Distribution of vanadium between Al₂O₃-CaO-MgO-SiO₂-TiO₂ slag and carbon saturated iron

Abstract

The aim of this study was to determine the behaviour of vanadium in molten slag and carbon saturated iron alloys using a metal-slag-gas equilibration technique under controlled CO atmosphere at temperatures between 1400 and 1500°C. The results obtained show (1) saturation of the metal with vanadium carbide when vanadium content of the metal was greater than 2.4 wt%; (2) Distribution ratio of vanadium between slag and metal to be less than 0.01; (3) the deduced activity coefficient of VO 1.5 decreases with increasing concentration of vanadium in slag.
