The Industrial Needs of Dual Frequency Induction Heating
Generally, the heat treatment process in the gear has a gas carburizing method. this method consume large energy. also produce high carbon dioxide. On the other hands, a single frequency induction heating method has process is complex and long heat treatment time. Therefore, in order to improve some heat treatment processing problems and processing time,  has increasing industrial needs of the dual frequency induction heating system that ensure material quality and high productivity.
Dual Frequency Induction Heating System Overview
Intoruce Dual Frequency Induction Heating(Hardening)
It is a type of Induction Heating system. it’s do output a HF and MF from the inveter at the same time.
Especially, it has the effect to surface hardening of power transmission parts such as gears..
Advantage of Dual Freqneucy Induction Hardening Heating technology
ㆍIt is not fixed the electric current depth
ㆍAble to heat treatment about whole surface by Dual Frequeny(MF+HF) Output
ㆍImprove material durability by strengthen material’s wear resistance
ㆍAcquire precise hardening depths of material
ㆍDo not need to move the heated material
Acquire high durability and low deformation heated mateial quality by apply to dual frequency induction heating
The effect of dual frequency induction heating system
The result compare with single frequency and dual frequency induction heating
