Construction of Viscosity Diagrams for Slags Containing Chromium and Boron Oxides by the Simplex Lattice Method

The viscosities of the slags of the CaO–SiO 2 –Cr 2 O 3 –3% Al 2 O 3 –8% MgO–6% B 2 O 3 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...

Zusammenfassung:The viscosities of the slags of the CaO–SiO 2 –Cr 2 O 3 –3% Al 2 O 3 –8% MgO–6% B 2 O 3 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.
