Ferrovanadium (FeV) is a key alloy in modern metallurgy, consisting of iron and vanadium, with the vanadium content ranging from 35% to 85%. This grey-silver crystalline solid is usually processed into a fine powder, called "ferrovanadium powder", and is mainly used as an additive to enhance the properties of steel and other ferroalloys. Its ability to increase strength, hardness and corrosion resistance makes it an indispensable material in industries ranging from construction to chemical processing. This article explores the production, applications and economic significance of ferrovanadium, and provides a comprehensive overview of its role in industrial applications.

Refractory Slide Gate is a sliding valve device made of high-performance refractory materials, mainly used for flow control of high-temperature molten metal (such as molten steel, molten iron) in the metallurgical industry. Its core function is to adjust the water inlet opening by sliding, so as to achieve precise opening and closing and flow regulation of the metal liquid flow. It is an indispensable key component in the continuous casting process.

Ladle refractory materials are key materials used in the steelmaking process to protect the ladle lining and withstand the erosion of high-temperature molten steel and slag. As the main container for holding and transporting molten steel (from converter/electric furnace to continuous casting tundish), the refractory materials of the ladle need to remain stable under extreme thermodynamic and chemical conditions, while adapting to frequent molten steel impact, temperature changes and violent reactions at the slag-steel interface. The following are the key components, performance requirements and technical challenges of ladle refractory materials。

Flake vanadium pentoxide (V₂O₅ Flake) is a form of vanadium pentoxide, which is golden or orange-yellow flake crystals with good chemical stability and redox properties. Compared with powder, the flake structure has higher crystallinity and better purity, which is convenient for storage and transportation and use, and is often used in high-end application fields.

Ferroalloy is one of the important raw materials for producing alloy and special steel. It is used as deoxidizer and alloy additive in the steel production process to give steel special properties, such as improving corrosion resistance, improving high temperature hardness and strength, improving wear resistance and abrasion resistance, and improving creep strength.

Refractory nozzle is a refractory material product used for high-temperature molten metal (such as molten steel, molten iron) or non-metallic melt flow control, usually installed in the outlet or sliding nozzle system of metallurgical equipment (such as ladle, converter, tundish).
