NC, headquartered in Yuncheng, Shanxi Province, China, is active in mining, smelting, and processing copper. The mill will roll C10200 and C11000 copper with an entry thickness of 0.3 mm, resulting in foil with thicknesses down to a minimum of 0.006 mm. Foils with widths varying from 350 to 660 mm can be processed at a maximum speed of 800 m/min. The maximum coil weight will be 3 t.
Primetals is responsible for engineering, manufacturing, and supplying the mechanical equipment and will supervise installation and commissioning. Likewise, the engineering, supply, and supervision of installation and commissioning of the electrical and automation equipment will be handled by Primetals. The X-Mill consists of non-segmented type non-split supporting rolls and has features to ensure best operational performance and simplified maintenance compared to 12HI and 20HI mills, which consist of many segmented supporting rolls.
Primetals already supplied nine sets of 6Hi cluster mill to several customers. In high demand for cooper foils for electronic devices for automobiles, Primetals is highly regarded as an unparalleled copper foil mill supplier to fulfill the need. The cluster mills (X-Mill) were developed by Primetals to realise smaller work roll diameters. The X-Mill with intelligent shape control using Automatic Flatness Control is designed for ultra-thin strip and 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 work roll top to prevent horizontal deflection. This enables stable and reliable thin-gauge rolling to be performed.
