Casting and rolling of aluminium strips in one continuous production process. The new Nexcast minimill produces strips of all kinds of aluminum and aluminum alloys, with sufficient surface quality for most applications, good to very good thickness-, profile- and flatness tolerances and very stable final rolling temperature over the strip body length.
influence the overall roll profile. It is common practice adjusting the roll cooling to the strip width being rolled. Roll cooling is hence an actuator to allow stable rolling conditions of the mill. This is particular true for strip tandem rolling mills with regard to steering the strip, ensuring it remains in the mill centre.
In the rolling process, the job is drawn through a set of rolls due to interface friction, and the compressive forces reduce the thickness of the workpiece or change its cross-sectional area.. The types of rolls used in rolling mills depend upon the shape, size, and gap between the rolls and their contour. Because of workability and limitations in …

The key issue of CVC system is the design principle of the CVC rolls profile. Previous researchers, such as Jiang et al. [8], designed a CVC roll with quintic curve to control quarter buckle.The third-order CVC roll profile is adapted widely in the hot and cold rolling mill because the centre buckle and edge buckle are the main shape defect.
As a WR profile control method for schedule-free rolling, the WR shifting method has been widely used to disperse roll wear and thermal crown in the axial direction of roll [3]. In hot rolling, the WR shift is mainly applied to the latter stands in …
