Cooling Water Channels: Cooling Capacity 15-40 MW/m²

Component Specifications

Definition

Cooling water channels are precisely engineered internal passages integrated into continuous casting mold copper plates. These channels circulate cooling water to extract heat from the molten steel during the solidification process, maintaining optimal mold temperature, preventing thermal stress, and ensuring uniform shell formation in continuous casting operations.

Working Principle

Cooling water is pumped through these internal channels at controlled flow rates and pressures. As the water circulates, it absorbs heat from the copper plate that contacts the molten steel, transferring thermal energy away from the solidification front. This maintains a stable temperature gradient, promotes uniform solidification, and prevents copper plate overheating or thermal fatigue.

Materials

Copper alloys (typically Cu-Cr-Zr or Cu-Ag) with high thermal conductivity and strength; channel surfaces may have corrosion-resistant coatings.
