Copper Cold Rolling and Copper Foil Rolling Mill

Primetals Technologies provides solutions that address the growing market demand and trends for rolled copper and copper alloy sheet and foil. The appropriate mill configuration is essential for meeting diverse quality, productivity, and characteristic requirements. The extensive copper rolling and copper foil rolling portfolio from Primetals Technologies includes the cluster type mill (6/10-high, 12-high, 20-high), 4-high conventional mill, and 6-high Universal Crown Control Mill (UC-MILL). These configurations meet any customer requirement and enable the effective production of high-quality copper sheet and copper foil with tight tolerance specifications.

UC-Mill for Copper Rolling

The UC-MILL for copper rolling and copper alloys features small work rolls (WR) combined with shape control functions consisting of WR bending, intermediate roll (IMR) bending, IMR shift using all straight uncambered rolls, and a spot cooling system. The UC-MILL enables hard and thin copper rolling with excellent shape control. Furthermore, equipped with a cobble guard and air wiping system at the mill exit side, proficient wiping ability can be achieved during high-speed copper rolling.

X-Mill for Copper Rolling

The X-Mill has intelligent shape control and is designed for ultra-thin copper foil rolling. The rolls are arranged in an X configuration, with parallel backup rolls supporting each side of the small diameter work rolls to prevent horizontal deflection. The parallel backup rolls and prevention of horizontal deflection enable stable and reliable thin-gauge copper rolling.
