The diathermy furnace designed by the principle of induction heating is mainly composed of KGPS intermediate frequency power supply and electromagnetic sensor. Compared with other heating furnaces, the advantages are obvious. If the heating rate is fast, the heating time is short, the productivity can be doubled; the continuous production line can be formed with other process equipment; the heating efficiency is as high as 60~75%, which is 20% higher than the flame heating efficiency and 40% higher than the heating efficiency of the resistance furnace; Induction heating process does not produce flue gas and smoke, energy saving and environmental protection; high degree of automation, especially suitable for the production of product parts with simple blank shape, small variety and large output. Due to its many advantages, it is rapidly eliminating the use of flame heating and resistance heating devices, and is widely used in hot forming industries such as thermoforming, rough forging, hot stamping, and hot extrusion rolling. It makes full use of many products that are heated to a certain temperature by metal, have plasticity characteristics, and then use various means to roll the metal into a desired shape.

Induction heating furnace is a new technology. When heating, the conductor has a skin effect, ring effect, proximity effect, end effect and other current distribution unevenness. Increased design difficulty. In order to fully utilize the performance of the device, it must be noted in engineering design:
Correct selection of power supply current frequency
The frequency for induction heating ranges from a few hertz (Hz) to several tens of megahertz (MHz). Different frequencies are selected according to the process requirements. Generally, the blank with a small diameter has a high selection frequency, and the blank with a large diameter has a low selection frequency. Forging heating is penetration heating.
