Viscosity calculation for the SiO2CaO-FeO-V2O3−MnO-TiO2 system based on a statistical modeling approach
Source abstract
Abstract
An accurate and simple viscosity model based on the physically meaningful MYEGA equation has been established for the SiO 2 _{}CaO-FeO-V 2O 3 −MnO-TiO 2 system. The present model accurately predicts the viscosity with an average error (Δ) of 18.76% and root mean square error (RMSE) of 0.108 Pa•s. The composition and temperature dependences of viscosity were discussed. The results show that the vanadium spinel would be precipitated from liquid slag when the viscosity curve enters into the crystalline region. With increasing CaO/SiO 2 and FeO/SiO 2 mass ratio, the viscosity of molten slag firstly decreases remarkably, subsequently followed by a slight decrease and tended to be stable, implying that FeO and CaO behave similarly in viscous flow. V 2O 3 behaves as a network former in the network structure and would obviously increase the viscosity. The viscosity generally increases at low SiO 2 region and decreases at high SiO 2 region with increasing TiO 2 content, indicating the amphoteric behavior of TiO 2.
