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.
