Abstract
A method of alloying steel with vanadium by means of vanadium converter slag is considered. Thermodynamic analysis of the reduction of the oxides in vanadium slag during ladle treatment of the steel permits determination of the process parameters. The reduction of elements from oxides present in vanadium slag-in particular, vanadium, iron, and manganese-is evaluated in terms of the residual content of the corresponding oxides. It follows from thermodynamic calculations and experiments that, with optimal proportions of the reducing agents, relatively complete reduction of vanadium (98–99%) and iron from vanadium converter slag by carbon and silicon is possible, with limited reduction of titanium and manganese.
