Products Description
The vanadium content of ferro vanadium 80 is about 78%~82%. There are many raw materials used to produce vanadium, such as vanadium titanium magnetite, which contains VO.4%~1.4% vanadium; uranium vanadium ore, which contains 1.5%~2.0% V2O5; crude oil ash, which contains 20%~40% V2O5 %; vanadium-containing phosphorus iron, containing V3% to 6%; waste vanadium catalysts and residues from alumina production, etc. These different feedstocks provide diverse sources for vanadium production.
In short, although the distribution of vanadium on the earth is relatively limited, it has important application value in various fields.
The smelting process takes place in two steps. The first step is the reduction period, using ferrosilicon and aluminum to reduce vanadium oxide to obtain a vanadium ferrosilicon alloy with high silicon content; the second step is the refining period, using slag with high V2O5 to refine the vanadium ferrosilicon alloy to reduce the silicon and obtain ferrovanadium. After the last furnace is discharged and the furnace repair is completed, all the iron materials required to produce ferrovanadium components are added. After the electricity is turned on, the refining slag from the previous furnace is returned to the furnace, and the first batch of reducing raw materials (vanadium pentoxide flakes) are added. , lime and most of the ferrosilicon in the ingredients). When the molten pool is formed, power is supplied at full load to melt the charge quickly. After full melting, the power supply load is appropriately reduced, and after adding the remaining ferrosilicon, the V2O5 in the aluminum reduction slag is added. Stir the molten pool thoroughly, and when the (V2O5) in the slag is <0.35%, the slag will be discharged. After slag discharging, add the second batch of reducing materials (a mixture of vanadium oxide flakes and lime). Stir thoroughly after complete melting. Ferrosilicon is added first, and then aluminum blocks are added to reduce the slag. When the content of the slag (V2O5) is less than 0.35%, the slag is released. The amount of materials added and the number of batches during the reduction period are determined by the vanadium content (40% to 60%) of the ferrovanadium produced.
