Abstract
Specific features of induction heating are considered, which must be taken into account when designing and operating INU. The decisive role of the configuration of the temperature field is emphasized to achieve the required heating quality. In this case, the presence of edge effects, both longitudinal and transverse, is characteristic for inductive heating. Moreover, the former are present when both cylindrical and rectangular preforms are heated. The degree of manifestation of the transverse edge effect depends on the electrical and thermal properties of the heated metal, the dimensions of the cross section, the frequency of the inductor current and the magnitude of the heat losses. Electromagnetic processes in the inductor-metal system of a rectangular shape are characterized by electrodynamic forces and associated vibrations and noise.
