| 摘 要： | 分析了板材边裂的形貌及其金相组织,认为连铸坯角部横裂纹是形成板材边裂缺陷的主要原因。在此基础上,提出了改进铸坯角部横裂纹的有效措施,即控制钢中N、S和P等有害元素含量,优化二冷配水,有效控制了铸坯角部横裂纹缺陷,板材边裂比例由2010年的1.25%降至2011年的0.80%。

| Abstract: | It is introduced the appearance of edge crack on sheet and its metallographic structure,considered it is caused mainly by the transverse crack at the corner of continuous casting billet.Some measures are proposed out to control it： control the harmful elements such as N,S and P,optimizing secondary cooling water.And so the edge crack ratio reduced from 1.25% in 2010 to 0.80% in 2011. |
