50%Min Purity Ferro Vanadium

Ferro vanadium is a product made by reducing vanadium oxides in vanadium-containing raw materials at high temperatures with a reducing agent to reduce them into metallic vanadium and melt them in molten iron. Silicon and aluminum are commonly used reducing agents for smelting ferrovanadium. Using silicon as a reducing agent to smelt ferrovanadium requires an external heat source. Since the smelting is carried out in an electric arc furnace, it is called the electric silicon thermal method. This method is widely used in smelting ordinary 50 ferrovanadium.

Like other ferroalloy smelting processes, the electric silicon thermal method for smelting 50 ferrovanadium is also an electric furnace reduction smelting process. The smelting dephosphorization principle is generally oxidative dephosphorization and reductive dephosphorization. Oxidative dephosphorization is to dephosphorize with the help of strong alkaline slag with large phosphorus capacity (such as alkali metal and alkaline earth metal oxide-based slag, etc.). Reductive dephosphorization uses strong reducing elements (such as CaMg, etc.) to dephosphorize. The principle is: ① With the help of an oxidant or a reducing agent, the P in the alloy is ionized (converted into an ionic state) and the corresponding salt substances are formed; ② With the help of an ionic slag phase, phosphorus is dephosphorized and fixed.
