Induction melting furnace is a furnace that converts three-phase power frequency current into single-phase intermediate frequency current, and then induces metal eddy current loss through electromagnetic field induction, and finally achieves the purpose of heating and melting. It can be used for smelting, heating and heat preservation of ferrous or non-ferrous metals and alloy materials such as iron and steel, copper and aluminum. Mainly used in metal casting, steelmaking and other industries.Induction melting furnace is divided into steel shell furnace and aluminum shell furnace.
