Products Description

Ferrovanadium is mainly used 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 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.

Used in combination with chromium or manganese in spring steel to increase the elastic limit of the steel and improve its quality; in tool

Steel it mainly refines the structure and grains of the steel, increases the tempering stability of the steel, and enhances its secondary hardening effect , improve its wear resistance and extend 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, makes the shape of graphite particles fine and uniform, and refines the matrix. grains, thereby improving the hardness, tensile strength and wear resistance of the casting.

Carvan vanadium and vanadium aluminum alloy are widely used vanadium additives. carvan is a high-carbon ferrovanadium additive for vanadium steel and vanadium-containing alloys. Its composition is V83% to 86%, C10.5% to 13%, and Fe2% to 3%. The production method is to use natural gas to reduce V2O5 to V2O4 in a rotary kiln at 600°C, and then use natural gas to reduce V2O4 into vanadium carbon oxides in another rotary kiln at 1000°C. Vanadium carbon oxide is added to coke or graphite by calculation.

The amount of carbon added is 1% excess than the calculated value of carbon-oxygen reaction. A mixture of vanadium carbon oxygen and graphite is pressurized into blocks. Place it in a vacuum furnace and heat it to 1000°C to make Carvan vanadium. The typical composition of Carvan vanadium produced by Union Carbide Company of the United States is: V84.5%, C12.25%, Si0.05%, Al0.005%, S0.004%, P0.004%, Fe2.5%. The shape of the alloy is flat cake. Density is 4.58g/cm. Car-van vanadium briquettes are packed into bags. Each bag contains 25 pounds of vanadium and 3.7 pounds of carbon. They can be directly added to the furnace or ladle for use without analysis.

Compared with ferrovanadium, Carvan vanadium is cheaper, dissolves faster after adding molten steel, and has a higher vanadium yield. When the briquettes of vanadium carbon dioxide and graphite are fed with nitrogen into the furnace during the sintering process, Nitrovan vanadium can be made, which contains V78% ~ 82%, C11% ~ 12%, and N2 ≥ 6.0%. Used for smelting vanadium-nitrogen steel.
