摘　　要：通过对LF炉出站时的渣样取样进行分析,确定新泰钢铁公司炼钢车间现工艺条件下LF炉精炼渣中氧(FeO+MnO)的真实值在1.5%(质量分数)左右。所以生产钢种(ML08Al)的操作工艺规程和转炉、LF炉冶炼操作实绩为依据,通过对炼钢过程的沉淀脱氧材料和扩散脱氧材料进行简要的分析和比较,最终研发出以含Al、CaO以及Al_(2)O_(3)为主的合成渣对精炼渣进行调质处理,实现了LF炉精炼渣中氧化性(FeO+MnO)降低到1.0%(质量分数)以下的理想目标值。By analyzing the slag sample of LF furnace exit,the real value of oxygen content(FeO and MnO)in LF furnace under the current process conditions of Xintai Iron and Steel Company is about 1.5%.Based on the operation process card of the produced steel plant(ML08 Al)and the steel workshop converter process and LF furnace,through the brief analysis and comparison of the precipitation deoxygenation and diffusion deoxygenation,the synthetic slag mainly including Al,CaO and Al_(2)O_(3)developed the ideal target value of oxidoxidation(FeO andMnO)in the LF furnace refining slag below 1.0%.
