Ferrovanadium smelting method
Electrosilicothermal method: Flake vanadium pentoxide uses 75% ferrosilicon and a small amount of aluminum as reducing agent, and is refined in an alkaline electric arc furnace through two stages of reduction and refining to obtain qualified products.
During the reduction period, all the reducing agents in one furnace and 60-70% of the total flaky vanadium pentoxide are put into the electric furnace, and silicon thermal reduction is carried out under high calcium oxide slag. When the V2O5 in the slag is less than 0.35%, the slag is released (called lean slag, which can be discarded or used as building materials) and enters the refining period.
At this time, flake vanadium pentoxide and lime are added to remove excess silicon, aluminum, etc. in the alloy liquid. Once the ferroalloy composition reaches the required level, the ferroalloy can be slag-discharged. The slag released in the later stage of refining is called rich slag (containing V2O5 up to 8~12%) and will be returned to the furnace for reuse when charging begins in the next furnace.
The alloy liquid is generally cast into cylindrical ingots, and the finished product is obtained after cooling, demoulding, crushing and slag removal. This method is generally used for smelting ferrovanadium containing 40~60% vanadium. The recovery rate of vanadium can reach 98%. Refining each ton of ferrovanadium consumes about 1,600 kilowatt hours of electricity.
