摘要
统计了唐钢第二钢轧厂方坯连铸机2010年漏钢情况,分析了夹渣漏钢、粘结漏钢和角部裂纹漏钢的特点及机理,找出了漏钢产生的主要原因与保护渣的性能、结晶器的精度、钢水过热度、拉速、浸入式水口的对中、操作等因素有关,采取相应的改进措施后,铸机的漏钢率有了明显降低。
Based the statistics of steel leakage in 2010,it is analyzed the features and mechanism of inclusion steel leakage,sticking leakage and corner crack leakage,concluded that is concerned with property of protecting slag,concision of mold,overheating extent of molten steel,drawing speed,center aligning of immersion nozzle and operation.
