Identification Method of Quenching Crack and Non-Quenching Crack
Quenching crack is a common quenching defect, which is caused by many reasons. Since the defects of heat treatment start from the product design, the work of preventing cracks should start from the product design. It is necessary to correctly select materials, reasonably carry out structural design, put forward appropriate heat treatment technical requirements, properly arrange the process route, select reasonable heating temperature, holding time, heating medium, cooling medium, cooling method and operation mode.

Basic knowledge of normalizing, annealing, quenching and tempering
The normalizing is a process in which the sub-co-analysis steel is heated to Ac3 30~50 ℃, the co-analysis steel is heated to Ac1 30~50 ℃, and the over-co-analysis steel is heated to Accm 30~50 ℃ and then air cooled. The normalizing cooling rate is larger than that of annealing.
