摘要： An assembly, system and method for compensating a crane position offset error based on wheel float by viewing, with an optical sensor located on a trolley on the crane, a target or target shape adjacent a storage rack containing a vertically stored mill roll and determining a positional compensation signal based on a separation or offset of a center of a field of view of the sensor from a center of the target shape. The assembly, system or method compensates for the crane position offset error by moving the crane, as instructed by the positional compensation signal, a distance equal to the separation or offset of the center of the field of view of the sensor from the center of the target.

摘要： The invention relates to a roll stand (2) for rolling, in particular cold-rolling, metal products, comprising at least one actuator (16) which can be actuated for actively damping vibrations in the roll stand (2), and at least one supporting roll (10) which is non-adjustable or can be adjusted exclusively via a readjusting device for pass line adjustment (13) of the roll stand (2) for supporting a working roll (5) and/or intermediate roll of the roll stand (2), wherein the supporting roll (10) is guided at the ends via a respective bearing unit (11) on a rack (8) of the roll stand (2). In order to enable an optimal active damping of vibrations in a roll stand (2) of this type with low engineering effort, the invention proposes that the supporting roll (10) is supported on the actuator (16) via at least one bearing unit (11) and that the actuator (16) is supported on a section (17) of the rack (8) either directly or indirectly via at least one component (14) of the readjustment device (13).

摘要： The present invention includes (1) inputting, into a model expression that defines relation between various operating values of a facility operating on a material to be rolled and energy consumption of the facility, various actual operating values as the various operating values, to calculate an actual calculation value of the energy consumption; (2) dividing the actual value of the energy consumption by the actual calculation value to calculate a reference learning value of the energy consumption; (3) inputting the set operating value defined by the setting calculation unit only in one operating value, among various operating values of the model expression, while inputting the actual operating values collected by the actual value unit in other operating values to calculate a pseudo-actual calculation value of the energy consumption; (4) dividing the actual calculation value by the pseudo-actual calculation value to calculate a correction learning value; and (5) inputting the various set operating values as the various operating values of the model expression to calculate a prediction value of the energy consumption for the material to be rolled, which is scheduled to be conveyed to the rolling line next time or later, and multiplies the prediction value by the reference learning value and the correction learning value to calculate a corrected prediction value of the energy consumption.

摘要： A method to generate a plurality of groups each including at least one of a plurality of elements. The method includes selecting at least one candidate element from the plurality of elements as a candidate to be included in a group, determining whether or not to generate the group including the at least one candidate element selected in the selecting step, based on an element evaluation value associated with each of the at least one candidate element selected in the selecting step, provided that a determination is made to generate the group in the determining step, generating the group including the at least one candidate element selected in the selecting step, and weighting the element evaluation value of each of the at least one element according to how many times the each element is included in already-generated groups to reflect the weighted element evaluation value in next group generation.

摘要： A control computer for a rolling train is supplied with prescribed stand parameters of a rolling stand of the rolling train. The control computer sets variables describing a rolling pass of the rolling stand that together with initial data of a flat piece to be rolled and the stand data describe the resultant roll nip and the asymmetry thereof. The initial data may be width, average thickness and average strength of the workpiece to be rolled. Based on the initial data, the stand data and the set variables an expected delivery taper and/or an expected strip sabre for the workpiece is determined. At least one of the set variables is manipulated to bring the determined delivery taper close to a desired delivery taper and/or the strip sabre close to a desired strip sabre. The manipulated variables are used to control rolling the workpiece piece.
