Application in the Experimental Data Analysis of the Slag Viscosity with Minitab Software

The single factor variance of viscosity experimental data of blast furnace slag was calculated by Minitab software. The influence of slag basicity and chemical compositions on the slag viscosity was obtained. The results show that there have insignificant effects on the slag viscosity when the slag basicity is over than 1.02, MgO content is less than 11.95% or TiO2 content is less than 12.57%. While the slag basicity can be influenced significantly with the slag basicity less than 1.02, MgO content over than 13.95% and TiO2 content over 13.57%. The Al2O3 content of the slag should be less than 12.75%.
