%X 采用金相、电子探针等手段，对Q960E探伤不合的原因进行了分析。结果表明：中心偏析、夹杂物、气体含量高是造成探伤不合的主要原因。通过采取针对性的冶炼及轧制工艺改进措施，将探伤合格率由开发之初的96%提升至目前的99.5%。<br />
The causes of unqualified Q960E flaw detection were analyzed by means of metallography and electron probe. The results show that the center segregation, inclusions and high gas content are the main reasons for unqualified flaw detection. By taking corresponding improvement measures of smelting and rolling process, the qualified rate of flaw detection has been increased from 96% at the beginning of development to 99.5% at present.
