Copper-Cobalt Alloy Furnace

Product Overview

1. Main Equipment Composition

1. Full Water-Cooled Tilting Furnace Body

   
   

   Split/integral steel shell with full water-cooled wall + magnesia-chromium refractory lining, resisting temperatures up to 1600℃ and acid-base slag erosion. Tilting angle: 0–45° (alloy tapping), 0–15° (slag removal), driven by a hydraulic system for stable operation.
   
   
2. Water-Cooled Furnace Roof & Electrode System

   
   

   Annular full water-cooled roof with central electrode hole and side dust removal/charging ports for sealing and heat preservation. Φ300–Φ500mm graphite electrodes with servo hydraulic lifting (0.8–1.5m/min) ensure stable arc and sensitive adjustment.
   
   
3. Transformer & Short-Net System

   
   

   Energy-saving dedicated transformer (2000–8000kVA), high voltage: 35kV, low voltage: 180–300V. Low-impedance short net + full water-cooled conductive cross arm minimizes high-current transmission loss and improves thermal efficiency.
   
   
4. Charging & Slag Tapping Mechanism

   
   

   Automatic top/side charging bin for mixed materials (ore, coke, lime). Trough/EBT alloy tapping ensures smooth outflow with minimal residual slag, paired with ladles for rapid transfer.
   
   
5. PLC Intelligent Control System

   
   

   Dual automatic/manual mode with one-key start-stop, automatic arc stabilization, and closed-loop temperature/power control. Supports online composition monitoring, data logging, and remote monitoring with full interlock protection for safety.
   
   
6. Auxiliary Systems

   
   

   Closed circulating water cooling, baghouse dust removal (emission ≤10mg/m³), automatic coke/lime conveying, hydraulic station, and lubrication systems. Fully equipped and environmentally compliant.
   
   

2. Core Performance Advantages

• High Recovery Rate: Precise temperature control (1400–1600℃) ensures complete reduction, with Cu recovery ≥86% and Co recovery ≥90%.
• Superior Alloy Quality: Optimized slag system (CaO/SiO₂=1.0–1.3) minimizes impurities (Fe, Si, S), delivering Cu+Co≥40% with uniform composition.
• High Efficiency & Low Consumption: Full water-cooled design reduces refractory consumption (2x longer life). Single-furnace cycle: 50–90min, power consumption: 2200–3200kWh/t alloy.
• High Temperature Resistance & Long Service Life: Water-cooling + refractory double protection minimizes deformation and erosion for extended continuous operation.
• Eco-Friendly & Safe: Closed smoke extraction + high-efficiency dust removal eliminates leaks. Full interlock protection prevents overheating and leakage.
• Wide Raw Material Adaptability: Compatible with oxide/sulfide copper-cobalt ores, copper-cobalt slag, and recycled materials for flexible production.
