| System | Key Components & Specifications |
|---|---|
| Electrode System | 6 graphite/self-baking electrodes arranged in a regular hexagon; diameter 1000–1400mm; independent lifting & current adjustment mechanism for each electrode |
| Power Supply System | Thyristor rectifier transformer (split-type design: 2–3 rectifier cabinets in parallel); DC reactor; short-net with low-resistance copper busbar; rated power 80–150MVA |
| Furnace Body Structure | Steel shell + multi-layer refractory lining (corundum-magnesia brick + carbon ramming mass); conductive furnace bottom anode (graphite-carbon brick + copper conductive layer) to bear high current density (≤5A/cm²); furnace capacity 150–500t |
| Auxiliary Systems | High-flow cooling water system; PLC + DCS intelligent control system; closed-loop dust removal system; automatic quantitative feeding system |
| Parameter Index | Specification Range |
|---|---|
| Rated Power | 80–150MVA |
| Total Rated DC Current | 60–125kA (10–21kA per electrode, independently adjustable) |
| DC Input Voltage | 1000–1500V |
| Single Electrode Diameter | 1000–1400mm |
| Furnace Nominal Capacity | 150–500t (batch smelting for ferroalloy) |
| Smelting Temperature | 1900–2300℃ |
| Power Consumption | 3600–4500kWh/t (industrial silicon); 2800–3500kWh/t (high-carbon ferrochrome) |
| Electrode Consumption | 0.4–0.8kg/t (20% lower than four-electrode DC furnaces) |
| Cooling Water System | Total flow rate 800–1500m³/h; water pressure 0.45–0.65MPa; conductivity ≤50μS/cm |
| Dust Removal Efficiency | ≥99.8%; emission concentration ≤5mg/m³ |
| Electromagnetic Stirring Intensity | 1.2–1.8T (magnetic induction intensity) |
| Lining Service Life | 3–5 years (for ferroalloy smelting) |
| Advantage | Detailed Description |
|---|---|
| Uniform Current & Temperature Distribution | Hexagonal electrode layout eliminates local hot spots in the molten pool; temperature difference within the furnace ≤50℃, ensuring consistent product composition |
| Higher Power Density & Smelting Efficiency | Supports ultra-high power input (up to 150MVA); smelting cycle shortened by 15–20% compared to four-electrode furnaces; hourly output increased by 20–30% |
| Lower Energy & Electrode Consumption | Symmetric electromagnetic field reduces arc energy loss; power consumption reduced by 8–12%; independent electrode current control avoids over-burning of single electrodes, cutting consumption by 20% |
| Stronger System Stability | Split-type power supply design: if one rectifier cabinet fails, the others can continue operating (load rate ≥60%); low voltage fluctuation (≤±5%), friendly to the power grid |
| Better Scalability | Modular electrode and power supply design allows step-by-step capacity expansion (e.g., upgrading from 80MVA to 150MVA without replacing the furnace body) |
| Feature | Six-Electrode Large DC Submerged Arc Furnace | Four-Electrode DC Submerged Arc Furnace |
|---|---|---|
| Electrode Layout | Regular hexagon (symmetric) | Square (asymmetric local current) |
| Max Rated Power | 150MVA | 63MVA |
| Temperature Uniformity | ≤50℃ difference | 80–120℃ difference |
| Power Consumption | 3600–4500kWh/t | 3800–4800kWh/t |
| Hourly Output | 20–30% higher | Standard output |
| Retrofit Cost | High (new furnace body required) | Medium (retrofit from AC furnaces feasible) |
| Applicable Scale | Ultra-large (≥100,000t/year) | Medium-large (30,000–100,000t/year) |
