4 Meter Vertical Complete Induction Hardening System For Pin
Induction heating for hardening is one kind of application for induction heating,induction quenching system is common for shaft,pin,gear,brake,wheel,pulley,roller and other auto parts.Because fast heating and energy saving of IGBT induction heating technology,more and more customer choose induction heating as their first choice.
Duolin made complete CNC induction hardening system for customer in South Africa,including 250KW low frequency induction quenching heater,3500Kva transformer,cooling system and 17 set of heating coils with cooling coils to cover pin diameter range 60-200mm,pin maximum length to 4 meter.
After testing in our factory for sample parts,the hardening result reach to 4mm 54HRC,customer satisfied with the result and the complete system working.And they knew that the hardening result can be adjusted by the output power,heating time,cooling time,cooling capacity on CNC program setting.
Any inquiry for metal parts induction surface hardening,contact Duolin freely,our engineer team will offer you free solution and testing to choose the correct induction heating machine power and work frequency.

Induction heating is the process of heating an electrically conducting object (usually a metal) by electromagnetic induction, through heat generated in the object by eddy currents. An induction heater consists of induction power supply (induction heater) and inductor (coil) that is a shaped to contour the part, and a work station where the part is held and presented to the coil.
