摘要

摘要: 采用熱力學軟件FactSage中的Equilib和Phase Diagram模塊分別對Al₂O₃-CaO-MgO三元渣系的熔化性能及添加助熔劑后對渣系熔點的影響進行理論分析，并實驗測定渣系的實際熔點.發現渣系熔點隨w（Al₂O₃）/w（CaO）比的升高先降低后升高，w（MgO）為4%～5%時渣系熔點最低.對于w（Al₂O₃）/w（MgO）>3的渣系，w（CaO）<30%時渣系熔點隨w（CaO）增加而降低.2<w（Al₂O₃）/w（CaO）<2.5，w（MgO）為15%～18%時，釩鐵渣中加2.29%AlCl₃、4.86% Fe₂O₃或4.77% Na₂O時均可降低原渣熔化性溫度約100℃.

Abstract: The melting performance of an Al₂O₃-CaO-MgO ternary slag system and the effect of added fluxes on the melting point of the slag system were theoretically analyzed by using Equilib and Phase Diagram modules in thermodynamic software FactSage. The melting temperature of the slag system from production was measured. It is found that the melting point of the slag system decreases first and then increases with increasing w(Al₂O₃)/w(CaO) ratio, and it reaches the lowest value when w(MgO) is 4% to 5%. At the w (Al₂O₃)/w(MgO) ratio more than 3 and w(CaO) less than 30%, the melting point decreases with increasing w(CaO). When 2〈w (Al₂O₃)/w(CaO) 〈2.5 and w(MgO) is 15% to 18%, the melting point can decrease about 100℃ with the addition of 2.29% AlCl₃, 4.86% Fe₂O₃ or 4.77% Na₂O in the slag system.
