炉渣成分对钒钛磁铁矿高炉渣系冶金性能的影响

he components of practical BF slag of vanadium-titanium magnetite provided by a domestic enterprise were adjusted by adding pure chemical reagents in this study, then the effects of binary basicity R2, MgO content, Al2O3 content, TiO2 content and V2O5 content on the metallurgical properties of BF slag of vanadium-titanium magnetite were studied systematically . The experimental results were as follows: with the R2 and MgO content increasing, the melting temperature(Tm), initial viscosity(η0) and high-temperature viscosity(ηh) of slag were in the first decreased and then increased trend; with the Al2O3 content increasing, the Tm of slag was significantly elevated increased, the η0 of slag was in the first decreased and then increased trend, the ηh of slag were increased approximately; with the TiO2 content increasing, the Tm of slag was obviously increased, the η0 and ηh of slag were in the downward trend overall, the viscous flow activation energy of slag wsa increased gradually and the heat endurance of slag became worse; with the V2O5 content increasing, the Tm of slag was first decreased and then increased, the η0 and ηh of slag were in increased trend.
