FeV

Ferrovanadium this ferroalloy containing mainly vanadium 35-50%, 1-3% Si, 0,5-1,5% of aluminum (the rest iron and impurities). In Russia, ferrovanadium receive arc furnace steel type with magnesite, lining restoration V2O5 and converter slag with partial use of aluminum powder. Melting lead in 2 periods: the first - a thorough restoration of vanadium raw materials, products alloy Capital melting (converter slag, V2O5, slag second period), when giving in charge of lime, fluorspar, and elected ferrosilicon as a reductant. Metal first period contains 35-40% vanadium, 9-12% silicon, and slag - £ 0,35% V. Then the slag drain and a second period. The main task - refining the metal of the first period of silicon. In the oven served V2O5 and lime in a ratio of 1:1 to the metal content in the <2% silicon. Products melting the second period (ferrovanadium and slag with 10-15% V2O5) in the cast iron drain, footer. Then the vanadium slag is returned to the oven for the first time and ferroalloy divide. Ferrovanadium used primarily for alloying steel and cast iron. In addition to producing ferrovanadium silicon-vanadium, smelt in the electric, as well as metal and vanadium rich ferrovanadium (<80% V) obtained alumotermic way.
