Numerical Simulation of Channel Induction Furnace to Investigate Efficiency for Low Frequencie


Abstract

The foundry industry worldwide commonly uses channel induction furnaces to heat and melt alloys. The operating frequency is one of the main issues when constructing an effi-cient channel furnace. It is possible to choose operating frequencies lower than 50 Hz using a modern IGBT power converter. This work shows the simulation results using ANSYS with the goal of finding the best electrical frequency necessary to operate the induction furnace. First, a two-dimensional model is used to calculate the efficiency depending on frequency. Then, the channel model is extended to a more realistic three-dimensional model. Finally, the influence of frequency, inductor profile, and several components of the induction channel fur-nace are discussed.
