线材产品常见质量问题分析及控制
|
摘要
针对天钢集团的线材产品发生的非金属夹杂物导致拉伸断裂、表面缺陷导致断裂、心部成分偏析导致断裂、轧制工艺导致异常组织、连铸坯缺陷导致失效等内在和表面质量问题,进行了横向比较剖析,总结出问题根源,解决了质量问题。
Crosswise comparison and analysis were made on problems of internal and surface quality such as drawing breakage caused by nonmetallic inclusion,breakage by surface defect,breakage by central segregation,abnormal structure by improper rolling process,failure by billet defect and so forth.The root of the problems was summarized and quality problems were solved.
