Abstract: A system and method for removing flatness faults from a metal flat product, in particular a metal sheet or a strip, having multiple straightening rollers arranged on opposite sides of the flat product. In order to simplify and to enable more cost-efficient removal of flatness faults from a metal flat product, at least two cooperating straightening rollers arranged on opposite sides of the flat product each have at least three individually-adjustable partial rollers arranged axially adjacent to one another.

Abstract: A strip deflector has a base body formed with a tip, a compressed-air chamber, and a nozzle for emitting compressed air. A compressed-air source in flow communication with the compressed-air chamber feeds compressed air to the compressed-air chamber and the nozzle. This nozzle has a first nozzle subpassage in flow communication with the compressed-air chamber and a second nozzle subpassage downstream of the first nozzle subpassage in a flow direction. The first nozzle subpassage is formed by a flank closer to the tip of the base body and an opposite flank remote from the tip of the base body, and, at a transition from the first nozzle subpassage to the second nozzle subpassage, the flank closer to the tip of the base body is bent away toward the tip of the base body so as to form a first separation edge.

Abstract: The invention relates to a method and a rolling stand (100) for cold rolling rolled stock. The rolling stand (100) comprises at least one upper and one lower backup roll (110-1, 110-2) and also an upper and a lower work roll (120-1, 120-2), which define a roll gap (128). Optionally, a lower and an upper intermediate roll (130-1, 130-2) may also be provided between the work rolls and the backup rolls. In order to ensure an absolutely equal circumferential speed of the upper and lower work rolls when cold rolling in skin-pass mode, it is proposed according to the invention to decouple the upper or lower work roll from its associated drive device.

Abstract: A modular rolling train, particularly a hot rolling train, preferably in conjunction with an upstream casting facility, and a method for operating a modular rolling train are described. The rolling train is standardized and modularized by dividing the rolling train into discrete units n and by modularization of the discrete units. The rolling train can be flexibly adapted to new requirements by exchanging a module.
