Abstract

AbstractInduction and microwave plants, which can increase the productivity and quality of products, are used in various technological processes. The use of electromagnetic waves of various frequencies to heat materials is common in these processes. Induction heating is widely used in various technological processes for heat treatment and melting of conductive materials. Microwave heating is used to intensify the heat treatment of various dielectric materials. An urgent task is to develop energy-efficient induction and microwave plants that meet the increased requirements for the quality of products. For this purpose, mathematical simulation of electrodynamic and thermal processes during copper melting in an induction crucible furnace and in a microwave plant for thermal modification of composite materials. The simulation was carried out using the COMSOL Multiphysics software product. The distribution of the electromagnetic and thermal fields in the induction plant was obtained. The efficient process parameters of melting were determined and the crucible material was selected. A model of a conveyor-type microwave electrotechnical plant for the modification of polymer composite materials was developed. The distribution of the electric field strength and temperature in the working chamber for microwave modification of composite materials was numerically studied.
