Water Jacket / Cooling Channel System: Channel Diameter 8-20 mm

Component Specifications

Definition

The Water Jacket / Cooling Channel System is an engineered assembly integrated into water-cooled copper molds, typically used in continuous casting machines for steel, aluminum, and other non-ferrous metals. It consists of precisely machined internal channels or external jackets that circulate cooling water to extract heat from the molten metal, controlling the solidification rate and preventing defects like cracks or uneven microstructure. This system is essential for maintaining mold integrity, extending service life, and ensuring consistent product quality in high-temperature industrial applications.

Working Principle

The system operates on convective heat transfer principles. Cooling water is pumped through channels or jackets in direct contact with the copper mold walls. As molten metal solidifies against the mold surface, heat is absorbed by the water, which carries it away. This continuous circulation maintains a stable temperature gradient, promoting controlled solidification and minimizing thermal stress on both the mold and the cast product.

Materials

Primary: High-conductivity copper alloys (e.g., CuCrZr, CuAg) for mold body; Cooling channels: Stainless steel (e.g., 316L) or copper tubing; Seals: High-temperature resistant elastomers (e.g., Viton); Connectors: Brass or stainless steel fittings.
