Crystallizer copper plates are used in continuous casting to form the wide faces of steel slabs or billets, facilitating rapid cooling while maintaining dimensional accuracy. Their role is crucial in industries like construction, automotive, and heavy machinery, where consistent quality and productivity in slab or billet production are required.
These copper plates come in a variety of sizes depending on caster design, typically ranging in width from 900 mm to over 2200 mm and thicknesses of 25 to 50 mm. They are made from high-conductivity copper alloys such as Cu-Cr-Zr or Cu-Ag for superior thermal performance and mechanical strength. Surface treatments like chrome plating improve wear resistance and extend service life.
Crystallizer copper plates provide excellent heat transfer, enabling faster casting speeds and reduced defects like surface cracks and segregation. Their durable alloys and optimized design extend operational life and reduce maintenance costs, making them indispensable for modern high-volume steel production. This enhances energy efficiency and product consistency in demanding casting environments.
