Calculating Models on the Viscosity of MnO-SiO_2, MgO-SiO_2and CaO-Al_2O_3-SiO_2, Slag Systems

According to the coexistence theory of slag strUctUre as well as the measured viscosity ofMnO-SiO,,MgO-SiO, and CaO-A12O3-SiOZ slag systems at differeflt tCmperthees and slag compositions, calculating models of viscosity for these slag systems have been formulated.CalculatCd results agree well withmeasured results, showing that these models can correctly illustrate the relationships of viscosity with temperatUres and the ma$s action concentrations of the structural units of these slag systems.
