Reduction Iron Electric Furnace
Equipment Introduction & Technical Parameters
Reduction Iron Electric Furnace (also known as Direct Reduction Iron Electric Furnace, Smelting Reduction Furnace, Submerged Arc Reduction Furnace) is a key metallurgical equipment that uses electric energy as the heat source to reduce iron ore (or iron concentrate, pellets) into metallic iron (Direct Reduced Iron DRI / Sponge Iron or molten pig iron) at high temperatures.
Different from traditional blast furnaces, it does not require coke and mainly relies on carbonaceous reductants (coal/coke) and electric heat. It is widely used in electric furnace steelmaking, precision casting, etc.
1. Equipment Classification & Structure
1.1 Main Types
- Submerged Arc Reduction Furnace (Mineral Heat Furnace): The most mainstream type. Electrodes are buried in charge, heated by electric arc + resistance heat, closed/semi-closed, for large-scale continuous production.
- Smelting Reduction Furnace (e.g., SRV Furnace): Integrates prereduction and final reduction, directly producing liquid hot metal with high capacity.
- Shaft Furnace Type Reduction Electric Furnace: Gas-based + electric heating, producing solid sponge iron (DRI).
1.2 Main Components (Submerged Arc Type)
-
Power Supply System
- Furnace transformer (low voltage, high current, on-load voltage regulation)
- Short network, high/low voltage cabinet, reactive power compensation
-
Electrode System
- Soderberg / graphite electrode, electrode holder, lifting & slipping device
-
Furnace Body System
- Furnace shell (steel plate), furnace lining (carbon/magnesia refractory)
- Tap hole & slag hole
-
Auxiliary Systems
- Water cooling system
- Feeding system
- Flue gas purification & waste heat recovery
2. Working Principle
- Heat Source: Electric arc (3000–6000°C) + resistance heat in burden.
- Reduction Reactions:
- Process: Preheating → high-temperature reduction → slag-iron separation → tapping.
3. Typical Technical Parameters
3.1 Electrical Parameters
| Parameter | Range | Description |
|---|---|---|
| Transformer Capacity | 6,300 – 75,000 kVA | Higher capacity = higher output |
| Secondary Voltage | 80 – 290 V | Low voltage, high current |
| Secondary Current | 20,000 – 80,000 A | Phase current |
| Power Factor | ≥ 0.9 | With compensation |
3.2 Furnace & Electrode Parameters (33,000 kVA example)

- Electrodes: 3 pieces, triangular arrangement, Φ1.2–1.5 m
- Electrode circle diameter: 4.0–5.5 m
- Lining life: 3–7 years
3.3 Capacity & Consumption
- Daily output: 200–800 t/d
- Annual capacity: 60,000 – 250,000 t/y
- Power consumption: 2,400 – 3,800 kWh/t DRI
- Reductant: 450 – 650 kg/t
- Flux (lime/dolomite): 150 – 300 kg/t
4. Features & Advantages
- Flexible raw materials: Uses ore, pellets, coal; no coke required.
- High-quality product: Low S/P, high purity, ideal for EAF steelmaking.
- Short process, low pollution: No coking or sintering, lower CO₂ emissions.
- Stable control: Precise electric heating, stable temperature & atmosphere.
- Wide capacity range: From small (6,300 kVA) to large (75,000 kVA).
