摘要： 用已建立的针对非二氧化硅体系的粘度模型对CaO Al2O3体系的粘度值进行估算,与前人的测量值进行了比较,估算值和文献测量值吻合·根据已知文献确定了CaO Al2O3体系中的Al3+和Ca2+的离子作用系数L·由测量知,CaO Al2O3体系共晶点附近的熔渣流动性好,在1460℃时粘度值低于0 5Pa·s·对于Al2O3 CaO MgO体系按两个不同共晶点处的成分配渣,其中含氧化钙较多的渣粘度较低,1500℃时,其粘度小于0 03Pa·s·添加剂MgO能显著降低CaO Al2O3体系的熔渣粘度·

Abstract: The viscosity model, which has already been built to apply as a reference to the slag systems without SiO2, was used to estimate the viscosities of Al2O3-CaO system. The results showed that the estimated values conform well with the measured values as shown in some known literatures. The ionization factor, L, between A13+ and Ca2+ in the Al2O3-CaO system was determined from the experimental data as shown in known literatures. According to the measurements, the slags have good fluidities around the eutectic point and the viscosities are below 0.5 Pa·s at 1460°C for Al2O3-CaO system. As to Al2O3-CaO-MgO system, the slags were prepared according to compositions of two different eutectic points, and the viscosity of the slag which contains more CaO is lower, ie. lower than 0.03 Pa·s at 1500°C. In addition, the additive MgO can reduce obviously the slag viscosity values of Al2O3-CaO system.
