Influence of Al2O3, CaO/SiO2, and B2O3 on Viscous Behavior of High Alumina and Medium Titania Blast Furnace Slag

The effect of Al2O3, CaO/SiO2, and B2O3 on the viscosity of high alumina and medium titania blast furnace slag was analyzed. An increase in CaO/SiO2 ratio from 1.14 to 1.44 resulted in higher slag viscosity and break point temperature. They also increased with increasing Al2O3 content but decreased...

Description
Summary:The effect of Al2O3, CaO/SiO2, and B2O3 on the viscosity of high alumina and medium titania blast furnace slag was analyzed. An increase in CaO/SiO2 ratio from 1.14 to 1.44 resulted in higher slag viscosity and break point temperature. They also increased with increasing Al2O3 content but decreased with adding B2O3 and Al2O3 simultaneously at a fixed CaO/SiO2 ratio of 1.14, which suggested that the effect of B2O3 on viscosity and break point temperature is predominant compared to Al2O3. Apparent activation energies of CaO–SiO2–MgO–Al2O3–TiO2–B2O3 slag were found to be between 74 and 169 kJ/mol.
