induction hardening equipment classification

induction hardening equipment types are divided into: frequency, low frequency, medium frequency, super audio,induction heating equipment HF, UHF several, according to the hardening depth need to select the appropriate frequency. The greater the depth of hardened layer, the lower the required frequency, and vice versa, is higher.
Currently induction hardening to IF, super audio, HF, UHF-based.
IF generally SCR, IGBT induction power to do useful intermediate frequency than the SCR energy saving,induction heating equipment but the price is higher than the SCR. Relatively speaking, IGBT is the development trend, because of its high conversion efficiency, and stable performance, internal soft-switch, not prone to failure.
