"High frequency" refers to high frequency induction heating technology, which heats metal materials with the highest efficiency, fastest speed, low consumption and environmental protection. It has been widely used in various industries such as thermal processing, heat treatment, thermal assembly, welding, and smelting of metal materials.
It can not only heat the workpiece as a whole, but also carry out targeted heating on the workpiece; it can realize deep melting of the workpiece, or only heat the surface and surface of the workpiece; it can not only directly heat metal materials, but also directly heat non-metallic materials. Indirect heating of materials. Therefore, induction heating technology will be more and more widely used in all walks of life. Induction heating refers to the process in which a metal is excited by a high-frequency electric field with a frequency of tens of hertz to several megahertz, a current is induced, and heat is generated on the surface or inside of the metal.
High frequency: seamless cutting (induction heating) process has the following characteristics:
① There is no need to heat the entire workpiece, the deformation of the workpiece is small, and the power consumption is small.
②No pollution.
③The heating speed is fast, and the oxidation and decarburization of the workpiece surface is relatively light.
④The surface hardening layer can be adjusted according to the needs, which is easy to control.
⑤ Heating equipment can be installed on the mechanical processing production line, which is easy to realize mechanization, automation, and easy management, which can reduce transportation, save manpower, and improve production efficiency.
⑥ The martensite structure of the hardened layer is finer, and the hardness, strength and toughness are higher.
⑦ After surface quenching, the surface layer of the workpiece has a large compressive internal stress, and the workpiece has a high fatigue resistance.
