Ferrovanadium Smelting Furnace
High-Performance Vanadium Alloy Production by HANI Metallurgy
Engineered for High-Strength Steel Additives
The Ferrovanadium Smelting Furnace is a high-tech metallurgical unit designed for the production of ferrovanadium alloys, which are critical additives for improving the strength, toughness, and heat resistance of steel. As a specialized Ferrovanadium Furnace, it typically utilizes the silicothermic or aluminothermic reduction of vanadium pentoxide (V2O5) or vanadium trioxide (V2O3) in the presence of iron scrap. At HANI, we have developed state-of-the-art vanadium alloy smelting technologies that ensure high recovery rates and low energy consumption. Our SAF for ferrovanadium is engineered to withstand the extreme temperatures and chemical reactivity of vanadium slags, providing a stable platform for the production of standard FeV50, FeV80, and specialized high-purity vanadium alloys.
A HANI Ferrovanadium Smelting Furnace is more than just a heating vessel; it is a precision refining system. Vanadium is an expensive and sensitive metal; therefore, the Ferrovanadium Furnace must minimize losses to the slag and gas phases. By integrating advanced transformer technology with intelligent electrode control, HANI’s vanadium alloy smelting units allow for the precise control of the reduction kinetics. Our SAF for ferrovanadium units are widely used in the production of carbon steels, low-alloy high-strength steels, and tool steels, where vanadium’s grain-refining properties are indispensable.

Chemical Basis of Vanadium Smelting
The production of ferrovanadium in a Ferrovanadium Smelting Furnace typically involves the reduction of vanadium oxides. In the silicothermic process, ferrosilicon is used as the reducing agent in a Ferrovanadium Furnace. The presence of lime (CaO) is essential to neutralize the SiO2 produced, keeping the slag fluid and the vanadium recovery high in the vanadium alloy smelting process.
Principal Reactions in SAF for Ferrovanadium:
1. 2V2O5 + 5Si → 4V + 5SiO2 (Silicothermic Reduction)
2. 3V2O5 + 10Al → 6V + 5Al2O3 (Aluminothermic Reduction)
3. SiO2 + CaO → CaSiO3 (Slag Formation)
HANI’s Ferrovanadium Smelting Furnace is optimized to manage these exothermic reactions. Our SAF for ferrovanadium design allows for controlled feeding of reductants to prevent localized overheating and vanadium volatilization. By maintaining a high-basicity slag in the vanadium alloy smelting hearth, we ensure the final ferrovanadium product has a low silicon or aluminum content, meeting the highest grade specifications.
