Copper Mold Plates / Tubes

Copper mold plates and tubes are critical components in continuous casting mold assemblies, designed to contain and shape molten metal (typically steel or non-ferrous alloys) as it solidifies into semi-finished products like slabs, blooms, or billets. These components feature high thermal conductivity copper alloys with precisely engineered cooling channels to extract heat efficiently, ensuring uniform solidification and surface quality. They operate under extreme thermal cycling and mechanical stress, requiring precise dimensional tolerances and surface finishes to prevent defects like cracks or sticking.

Copper mold plates/tubes work by transferring heat from molten metal to cooling water flowing through internal channels. The high thermal conductivity of copper alloys allows rapid heat extraction, causing the metal to solidify against the mold walls into the desired cross-sectional shape. Controlled cooling rates prevent thermal stresses and ensure a uniform solidification front, while lubricants or coatings may reduce friction and wear during strand withdrawal.
