的工作原理 high frequency furnace

High-frequency furnace, also known as high-frequency heating machine, high-frequency induction heating equipment, high-frequency induction heating device, high-frequency heating power supply, high-frequency power supply, high-frequency electric furnace. High-frequency welding machine, high-frequency induction heating machine, high-frequency induction heater (welder), etc., in addition to medium frequency induction heating equipment, ultra-high frequency induction heating equipment, etc. The application range is very wide.

Main working principle: High-frequency high-frequency current flows to the heating coil (usually made of copper tube) that is wound into a ring or other shapes. As a result, a strong magnetic beam with an instantaneous change in polarity is generated in the coil. When a heated object such as a metal is placed in the coil, the magnetic beam will penetrate the entire heated object. Correspondingly large eddy currents. Due to the existence of resistance in the heated object, a lot of Joule heat will be generated, and the temperature of the object itself will rise rapidly. To achieve the purpose of heating all metal materials.
