How to Make Ferro Vanadium 80? A Step-by-Step Production Guide
Ferro Vanadium 80, also called FeV 80, Iron Vanadium Alloy, or Vanadium Iron, is a high-purity ferroalloy with approximately 80% vanadium content. Its production is a sophisticated metallurgical process designed to maximize vanadium recovery while minimizing impurities. As a leading supplier of Industrial Ferrovanadium, ZhenAn Company understands the intricacies of creating top-tier Fe-Vanadium alloys that meet global standards. Here's an overview of how Ferro Vanadium 80 is made.
1. Raw Materials Selection
The primary raw materials for Ferro Vanadium 80 are:
Vanadium Pentoxide (V₂O₅): The main vanadium source, typically derived from vanadium-bearing magnetite ore or as a byproduct of uranium/phosphate processing.
Iron Source: Usually metallic iron scrap or iron oxide, added to dilute vanadium to the desired concentration.
Reducing Agent: Aluminum powder or ferrosilicon is commonly used to facilitate the reduction reaction.
Fluxes: Calcium oxide (lime) or calcium fluoride may be added to remove impurities and improve slag fluidity.
2. Core Production Process: Aluminothermic Reduction
The most widely used method for producing high-purity Ferro Vanadium 80 is the aluminothermic reduction process, conducted in an electric arc furnace or refractory-lined reactor.
Step 1: Mixing Raw Materials
V₂O₅, iron powder, aluminum powder, and fluxes are precisely weighed and mixed to achieve the target 80% vanadium content. The stoichiometric ratio is critical to ensure complete reduction of vanadium oxide.
Step 2: Reaction Initiation
The mixture is ignited in a sealed reactor, triggering an exothermic thermite reaction. Aluminum reduces V₂O₅ to metallic vanadium, which then combines with iron to form the alloy:
3V2O5+10Al+3Fe→6V+5Al2O3+3Fe
The reaction generates intense heat (up to 2000°C), melting the alloy and forming a slag layer of aluminum oxide and impurities.
Step 3: Separation and Refining
Molten Ferro Vanadium 80 settles at the bottom of the reactor, while the lighter slag floats on top. The alloy is tapped off, and residual slag is removed to further purify the material. Additional refining steps, such as vacuum degassing, may be employed to reduce trace impurities like silicon or carbon.
3. Key Process Parameters
Controlling process variables is essential to ensure consistent quality:

4. Quality Control and Testing
After production, Ferro Vanadium 80 undergoes rigorous testing:
Chemical Analysis: X-ray fluorescence (XRF) or inductively coupled plasma (ICP) spectroscopy confirms vanadium content (≥80%) and impurity levels.
Physical Inspection: Checks for lump size, density, and absence of contaminants.
Packaging: Sealed in moisture-proof bags or drums to prevent oxidation during storage and transport.
