Abstract: During rolling of front sections of rolling material in a rear group of roll stands of a rolling mill, rear sections of the rolling material are rolled in the front group of roll stands. A run-out speed with which the rolling material is exiting the front group of roll stands is detected. A run-in speed with which the rolling material is entering the rear group of roll stands is detected. A rolling speed with which the rear group of roll stands is driven is controlled by a controller such that a relation of the run-in speed to the run-out speed equals a predetermined value. The predetermined value is kept constant until a time point at which a tail end of the rolling material reaches a predetermined location upstream of the front group of roll stands, and is changed according to a predetermined function after the time point.

Abstract: Before a first strip point is fed into a production line, an actual energy content at a location in front of the production line and a setpoint energy content at a location behind the production line are received for a first strip point, second strip point, and third strip point. The third strip point, followed by the first strip point, followed by the second strip point, are fed into the production line. A command variable for the first strip point and second strip point(s) is determined prior to feeding in the first strip point. Each command variable is determined based on (a) the actual value and the setpoint value of the strip point currently entering the production line, and (b) the actual value and the setpoint value of at least one strip point having already entered.

Abstract: A plurality of flat metal items to be rolled (3) are fed to a plurality of rolling stands (1, 2) of a rolling installation, one after the other over a feed path (4). The items (3) are rolled by the rolling stands (1, 2) past which they are fed. In the rolling stands (1, 2), the flat item to be rolled (3) is first rough-rolled in at least one roughing pass with a wedge-type roll gap adjustment (ds) and then finish-rolled in finishing passes. After the finish-rolling of the flat item, a thickness taper (dd) that is present in the respective finish-rolled flat item is recorded by measuring instruments. The thickness taper (dd) is compared with a target taper (dZ). On the basis of a deviation of the thickness taper (dd) from the target taper (dZ) and the wedge-type roll gap adjustment (ds), a new wedge-type roll gap adjustment (ds) is determined for the at least one roughing pass. The wedge-type roll gap adjustment (ds) for the at least one roughing pass for the next flat item to be rolled (3) is set to correspond to the newly determined value of the wedge-type roll gap adjustment (ds), so that the next flat item to be rolled (3) is rough-rolled in the at least one roughing pass with the newly determined value of the wedge-type roll gap adjustment (ds).

Abstract: A billet (2) is rolled to a rod (3) in a rolling mill. The rod (3) exits the rolling mill with a finishing temperature (TE1). A rear laser measurement device (8) arranged downstream of the rolling mill detects the head end and the speed (v) of the rod (3). The detected speed (v) of the rod (3) is integrated to its length and an instantaneous length (L) of the rod (3) is determined. Dependent on the determined instantaneous length (L) of the rod (3), cutting commands (S) to a rear shears (5) arranged downstream of the rolling mill are provided for cutting the rod (3) in sections (6) of predetermined length (L0). The sections (6) of the rod (3) are cooled down in a cooling bed (7).

Abstract: Drive loads for a plurality of drives of a mill train for rolling rolling stock with a plurality of rolling stands each being assigned at least one drive, are adjusted essentially to a first set point value on the basis of operation of the mill train in accordance with a first pass sequence. Redistribution of drive loads is improved, by adjusting the drive loads during the rolling to a second set point value different from the first set point value based on operating the mill train in accordance with a second pass sequence different from the first pass sequence, wherein at least during the adjustment of the second set point values a feed rate of the rolling stock into the mill train is adjusted as a function of a discharge rate of the rolling stock which is arranged upstream of the mill train in the direction of mass flow.

Abstract: A strip is fed a rolling stand of a multi-stand rolling mill with a known inlet thickness and exits with a strip thickness. Measurement parameters are determined that are characteristic of the inlet-side and outlet-side strip velocities. With the measurement parameters, the inlet-side and outlet-side strip velocities are determined with respect to the rolling stand. With the inlet thickness, the inlet-side and outlet-side strip velocities, the strip thickness is determined with respect to the rolling stand. Taking into account the determined strip thickness, further measures are taken. The measurement parameter for the inlet-side velocity is the roller peripheral velocity directly prior to the rolling stand. Alternatively or in addition, the measurement parameter for the outlet-side velocity is the roller peripheral velocity. The peripheral precession of the strip is modeled. The respective strip velocity is determined using the respective roller peripheral velocity and the peripheral strip precession in the respective rolling stand.

Abstract: Disclosed is a rolling mill comprising a roll stand with working rolls, a roll train located at the feeding end of the roll stand, and a control device. The working rolls form a roll gap. The control device triggers the roll stand such that the working rolls rotate at a certain peripheral speed while triggering the roll train located at the feeding end of the roll stand in such a way that the leading edge of the strip-shaped rolling stock reaches the roll gap at a feeding speed that is greater than the peripheral speed. The control device adjusts the peripheral speed and the feeding speed to each other in such a way that a potential angled position of the leading edge relative to the roll gap is at least reduced as a result of said adjustment.

Abstract: A seamless steel tube is manufactured from a high alloy steel containing at least 5% of Cr while effectively preventing mandrel bar withdrawal troubles after elongation rolling of a material being rolled. A seamless steel tube of a high alloy steel containing at least 5% of Cr is manufactured by subjecting a material being rolled 3 to elongation rolling using a retained mandrel mill 1 in which the speed of a mandrel bar 2 in the axial direction is maintained constant while the speed of movement Vb of the mandrel bar 2, the speed Vi of the material being rolled 3 on the inlet side of the retained mandrel mill 1, and the speed Ve of the material being rolled 3 on the exit side of the retained mandrel mill 1 satisfy the relationship: 0.15 ≦Vb/{Vi+Ve)/2}≦0.70 by controlling the speed of movement Vb of the mandrel bar 2.
