A Review of Optimization Methods for Temperature Uniformity of Transverse Flux Induction Heating

The traditional heating method requires a high-temperature heat source to heat the surface of the object by radiation and conduction, and then gradually heat the interior of the object by conduction and convection. The heating speed is slow and the efficiency is low. The traditional heating of coal, gas and oil has the problems of serious pollution, slow heating and uneven heating. Compared with the traditional heating method, induction heating can adjust the heating depth, heating area and heating speed more accurately. It adopts non-contact heating method, which is easy to control and adjust, so as to realize the automation of heating process. Induction heating technology has a series of superior performance and characteristics, which makes it develop rapidly in just a few decades. Firstly, this paper introduces the concept of transverse flux and longitudinal flux induction heating and compares the technical characteristics. Secondly, it briefly introduces the solution software of eddy current field and temperature field calculation, and expounds the method of improving the temperature uniformity at the outlet of transverse flux induction heating strip from various angles. Finally, the problems existing in transverse flux induction heating technology are summarized and the preliminary research direction is put forward.
