High frequency heating machine has the full name of "high frequency induction heating machine", also known as high frequency induction heating equipment, high frequency induction heating device, high frequency heating power supply, high frequency power supply, high frequency welding machine, high frequency induction heaters (welders), etc., in addition to medium-frequency induction heating equipment, ultra-high frequency induction heating equipment, with a wide range of applications.
The high frequency high current flows to the heating coil (usually made of red copper tube) that is wound into a ring or other shapes. As a result, a strong magnetic beam with instantaneous change in polarity is generated in the coil, and the heated material such as metal is placed in the coil, the magnetic beam will pass through the whole heated material, and a large eddy current is generated inside the heated material in the opposite direction of the heating current, and Joule heat is generated due to the resistance of the heated material, so that the temperature of the material itself rises rapidly, which is the principle of induction heating.
The high frequency induction heating machine is equipped with alarm devices for over-current, over-voltage, over-heating and water shortage, which makes the equipment have self-protection function and greatly improves the service life of the equipment.
It is very fast in heating the square steel for heat treatment, so fast heating speed effectively avoids oxidation and decarburization of the square steel in the heating process, which ensures the heating effect of the square steel.
What's better is that it can not only heat the whole square steel, but also achieve partial heating of the square steel, which can meet the requirements of different customers.
The induction coil of high frequency induction heating machine can be freely replaced, which makes the equipment can complete the heat treatment process of quenching, annealing, tempering, normalizing, thermal refining, etc., and can also complete the work of welding, melting, hot assembly, hot disassembly and transheat forming, etc., which truly realizes the multi-purpose of the equipment.
In addition to the above applications, high frequency induction heating machine is also very environmentally friendly, the state supports the development of environmental protection equipment in the industry, so the environmental protection characteristics of high frequency heating machine is worth paying attention to, which is supported by the state.
The emergence of high frequency induction heating machine replaces the traditional sources of pollution (traditional heating methods with coal or gas). Conventional heating methods pollute the atmosphere to a greater or lesser extent. With the advent of high frequency induction heating machine, its environmental protection is worthy of affirmation.
