摘要
采用化学分析、金相检验和扫描电镜分析等方法,对CSP热轧薄板边部出现开裂的原因进行了分析。结果表明,CSP薄板坯边部集中分布的大颗粒Al2O3夹杂物是导致板坯在轧制过程中边部发生开裂的主要原因。
The cause for cracking at edge of csp hot-rolled sheet was studied by the methods of chemical analysis, metallographical examination and SEM analysis. The results show that large Al_2O_3 inclusions concentrating on the edge of CSP sheet bar cause the cracking during rolling.
