Abstract

Using the method of simplex lattices for experiment planning, the viscosity of slags of the CaO-SiO2-Cr2O3-3%Al2O3-8%MgO-6%B2O3 system was studied in a wide range of chemical composition. For each viscosity value, adequate mathematical models are obtained in the form of a reduced III degree polynomial. The results of mathematical modeling are presented graphically in the form of composition-viscosity diagrams. The range of compositions of the studied slags with a basicity of 1.5-2.0 has a high liquid mobility in the temperature range of 1600 -1700°C and their viscosity does not exceed 0.3 Pa·s.
