Abstract

Workpieces are needed to be induction heated to a fixed temperature uniformly in a certain situation. In order to explore feasible induction coil designs by using electromagnetic and heat transfer coupled analysis, pre-established current patterns to hold the workpiece temperature are needed.
In this study, we employed the method feedback temperature to control current during coupled analysis.
