の利点 高周波誘導加熱装置 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.このプロセスで処理されたワークピースは、酸化や脱炭が容易ではなく、処理後に直接組み立てて使用できるワークピースもあります。

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