摘　　要：二连铸板坯表面的主要缺陷是发生在B坯上的夹渣 ,通过现场调查、质量跟踪和缺陷分析 ,发现B坯夹渣缺陷主要集中在开浇 2m长度段内。分析了缺陷产生原因 。The main surface defects of NO.2 CC slab are caused by slag on the B slabs.It is found that most of the defects concentrate within the first two meters of start up of casting,by spot survey,quality track and defect analysis.The cause of defects on B slabs is analyzed and the relative improvement measurements are also put forward in the paper.
