The components of practical blast furnace (BF)slag of vanadium-titanium magnetite were adjusted by adding pure chemical reagents.The effects of binary basicity,MgO,Al2 O3 , TiO2 and V2 O5 on the metallurgical properties of experimental slag were studied under neutral atmosphere.The results showed that with increasing content of basicity and MgO,the melting temperature (tm ),initial viscosity (η0 )and high-temperature viscosity (ηh )of slag first decrease and then increase.As increasing Al2 O3 content,tm increases,η0 first decreases and then increases,ηh increases.When increasing TiO2 content,tm increases,η0 and ηh decrease.The viscosity flow activation energy of slag increases and the heat stability of slag becomes worse.With increasing V2 O5 content,tm first decreases and then increases,η0 and ηh increase.The suitable BF slag for smelting vanadium-titanium magnetite is:binary basicity 1.15,MgO 13%,Al2 O3 13%,TiO2 7%,V2 O5 0.30%.
