| 中文摘要: |
| 目的 研究严重影响磷化板表面质量的冷轧基板表面黑变缺陷的成因及机理。 方法 通过金相分析、扫描电镜电子探针、X 射线光电子能谱法、辉光放电光谱法、X 射线衍射等分析方法,对黑变缺陷进行系统的分析,并对其形成机理进行探讨。 结果 黑变缺陷样板表面 C 元素含量约为正常样板的 17倍,C 元素主要以石墨形式存在。 结论 由于带钢表层富集大量以石墨形式存在的 C 元素,诱发了钢板表面黑变缺陷,其形成原因与钢板化学成分、表面状态以及退火等工艺密切相关。 |

| Objective To study the causes and mechanism of blackening defect seriously affecting the phosphating quality of cold-rolled steel sheet. Methods Blackening defect was systematically analyzed by methods of metalloscope, EDS, XPS, GDS, XRD, etc. , and the formation mechanism was discussed. Results The C element content of the surface of defect steel sheet was nearly 17 times that of normal steel sheet. The C element of the surface of defect steel sheet mainly existed in the form of graphite. Conclusion Blackening defect was caused by massive accumulation of C element in the form of graphite on the surface layer of steel strip, which was closely related with the chemical composition, surface status, and production process such as annealing of the steel sheet. |
