INDUSTRIAL HEATER    MORE    Industry application and principle of electric heating

Electric heating is currently the most efficient, fastest, low-energy, energy-saving and environmentally friendly induction heating equipment for heating metal materials. Electric heating is also called 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 machines, high-frequency induction heating machines, high-frequency induction heaters (welding machines), etc., except for medium-frequency induction heating equipment, ultra-high-frequency induction heating equipment, etc., have a wide range of applications.


Convert electrical energy into thermal energy to heat objects. It is a form of electric energy utilization. Compared with general fuel heating, electric heating can reach a higher temperature (for example, arc heating, the temperature can reach 3000 ℃ or more), easy to realize automatic temperature control and remote control, and can maintain a certain temperature distribution of the heated object. Required. Electric heating can directly generate heat inside the heated object, so it has higher thermal efficiency and faster heating speed.


According to the heating process requirements, uniform heating or local heating (including surface heating) can be realized, and it is easy to realize vacuum heating and controllable atmosphere heating. In the electric heating process, exhaust gas, residue and smoke are reduced, and the heated object can be kept clean without polluting the environment.


Therefore, electric heating is widely used in fields such as production, scientific research and testing. Especially in the manufacture of single crystals and transistors, mechanical parts and surface quenching, smelting of ferroalloys, and the manufacture of artificial graphite, electric heating methods are used.
