Ferrovanadium is obtained by reducing vanadium pentoxide with carbon in an electric furnace, or it can also be obtained by reducing vanadium pentoxide by the silicon thermal method of an electric furnace. It is widely used as an element additive in smelting vanadium-containing alloy steel and alloy cast iron. In recent years, it has been used to make permanent magnets.
FeV alloy
Mainly used for smelting alloy steel. About 90% of the vanadium 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 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.
