	<span style=\"line-height:1.5;\">本文以CaO-Al<sub>2</sub>O<sub>3</sub>-SiO<sub>2</sub>-MgO-CaF<sub>2</sub>基础精炼渣系，通过加入铝矾土等量取代CaF<sub>2</sub>，研究铝矾土替代萤石对精炼脱硫效果的影响。实验结果表明：铝矾土替代萤石造渣对钢液脱硫有良好的效果，碱度的增加和适量的铝矾土加入量，能够提高精炼渣的脱硫率，当CaO/SiO<sub>2</sub>的比值在11~12，铝矾土的含量在4%~5%时，脱硫效果最佳，可达到80%以上；实验渣对钢中夹杂物的改性和去除也有良好的效果。&lt;br/&gt;In the study, the effect of bauxite instead of fluorite acting as flux in CaO-Al<sub>2</sub>O<sub>3</sub>-SiO<sub>2</sub>-MgO refining slag on desulfurization efficiency was researched. The result shows bauxite replacing fluorite im-proves desulphurization efficiency. In a certain range, the addition of bauxite can reduce the con-tent of sulfur in liquid steel. When the CaO/SiO<sub>2</sub> ratio ranges from 11 to 12, and the content of bauxite is 4% - 5%, the desulfurization effect is best and can reach more than 80%. Besides, the slag has better property of modifying and removing inclusions.</span><span style=\"line-height:1.5;\"></span>
