The uru nke elu ugboro itinye n’ọkwa kpo oku igwe 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 mesoo usoro a adịghị mfe oxidized na decarburized, na ọbụna ụfọdụ workpieces nwere ike kpọmkwem gbakọtara na-eji mgbe ọgwụgwọ.

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