製品の説明
Introduction to Medium‑Low Carbon Ferromanganese Furnace
Medium‑low carbon ferromanganese (FeMn) furnaces are specialized submerged‑arc refining furnaces designed to produce medium‑carbon ferromanganese (MC‑FeMn, C ≤ 2.0%) and low‑carbon ferromanganese (LC‑FeMn, C ≤ 0.7%). They are core equipment for high‑purity ferroalloy production, widely used in high‑grade steelmaking (e.g., HSLA steel, stainless steel) to provide deoxidation, desulfurization, and alloying with controlled carbon.
1. Working Principle
The furnace operates on the silicothermic reduction & decarburization refining principle:
- Raw materials (manganese ore, silicomanganese alloy, high‑carbon ferromanganese, lime) are melted under submerged arc heating.
- Silicon in silicomanganese reduces manganese oxides; oxygen blowing or slag‑metal reactions oxidize excess carbon and impurities (Si, P) into slag.
- Strong electromagnetic stirring ensures uniform composition and efficient refining, yielding low‑carbon, high‑purity FeMn.
2. Main Structure
- Furnace Body: Cylindrical steel shell with high‑purity MgO‑C refractory lining (MgO > 85%) to resist high temperature and slag erosion.
- Electrode System: 3 graphite electrodes (φ400–600 mm) with automatic lifting; powered by a dedicated furnace transformer.
- Tilting Mechanism: Hydraulic tilting (max 45° for tapping, 15° for slagging) with 1°/s tilting speed.
- Power Supply: Rectifier‑transformer unit (3,000–10,000 kVA) providing stable submerged arc heating.
- Auxiliary Systems: Bottom gas stirring, top oxygen blowing, dust collection, and PLC‑based automatic control.

| Low‑Carbon FeMn | 80–85 | ≤0.7 | ≤1.5 | ≤0.10 | ≤0.02 |
5. Key Advantages
- High Purity: Low carbon and impurity levels meet strict steelmaking standards.
- High Efficiency: Short smelting cycle, high manganese yield (>90%).
- Low Consumption: Optimized power and raw material usage; advanced furnaces reach ≤600 kWh/t文山壮族苗族自治州人民政府.
- Stable Operation: PLC control ensures consistent quality and low electrode consumption.
- Environmental Friendly: Efficient dust collection and waste heat recovery reduce emissions.
6. Typical Smelting Process
- Pre‑treatment: Furnace patching, raw material preparation & drying.
- Charging: Batch feeding of manganese ore, silicomanganese, lime, and high‑carbon FeMn.
- Melting & Reduction: Submerged arc heating melts charge; silicon reduces MnO.
- Decarburization & Refining: Oxygen blowing and slag adjustment remove C, Si, P.
- Tapping & Casting: Tilt furnace to tap; cast into ingots or granules.
7. Application
- Steelmaking: Additive for HSLA steel, stainless steel, bearing steel, and die steel to improve strength, toughness, and corrosion resistance.
- Foundry: Enhances hardness and wear resistance in cast iron.
