Copper Plate Body: Plate Thickness 30-50 mm, Hardness 80-120 HB

Component Specifications

Definition

A precision-engineered copper plate component that forms the inner wall of continuous casting molds in steelmaking, designed to extract heat from molten steel to initiate solidification while maintaining dimensional stability and surface quality of the cast product.

Working Principle

The copper plate body functions as a primary cooling surface in continuous casting molds. Molten steel flows through the mold cavity formed by these plates, where heat transfer through the copper initiates solidification of a thin shell. The plate's high thermal conductivity allows rapid heat extraction, while its geometry and surface treatment ensure uniform cooling and minimal friction with the solidifying steel strand.

Materials

High-purity oxygen-free copper (C10100/C10200) or copper alloys with silver/chromium additions (C18200/C18150) for enhanced strength and thermal stability; surface often coated with nickel or chrome plating for wear resistance.

Frequently Asked Questions

Why is copper used for continuous casting mold plates?

Copper offers exceptional thermal conductivity (second only to silver among pure metals), allowing rapid heat extraction from molten steel to form a solid shell quickly, while maintaining mechanical stability at high temperatures.

How often do copper plates need replacement?

Typical service life is 200,000-500,000 tons of cast steel, depending on operating conditions, maintenance practices, and whether protective coatings are applied. Regular inspection for wear, cracks, and thermal distortion is essential.
