The medium frequency induction electric smelting furnace mainly consists of medium frequency power cabinet, compensation capacitor bank, smelting furnace body (steel shell furnace, aluminum shell furnace), water-cooled cable, hydraulic station, tilting furnace control box, etc. Mainly used for melting steel, iron, copper, aluminum, and alloys, it has high melting efficiency, good energy-saving effect, uniform metal composition, low burning loss, fast temperature rise, and easy temperature control, suitable for various metal melting occasions.

According to the medium frequency power supply technology, it can be divided into parallel technology and series technology. Series parallel connection refers to the connection method between the induction coil and the resonant capacitor. Parallel technology is a traditional medium frequency power supply technology that is mature and reliable, has a low failure rate, is cheap, but consumes high power, and is generally suitable for small furnaces of 0.5 tons and below. Series technology is an international mainstream medium frequency power supply technology, which is energy-saving and efficient (up to 30% more than parallel equipment), has a complete protection system, is stable and easy to use, supports personalized customization (one to two, one to three, etc.), and has a higher price than parallel equipment. It is generally suitable for large furnaces with a capacity of 0.5 tons or more.

According to the type of furnace body, it is divided into aluminum shell furnace and steel shell furnace. Aluminum shell furnace is a traditional furnace body that uses a thickened aluminum alloy shell and a reducer to pour molten iron. It is cheap and suitable for small furnace types of 0.5 tons and below. The shell of the steel shell furnace is made of thickened steel structure, equipped with a magnetic yoke to shield magnetic field leakage. It adopts a hydraulic tilting furnace, which is safe and reliable, and suitable for large furnace types of 1T and above.
