| Abstract: | The viscosity of CaO-SiO2-Al2O3 slags with 8% MgO and 4% B2O3 is investigated over a broad range of composition, by means of a simplex-lattice experiment design. For slag of basicity 6–8 in the upper left region of the local simplex, with 15–25% Al2O3, 8% MgO, and 4% B2O3, the viscosity is high: 9.4–26.4 P over the range 1500–1530°C. Displacement of the slags of basicity 5–8 to the lower region of the local simplex ensures high fluidity in the given range of Al2O3 concentration: the viscosity is 1.5–6.1 P over the range 1500–1530°C. |
