The Purpose Of The Heating Coil

High-frequency high-frequency large current flows to a heating coil (usually made of copper tube) wound into a ring or other shape. As a result, a strong magnetic flux with instantaneous polarity changes is generated in the coil. When a heated object such as a metal is placed in the coil, the magnetic flux will penetrate the entire heated object. In the opposite direction of the heating current inside the heated object, a The corresponding large eddy current. Due to the 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. 1. Heat treatment: partial or overall quenching, annealing, tempering, and diathermy of various metals;
2. Thermoforming: whole piece forging, partial forging, hot heading, hot rolling;
3. Welding: brazing of various metal products, welding of various knife blades and saw blades, welding of steel pipes and copper pipes, welding of the same and different metals;
4. Metal smelting: (vacuum) smelting, casting molding and evaporation coating of gold, silver, copper, iron, aluminum and other metals;
5. Other applications of high-frequency heating machine: semiconductor single crystal growth, thermal fit, bottle mouth heat sealing, toothpaste skin heat sealing, powder coating, metal implanted plastic
