Ferro Vanadium Alloy is an iron alloy composed of vanadium and iron. It is obtained by reducing vanadium pentoxide with carbon in an electric furnace. It can also be obtained by reducing vanadium pentoxide by the silothermal method of an electric furnace. It is widely used as an element additive in smelting vanadium-containing alloy steel and alloy cast iron, and is also used to make permanent magnets. Ferrovanadium produced in China includes V401, V402 and other varieties, containing about 40% vanadium.

 

 

Ferrovanadium 60 is used as an additive to improve the quality of ferrous alloys. One use is to improve corrosion resistance to alkaline agents as well as sulfuric and hydrochloric acids. It is also used to increase the tensile strength to weight ratio of a material. One application for this steel is in high-pressure, high-throughput fluid handling systems used in the chemical processing industry to handle industrial-scale sulfuric acid production. It is also commonly used in hand tools such as wrenches, screwdrivers, ratchets, etc.

Ferrovanadium 80 is a moderately hard and ductile silver-gray transition metal. Some descriptions describe it as "soft", probably because of its ductility. Not easy to corrode, it is quite stable in alkali, sulfuric acid and hydrochloric acid. It is oxidized to vanadium pentoxide (V2O5) at temperatures above 933K (660 degree ).

 

       Massive Ferrovanadium 80 slices with a purity of 99.95%.An interesting experiment involves using zinc to reduce colorless ammonium vanadate (NH4VO3). During the experiment, vanadium was successively reduced to blue tetravalent vanadium, green trivalent vanadium, and purple-blue divalent vanadium. Later, the low-priced vanadium was oxidized to golden pentavalent vanadium by oxygen in the air. vanadium. Because vanadium's valence can easily change, it is also often used as a catalyst. Vanadium with +1 valence rarely appears. Theoretically, 0, -1 and -3 valence vanadium are also possible.

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 alloy composition reaches the requirements, the slag and ferrous alloy can be 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 to 60% vanadium. The recovery rate of vanadium can reach 98%. Refining each ton of ferro vanadium  alloy consumes about 1,600 kilowatt hours of electricity.

 

 

Thermite method uses aluminum as the reducing agent and smelts using the lower ignition method in a furnace barrel lined with an alkaline furnace. First put a small part of the mixed charge into the reactor and ignite it. After the reaction starts, add the remaining materials one after another. It is usually used to smelt high-vanadium iron (containing 60-80% vanadium). The recovery rate is slightly lower than that of electrosilicothermal method, about 90-95%.

 

 

 

Ferrovanadium 40 50  is an important alloy additive in the steel industry. Vanadium increases the strength, toughness, ductility and heat resistance of steel. Since the 1960s, the use of vanadium in the steel industry has increased dramatically, accounting for 85% of vanadium consumption by 1988.

The consumption ratio of Vanadium Iron Alloy in steel is 20% for carbon steel, 25% for high-strength low alloy steel, 20% for alloy steel, and 15% for tool steel. Vanadium-containing high-strength low-alloy steel (HSLA) is widely used in the production and construction of oil/gas pipelines, buildings, bridges, rails, pressure vessels, carriage frames, etc. due to its high strength.

 

 

Application fields: Mainly used for smelting alloy steel. About 90% of the Ferro vanadiums Alloy consumed in the world is used in the steel industry. In ordinary low alloy steel, vanadium mainly refines the grains, increases the strength of the steel and inhibits its aging effect; in alloy structural steel, it refines the grains, increases the strength and toughness of the steel. In spring steel, it interacts with chromium or manganese. Used together, it increases the elastic limit of steel and improves its quality.

 

In tool steel, it mainly refines the structure and grain of the steel, increases the tempering stability of the steel, enhances its secondary hardening effect, improves its wear resistance, and extends the service life of the tool; in heat-resistant steel and hydrogen-resistant steel , vanadium also plays a beneficial role.

 

FeV metal added to cast iron promotes the formation of pearlite due to the formation of carbides, stabilizes cementite, makes the shape of graphite particles fine and uniform, and refines the grains of the matrix, thereby improving the hardness, tensile strength and wear resistance of the casting. improve. In addition, about 10% of the vanadium  Iron on the market is used to produce titanium alloys required by the aerospace industry. Vanadium can be used as a stabilizer and strengthener in titanium alloys, making titanium alloys highly ductile and plastic. In addition, vanadium is used primarily as a catalyst and colorant in the chemical industry. Vanadium is also used in the production of rechargeable hydrogen batteries or vanadium redox batteries.
