장점 고주파 유도 가열기 in the surface quenching of metal workpieces

The surface quenching of metal workpieces by high-frequency induction heating machine is compared with ordinary and traditional heating and quenching methods: flame heating surface quenching, electrical contact heating surface quenching, electrolyte heating surface quenching, laser heating surface quenching, electron beam heating surface quenching, etc. Below, the summary has the following advantages:

1. The heating speed is extremely fast, which can expand the transformation temperature range of the workpiece A and shorten the transformation time.

2. After quenching, the surface layer of the workpiece can get extremely fine cryptocrystalline martensite, and the hardness is slightly higher (2-3HRC). Professional high frequency heating machine with low brittleness and high fatigue strength.

3. 이 공정으로 처리된 가공물은 산화 및 탈탄이 용이하지 않으며 일부 가공물도 직접 조립하여 처리 후 사용할 수 있다.

1. The hardened layer is deep, easy to control and operate, easy to realize mechanization and automation.
