COMPLEX FLUX FOR REMOVAL OF VANADIUM FROM CAST IRON Russian patent published in 2000 - IPC

Abstract RU 2148654 C1

FIELD: ferrous metallurgy, more specifically, compositions of fluxes. SUBSTANCE: complex flux for removal of vanadium from cast iron in oxygen converter has mill scale with additional introduction of nonfluxed pellets from titanomagnetite ores 5.2-12.4 mm in diameter and ratio FeO/F₂O₃ = 0.05-0.30, with the following amounts of components, wt.%: nonfluxed pellets of titanomagnetite ore, 50-85; mill scale, the balance. EFFECT: increased withdrawal of vanadium into commercial slag and its quality characterized by size of spinnelide grain and quantity of metal inclusions; higher output of liquid metal and reduced cost of vanadium conversion. 2 cl, 1 tbl, 1 ex
