Ferromanganese Refining Furnace

Product Overview

1. Main Equipment Composition

1. Tilting Furnace Body

   
   

   Split/integral furnace shell with full water-cooled wall + thickened magnesia refractory lining, resisting high temperature, erosion, and deformation. The furnace body supports 0–42° tapping tilting and 0–15° slagging tilting, adapting to refining processes flexibly.
   
   
2. Water-Cooled Furnace Roof & Electrode System

   
   

   Annular full water-cooled roof with central electrode hole and side dust removal interface for sealing and heat preservation. Φ350–Φ550mm graphite electrodes with servo hydraulic lifting (speed: 1.0–1.6m/min) ensure sensitive adjustment and stable arc.
   
   
3. Conductive & Short-Net System

   
   

   Full water-cooled conductive cross arm + low-impedance short net for stable high-current transmission and low energy consumption. Transformer capacity: 1500–6500kVA, high voltage: 35kV, low voltage: 165–285V, meeting diverse power demands.
   
   
4. Tilting & Tapping Mechanism

   
   

   Hydraulic tilting drive with tapping speed 0–0.6°/s and reset speed 0–1.0°/s. Equipped with EBT/trough tapping for smooth tapping and minimal residual slag, adapting to full-process automation.
   
   
5. PLC Intelligent Control System

   
   

   Dual automatic/manual mode with one-key start-stop, automatic arc stabilization, and online composition monitoring. Full interlock protection enables precise closed-loop control of temperature, composition, and power.
   
   
6. Auxiliary Systems

   
   

   Closed circulating water cooling, baghouse dust removal & flue gas, oxygen/carbon injection, hydraulic station, and grease lubrication systems. Fully equipped and environmentally compliant.
   
   

2. Core Performance Advantages

• High Refining Efficiency: High-temperature arc + slag stirring accelerates desiliconization and decarburization. Single-furnace cycle: 40–90min, capacity increased by 30%+.
• Superior Product Quality: Precise temperature control (1450–1650℃) and high-basicity slag (CaO/SiO₂=1.2–1.5) ensure Mn recovery ≥95% and controlled impurities (Si, C, P, S).
• Significant Energy Saving: Full water-cooled structure reduces refractory consumption (2–3x longer life). Power consumption: 2000–3000kWh/t alloy, low operation cost.
• Eco-Friendly & Safe: Closed smoke extraction + high-efficiency dust removal (dust emission ≤10mg/m³). Full interlock protection prevents steel leakage and overheating.
• Strong Adaptability: Compatible with high-carbon ferromanganese, silicomanganese, manganese-rich slag, etc. Flexibly produces medium-carbon (1.0–2.0%C), low-carbon (0.5–1.0%C), micro-carbon (≤0.5%C) ferromanganese.
