摘　　要：采用FACTSAGE软件对某厂现有LF工序渣料熔点进行分析,表明炉渣组分处于1600℃以上高熔点区域,提出调整钢包渣成分、降低渣系熔点的技术方案,调整后LF精炼炉渣组成为w(CaO)=50%~55%、w(Al_(2)O_(3))=10%~15%、w(SiO_(2))=18%~22%、w(MgO)=7%~9%,渣系熔点降低,炉渣的流动性得到改善,使用效果及各项指标优于现有渣系,且取消萤石的使用,具有明显的社会经济效益。Using FACTSAGE software to analyze the slag melting point of the existing LF process in a factory,it is shown that the slag composition is in the high melting point area above1600℃,and the technical scheme of adjusting the ladle slag composition and reducing the melting point of the slag system is proposed.After adjustment,the LF refining slag composition is w(CaO)=50%~55%,w(Al_(2)O_(3))=10%~15%,w(SiO_(2))=18%~22%,w(MgO)=7%~9%,the slag melting point is reduced,and the fluidity of the slag is improved.The use effect is better than the existing slag system,and the use of fluorite is canceled,which has obvious social and economic benefits.
