Ferro Vanadium With Nice Quality

Ferrovanadium is an iron alloy composed of iron and vanadium, with a vanadium content usually ranging from 35% to 85%. This alloy is mainly obtained by reducing vanadium pentoxide in an electric furnace using carbon or silicon thermal method.

Ferrovanadium is an important additive in the steel industry. It can significantly improve the strength, toughness, wear resistance and corrosion resistance of steel, while improving the welding performance and low-temperature toughness of steel. In the production of alloy steel, ferrovanadium is used to refine grains, increase the strength and toughness of steel, and improve the quality of steel. 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, increasing 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 grains of steel, increases the tempering stability of steel, enhances its secondary hardening effect, improves its wear resistance, and prolongs The service life of the tool; in heat-resistant steel and hydrogen-resistant steel, vanadium also plays a beneficial role; the vanadium added to cast iron promotes the formation of pearlite due to the formation of carbides, stabilizes cementite, and the shape of graphite particles is fine and Uniform and refine the grains of the matrix, thereby improving the hardness, tensile strength and wear resistance of the casting.

Ferrovanadium is suitable for alloy steel smelting, alloy element additives and stainless steel welding rod coatings. About 90% of the vanadium consumed in the world is used in the steel industry. The consumption ratio of vanadium 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.

Ferrovanadium can be used to manufacture new energy equipment such as high-efficiency batteries and fuel cells. In particular, the application of vanadium is gradually increasing in energy storage technologies such as all-vanadium liquid flow batteries. In the metallurgical industry, the use of ferrovanadium can extend the service life of smelting furnace bricks and reduce production costs. In summary, ferrovanadium, as a multi-purpose alloy material, has important application value in many fields such as steel, aerospace, and electronic devices.
