| Abstract: | The steel balls cracked during heat treatment.The cracking reason was analysed by macro observation and metallographic observation and scanning electron microscope and energy spectrum analysis.The result shows that steel ball cracking is caused by remaining shrinkage clarity.The defect is formed in the smelting process,and it is metallurgical defects.At the same time,combined with the actual production,the corresponding measures are put forward,thus the quality of products is guaranteed. |

| Keywords: | steel ball cracking remaining shrinkage clarity metallurgical defects measures |
