Abstract

The effects of MgO, TiO2or Fe2O3on the viscosity of 40CaO-40SiO2-20Al2O3/mass% slags have been measured by a rotating crucible viscometer. The viscosity of these quaternary slags decreased with increasing the content of additive oxide. At the same content of additive oxide, the viscosity decreases from MgO, TiO2to Fe2O3. In addition, the effects of SiO2, AI2O3or MgO on the viscosity of 26.1CaO-73.9Fe2O3/ mass% (CP) and 14.9CaO-85.1Fe2O3/ mass% (CF2) slags have been measured. Viscosity of calcium ferrite slags increased with increasing SiO2, AI2O3or MgO content. AI2O3was found to be more effective for increasing the viscosity at the same content of additive oxide.
