Simulation of induction heating device with double inductors for continuously heating up steel bars

The whole design and simulation procedure for an induction heating device with double inductors is presented. To obtain a more accuracy solution, a FEM simulation of the coupled electromagnetic-thermal problem was completed, taking into account the interaction between the inductors, the power supply source parameters and the resulted load parameters. The simulation method is validated in the design of induction heating equipment and the procedure presented is proven to be efficient in the overall design of induction heating equipment. The experimental results are discussed, which is helpful for design of induction heating device.
