用旋转圆柱法测定了CaO-Al_2O_3-MgO渣系在1823K以下的粘度，其中MgO含量为0.39~11.33wt-%，CaO/Al_2O_3质量比为0.60~1.28。结果表明，镁含量和CaO/Al_2O_3质量比对渣的粘度均有影响。CaO/Al_2O_3质量比的影响大于MgO含量的影响。粘度随氧化镁含量的增加先降低后升高。CaO/Al_2O_3质量比对粘度的影响相似。用X射线衍射仪测定了炉渣的主要矿物组成，并考察了它们对粘度的影响。测量结果与Iida模型给出的结果吻合较好。
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.
