Optimal design of an inductor for transverse flux heating using a combined evolutionary-simplex method

摘要

Transverse flux induction heating (TFH) is a process advantageously applied for the heat treatment of thin non-ferrous metal strips. In comparison with the better known longitudinal flux heating the design of TFH inductors is more complex. In fact both the prediction of power density distribution in the strip and the calculation of the thermal transient during the heating process require a solution of 3D electromagnetic and thermal problems.
