摘　　要：采用了热力学模型模拟方法,计算模拟了铝铬耐火材料与熔融还原炼铁渣的反应过程。计算结果表明三种耐火材料(10Cr_2O_3-90Al_2O_3,50Cr_2O_3-50Al_2O_3和90Cr_2O_3-10Al_2O_3)与熔渣在1500℃条件下发生反应生成尖晶石相MgCr_2O_4和MgAl_2O_4。反应后熔渣中Al_2O_3和Cr_2O_3含量有所增加,说明在此条件下耐火材料在一定程度上发生了溶解,Al_2O_3和Cr_2O_3因而渗入熔渣。热力学模拟能够预测由于耐火材料的溶解作用使得该熔融还原炼铁渣对铝铬耐火材料的渗透深度更深。Aluminum chrome refractories react with smelting reduction ironmaking slag were calculated by thermodynamic model. The results show that epigenetic spinel phase was producted during slag reacted with three kinds of refractories（ 10Cr_2O_3-90Al_2O_3,50C_r2O_3-50Al_2O_3 and 90Cr_2O_3-10Al_2O_3） at 1500 ℃reaction. After the reaction,Al_2O_3 and Cr_2O_3 content of slag increased,which indicated the refractory material has been dissoluted under these conditions. Thermodynamic simulation can predict that the dissolution of refractory materials. As Al_2O_3 and Cr_2O_3 can been disssoluted by slage,refractory materials were corroded deeper by smelting reduction ironmaking slag.
