Abstract: There are provided a work-side position measurement device and a drive-side position measurement device for directly measuring positions of roll chocks in a rolling direction, and positions of upper and lower working rolls and upper and lower backup rolls in the rolling direction are adjusted to zero point or predetermined positions. Alternatively, a change caused in the strip wedge due to a minute crossing of the axes of working rolls and backup rolls is calculated, and the quantities of leveling of a work-side rolling reduction cylinder device and a drive-side rolling reduction cylinder device are adjusted to make the strip edge equal to or smaller than a predetermined value. Accordingly, the bilateral asymmetry (strip wedge) of the thickness distribution of a rolled material is easily adjusted even in the event that the positions of the roll chocks in the rolling direction are changed due to wear on various components.

Abstract: The present disclosure provides a strip flatness prediction method considering lateral spread during rolling. The method includes: step 1: acquiring strip parameters, roll parameters and rolling process parameters; step 2: introducing a change factor of a lateral thickness difference before and after rolling and a lateral spread factor by considering lateral metal flow, and constructing a strip flatness prediction model based on the coupling of flatness, crown and lateral spread; step 3: constructing a three-dimensional (3D) finite element model (FEM) of a rolling mill and a strip, simulating strip rolling by the 3D FEM, extracting lateral displacement and thickness data of the strip during a stable rolling stage, calculating parameters of the strip flatness prediction model based on the coupling of flatness, crown and lateral spread; and step 4: predicting the flatness of the strip by the strip flatness prediction model based on the coupling of flatness, crown and lateral spread.

Abstract: A control device of the rolling mill line controls actuators of a downstream and an upstream roll stand. The control device determines control variables for the actuators of the upstream roll stand while taking into consideration a flatness change to be carried out and additionally taking into consideration a contour change to be carried out and controls the actuators of the upstream roll stand accordingly. The control device determines control variables for the actuators of the downstream roll stand while taking into consideration the contour change to be performed but without taking into consideration the flatness change to be performed and controls the actuators of the downstream roll stand accordingly. The control device outputs the control variables to the actuators of the downstream roll stand with a delay of a transport time, relative to the corresponding control variables for the actuators of the upstream roll stand.

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.
