Technical details and manufacturing context for Water-Cooled Copper Mold

Definition
A critical component in the continuous casting system of integrated steelmaking, the water-cooled copper mold receives molten steel from the tundish and initiates solidification through rapid heat extraction via internal water circulation. It forms the initial solidified shell that maintains the desired cross-section (e.g., slab, bloom, billet) as the strand moves downward, ensuring dimensional accuracy and surface quality before entering the secondary cooling zone.
Working Principle
Molten steel flows into the mold cavity from the tundish. Copper's high thermal conductivity, combined with pressurized water circulating through channels within the mold walls, rapidly extracts heat from the steel. This causes a thin, solidified shell to form against the mold walls. The shell thickens as it descends, supported by the mold until it is strong enough to exit and enter secondary cooling. Oscillation of the mold prevents sticking and facilitates smooth strand withdrawal.
Common Materials
Copper (often with chromium or silver alloying), Stainless Steel (for structural components/backplate)
Technical Parameters
  • Mold internal dimensions (width, thickness) defining the final product cross-section (e.g., slab: 1500x250mm). (mm) Standard Spec
Components / BOM
  • Copper Plate / Liner
    Forms the primary heat-transfer surface in contact with molten steel. Contains water channels.
    Material: Copper alloy (e.g., CuCrZr, CuAg)
  • Water Jacket / Cooling Channel System
    Network of machined passages within the copper plate for pressurized water circulation.
    Material: Integral to copper plate
  • Mold Backplate / Support Structure
    Provides structural rigidity, houses water inlet/outlet manifolds, and attaches to the oscillator.
    Material: Stainless steel
  • Water Inlet/Outlet Manifolds
    Distribute and collect cooling water to/from the channel system.
    Material: Stainless steel
Engineering Reasoning
0.8-2.5 MPa (8-25 bar) water pressure, 15-35°C inlet temperature, 0.5-3.0 m/s water velocity
Copper temperature exceeds 350°C (recrystallization threshold), water pressure drops below 0.5 MPa (5 bar) causing flow separation, thermal gradient exceeds 200°C/cm across mold wall
Design Rationale: Thermal fatigue from cyclic stress (Δσ > 150 MPa) due to 1200°C molten steel contact alternating with 30°C cooling water, causing crack initiation at grain boundaries; cavitation erosion when local pressure drops below water vapor pressure (2.34 kPa at 20°C) in high-velocity zones
Risk Mitigation (FMEA)
Trigger Calcium aluminosilicate inclusion buildup (0.1-0.5 mm thickness) on copper surface
Mode: Thermal resistance increase (0.001-0.005 m²·K/W) causing local copper temperature rise to 400°C
Strategy: Periodic electromagnetic stirring (50-100 Hz, 0.1-0.3 T) to prevent inclusion adhesion, mold powder optimization (viscosity 0.1-0.3 Pa·s at 1300°C)
Trigger Water channel scaling (CaCO₃ deposition > 0.2 mm thickness) reducing heat transfer coefficient by 15-30%
Mode: Localized boiling at copper-water interface creating vapor blanket (thermal conductivity 0.02 W/m·K vs water's 0.6 W/m·K)
Strategy: Deionized water treatment (conductivity < 5 μS/cm), periodic citric acid cleaning (3-5% concentration, 50-60°C, 4-6 hour cycles)
