摘要：

The viscosity of the CaO-Al2O3-MgO slag system has been measured by the rotating cylinder method up to 1823 K. The MgO content was between 0.39 and 11.33 wt-%, and the mass ratio of CaO/Al2O3 was between 0.60 and 1.28. The results indicated that both the MgO content and the mass ratio of CaO/Al2O3 have an influence on the viscosity of the slag. The effect of the mass ratio of CaO/Al2O3 is larger than that of the MgO content. The viscosity decreased with increasing MgO content and then increased. The effect of the mass ratio of CaO/Al2O3 on the viscosity was similar. The main mineralogical compositions of the slag were determined by X-ray diffraction, and their effects on viscosity were investigated. The measured results were in good agreement with those given by the Iida model.
