摘　　要：针对唐钢第一钢轧厂3#LF精炼冶炼供1#机SPHC时不能保证恒拉速运行的现状,通过提高铁水预处理脱硫率,降低了LF精炼脱硫负荷;改变转炉炉后预脱氧方式,降低了LF精炼前钢水氧位;优化LF精炼脱氧工艺、供电制度及吹氩制度等,提高了LF精炼效率。实现了1#机的恒拉速,保证了生产的稳定,提高了产品质量。In an aim to address the condition that the constant casting speed could not be ensured when LF 3 supplied SPHC 1 at Tanggang Rolling Mill 1, the authors relieved LF desulfurization burden by increasing hot metal pre-desulfurization rate; lowered steel oxygen content before LF refining by changing pre-deoxidization method after converter; raised LF refining efficiency by optimizing LF deoxidization process, power supply system and argon injection system. Thus, SPHC 1 could keep constant casting speeds and the production stability was ensured with improved product quality.
