摘　　要：通过高温试验考察了固体颗粒对转炉炉渣黏度的影响。高温试验采用Ca2SiO4析晶–熔渣和MgO析晶-熔渣两种体系。试验结果表明:体系的黏度随固相体积分数的升高而显著增加。模型检验结果显示:Roscoe、Ruiz和Zholkov模型预测与试验结果相近(相对误差小于5.4%)。该研究对含固相转炉炉渣黏度的预测有一定的指导意义。The effect of solid particles on BOF slag viscosity was invesigated by high temperature experiment. In high temperature experiment, the crystallization of Ca2SiO4and MgO from liquid slag was adopted. Experimental results indicate the viscosity of two phase fluid increases significantly with volume faction of crystallization. In addition, experimental data were used to examine the applicability of the existing models. Roscoe, Ruiz and Zholkov models can give good predictions for present experiment（relative error is less than 5.4 %）. The work gives a good guidance for the prediction of slag containing solid particles.
