Multi-Electrode DC Electric Arc Furnace for Vanadium-Titanium Slag Resource Recovery
This Multi-Electrode DC Electric Arc Furnace is a specialized smelting solution engineered for high-efficiency resource recovery from vanadium-titanium slag. Utilizing advanced multi-electrode DC arc technology, it achieves superior metal recovery rates and energy efficiency compared to conventional single-electrode or AC furnaces, making it the optimal choice for vanadium-titanium magnetite processing enterprises and metallurgical slag recycling operations.
Core Working Principle
The furnace employs three independently controlled DC graphite electrodes generating stable, high-energy-density plasma arcs between electrodes and the furnace bottom anode. The operating temperature reaches 1500-1700°C, ensuring complete melting of vanadium-titanium slag and efficient reduction of vanadium and iron oxides. With the addition of carbonaceous reductants and lime flux, vanadium-iron alloy settles at the furnace bottom while titanium-rich slag floats on the upper layer, enabling clean slag-metal separation.
Key Technical Advantages
Multi-Electrode DC Technology
- Triple Electrode Configuration: Three Φ400-500mm graphite electrodes with independent lifting and power control, eliminating arc deflection common in single-electrode DC furnaces.
- Uniform Heat Distribution: Multi-point arc discharge creates a balanced thermal field, reducing cold spots and improving melt homogeneity by 30% compared to single-electrode designs.
- Enhanced Electromagnetic Stirring: The multi-electrode arc interaction generates stronger molten pool stirring, accelerating reduction reactions and shortening smelting cycles by 15-20%.
Superior Resource Recovery
- Vanadium Recovery Rate ≥85%: Deep reduction environment ensures maximum vanadium extraction from complex vanadium-titanium slag matrices.
- Iron Recovery Rate ≥98%: Near-complete iron reduction transforms waste slag into valuable vanadium-iron alloy.
- Titanium Slag By-product: Titanium-enriched slag can be further processed for titanium dioxide production or utilized as high-grade refractory raw material.
Energy Efficiency & Environmental Performance
- Power Factor 0.95-0.98: No reactive power compensation required, reducing electrical infrastructure costs.
- 30% Lower Electrode Consumption: DC operation combined with optimized multi-electrode control reduces graphite electrode wear vs. AC furnaces.
- CO-rich Off-gas Utilization: High-temperature flue gas undergoes secondary combustion and waste heat recovery, reducing auxiliary energy consumption by 10-15%.
- Closed Flue Gas System: Integrated bag filter and desulfurization ensure compliance with EPA and EU emission standards (particulate matter ≤10mg/m³).
Intelligent Control & Reliable Operation
- PLC Full Automation: S7-1500 PLC with HMI touchscreen for real-time monitoring of current, voltage, temperature, and electrode position.
- Electrode Auto-Regulation: PID closed-loop control with German Parker proportional valves enables precise electrode height adjustment (±2mm).
- Multi-Point Bottom Temperature Monitoring: Real-time furnace bottom lining temperature detection with automatic alarm and power adjustment.
- Furnace Body Tilting: Hydraulic forward tilting up to 35° for complete alloy tapping and 15° for slag discharge.
