Induction hardening equipment consists of induction power supply, load line, capacitor, transformer, inductor, and machine tool. The quenching family includes horizontal type, vertical type and special machine, and compensated induction power sources with a wide range of output frequency and power.

Features of Induction quenching equipment:

  • The heat source is on the surface of the workpiece, fast heating speed, high thermal efficiency.
  • Because the workpiece is not been integrally heated, deformation is small.
  • The heating time is short, and the amount of decarburization is less.
  • The surface hardness of the workpiece is high, the notch sensitivity is small, and the impact toughness, fatigue strength and wear resistance are greatly improved. It is beneficial to realize the potential of the material, save material consumption, and improve the service life of parts.
  • The equipment structure is compact, easy to use and good in working conditions.
  • It is convenient for mechanization and automation.
  • It can be used not only in surface quenching but also in penetration heating and chemical heat treatment.
  • Induction quenching is not only applied to the surface hardening, but also to the internal hole hardening, which is not achieved by traditional heat treatment.
  • By means of induction heating quenching, ordinary carbon structural steel can be used instead of alloy structural steel and carburizing steel to make fittings without reducing the quality of parts. Therefore, under certain conditions, chemical heat treatment with a complex process can be replaced.
