摘　　要：为降低铁水预处理过程中的脱硫成本,增强脱硫剂的脱硫能力,从理论依据、设计原则、应用条件、经济技术指标等多个方面对镁-钙基复合脱硫剂进行了分析与研究。并指出了镁应与脱氧元素(Al或Si)以合金的形式存在,与氧化钙结合呈熔合状态,从而改变Mg的物性,提高脱硫效率。另外,提供并保证一定的铁水温度是各反应顺利进行的前提,从镁钙基复合脱硫剂的试用效果与经济指标角度论证了该工艺的可行性。In order to reduce the costs in the process of hot metal desulphurization pretreatment and enhance the desulfurization ability, the paper studies the magnesium-calcium-based compound desulfurizer from the view of theoretical basis, design principles, application conditions, economic and technical indicators and other aspects. The results show that the magnesium and deoxidizing elements （Al or Si） should exist in the form of alloy and combine with calcium oxide to be fusion state so as to transform the physical properties of Mg and improve the desulfurization efficiency. In addition, the precondition of smooth reaction is to provide and maintain the hot metal temperature. Finally, it indicates the feasibility of the Mg-Ca-matrix composite desulfurizer based on the perspective of economic indicators and the using effects.
