A: Controlling Al/Si residuals, preventing vanadium loss, and maximizing yield from expensive V₂O₅ feedstock.
Q: Physical properties of ferrovanadium – density, melting point, color?
A: Density ~6.0–7.0 g/cm³, melting point ~1500–1700 °C (depends on grade), silver‑gray metallic color.
Q: Chemical properties of ferrovanadium – reactivity with acids?
A: Reacts with strong acids, liberating hydrogen and forming vanadium/iron salts; resistant to weak acids.
Q: Vanadium content range in different ferrovanadium grades?
A: FeV40: ~38–42% V; FeV60: ~58–62% V; FeV80: ~78–82% V.
Q: Particle size and morphology of ferrovanadium – lump vs powder?
A: Lump: irregular chunks; powder: fine granules for easier alloying; morphology affects dissolution rate.
Q: Thermal stability of ferrovanadium at high temperatures?
A: Stable up to melting point in inert/vacuum; in air, surface oxidizes above ~600 °C forming vanadium oxides.
Q: What are the applications of ferrovanadium in the steel industry?
A: Used to add vanadium for strengthening, grain refinement, and hardenability in carbon, alloy, and HSLA steels.
Q: What is the role of ferrovanadium in high strength low alloy steel (HSLA)?
A: Enhances strength and toughness through precipitation of vanadium carbides/nitrides, allowing lighter, stronger structures.
Q: What is the use of ferrovanadium in tool steels and die steels?
A: Improves wear resistance, hot hardness, and toughness for cutting and forming tools.
Q: How is ferrovanadium used in the automotive industry for lightweight high strength components?
A: Enables thinner, stronger parts with weight savings, improving fuel efficiency and crash performance.
Q: What is the role of ferrovanadium in aerospace alloys for improving fatigue resistance?
A: Refines microstructure and increases strength, enhancing fatigue life of critical aircraft components.
Q: How is ferrovanadium used in rebar production for enhancing corrosion resistance?
A: Promotes finer grain structure and precipitation strengthening, indirectly improving durability in concrete reinforcement.
Q: What are the international standards for ferrovanadium – ASTM, ISO?
A: ASTM A182, ASTM A731, and ISO 5445 cover chemical composition and quality requirements for ferrovanadium grades.
Q: What is the national standard of ferrovanadium in China – GB?
A: GB/T 4139 specifies grades, chemical composition, and testing methods for ferrovanadium in China.
Q: What are the purity requirements for ferrovanadium – vanadium recovery rate?
A: High purity ensures effective vanadium recovery (>95%) in steelmaking; limits impurities that affect steel properties.
Q: What are the impurity limits in ferrovanadium – aluminum, silicon, carbon?
