The Relationship between Viscosity and Electrical Conductivity of CaF_2-SiO_2-Al_2O_3-CaO-MgO Slag System

摘要

The relationship between the viscosity and the electrical conductivity of CaF_2-SiO_2-Al_2O_3-CaO-MgO slag system was deduced through theoretical calculation and experiment. The experiment was designed by quadratic orthogonal rotary regression method. The slag viscosity and conductivity were measured at 1600°C, and the constant (C) was calculated. The calculating model between each component mass fraction and constant C was performed, and the stability of calculating model was also verified by representative slag. The results showed that the calculating constant (C) of regression model is in good agreement with experimental values. Thus, the relationship between refining slag viscosity and conductivity using the formula κη = C at certain temperature is feasible.
