The desulfurization capability of medium-titanium and low-titanium BF slag in Xuangang was investigated. The results show that basicity,Ti,Mg and Al have important effect on the desulfurization of slag in the CaO-Al2O3-SiO2-MgO-TiO2 slag system. With basicity increasing,desulfurization capability of slag increases. For a certain basicity,increasing the content of TiO2 will bring negative effect on desulfurization. When the basicity of slag is 1.1,the suitable slag composition with near 10.00% of MgO and ~12.00%, of Al2O3 is beneficial to desulfurization. Increasing MgO content and decreasing Al2O3 content appropriately are good for desulfurization as Ti content increases. Controlling the slag parameters reasonably is important for reducing the sulfur content of cast iron and improving desulfurization capability of slag.
