Slab crystallizer copper plates are used in continuous casting for producing wide steel slabs destined for plate mills, pipe manufacturing, and heavy plate applications. They handle high casting speeds while preventing breakouts through precise heat extraction. Steel industries rely on these plates for efficient slab formation in integrated mills and specialty steel plants.
Slab crystallizer copper plate specifications include widths of 900-2200 mm, thicknesses of 25-40 mm, and lengths around 800-1200 mm, often with funnel-shaped upper sections for thin slabs. Materials feature Cu-Ag or Cu-Cr-Zr alloys for thermal conductivity over 350 W/mK and strength. Custom tapers, chrome coatings, and cooling channels optimize performance for specific slab dimensions.
Slab crystallizer copper plates provide excellent heat transfer, enabling higher speeds, reduced cracks, and longer campaigns up to 10+ hours. Their durability cuts maintenance and boosts yield in demanding conditions. Ideal for steel producers in construction, energy, and automotive sectors needing consistent slab quality.
