Description

ZhenAn International Co., Limited is one of the most reliable manufacturers and suppliers of ferrovanadium for steelmaking and foundry in China. With abundant experience, we warmly welcome you to wholesale discount ferrovanadium for steelmaking and foundry in stock here from our factory. Quality products and reasonable price are available.

Application Field

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 grains, increases the strength of steel and inhibits its aging effect; in alloy structural steel, it refines grains, increases the strength and toughness of steel; in spring steel

it is combined with chromium or manganese Use together to increase the elastic limit of steel and improve its quality; 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 service life of tools

in heat-resistant steel and hydrogen-resistant steel, vanadium also plays a beneficial role; 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, thus improving the hardness, tensile strength and wear resistance of the casting.
Production Process

Products Process

The abundance of vanadium in the earth's crust is 135×10%. There are more than 70 kinds of vanadium minerals, but there are few single vanadium deposits (only Minaragra in Peru is a single deposit. It has been mined.), and they are all symbiotic with other mines.

The raw materials used to produce vanadium include vanadium-titanium magnetite (containing VO.4%~1.4%), uranium vanadium ore (containing V2O51.5%~2.0%), crude oil ash (containing V2O520%~40%), containing vanadium Ferrophosphorus (containing V3%~6%), waste vanadium catalyst, residue from alumina production, etc. These raw materials contain low vanadium, so hydrometallurgy is required.

First, vanadium pentoxide is extracted from these raw materials, and then vanadium pentoxide is smelted into ferrovanadium and vanadium additives. Vanadium-titanium magnetite concentrate is the main raw material for the production of vanadium, and 90% of the world's vanadium production is produced with this raw material.
