What Is a Heating Coil?

Electric heating is the induction heating equipment with the highest heating efficiency, fastest speed, low energy consumption and environmental protection. Electric heating, also known as high frequency heater, high frequency induction heating equipment, high frequency induction heating device, high frequency heating power source, high frequency power source, high frequency electric furnace. High-frequency welding machines, high-frequency induction heating machines, high-frequency induction heaters (welders), etc. In addition, there are medium-frequency induction heating equipment, ultra-high-frequency induction heating equipment, etc. The application range is very wide.

Transform electrical energy into thermal energy to heat an object. It is a form of electric energy utilization. Compared with ordinary fuel heating, electric heating can obtain higher temperature (such as

High-frequency high-current large current flows to a heating coil that is wound into a ring or other shape (usually

According to the different ways of electrical energy conversion, electric heating is usually divided into

I. Heat treatment ^[3] : local or overall quenching, annealing, tempering, and heat penetration of various metals;

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

3. Welding: brazing of various metal products, welding of various cutter blades, sawtooth saw blades, welding of steel pipes, copper pipes, welding of dissimilar metals

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

V. Other applications of high-frequency heaters: semiconductor single crystal growth ^[4] , heat fit, bottle neck heat seal, toothpaste skin heat seal, powder coating, metal implanted plastic.
