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 crank neck induced quenching has the following four quenching processes: 1. The crankshaft is not rotated, and the opening and joint sensor is used to heat on the journal to be heated, and the spray is quenched. Later, a semi-automatic crankshaft quenching machine was developed, and a large ...

The depth of the hardening layer is generally determined according to the working conditions of the quenching. In terms of induction quenching parts, we should pay more about how to choose the hardensed layer depth.

The induction heat treatment process is very important, so we should pay more attention to the inspection heat treatment process to ensure the process is perfect, reduce the occurrence of errors. 1. The processing quality before the quenching of parts, including parts quenching site and the size...
