The medium-frequency induction furnace is an industrial device that utilizes the principle of electromagnetic induction to heat metals, primarily used for pre-forging heating, metal smelting, and heat treatment. It is widely applied in fields such as mechanical manufacturing and cast iron production. The working principle of the induction melting furnace involves converting three-phase industrial frequency alternating current into adjustable medium-frequency current (60Hz to 10kHz), generating an alternating magnetic field through induction coils, and inducing eddy currents in the metal material to produce heat.
