The effect of TiO₂ content ranging from 0 wt% to 4 wt% on the viscosity and sulfide capacity of CaO–SiO₂–MgO–Al₂O₃–BaO–TiO₂ slag system was investigated using the rotating spindle method and gas-slag equilibration technique, respectively. The measured sulfide capacity was further compared with the predicted values by some empirical models based on the corrected optical basicity when the effect of charge compensation effect of Ba²⁺ and Ca²⁺ was considered. The results show that the viscosity declines with TiO₂ content increasing while keeping CaO/SiO₂ ratio and other components contents constant, and TiO₂ seems to be more effective in decreasing viscosity when polymerization degree of slag is higher. The sulfide capacity decreases with an increase in TiO₂ content although the dynamic condition is improved due to the viscosity decreasing. The sulfide capacity is enhanced with the increasing corrected optical basicity and it can be predicted by using the modified predicted values based on Zhang’ model.

采用旋转纺锤法和气相法研究了TiO ₂含量在0 wt％至4 wt％范围内对CaO-SiO ₂ -MgO-Al ₂ O ₃ -BaO-TiO ₂渣系统的粘度和硫化能力的影响。炉渣平衡技术。当考虑Ba ²⁺和Ca ²⁺的电荷补偿效应时，基于校正的光学碱度，通过一些经验模型将测得的硫化物容量与预测值进行比较。结果表明，在保持CaO / SiO ₂比及其他组分含量恒定的同时，随着TiO ₂含量的增加，粘度降低。当炉渣的聚合度越高时，似乎₂在降低粘度方面更有效。硫化物容量随TiO ₂含量的增加而降低，尽管由于粘度降低而改善了动态条件。随着校正的光学碱度的增加，硫化物的容量增加，并且可以通过使用基于张氏模型的修正预测值来预测。
