1. Application Ranges of induction hardening machine.
Induction heating power technology currently has the highest heating efficiency, fastest speed for metal materials, and low consumption and environmental protection. It has been widely used in hot processing, heat treatment, hot assembly and welding, smelting and other processes of metal materials in all walks of life. It can not only heat the workpiece as a whole, but also heat the workpiece locally; it can achieve deep heat penetration of the workpiece, and it can only heat the surface and surface of the workpiece; it can not only directly heat metal materials, but also non-metallic materials. Indirect heating of materials, etc. Therefore, induction heating technology will be more and more widely used.
Fundamental:
Put the workpiece into the inductor (coil), when an alternating current of a certain frequency is passed into the inductor, an alternating magnetic field is generated around it. The electromagnetic induction of the alternating magnetic field produces a closed induced current in the workpiece—eddy current. The distribution of the induced current on the cross section of the workpiece is very uneven, and the current density on the surface of the workpiece is very high and gradually decreases inward. This phenomenon is called the skin effect. The electric energy of the high-density current on the surface of the workpiece is converted into heat energy, which increases the temperature of the surface layer, that is, surface heating is realized. The higher the current frequency, the greater the current density difference between the surface layer and the inside of the workpiece, and the thinner the heating layer. Surface quenching can be achieved by rapid cooling after the temperature of the heating layer exceeds the critical point temperature of the steel.

3. Induction Quenching Hardening Machine Application:
(1) For auto parts and motorcycle parts hardening.
(2) For machinery parts, like gears, transmission wheels, axles, shafts, spline shafts, ball stud hardening.
(3) For machine tools quenching, like guide rail machine tools hardening.
(4) For spanner, pliers, CNC machines, hammer, axe hardening etc.

In the manufacture and production of mechanical equipment such as automobiles and machine tools, there are many workpieces of transmission mechanisms that need to bear large loads and frequent start and stop, so the surface needs to have high hardness, strength and wear resistance. Better toughness is required. For example: gears, camshafts, valve rods, forward rods, automobile half shafts, spline shafts, sprockets, optical shafts, guide rails, profiling parts, etc. Therefore, it is necessary to perform surface heat treatment on these workpieces. The traditional surface heat treatment includes: surface carburizing, nitriding; carbonitriding; surface quenching, etc. Compared with other heat treatment processes, surface quenching has lower cost, higher efficiency and more It is small, the operation is simpler, the advantages are very obvious, and it is widely used in industrial production.
