High-frequency high-current flows to the heating coil that is wound into a ring or other shape (usually made of the copper tube). As a result, a strong magnetic beam with an instantaneous polarity change is generated in the coil. When a heated substance such as metal is placed in the coil, the magnetic beam will penetrate the entire heated substance, and a large vortex is generated inside the heated substance in the direction opposite to the heating current. The current, due to the Joule heat generated by the resistance in the heated substance, causes the temperature of the substance to rise rapidly. This is the principle of induction heating.
The high-frequency induction heater is equipped with alarm devices such as over-current, over-pressure, over-heat, and water shortage, which makes the equipment have a self-protection function and greatly improves the service life of the equipment. When the dive steel is diathermy heat-treated, the heating speed is very fast. Such a fast heating speed effectively avoids the oxidation and decarbonization of the square steel during the heating process and ensures the heating effect of the square steel. It can not only heat the other party’s steel as a whole but also heat the other party’s steel locally to meet the requirements of different customers.
The induction coil of the high-frequency induction heater can be replaced freely, which allows the equipment to complete the heat treatment processes such as quenching, annealing, tempering, normalizing, and tempering, as well as welding, melting, hot assembly, hot disassembly, and diathermy Waiting for the work, truly realized the multi-purpose equipment.
In addition to the above applications, the high-frequency induction heater is mainly environmentally friendly. For environmental protection, it supports the development of environmental protection equipment in the industry, so the environmental protection characteristics of the high-frequency heater are worthy of attention. It is also an environmentally friendly product supported by the family. High-frequency induction heating The appearance of the machine has replaced the traditional pollution source (the traditional heating method uses coal or gas). The traditional heating method will more or less pollute the atmosphere. This time, with the advent of high-frequency induction heaters, environmental protection is worthy of recognition.
