In this paper the desulfurization ability of CaO-Al2O3-SiO2-TiO2 slag was studied through the desulfurization experiment by using 10 kg inductive furnace and theoretical calculation by using thermodynamic software Factsage,in order to determine the impact of binary basicity,mass percent of Al2O3 and TiO2 on desulfurization ability. Calculation indicated that binary basicity had a significant effect on suphher distribution coefficient and the effects of other two factors were invisible. Under the experimental conditions,the optimal combination of parameters for gaining the highest sulphur distribution coefficient for the slag were binary basicity of 7,30% Al2O3 and 3% TiO2,the resulting sulphur distribution coefficient was 58.14. While the content of TiO2 was lower than 3%,the desulfurization ability of CaO-Al2O3-SiO2-TiO2 slag was similar to CaO-Al2O3-SiO2 slag,and the slag system could meet the desulfurization requirements of steelmaking slag.
