Continuous Casting Mold Copper Plate

Product Specifications

Technical details and manufacturing context for Continuous Casting Mold Copper Plate

Definition

A continuous casting mold copper plate is a critical consumable component in continuous casting machines, where it directly contacts molten steel to initiate solidification. It forms the outer shell of the steel strand through rapid heat extraction via internal water channels. These plates are essential for maintaining casting speed, strand quality, and operational stability in steel production. They represent a high-wear component requiring precise metallurgical properties and cooling efficiency.

Typical specifications include a plate thickness of 20–60 mm, cooling channel diameter of 6–12 mm, and cooling channel pitch of 15–30 mm. The copper alloy is typically CuCrZr, with a Brinell hardness of 80–120 HB (ASTM E10). Maximum operating temperature ranges from 250–350 °C, and water flow rate capacity is 100–300 m³/h. Plate dimensions vary with caster width and strand size: length 800–2500 mm, width 200–600 mm, and weight per plate 100–500 kg. Flatness tolerance is ≤0.05 mm (ISO 1101), and surface roughness is Ra 0.8–1.6 μm (ISO 4287).

These values are directory reference ranges and must be confirmed for the specific model and application. The plate is typically backed by stainless steel for structural support. Verification questions should address material certification, dimensional tolerances, and cooling channel integrity. Maintenance signals include surface wear, cracking, or reduced cooling efficiency. Failure boundaries include excessive deformation or blockage of cooling channels, which can lead to strand breakouts. Always verify model-specific values and standards with the legal manufacturer or supplier.

Working Principle

Molten steel flows against the copper plate surface, transferring heat through the plate to internal cooling water, forming a solidified shell that maintains strand shape while moving through the casting machine. The cooling water circulates through channels inside the plate, absorbing heat and maintaining the plate temperature within safe limits. The solidified shell thickens as the strand progresses, and the plate's surface quality and cooling uniformity directly influence the strand's surface and internal quality.
