An electric furnace converts electrical energy within the furnace into heat to heat the workpiece. Electric furnaces can be categorized as resistance furnaces, induction furnaces, arc furnaces, plasma furnaces, and electron beam furnaces.
Compared to fuel-fired furnaces, electric furnaces offer advantages such as easy atmosphere control, rapid material heating, high heating temperatures, easy temperature control, ease of mechanization and automation of the production process, improved labor hygiene, high thermal efficiency, superior product quality, and environmental friendliness, contributing to the alleviation of increasingly serious environmental problems.
