Abstract
The electroaluminothermic process is considered for ferrovanadium production from a vanadium-containing charge mixture by reducing vanadium oxide with aluminum in a slag layer with simultaneous electrical heating of the slag bath. The key factors influencing the fundamental parameters of the process have been identified. Samples of final slag were examined, and chemical composition and metal particle distribution in the slag layer were determined. 15 Ref., 4 Tabl., 7 Fig.
Keywords: electroslag process, ferrovanadium, electroaluminothermic reduction, slag, chemical composition, metal, inclusions
