摘　　要：研究了临钢转炉→LF→连铸工艺流程中钢中氧含量的变化规律。通过在各工序点取样,氮、氧分析,金相观察和电解提取夹杂物分析等工作,摸清了临钢转炉→LF→连铸工艺流程中各工序钢中氧含量的大致水平,分析了进一步提高钢水质量的主要限制环节,并提出了相应的改进建议。The law of variation of oxygen content in LD→LF→CC process in Linfen Steel Works has been studied. By way of sampling and analyzing the nitrogen and oxygen specimen and by metallographic observation and analysis on the inclusions extracted by electrolysis the general level of the oxygen content in steel in the above-mentioned process has been determined and the major factors affecting further improvement in the hot metal quality found out and recommendations for improvement put forward.
