A medium-frequency induction furnace is a furnace that heats metal through electromagnetic induction. The heating frequency typically ranges from 150 to 8000 Hz, falling within the medium-frequency range. Hence, it is named as a medium-frequency induction furnace. It consists of a variable-frequency device, furnace body, and front-end control unit. The advantages of the medium-frequency induction furnace are detailed.

Firstly, in terms of heating, the medium-frequency induction furnace boasts the advantage of fast heating speed, significantly outpacing the efficiency of other metal heating equipment. During operation, the furnace minimizes oxidation and decarburization of workpieces, effectively reducing material waste. The heating process ensures even heat distribution across the workpiece. Additionally, the medium-frequency induction furnace causes less environmental damage and consumes less energy. It will be an indispensable new equipment for future industrial production.

Medium-frequency induction furnaces are widely used. As the main equipment in the forging and casting industries, they have made significant contributions to the basic forgings and castings for the mechanical industry. These furnaces are extensively employed. The raw materials required by the mechanical industry are essentially processed using medium-frequency induction furnaces. For example, medium-frequency induction furnaces in the forging industry are used to heat the metal billets prior to forging. In the forging industry, they are known as medium-frequency heating furnaces, through-heating furnaces, medium-frequency through-heating furnaces, and heating furnaces; in the casting industry, medium-frequency induction furnaces are used for remelting and purifying scrap metals. They are referred to as medium-frequency melting furnaces, one-drive-two melting furnaces, melting furnaces, series resonance medium-frequency furnaces, aluminum melting furnaces, copper melting furnaces, and more; in the heat treatment industry, there are many medium-frequency induction furnaces used for metal quenching and tempering, while medium-frequency heating furnaces are typically used for reinforcing steel quenching and tempering.
