PURPOSE: To oxidize and remove V as slag without oxidizing Cr in a ferroalloy, by adding a flux having BaO and Cr2O3 as main components in the molten ferroalloy contg. V and Cr.

CONSTITUTION: For removal of V in steel having Cr such as stainless steel, a flux consisting of BaO, Cr2O3, and alkaline earth metallic halides such as BaCl2, BaF2, CaCl2 or the like is added to the molten ferroalloy contg. Cr. In this case, first, a mixture consisting of components free from oxidizing agent such as Cr2O3 is added and the oxidizing agent consisting essentially of Cr2O3 is added slowly to bring them into reaction while stirring. Vanadium in the molten metal is oxidized to V2O3 by Cr2O3, and removed by forming a stable slag with basic BaO. Cr2O3 used as the oxidizing agent for V is reduced to Cr, and V is removed without causing any loss of Cr.
