| 摘 要： | 用带钢制成的钢管在压扁试验中出现断裂。采用扫描电镜、能谱和金相分析等方法，对断裂试样进行了夹杂物、晶粒度、显微组织、断口及氧含量的检验和分析。结果表明，钢中夹杂物多和氧含量偏高是导致压扁断裂的主要原因。

| Abstract: | The examination and analysis included microstructure, inclusions, graininess, fracture, oxygen content of unqualified cold bending strip were done by means of XL30SEM, EDA and metallograph analysis and so on. The result shows that the unqualified cause of cold bending strip steel is high oxygen content, high inclusion content, etc. |
