IGBT 50kw Metal Workpiece gear and shaft Induction Quenching
hardening equipment machine
1. What is induction hardening?
Induction hardening uses induced heat and rapid cooling (quenching)
to increase the hardness and durability of steel. Induction is a
no-contact process that quickly produces intense, localized and
controllable heat. With induction, only the part to be hardened is
heated. Optimizing process parameters such as heating cycles,
frequencies and coil and quench design result in the best possible
outcomes.
