Electromagnetic Field Parameters during the Induction-Resistive Heating of Ferromagnetic Materials
摘要
Abstract
The authors study the parameters of the electromagnetic field when heating ferromagnetic steels in induction-resistive heating devices. New ways of calculating are obtained, and characteristics of electromagnetic fields in multilayer systems are determined. An estimate is made of the effect an internal copper layer of a heater, an air gap between layers, and the inductor current have on the parameters of the electromagnetic field.
