摘要
为确定Ca O-Al2O3-Si O2-Ti O2渣系的脱硫能力,使用10 kg感应炉进行脱硫试验并结合Factsage热力学软件理论计算,考察了二元碱度,Al2O3和Ti O2含量对该渣系脱硫能力的影响。结果表明:二元碱度对渣系硫分配系数的影响显著,其他因素的影响不显著;试验条件下渣系最高硫分配系数的最优组合为:二元碱度7,Al2O330%和Ti O23%,试验条件下的最佳硫分配系数58.14;Ti O2含量低于3%时,Ca O-Al2O3-Si O2-Ti O2脱硫能力和Ca O-Al2O3-Si O2渣系接近,能够满足炼钢脱硫要求。
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.
