The use principle and advantages of high frequency furnace

High-frequency furnace is currently an induction heating equipment with higher heating efficiency, faster speed, low consumption, energy saving and environmental protection for metal materials.

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 high current flows to the heating coil (usually made of copper tube) that is wound into a ring or other shape. 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, and in the opposite direction of the heating current inside the heated object, it will generate 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.

The use of high frequency equipment:

1. Heat treatment: local or overall quenching, annealing, tempering, and diathermy of various metals;

2. Hot forming: whole piece forging, partial forging, hot upsetting, hot rolling;

3. Welding: brazing of various metal products, welding of various tool blades, saw blades, welding of steel pipes, copper pipes, welding of the same and dissimilar metals;

4. Metal smelting: (vacuum) smelting, casting and evaporative coating of gold, silver, copper, iron, aluminum and other metals;

5. Other applications of high frequency heating machine: semiconductor single crystal growth, heat fitting, bottle mouth heat sealing, toothpaste skin heat sealing, powder coating, metal implantation plastic, etc.
