A cassette intended to be provided on a rolling mill, the cassette (1) forming a self-supporting unit including: a roller intended to constitute one of the two intermediate rollers of the rolling mill; two chocks (3) whereon are mounted the ends of the roller (2); at least one support arm (4) of the at least one side bearing member the support arm extending between the two chocks and being mounted pivotingly in relation thereto. The cassette includes at least one pair of support elements (5) receiving the ends of a rotating shaft (6) of the at least one support arm and the two support elements being detachably fastened, respectively, on the two chocks so as to allow the disassembly of the at least one support arm of the chocks and/or the assembly of the at least one support arm on the chocks independently of the disassembly/assembly of the roller.

A substrate (e.g., metal or non-metal sheet) can have multiple textures on a surface of the substrate. The various textures can be impressed or applied on the surface of the substrate by passing the substrate between multiple pairs of work rolls that each include at least one textured work roll for transferring a texture of the work roll onto the surface of the substrate. The pairs of work rolls apply the various textures on the surface of the substrate while maintaining a thickness of the substrate (e.g., with substantially no reduction in a thickness of the substrate). A single pass of the substrate between the pairs of work rolls can allow various different textures, patterns, or features to be applied to the surface of the substrate while the thickness of the substrate remains substantially constant.

Systems and methods of applying a texture on a substrate include applying a texture to the substrate with a work stand of a coil-to-coil process. The work stand includes an upper work roll and a lower work roll vertically aligned with the upper work roll. At least one of the upper work roll and the lower work roll includes the texture. Applying the texture includes applying, by the upper work roll and a lower work roll, a work roll pressure on an upper surface and a lower surface of the substrate. The method further includes adjusting a contact pressure parameter of the work stand such that the work stand provides a desired contact pressure distribution across the width of the substrate and a desired thickness profile of the edges of the substrate while an overall thickness of the substrate remains substantially constant.

A flatness control system includes a work stand of a finishing line, a plurality of actuators, a flatness measuring device, and a controller. The work stand includes a pair of vertically aligned work rolls. A first work roll of the pair of work rolls includes a plurality of flatness control zones configured to apply a localized pressure to a corresponding region on a substrate. Each actuator corresponds with a one of the plurality of flatness control zones. The flatness measuring device is configured to measure an actual flatness profile of the substrate. The controller is configured to adjust the plurality of actuators such that the localized pressures modify the actual flatness profile to achieve the desired flatness profile at the exit of the stand. The thickness and a length of the substrate remain substantially constant when the substrate exits the work stand.

Rolling mill (1) includes: side bearing rollers (5), able to laterally support the working rollers (2) of the rolling mill, with each side bearing roller being carried by a support arm (6), mounted pivoting on an axis (7), load distribution beams (8) extending between the corresponding posts of each pair, and elements (9) for applying a preload force on each support arm (6), intended to engage with one of the support arms on a bearing surface (10), and including at least one preload cylinder (11) integral with one of the load distribution beams (8), one or several spraying nozzles for a lubricant/cooling fluid, at least one of the nozzles (12, 12), is embedded on one of the support arms (6) and the fluid supply circuit of the at least one nozzle (12, 12) includes a connection/disconnection device (13) with the support arm (6).

A rolling mill (100) includes: a rolling-mill cage (10) containing a plurality of cylinders, including two working cylinders (12) and two pairs of intermediate cylinders (13), a main gate (30) on the front face of the rolling mill (100) for accessing all the cylinders, a device (20) for the lateral movement of the intermediate cylinders (13) of the push-push type including first and second pairs of hydraulic actuators (22, 22, 21, 21) each configured so as to exert a thrust force (P) to allow a lateral movement of the intermediate cylinders (13), a removable small gate (40) fixed to the main gate (30), allowing access to the cylinders (12) and (13), and integrating the second pair of hydraulic actuators (21, 21) so that opening and closing the small gate (40) does not interfere with the opening and closing of the main gate (30).
