Electric IGBT Shaft Induction Heating Quenching Machine Equipment Price
1. Application Ranges of induction quenching machine:
Some metal parts will be subjected to loads such as torsion and bending during use. In this case, the surface layer will bear higher stress than the core. When a metal part is subjected to friction, its surface layer will be slowly worn away, so its surface layer must have properties such as high hardness, strong wear resistance, and high fatigue resistance. Its case hardening is to achieve these properties. Because surface quenching has the advantages of small deformation, low loss, energy saving and high efficiency, it is widely used in specific production and processing.
2. working principle of induction quenching/hardening/tempering:
The working principle of induction heating is to put the metal workpiece into the customized intermediate frequency induction heating equipment inductor. When an alternating current passes through the inductor, an alternating magnetic field with the same frequency as the current is generated around the inductor. A powerful vortex is formed. Eddy currents convert electrical energy into heat, and surface quenching of metal parts is easily achieved.

Induction heating is to use electromagnetic induction to generate eddy currents in the workpiece to heat the workpiece. Compared with ordinary quenching, induction heating surface quenching has the following advantages: First, metal parts can be heated locally, without overall heating, with low loss and small deformation; second, the heating speed is fast and the time is naturally short, so the surface is oxidized The carbon content is very low and the quality is high; three, the medium frequency induction heating equipment saves energy, consumes less energy, and greatly saves the production cost; four, no pollution, no open flame, no dust, environmental protection and safety; five, this equipment is automated, CNC operation and control, easy to operate.
After induction heating surface hardening, the performance of metal parts is greatly enhanced. Specifically, first, its surface hardness value will be as high as 2 HRC (Note: Rockwell, the unit of hardness value) than ordinary quenching; secondly, because after induction surface quenching, the martensite grains of the hardened layer are relatively small , Carbide has high dispersion and high hardness, so its wear resistance is obviously much higher than that after ordinary quenching. Next, its fatigue strength is significantly improved. For metal workpieces of the same material, within a certain range, the depth of the hardened layer increases, and the fatigue strength increases. However, when the depth of the hardened layer is too deep, the fatigue resistance will decrease and the brittleness will increase. Therefore, the depth of the hardened layer should be moderate.
