brief introduction
product information
Ferrovanadium is a ferroalloy that is reduced with carbon in an electric furnaceVanadium pentoxideIt can also be obtained by reducing vanadium pentoxide by the electric furnace silicon thermal method. It is widely used in the smelting of vanadium-containing alloy steels andAlloy cast ironadditives are also used to make permanent magnets. There are V401, V402 and other varieties of ferrovanadium produced in China, which contain about 40% vanadium.
It is mainly used for smelting alloy steel. About 90% of the vanadium consumed in the world is used in the steel industry. Vanadium inOrdinary low-alloy steelThe main thing is to refine the grain, increase the strength of the steel and inhibit its aging effect; In alloy structural steel, it is to refine the grain and increase the strength and toughness of the steel; Use in combination with chromium or manganese in spring steels to increase the elastic limit of the steel and improve its quality; In the tool steel, the structure and grain of the steel are mainly refined, the tempering stability of the steel is increased, its secondary hardening effect is enhanced, its wear resistance is improved, and the service life of the tool is prolonged. In heat-resistant and hydrogen-resistant steels, vanadium also plays a beneficial role; The vanadium added to the cast iron promotes the formation of pearlite due to the formation of carbides, which makes the cementite stable, the shape of the graphite particles is fine and uniform, and the grains of the matrix are refined, so that the hardness, tensile strength and wear resistance of the casting are improved.
