COPPER/COPPER ALLOY COLD AND FOIL ROLLING MILL
The most advanced copper and copper alloy rolling mills in the world enable producers to achieve the highest quality and quantities.
Primetals Technologies offers solutions that satisfy increasing market demand for and trends toward rolled copper and copper alloy sheet/foil. The appropriate mill configuration is crucial for meeting various quality, productivity, and characteristic requirements. Primetals Technologies’ extensive portfolio 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), meeting any customer requirement, and enabling the effective production of high-quality sheet/foil to tight tolerance requirements.
Excellent shape control and high productivity
UC-Mill
The UC-MILL for copper 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 the rolling of hard and thin material with excellent shape control. Furthermore, equipped with a cobble guard and air wiping system at the mill exit, side and good wiping ability can be achieved during high-speed rolling.
X-Mill
The X-Mill with intelligent shape control is designed for ultra-thin foil rolling. The rolls are arranged in an X configuration in which a pair of parallel back-up rolls support each side of the small diameter work rolls at a tangent below the WR top to prevent horizontal deflection. This enables stable and reliable thin-gauge rolling to be performed.
Features:
- Compact and simple mill arrangement

Reference Story: High-productivity copper/copper alloy rolling mill
Customer:
Chinalco Shanghai Copper, China
Type of Plant:
Reversing Foil Mill for ultra-thin copper foil.
Our Solution:
This X mill with Air Bearing Shape Meter (ABSM) and hot spot spray is first application in China. 6-micron thickness was achived early in the commissioning stage. This is the first copper foil mill to start commmercial production with 10 microns or less in China.
