Equilibrium between Slag and Molten Iron in the Direct Alloying of Steel with Nb₂O₅-Bearing Slag

Dept. of Metallurgy

摘要: Equilibrium between slag and molten iron at 1600℃ was investigated for the direct alloying of steel with Nb₂O₆-bearing slag. The activity of niobium oxide in the slag was measured. The α_Nb₂O₅ is in the range of 10^-2-10^-4. Theδ_Nb₂O₅ is ranged in 10⁰-10^-2.Niobium partition decreases with the increase of[Si]% and CaO/SiO₂. When α_[0] and ΣFeO decrease, niobium partition decreases too. The δ_Nb₂o₅ and the ratio of γ_siO₂ to γ_Nb₂O₅ decrease with the incre-ase of slag basicity. The suitable thermodynamic conditions in direct alloying of steel with Nb2O5-bearing slag have been found.
