Abstract研究了TiO2含量、Al2O3含量以及二元碱度(CaO/SiO2)对TiO2-Al2O3-CaO-SiO2低碱度高钛渣黏度的影响.实验采用旋转柱体法在1633~1873 K温度范围内对渣系熔体黏度进行了测量.当TiO2质量分数为23%~43%、Al2O3质量分数为3%~12%和二元碱度为0.3~0.7时,钛渣熔体黏度随TiO2含量和碱度的增加而降低,随Al2O3含量的增加而增加.通过对转底炉-电炉熔分过程渣系脱硫能力计算,得知在低碱度高钛渣中TiO2属于酸性.依据黏度测量数据和对TiO2属性的界定,通过修正Urbain模型建立了低碱度高钛渣的熔体黏度预报模型.模型预测结果误差为11%,证明新模型对于低碱度高钛渣的黏度具有良好的预报效果.
