METHOD FOR PROCESSING MATERIAL TO BE ROLLED ON A ROLLING LINE, AND ROLLING LINE

摘要

A method for machining rolled stock (6) in a rolling train (2), the train including at least one rolling block (20, 20a, 20b) having at least two rolling stands (4) with each stand including at least one roll (13). Each rolling stand (4) has a separate drive (8) with a speed controller (14) for its roll (13). A time (tZW) that is dependent on the point in time (tB) that an actual loading moment is applied to the drive (8) of the first rolling stand (4) of the rolling block (20, 20a, 20b), for controlling the speed of the drive (8). An additional value (ZW), dependent on an expected actual loading moment, is fed to the speed controller (14) of each drive (8). Also, a rolling train (2) for machining rolled stock (6), is disclosed having the features above and having an open-loop/closed-loop control unit (24), in which software for the method is implemented.

1. A method for processing materials to be rolled in an advancing direction on a rolling line wherein
the rolling line includes at least one rolling section, each rolling section having at least two roll stands arranged in the advancing direction, each roll stand having at least one roll configured and operable for enabling movement of the materials in the advancing direction; a separate respective drive with a rotational speed regulator for the at least one roll of each roll stand for moving the materials in the advancing direction; the method comprising: at a point in time, which depends on a time point at which a real load moment caused by the materials moving in the advancing direction is imposed on the drive of the first roll stand in the rolling section for the purpose of regulating the rotational speed of the drives in each case, feeding a supplementary value, which is a function of an expected real load moment, to the rotational speed regulator of each drive, wherein the feeding of the supplementary value is simultaneous with the rotational speed regulator of the drive of the first roll stand and with the rotational speed regulators of the drives of the subsequent roll stands in a same rolling section such that the supplementary value regulates the rotational speed regulators to regulate the rotation speeds of the drives.
