Ferro vanadium

Ferro vanadium is mainly used as an alloying additive in steelmaking. After adding ferro vanadium to steel, it can significantly improve the hardness, strength, wear resistance and ductility of steel, and improve the cutting performance of steel. Ferro vanadium is commonly used in carbon steel, low alloy steel strength steel, high alloy steel, tool steel and cast iron. use
1. The purpose of ferro vanadium is to smelt 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 grains, increases the strength of steel, and inhibits its aging effect; in alloy structural steel, vanadium refines grains, increases the strength and toughness of steel; in spring steel, it can be combined with chromium or manganese combined. Cooperating with it can improve the elastic limit of steel and the quality of steel; in tool steel, it mainly refines the structure and grain of steel, increases the tempering stability of steel, enhances its secondary hardening effect, improves its wear resistance, and prolongs the The service life of tools; in heat-resistant steel and hydrogen-resistant steel, vanadium also plays a beneficial role; adding vanadium 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 even, the grains of the matrix are refined, thereby improving the hardness, tensile strength and wear resistance of cast iron.

2. Ferro vanadium: Ferro vanadium is an iron alloy obtained by reducing vanadium pentoxide with carbon in an electric furnace or reducing vanadium pentoxide with silicon thermal method in an electric furnace. It is widely used as an element additive for smelting vanadium-containing alloy steel and alloy cast iron, and is also used in the manufacture of permanent magnets.
