摘要
阐述了条痕缺陷的特征与形成机理,讨论了产生条痕缺陷影响因素,并介绍采取提高钢水纯净度、稳定结晶器内钢液液面、优化保护渣理化指标等措施取得的效果。1 810线SPHC冷轧板表面缺陷具有条痕缺陷的特征,能谱分析证明缺陷具有保护渣成分,条痕缺陷由保护渣卷入所引起。应从优化保护渣理化指标、稳定结晶器液面等方面开展工作。
It is stated the characteristics and forming mechanism of streak defect, discussed its affecting factors, and introduced the result to adopt the following measures： improving pureness of molten steel, stabilizing molten steel surface in mold, optimizing physical and chemical indexes of protecting slag and so on.
