Influence of Basicity and MgO on Fluidity and Desulfurization Ability of High Aluminum Slag

Influence of Basicity and MgO on Fluidity and Desulfurization Ability of High Aluminum Slag

The viscosity of experimental slag, which was mixed based on the composition of a practical blast furnace slag, was measured in this paper. The influence of Al2O3 and MgO content, basicity R2 = w(CaO)/w(SiO2) on the fluidity of slag was studied. The stepwise regression analysis in SPSS was used to r...
