Submerged Arc Furnace for Ferrosilicon
High-Capacity FeSi Production by HANI Metallurgy
Advancing the Standard of Ferroalloy Smelting
The Submerged Arc Furnace for Ferrosilicon is the core smelting equipment utilized in the production of various grades of ferrosilicon alloys. By maintaining a submerged arc state, where the electrode tips are buried deep within the quartz and coke mix, the SAF ferrosilicon unit ensures that the heat generated by the electric arc is efficiently transferred to the reaction zone. At HANI, we specialize in high-capacity smelting equipment that incorporates advanced electrode management and automated batching systems. Our Submerged Arc Furnace for Ferrosilicon is designed to provide stable, large-scale production while achieving record-high silicon recovery rates and low specific energy consumption.
Operating a Submerged Arc Furnace for Ferrosilicon requires precise control over the electrical and thermal characteristics of the hearth. HANI’s SAF ferrosilicon technology utilizes high-efficiency transformers and optimized short-net designs to minimize power loss. As a global leader in smelting equipment, HANI provides turnkey solutions that include everything from raw material preparation to final alloy tapping. Our Submerged Arc Furnace for Ferrosilicon is trusted by metallurgical plants worldwide for its durability and high operational uptime.

Advanced Smelting Control in HANI SAF
The HANI Submerged Arc Furnace for Ferrosilicon technology integrates advanced PLC and AI-driven control logic. In smelting equipment, the stable positioning of electrodes is critical for maintaining high power factors and optimal reaction rates in the SAF ferrosilicon hearth. Our intelligent control system automatically adjusts the electrode height and batching frequency based on real-time impedance measurements.
Furthermore, our smelting equipment features a patented “Rotary Shell” design. In a Submerged Arc Furnace for Ferrosilicon, the rotation of the shell ensures that the material is distributed evenly, preventing the formation of large “craters” and improving the recovery of silicon. Coupled with HANI’s high-efficiency water-cooling technology, our SAF ferrosilicon units provide a long-lasting and reliable smelting platform.
Production Reference Values for SAF Ferrosilicon
For the successful operation of a Submerged Arc Furnace for Ferrosilicon, HANI provides the following operational benchmarks:
- Specific Consumption: 7400-8000 kWh per ton of FeSi75 in our high-capacity smelting equipment.
- Electrode Consumption: 40-60 kg per ton of FeSi produced in the SAF ferrosilicon unit.
- Tapping Cycle: For a 33 MVA unit, tapping every 2 to 3 hours ensures stable furnace hearth health in smelting equipment operation.
Professional FAQ on SAF Smelting Equipment Technology
Q1: What is the typical life of a HANI Submerged Arc Furnace for Ferrosilicon lining?
A: With HANI’s high-quality carbon block hearth and proper water cooling, the lining of our SAF ferrosilicon units typically lasts 8-12 years in continuous smelting equipment operation.
Q2: How does the SAF ferrosilicon handle environmental standards?
A: Our Submerged Arc Furnace for Ferrosilicon is equipped with a high-capacity baghouse filter plant to capture 99.9% of silica fume, which can be reused in the construction industry, making our smelting equipment highly eco-friendly.
Q3: Can HANI’s smelting equipment be customized for different alloy grades?
A: Yes. The Submerged Arc Furnace for Ferrosilicon is highly flexible; by adjusting the ratio of quartz and iron scrap, you can easily produce FeSi45, FeSi65, FeSi72, or FeSi75 in the same SAF ferrosilicon unit.
