A device for cooling rolled stock, preferably for cooling during cold rolling, including a nozzle for applying a cooling medium to the rolled stock, wherein a cooling chamber that is in fluid communication with the nozzle and extends substantially parallel to the strip running plane is provided for applying the cooling medium to the rolled stock.

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.

An installation for rolling a metal strip includes a rolling mill through which the strip is rolled as it passes continuously, rolling agents brought into contact with rolls of the rolling mill and with the strip, a strip drawing unit positioned at the outlet of the rolling mill, and a decontamination module with at least one degreaser positioned between the outlet of the rolling mill and the drawing unit so as to remove residual rolling agents from the strip at the outlet from the rolling mill. A strip accumulator is positioned at the outlet of at least part of the drawing unit, particularly so as to keep the speed of travel of the strip at the outlet of the accumulator below a maximum threshold. A paper-strip insertion module is positioned downstream of the outlet from the strip accumulator.

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).
