According to the data from official website, Ministry of Industry and Information Technology of China, high-frequency induction heating equipment is mainly used in the fields of metal heat treatment, quenching, diathermy, melting, brazing, degassing heating of electric vacuum devices, semiconductor material refining, plastic packaging, baking and purification. The frequency of use is usually above 40kHz and below 200kHz.
The frequency of induction heating equipment is related to parameters such as heating layer depth and heating efficiency. At the same time, the nature and shape of the heating material, the temperature and dielectric constant of the surrounding environment will also affect the effect of high frequency induction heating. In medical, food, chemical and other fields, high-frequency induction technology can realize many functions such as heating, drying, sealing and curing, and has broad application prospects.
