摘要： 单纯的实验测定已无法满足对熔渣黏度数据的实际需求,利用D.Sichen和S.Seetharaman等人的黏度模型和熔渣的正规溶液(RS)模型理论,建立了熔渣组元吉布斯黏流活化能、吉布斯混合自由能以及组成与熔渣黏度的函数关系,即熔渣黏度估算模型.并估算、测量了CaF2-CaO,Al2O3-CaO两个体系渣样的黏度.结果表明:对于CaF2-CaO渣系,黏度测量值与修正模型估算值吻合很好;对于Al2O3-CaO渣系,模型估算值与黏度测量值基本吻合,但在共晶点组成渣样的模型估算值与实际测量值吻合得更好.

Abstract: Mere measurements can not meet the actual requirements for determining the slag viscosities. Based on the viscosity model and regular solution model for slag proposed by D Sichen and S Seetharaman, the functional relationship between the slag viscosity and composition and the Gibbs viscous activation energy and mixture free energy of slag components was derived, i.e., the viscosity estimation model. Then, the viscosities of both CaF2-CaO and Al2O3-CaO slag system samples were estimated and measured. The results indicated that, the estimated viscosities modified by the model and the measured ones coincide well for CaF2-Ca O slag system. As for the Al2O3-CaO slag system, the estimated viscosities conform basically with the measured ones but both coincide better in the vicinity of compositional eutectic point.
