Influence of Al2O3 CaO/SiO2 and B2O3 on Viscous Behavior
Abstract. The effect of Al 2 O 3 CaO/SiO 2 and B 2 O 3 on the viscosity of high alumina and medium titania blast furnace slag was analyzed. An increase in CaO/SiO 2 ratio from 1.14 to 1.44 resulted in higher slag viscosity and break point temperature. They also increased with increasing Al 2 O 3 content but decreased with adding B 2 O 3 and Al 2 O 3 simultaneously at a fixed CaO/SiO 2 ratio
