Abstract
The invention relates to metallurgy, namely to the production of ferroalloys with aluminothermal method. An out-of-furnace aluminothermal method for obtaining of ferrovanadium comprises the preparation of charge – vanadium-containing material with introduction into it of reducing agent – ferroaluminium alloy or aluminium powder, or their mix and fining mix, which is loaded on the bottom of smelting unit, at that reducing agent and vanadium-containing material in charge are differentially distributed, two independent particles of charge, at that in the top part of charge is introduced of 85÷95 w/w of vanadium-containing material, intended for melting, all reducing agent, which makes of aluminium surplus of 130±5 % from stoichiometric necessary for reduction of vanadium, and fluxing impurities, and in the bottom part of charge is introduced of surplus of 5÷15 w/w of vanadium-containing material and fluxing impurities. The smelting of ferrovanadium on this method will allow increase of vanadium extraction in finished product with out-of-furnace method and without additional power inputs.
