| 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 αNb2O5 is in the range of 10-2-10-4. TheδNb2O5 is ranged in 10°-10-2.Niobium partition decreases with the increase of[Si]% and CaO/SiO2. When α[0] and FeO decrease, niobium partition decreases too. TheδNb2o5 and the ratio of siO2 toγNb2O5 decrease with the incre-ase of slag basicity. The suitable thermodynamic conditions in direct alloying of steel with Nb2O5-bearing slag have been found.
