Ferrovanadium

Ferrovanadium is a metal alloy containing vanadium with a minimum of 40% and a maximum of 80%. The production process of this metal alloy takes place through oxygen reduction and other scientific stages. This metal alloy is used as a strengthening, hardening, and wear-resistant agent. One advantage is its use for wear-resistance in steels with low alloy content but high strength.

The appearance of ferrovanadium is lumpy and has a silver color. Vanadium is stable under natural conditions and there is no problem using it under normal circumstances; however, it is best to avoid exposing this product to moisture, water, acids, and intense oxidation. Preparation and transport of this product according to European standards are completely safe.

Considering that ferrovanadium is a metal alloy, it is obtained from the combination of iron and vanadium, and during production, it is recognized as a solid crystalline silver material with a somewhat grayish tint. Most of the vanadium extracted from the earth’s surface is used to produce ferrovanadium. This alloy has unique features that we will discuss below.

Ferrovanadium

Ferrovanadium is used to add anti-corrosion properties to steels that have fewer alloying elements. These types of steels have high strength despite having a low level of alloy elements. Additionally, ferrovanadium is used in tools, alloys, the automotive industry, and many other applications. Major producers of ferrovanadium are mostly China and India.

Given the use of ferrovanadium as an additive in melting, the steel industry is the largest consumer of this product. Applications of this alloy in the steel industry include building structures, rail steels, carburizing steels, industrial tools, stainless steels, etc. By adding vanadium to steel, its strength and resistance are significantly increased, widely utilized in manufacturing bicycles, gears, automotive, and other functional components.

Vanadium, as well as being used as a hardening and strengthening additive for steels such as high-strength low-alloy (HSLA) steels and tool steels, also serves as an anti-corrosion additive in these steels.

Ferrovanadium was first used in the construction of Ford automobiles and still finds use in the automotive industry. This substance, as an additive in the production process of ferroalloys, introduces desirable properties in new compounds. One of the main advantages of adding ferrovanadium to alloys is its stability against alkalis, sulfuric acid, and hydrochloric acid. Furthermore, this additive renders the steel less sensitive to various corrosions. Ferrovanadium is also used to reduce the weight and increase the tensile strength of materials simultaneously.

Specifications of Ferrovanadium

The use of ferrovanadium may create pulmonary problems and is flammable when exposed to heat and flame, considered a high-risk alloy. This alloy is used for strengthening and hardening metals. It also reduces corrosion and the weight of products.

Production

Ferrovanadium is produced by three main methods:

1. Production of Ferrovanadium by Carbon Reduction:

In this method, vanadium is produced through reducing vanadium concentrate using carbon. This ferrovanadium contains approximately 85% vanadium by weight, 12% carbon, and 2% iron, and is produced in a vacuum furnace.

2. Production of Ferrovanadium by Silicon Reduction:

This method involves two stages, where vanadium is extracted from reducing vanadium concentrate using ferrosilicon. This ferrovanadium contains approximately 30% vanadium by weight, with undesirable amounts of silicon produced alongside it.

3. Production of Ferrovanadium by Aluminum Reduction:

In this method, vanadium oxide and aluminum, along with iron scraps, are charged into an electric furnace, and the reaction between aluminum and vanadium pentoxide begins. The result of this reaction is the production of ferrovanadium with more than 80% vanadium.

Types of Ferrovanadium

Ferrovanadium products are classified based on the percentage of vanadium they contain, usually ranging between 40% to 80%. These products are marketed in 1-ton jumbo bags or metal drums with dimensions ranging from 10 to 60 millimeters.

Features of Ferrovanadium:

Vanadium is a soft and ductile metal that hardens when combined with oxygen, nitrogen, carbon, and hydrogen. This product has a lower thermal conductivity than copper and a melting point of about 1890 degrees Celsius, a boiling point of about 3380 degrees Celsius, and a density of 11.6 grams per cubic centimeter. It is used as an additive in the production of ferrous products, adding various features that lead to the production of high-quality products.

The addition of this alloy results in steels with reduced corrosion and is used to increase the strength and reduce the weight of the final product. Ferrovanadium is used in various steels such as carburizing steels, rail steels, building structures, and in various industrial tools and stainless steels.

Applications of Ferrovanadium

With ferrovanadium, its most important application is in the steel industry where it is added as an additive. Products produced using ferrovanadium have high resistance to corrosion, rust, and other factors. Vanadium can be introduced as a strong carbide, forming carbide particles in steel and essentially limiting grain boundary movement during heat treatment.

Fine-grained steel produced with this product is more impact-resistant than coarse-grained steel and significantly prevents cracking. It should be noted that vanadium-containing steels are used in cutting tools because they are highly resistant to wear. Vanadium is also used in jet aircraft engines and turbine blades.

The largest application of ferrovanadium is in the alloying process of any hard steel, with the resulting alloyed steel used in gears, shafts, crankshafts, bicycle frames, and other very critical steel components. The characteristics of ferrovanadium include forming fine grains, increasing hardness, and resistance to wear in the steel industry.
