摘要
采用低倍检测、金相检测、扫描电镜及能谱仪等检测方法对某钢厂Q345D钢板探伤缺陷进行分析。结果表明中心成分偏析、夹杂物、异常组织和裂纹是容易造成钢板探伤不合格的原因。
The defect of Q345D steel plate of a steel enterprise was analyzed by the testing methods in macroscopic test, metallographic examination, SEM and EDS etc. The results show that center component segregation, inclusions, ab- normal structure and the flaw are reasons of causing detection disqualification of steel plate readily.
