Reasons for cracks are usually as follows:

1. Cooling process is too fast;

2. Section areas of steel casting parts change too suddenly, or round corners in transition part are too small;

3. The tress relief annealing was not carried out in time after cooling process;

4. Surface or internal defects.

 

Then let's summarize some methods to prevent the thermal cracking of steel casting parts:

 

1. Improve the structure of steel casting parts.

2. Improve the melting qulity of alloy material

3. Optimize the casting process

4. Aging heat treatment
