Copper Plate / Liner: Cooling Channel Diameter 8-15 mm

Component Specifications

Definition

A precisely engineered copper plate or liner component that forms the inner surface of water-cooled copper molds in continuous casting systems. It directly contacts molten metal during solidification, providing critical heat transfer, surface quality control, and dimensional accuracy for cast products.

Working Principle

The copper plate/liner functions as the primary heat exchange surface in water-cooled molds. Molten metal solidifies against its inner surface while cooling water circulates through channels behind it, extracting heat rapidly to form a solidified shell. The high thermal conductivity of copper ensures efficient heat transfer, while its precise surface finish controls the cast product's surface quality.

Materials

High-purity oxygen-free copper (C10100/C10200) or copper alloys with chromium-zirconium (C18150) for enhanced strength and thermal stability. Typical composition: Cu ≥99.95%, with controlled oxygen content ≤10 ppm for oxygen-free grades.

Frequently Asked Questions

Why is copper used for mold plates in continuous casting?

Copper offers exceptional thermal conductivity (second only to silver among common metals), allowing rapid heat extraction from molten metal. It also provides good machinability for precise surface finishes and reasonable durability under thermal cycling conditions.

How often do copper plates/liners need replacement?

Typical service life ranges from 6-24 months depending on operating conditions, casting material, and maintenance practices. Factors affecting lifespan include thermal fatigue, erosion from molten metal, and surface degradation from oxidation or coating wear.
