Smelting Technology for High‑Vanadium Ferroalloys

Techniques for Producing FeV with ≥60% V
Producing high‑vanadium ferroalloys​ (FeV60, FeV80) requires precise control to maximize V recovery and minimize impurities.
Technology
Key Aspects
Advantages
Challenges
Aluminothermic batch smelting
Sealed or semi‑sealed crucibles; high exotherm ensures complete reduction
High V yield (>95%); simple setup
Al content in alloy; batch‑scale only
Vacuum induction melting (VIM)
Reduce V₂O₅ in vacuum with Fe and C; refine alloy
Low gas content, ultra‑pure FeV
High capital & energy cost; small scale
Plasma arc melting
Use plasma torch for high‑T reduction in controlled atmosphere
Precise atmosphere control; low contamination
Expensive; mainly R&D/commercial specialty
Combined Si/Al reduction in EAF
Optimize Si:Al ratio to tailor impurity profile
Flexible grade production
Requires careful slag chemistry control
Process Goals for High‑V Alloys
  • Maximize V recovery​ from V₂O₅ (>98%).
  • Minimize Al, Si, C​ for low‑carbon steel applications.
  • Achieve uniform composition​ and low gas (O, N)​ content.
