry to heat metals for hardening, soldering, brazing, tempering and annealing. Due to its complexity, the using of simulation to analyze induction heating process could become very advantageous both in design and economic aspects. In this paper, an analytical model is established using commercial package Cedrat Flux® 10.3, and the model is verified by the experiments. After the establishment of analytical model, an analysis on the effect of magnetic flux concentrator was conducted.
