What Is Induction Quenching? What Are The Characteristics?

  Induction quenching, or induction heating, is the use of electromagnetic induction in the workpiece to generate eddy currents and the workpiece to be heated. Induction heating surface quenching and ordinary quenching ratio have the following advantages:

1. The heat source is on the surface of the workpiece, with fast heating speed and high thermal efficiency

2. Because the workpiece is not heated as a whole, the deformation is small

3. The heating time of the workpiece is short, and the amount of surface oxidation and decarburization is small

4. The workpiece surface hardness is high, notch sensitivity is small, impact toughness, fatigue strength, and wear resistance are greatly improved. It is beneficial to give play to the potential of materials, save material consumption and improve the service life of parts

5. Compact equipment, easy to use, good working conditions

6. Facilitate mechanization and automation

7. Not only for surface quenching but also for penetration heating and chemical heat treatment, etc.
