In CCR lines, rollers are critical components utilized in both casting machines and rolling mills. They continuously shape, reduce, and work-harden molten copper or aluminum as it solidifies, transforming it into high-quality metal rods.

Hardened steel is selected for CCR rollers to withstand the extreme thermal stress of molten metal, high pressure during deformation, and mechanical wear, ensuring long-term operational durability and consistent output quality.

Two-roll configurations exert pressure from two opposing sides, whereas three-roll configurations apply force from three directions. Three-roll setups typically provide more uniform deformation, better surface finish, and higher reduction efficiency for metal rods.

As the metal passes through successive rolling stands, the mechanical compression forces recrystallization and grain refinement. This physical deformation increases the tensile strength and hardness of the resulting copper or aluminum rods.

Yes, rollers are designed for both copper and aluminum CCR lines. However, because copper has a higher melting point and greater hardness than aluminum, the specific steel grade, surface treatment, and cooling configuration of the rollers may be adjusted accordingly.
