Abstract
Abstract. The paper considers some points of carbon-silicon thermal reduction of elements from oxides containing in converter vanadium stag while steel processing at the ladle-furnace installation. The authors described the physical-and-chemical model of the process and results of thermodynamic simulation which allowed determining the optimal consumption of slag and restorers for complete restoration of vanadium from converter vanadium slag. Simultaneous steel blowing by gaseous nitrogen at steel alloying by vanadium results in complete vanadium extraction and obtainment of a consolidating phase-carbides and carbonitrides of vanadium. Nitrogen, dissolved in metal, interacts with restored vanadium, carbide of vanadium on the nanolevel forming nitrides and carbonitrides of vanadium.
