Copper cold rolling mills

Cold Rolling
Great past, brilliant future – solutions for efficient copper cold rolling

The first metal ever used by humans comes with special properties that make it particularly valuable and almost universally useful. Undeniably, without copper there would be no modern renewable energies, cars, computers, or smartphones. However, copper has become scarcer on the global market. That’s why copper strip and plate manufacturers are keen to save every gram. They need rolling mills which achieve a low rate of rejects, reliably high productivity, plus consistently high precision and quality. All this goes into our plants and know-how to ensure you can produce high-quality copper and semi-finished goods. Depending on the product range, for instance cooper, brass or bronze, and the required annual capacity, SMS group develops and erects the right mill type for roughing, intermediate and finish rolling. Included here are reversing and tandem mills in 4-high, 6-high or 20-high (only reversing mills) design.

Concepts

Up to the limit

Maximum utilization of valuable material in every process step

The material requirements of copper and copper alloys, including brass, bronze, and ever more new materials, are what determines the design of a cold rolling mill. It depends on your product mix and its required capacity whether the best solution is a tandem non-reversing or a reversing cold mill. SMS group offers you CVC® plus 4-high, CVC® plus-6-high, and 20-high stand designs. Furthermore, we provide optimal mill solutions for all your rolling tasks. Typical processes are roughing, roughing and intermediate rolling in one mill, intermediate and finish rolling in one mill, and finish rolling.
