Working principle and principle of electric heating ring

Date of issue: 2020-04-20 Author: Shanghai xionglei Environmental Protection Technology Co., Ltd Click:

High frequency and high current flow to a heating coil (usually made of copper tube) which is wound into a ring or other shape. As a result, a strong magnetic beam with instantaneous polarity change is generated in the coil. When the metal and other heated objects are placed in the coil, the magnetic beam will pass through the whole heated object. In the direction opposite to the heating current in the heated object, a corresponding large eddy current will be generated. Because there is resistance in the heated object, it will produce a lot of Joule heat, which makes the temperature of the object rise rapidly. To achieve the purpose of heating all metal materials.

Electric heating ring Application of

1、 Heat treatment: annealing, tempering, diathermy;

2、 Hot forming: whole piece forging, local forging, hot heading and hot rolling;

3、 Welding: brazing of various metal products, local or whole quenching of various kinds of cutting tools and blades, welding of saw blade saw teeth, welding of steel pipe and copper pipe, welding of the same and different metals;

4、 Metal smelting: vacuum melting, casting and evaporation coating of gold, silver, copper, iron, aluminum and other metals;

5、 Other applications of high frequency heater: semiconductor single crystal growth, thermal matching, bottle mouth heat sealing, toothpaste skin heat sealing, powder coating, metal implanted plastic.
