Product Description

Energy-saving Ladle Refining Furnace (LRF/LF) with water cooling system is a high-efficiency secondary refining equipment in modern steelmaking, integrating advanced water-cooled components and intelligent control to drastically cut power consumption, extend equipment life, and improve steel quality.

Core Structure & Water-Cooled Components

Water-Cooled Furnace Lid/Roof

Design: Full tubular water-cooled structure (seamless steel pipes 20g/Q345R), labyrinth/spiral channels, no dead zones.
Cooling: Closed-loop softened water (conductivity <100μS/cm, pH 7.5–8.5), ΔT ≤8°C.
Benefits: Surface temp <60°C, minimal thermal deformation, extends refractory life, reduces heat loss by ~30%.
Water-Cooled Conductive Arm & Electrode System
- Copper-steel composite conductive arm with internal water cooling.
- Water-cooled cable/large cross-section busbar reduces impedance and heat loss.
- Energy saving: Lower main circuit resistance → 10–15% less electricity.
- 1. Water-Cooled Short Network & Transformer
    - Cools high-current components (busbars, transformer coils).
    - Stabilizes electrical parameters, improves power factor (to ~0.95), cuts reactive power loss.
  2. Integrated Water Cooling System (Closed Loop)
    - Components: Plate heat exchanger, variable-frequency cooling tower, VFD pumps, online water quality monitoring (TDS, turbidity, Fe²⁺).
    - Control: PLC-based automatic flow/temp/pressure regulation; flow fluctuation <±3%.
    - Safety: Backup water supply, over-temperature/under-flow alarms.
  Key Energy-Saving Mechanisms
  1. Reduced Thermal Loss
    - Efficient water cooling lowers shell/roof heat radiation → heat loss reduced by 25–40%.
    - Maintains higher furnace thermal efficiency, less arc power wasted.
  2. Optimized Electrical Efficiency
    - Low-impedance water-cooled conductors → higher thermal efficiency.
    - Stable arc → reduced electrode consumption (15–20%).
  3. Intelligent Variable-Frequency Operation
    - VFD pumps/fans: match flow to heat load → pump power down 20–30%.
    - Smart control stabilizes water temp ΔT at optimal 4–8°C.
  4. Waste Heat Recovery (Optional)
    - Recover heat from cooling water for preheating boiler feedwater or workshop heating.
    - Improves overall energy utilization by 8–12%.
  Performance Advantages
  - Power consumption: ~20–30% lower than conventional LF.
  - Refractory life: extended by ~40%.
  - Productivity: shorter refining time, higher tapping accuracy.
  - Steel quality: better desulfurization/degassing/cleanliness.
  - Environmental: less radiation, lower dust emissions.
  Typical Technical Specifications
  - Capacity: 20–150 t
  - Rated power: 3–15 MW
  - Cooling water flow: 50–150 m³/h (furnace lid)
  - Inlet water temp: ≤35°C; Outlet ≤43°C
  - Water pressure: 0.4–0.6 MPa
  - Power factor: ≥0.92
  Summary
  
  This energy-saving LF with advanced water cooling is a high-efficiency, low-consumption, long-life refining solution. It cuts energy use, stabilizes production, and improves steel quality—ideal for high-grade steel production (bearing, alloy, stainless steels).
