What is Medium-Frequency Induction Hardening?

Medium-frequency induction hardening involves the use of electromagnetic induction to heat the surface of a workpiece. This fast heating is followed by rapid cooling, typically with water or oil, which hardens the surface while still allowing the core of the material to retain its ductility. The medium-frequency range, usually between 1 kHz to 30 kHz, strikes an ideal balance for many applications, producing effective results without the excessive heat that can occur with low-frequency systems.

Advantages of Medium-Frequency Induction Hardening Equipment

Utilizing medium-frequency induction hardening equipment offers multiple benefits:

  • Rapid Heating: The medium frequency provides swift and uniform heating, reducing overall cycle time.
  • Consistent Results: The precise temperature control allows for uniform hardening across different materials, resulting in reliable performance.
  • Energy Efficiency: Compared to conventional heating methods, induction heating is more energy-efficient, lowering operational costs.
  • Minimal Distortion: The method minimizes thermal distortion, preserving the dimensional accuracy of components.
