Application of Ferro Vanadium
Ferrovanadium is mainly used as an alloy additive in steelmaking. After adding iron vanadium to steel, the hardness, strength, wear resistance and ductility of steel can be significantly improved, and the cutting performance of steel can be improved. Iron vanadium is commonly used in carbon steel, low alloy steel strength steel, high alloy steel, tool steel and cast iron production.
Vanadium ferro alloys types are suitable for alloy steel smelting, alloying element additive and stainless steel electrode coating.
Production Process of Ferro Vanadium
Electro-silicothermic process
With 75% ferrosilicon and a small amount of aluminum as reducing agent, the flake vanadium pentoxide was purified in alkaline electric arc furnace through two stages of reduction and refining. During the reduction period, all the reducing agent of the first furnace and the sheet vanadium pentaoxide accounting for 60 ~ 70% of the total amount were loaded into the electric furnace, and silicon thermal reduction was carried out under the high calcium oxide slag. When the V2O5 in the slag is less than 0.35%, the slag is released (called poor slag, can be discarded or used as building materials), into the refining period. At this time, flake vanadium pentaoxide and lime are added to remove the excess silicon and aluminum in the alloy liquid. When the alloy composition meets the requirements, the iron alloy can be slag out. The slag released in the later stage of refining is called rich slag (containing V2O5 up to 8 ~ 12%), which is returned to use when the next furnace begins to feed. The alloy liquid is generally cast into cylindrical ingot, which is finished after cooling, demolding, crushing and slag removal. This method is generally used for smelting iron vanadium containing 40 ~ 60% vanadium. The recovery rate of vanadium is up to 98%. Refining consumes about 1600 kilowatt-hours per ton of iron vanadium.
Thermite process
Smelting with aluminum as reducing agent is carried out by lower ignition in a barrel lined with alkaline furnace. First, a small part of the mixed charge is loaded into the reactor, that is, ignition. After the beginning of the reaction and then add the rest of the charge. Is typically used for smelting Gao Fantie (containing vanadium 60 ~ 80%), the recovery rate was slightly lower than electrical silicon thermal method, about 90-95%.
Features of Ferro Vanadium
01.
Ferrovanadium is an important alloy additive in iron and steel industry. Vanadium improves the strength, toughness, ductility and heat resistance of steel.
02.
High strength low alloy steel (HSLA) containing vanadium is widely used in the production and construction of oil/gas pipelines, buildings, Bridges, rails, pressure vessels, carriage frames and so on because of its high strength.
03.
The application range of various vanadium steel is more and more wide, and the related talents are more and more important.
