system over a wide range of their chemical compositions are studied using the simplex lattice method of experimental design. For each viscosity, an adequate mathematical model described by a reduced third-degree polynomial is constructed. The results of mathematical modeling are presented graphically in the form of composition–viscosity diagrams. The slags in the composition region with a basicity of 1.5–2.0 are found to have a high fluidity in the temperature range 1600–1700°C: their viscosity does not exceed 0.3 Pa s.
