摘　　要：结合LF炉铝基还原剂的使用实际,分析了利用铝基还原剂造渣的原理,通过优化铝基还原剂的使用方法,使得LF炉终渣氧化性和终点钢水氧位下降,脱硫稳定性和终点脱硫率也有所提高,改善了钢水的洁净度和可浇性,有效的降低了LF炉渣料消耗和精炼成本。Combined with the actual use of aluminum-based reducing agent in LF furnace,the principle of slag making by aluminum-based reducing agent is analyzed.By optimizing the use method of aluminum-based reducing a-gent,the oxidation of LF slag and the oxygen potential of molten steel at the end point are decreased,the desulfu-rization stability and the end point desulfurization rate are also improved,the cleanliness and castability of molten steel are improved,and the consumption of LF slag and refining cost are effectively reduced.

关 键 词：铝基还原剂 LF炉精炼 脱硫率
