摘要: 采用熱力學計算軟件FactSage的Phase Diagram模塊和Equilib模塊對含鈦鋼渣熔點進行理論研究,并通過熔點實驗對研究結果進行驗證.研究發現：對于堿度R<1.5的渣系,當TiO₂質量分數小于13%時,TiO₂對熔點影響較小;當TiO₂質量分數大于13%時,TiO₂提高熔點.對于R>1.5的渣系,Al₂O₃質量分數為25%-35%時,TiO₂的質量分數超過1%可顯著提高渣系熔點.

Abstract: The melting point of titanium-containing steel slag was theoretically calculated using the Phase Diagram module and the Equilib module of thermodynamic calculation software FactSage,and the calculation result was verified by melting experiments.It is shown that,for a slag system with the basicity below 1.5,when the mass fraction of TiO₂ is less than 13%,TiO₂ has little effect on the melting point of the slag,and while the mass fraction of TiO₂ is over 13%,TiO₂ can increase the melting point.For a slag system whose basicity is over 1.5 and mass fraction of Al₂O₃ is between 25% and 35%,when the mass fraction of TiO₂ is more than 1%,TiO₂ can significantly increase the melting point of the slag.
