Experiment on Smelting Separationof VanadiumContaining Magnetic Materials in EBT Electric Arc Furnace
In order to recover vanadium slag from vanadium containing magnetic materials and directly use it in the production of flake V2O5,Pangang Titanium Industry has conducted exploratory experiment on smelting separation of vanadium containing magnetic materials in EBT electric arc furnaces for steel-making.Vanadium containing magnetic materials are melted and separated by EBT electric arcfurnace to obtain vanadium slag containing 11.11%~11.87%V2O5,with a vanadium recovery rate of 90.40%.By reducing the entry of residue from the previous furnace,scrapiron with low silicon are selected,and the[FeO]content is between 37.87%and 39.39%,the grade of V2O5 in the slag can be further improved.During the process of melting separation,the speed of adding vanadium containing magnetic materials to the top bin of the furnace is controlled at 100~150 kg/min,and the additional input power of the EBT electricarc furnace is increased to 5 340~8 010 kW with the furnace temperature below 1 420 ℃.It is practicable to recover vanadium from vanadiumcontaining magnetic materials by melting and separating them inEBT electric arc furnace.
