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).
