摘　　要：通过金相观察、大样电解、电子探针和扫描电镜等手段 ,对南钢连铸小方坯中的夹杂物进行研究 ,找出了夹杂物数量、尺寸、组成、分布和类型在连铸不同工序中的变化规律 ,提出了改善小方坯洁净度的建议。By means of metallographic, EPMA and SEM observation and electrolysis, the inclusions in billets produced by Nanjing Steel have been investigated. The variations of content, size, composition, distribution and type of inclusions during casting have been examined. The measures for enhancing the cleanness of billet are proposed.
