Submerged Arc Furnace for Ferrovanadium
Advanced Smelting Furnace Solutions by HANI Metallurgy
The Standard in Vanadium Metallurgy Efficiency
The Submerged Arc Furnace for Ferrovanadium is a sophisticated smelting furnace designed for the high-efficiency production of vanadium-iron alloys. In a typical SAF ferrovanadium operation, the electrode tips are submerged within the material layer, providing a concentrated heat source that drives the reduction of vanadium oxides (V2O5 or V2O3). At HANI, we have optimized the smelting furnace design to manage the high basicity and chemical reactivity of vanadium-rich slags. Our Submerged Arc Furnace for Ferrovanadium is built with precision automation and robust electrical systems, ensuring that producers can achieve ultra-high recovery rates while maintaining the lowest specific energy consumption in the industry.

Precision Refining in HANI Smelting Furnace
The HANI Submerged Arc Furnace for Ferrovanadium utilizes high-purity graphite electrodes to eliminate carbon contamination during the refining stage. In a smelting furnace, the control of the slag-to-metal ratio is critical. HANI’s SAF ferrovanadium design incorporates advanced PLC logic that adjusts the material feed based on the chemical analysis of the input ores. This ensures that the Submerged Arc Furnace for Ferrovanadium maintains a high-purity output, making it ideal for the production of aerospace-grade vanadium master alloys.
Additionally, our smelting furnace technology features a modular shell design that allows for rapid refractory relining. In the SAF ferrovanadium process, the slag is highly aggressive; by using high-density magnesia-chrome bricks and targeted water cooling in the Submerged Arc Furnace for Ferrovanadium, we extend the hearth life and minimize maintenance downtime.
