Abstract
The effect of MgO, TiO2, or Fe2O3 on the viscosity of 40CaO-40SiO2-20Al2O3 (mass pct) slags has been measured by the rotating crucible viscometer. Viscosity of these quaternary slags decreased with an increase in the content of additive oxide. At the same content of additive oxide, the viscosity decreases from MgO, TiO2 to Fe2O3. In addition, the effect of SiO2 or Al2O3 on the viscosity of 26.1CaO-73.9Fe2O3 (mass pct) (CF) and 14.9CaO-85.1Fe2O3 (mass pct) (CF2) slags has been measured. Viscosity of calcium ferrite slags increased with increasing SiO2 or Al2O3 content. Al2O3 was found to be more effective for increasing the viscosity at the same content of the additive oxide.
