The advantages of high frequency induction heating machine 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. The workpieces treated by this process are not easy to be oxidized and decarburized, and even some workpieces can be directly assembled and used after treatment.

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