1.Material factor In induced quenching steel, manganese, chromium, and molybdenum content have the greatest effect on the depth fluctuation of the hardensed layer. If the cutting sensor quenching found that the heating layer is similar, the depth of the hardened layer is large, and the material ...

The quality test of the induction quenching should generally include appearance, hardness, hardened region, seven projects of hardening, metallographic tissue, deformation and cracks. Guangyuan variable frequency induction heating equipment also emphasizes the quality inspection of induction quen...

The gear induction of low-quenching steel is quenched is the former Soviet meritorious scientist invented. As early as the 1960s, it was applied to the automotive rear bridge gear, the tractor final drive gear, etc. In the 1970s, my country also developed 55Ti, 60Ti, 70Ti and other low-quenching ...

As early as 1948, the US General Motor Company applied to the medium frequency as a fundamental wave, but there was no inductive, but there was no available power supply and the appropriate power density, so this method has practical applications. Until 1993, Germany, Norwegian inventions were re...
