Ferrovanadium

Ferrovanadium is highly-demanded in metallurgy due to its irreplaceability in melting most structural, instrument and bearing steel.

Metotechnics company offers ferrovanadium. For this call us, send a request via e-mail or make an order on the Price list page of our website.

See the corresponding sections of this page for the detailed description of the methods of production, grades and recommendations for application of our products. Also there are some references to standards that serve as important sources of technical information.

Grades

Ferrovanadium grades consist of two parts: the first one is vanadium (V) content, the second one - carbon (C) content. E.g., FeV50У0,4 - ferrovanadium with weight per cent of V 48-60% and weight per cent of С - 0.4%.

The standard regulates several grades with different V content: FeV50У0,4; FeV50У0,75; Fev40У1, etc. Besides vanadium and carbon, ferrovanadium grades also contain a significant percentage of silicon (Si) - 1.8-2.0% depending on the grade, manganese (Mn) - 0.2-6.0% and aluminum (Al) - 0.2-2.5%. Iron (Fe) is an important FeV component and its percentage is rather high, although not regulated by the standards.

Ferroalloys usually contain such admixtures as sulphur (S) and phosphorus (P) that that transit from ores.

Ferrovanadium chemical composition is given in GOST 27130-94.

Production

FeV is produced by reduction, so as other ferroalloys. Aluminum, (Al), carbon (C) and silicon (Si) are the most common reducing reagents. Al and Si are usually applied.

Although vanadium is a rare metal, its content in the Earth crust is rather high, if compared with molybdenum and tungsten. Several minerals contain V; they can be classified as follows: vanadium ore (more than 3% of V2O5); multimetal vanadium ores (non-ferrous and rare metals)(greater than or equal to 1% of V2O5), ferrous metals (less than 1% of V2O5); combustibles and other natural resources (less than 1% of V2O5). Certain commercial ores include: VS2, vanadium-containing titanomagnetite (Fe, V, Ti)3O4, vanadite [VO4]Pb5Cl.

Ferrovanadium production is more sophisticated, if compared with ferromolybdenum or ferrotungsten. For obtaining vanadium pentoxide (V2O5), that serves as raw materials for FeV, firstly the ore should be melted in a blast furnace for making vanadium cast iron. Then it should be melted in a convector for making vanadium-containing slag that should be hydrometallurgically processed for extracting V2O5. Ferrovanadium is melted in electric-steelmaking furnaces.

FeV is supplied in form of slugs with weight that does not exceed 5 kg.

Supply condition, batch selection principles and other requirements towards ferrovanadium are given in GOST 27130-94.

Application

The main ferrovanadium application is alloying of steel and cast iron (so as one of ferromolybdenum, ferrotungsten and most other ferroalloys). So this material is the most highly-demanded in ferrous (85%) and non-ferrous (8-10%) metallurgy.

Adding vanadium to steel makes its structure less coarse. In turn, this increases the wear resistance, viscosity, durability and plasticity. Adding V to cast iron prevents its greying and increases its impact strength. Vanadium-alloyed steel is divided into the following classes: high-strength construction steel for welded structural steel; chromium-vanadium machine heat treatable steel; instrument and bearing steel.
