Abstract
The viscosity of molten SiO2-CaO-MgO-Al2O 3 slag was measured using a rotating cylinder method at high CaO and Al2O3 concentration regions to search for a slag with low melting temperature and low viscosity. The experimental results showed that the viscosity of molten 35mass%Al2O 3-43.1mass%CaO-75mass%MgO-14.4mass%SiO2 slag at 1 673 K was lower than 0.6Pa · S that satisfies the fluidity in blast furnace operation. The experimental results were compared with the calculated results of the viscosity model derived by the authors. The viscosity of molten SiO 2-CaO-MgO-Al2O3 system can be evaluated from our model in wide Al2O3 concentration range.
