The high-frequency induction furnace has a high melting rate and can maintain power operation at the optimal frequency band during the melting process, greatly eliminating the adverse effects of new lining on the melting speed; High quality molten steel and high yield of castings; High power factor, during the operation of the whole machine, the power factor can reach over 97%, and it will not interfere with the power grid.

High frequency high current flows towards a heating coil that is wound into a ring or other shape (usually made of copper tube). As a result, a strong magnetic beam with instantaneous polarity change is generated within the coil. When a metal or other heated object is placed within the coil, the magnetic beam will penetrate the entire heated object. In the opposite direction of the heating current inside the heated object, a corresponding large eddy current will be generated. Due to the presence of resistance within the heated object, a significant amount of Joule heat is generated, causing the object's temperature to rapidly rise. To achieve the goal of heating all metal materials.
