In order to clarify the slag system of high Cr2O3 vanadium-titanium magnetite smelting in BF (blast furnace), the melting properties of slag samples prepared by analytically pure reagents were measured. By means of orthogonal test synthetic weighted score method, the optimal slag for high Cr2O3 vanadium-titanium magnetite was obtained, which contained 10% MgO, 8% TiO2 and 15% Al2O3, with the binary basicity being 1.15. In addition, the effects of basicity, MgO, TiO2 and Al2O3 on slag melting properties were investigated by single factor test, and the results showed that, with increasing the basicity or TiO2 content, melting temperature (Tm) increased, whereas initial viscosity (η0) and high-temperature viscosity (ηb) decreased. With increasing the MgO content, Tm decreased firstly and then increased. With increasing the Al2O3 content, Tm increased, and η0 and ηh decreased firstly and then increased.
