    Abstract: A method and a corresponding computer program product calculate a pass schedule for a stable rolling process when rolling metal strip in a rolling mill. The offset here is varied until the calculated target horizontal force satisfies a predefined limit criterion. The satisfaction of the limit criterion means that the set of rolls and the rolling process are stable. For cases in which a sole iteration of the offset of the working roll does not result in the limit criterion being satisfied, the present invention provides that the draws on the material to be rolled are then changed on the feed side and/or on the outlet side of the rolling stand with constant offset until the calculated target horizontal force satisfies the limit criterion.

    Abstract: A method for altering the width of a strip-shaped rolled material (5), before, during or after hot rolling the rolled material in a hot rolling mill. The problem is to specify a method for altering width so that the length of a rolled out transition piece lying outside width tolerances can be reduced. Scrap losses are to be reduced. The crown of at least one working roll and/or at least one backing roll of a stand (7) is set as a function of a width error e=B−B between a setpoint width Bsetp and the width B of the rolled material (5), wherein the crown is increased when e>0 and the crown is reduced when e

    Abstract: Methods and apparatus to monitor conditioning machines are disclosed herein. An example system includes a plurality of work rolls to process a continuous strip material positioned between an entry and an exit of an apparatus. A sensor determines a measured distance between an upper surface of the strip material and a reference location, where the sensor is downstream from the exit of the apparatus. A controller determines a difference value between the measured distance and a predetermined distance to detect material curvature in the strip material.

    Abstract: Methods and apparatus to monitor conditioning machines are disclosed herein. An example system includes a plurality of work rolls to process a strip material. A first sensor detects a first distance between an upper surface of the strip material and a first reference location and a second sensor detects a second distance between an upper surface of the strip material and a second reference location. A controller determines a difference value between the first distance and the second distance to detect material curvature of the strip material.

    Abstract: The invention relates to a method, a computer program and a rolling mill train for cold rolling a metal strip (200). In order to achieve a shortening of undesired off-gauge lengths, the method according to the invention provides that the head (210) of the metal strip (200) already undergoes a thickness reduction at the first active rolling stand (n) in the rolling mill train, and then is transported on to the next rolling stand, in order to undergo a further thickness reduction there. The method according to the invention also provides for further reducing the initial pass thickness at the n-th rolling stand in accordance with the tensile stress that has built up in the meantime between the n+1-th and the n-th rolling stand.
