DEMcold rolling line produces thin copper strips

A manufacturer of electro-conductors in North America successfully started-up and commissioned a complete cold rolling line for the production of non-ferrous metals supplied by DEM Wire Rolling Technology of Italy. The line is aimed at the fabrication of extreme purity, high-conductivity copper strips in ETP or OF grades then used for the fabrication of PV ribbons as well as clad bus bars. The rationale for this project is the achievement of an increased output rate while keeping a constant tolerance on size; altogether avoiding the use of slit materials. The product mix includes end products having a minimum thickness of 0.009" and maximum width of approximately 0.5". The correct geometry is assured by an in-line laser measurement looped to the line

This is a state-of-the-art automated solution developed to grant near-zero downtimes. The premium quality of strip winding leading to coreless coils with right angle between barrel and flange sides while keeping superb roundness eases logistics and downstream operations whatever the final strip destination. With these provisions, the customer is operating one of the most avant-garde mills for strip production in the world. The line consists of pay-off facilities, flattening rolling stands, edging stands, dancers, cooling facilities, wiping device, in-line laser measurement and coiler with automatic unloading facilities. DEM acted as a system integrator supplying all the electric equipment, controls and software for line automation. The supervision to commissioning of the line and training of the customer’s personnel were also included in DEM’s scope of supply.
