Viscosity of CaO–CrO_<i>x</i>–SiO₂ slags in a relatively high oxygen partial pressure atmosphere

Abstract

Viscosities of eight CaO–SiO 2 –CrO x slags were measured by the rotating cylinder method up to a temperature of 1750°C. The compositions were selected in the composition range of 38–60 wt% SiO 2 , 53–37 wt% CaO and 0–9 wt% CrO x . The atmosphere was controlled by a CO 2 /CO gas mixture. Iida's viscosity model was applied and good consistency with the measured viscosity values was observed.
