摘 要:通过建立二次回归正交设计模型,考察了合成精炼渣碱度伽(CaO)/w(SiO2),Al2O3和CRF2质量分数对LF深脱硫效果的影响.结果表明,当渣中w(FeO)为0.5%,w(MgO)为9%时,随渣中w(CaO)/w(SiO2)增加,脱硫率均先增大后减小.当伽(CaO)/w(SiO2)不同时,Al2O3和C&F2质量分数对脱硫效果的影响程度不同,主要原因是渣中有效CaO含量变化引起的.随渣中w(FeO)降低和渣量增加,脱硫率明显增大.实验优化的最佳脱硫渣系组成为w(CaO)/w(Si02)=9-11,w(Al2O3)=27%~29%,w(MgO)=9%,w(CaF2)=8%~10%,w(FeO)小于0.5%.A model of quadratic orthogonal regression design was designed to investigate the influences of w (CaO)/w (SiO2) and mass fraction of Al2O3. and CaF2 in refining slag on the desulphurization in LF. The results showed that, in the slag if FeO and MgO contents are 0.5% and 9%, respectively, the desulphurization rate increases then decreases with the increasing w (CaO)/w (SiO2) value whose change will affect the influence of Al2O3, CaF2 content on the desulphurization rate. The main reason is the change in the useful CaO content in refining slag. In addition, the desulphurization rate increases obviously with increasing slag volume and decreasing FeO content. In the experiment the optimum slag composition was found to be w(CaO)/ w(SiO2):9~11, w(Al2O3): 27%~29%, w(MgO): 9%, w(CaF2): 8%--10% and w(FeO): less than0.5%.
