Surface hardening equipment frequency range is 0.1-20KHZ. It is mainly for standard parts forging, metal melting, motor rotor heating, steel tube end expanding, billet heating, medium frequency hardening, preheating and tempering etc.

induction tempering machine heating time is short, tempering temperature is raised appropriately. The workpiece after surface hardening could choose furnace inside tempering,self-tempering, or induction tempering. Induction tempering is adopts electromagnetic induction method to make the heated workpiece internal produce current.

Induction hardening machine adopts the electromagnetic induction principle, make the parts in the alternating magnetic field cutting magnetic field line, on the surface to produce the current, according to the alternating current skin effect.
