Electric heating is currently the most efficient, fastest, low-consumption, energy-saving and environmentally friendly induction heating equipment for heating metal materials. Electric heating, 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 (welding machine), etc., in addition to intermediate frequency induction heating equipment, ultra-high frequency induction heating equipment, etc. The scope of application is very wide.
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 achieve higher temperature (such as 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 as required . Electric heating can directly generate heat inside the heated object, so it has high thermal efficiency and fast heating speed. According to the heating process requirements, it can realize uniform heating or local heating (including surface heating), and it is easy to realize vacuum heating and controlled atmosphere heating. During the electric heating process, there is less waste gas, residues and smoke, which can keep the heated object clean without polluting the environment. Therefore, electric heating is widely used in fields such as production, scientific research and testing. Especially in the manufacturing of single crystals and transistors, mechanical parts and surface quenching, smelting of ferroalloys, and manufacturing of artificial graphite, electric heating methods are used.
