Abstract: A cooling group for a laminar cooling device, including at least one cooling unit arranged above and below a strip to be cooled in order to supply the strip with a cooling liquid, including a central inlet via which cooling liquid is supplied, a distributing tube supplied with cooling liquid by the central inlet, and a number of supplying units supplied with cooling liquid from the distributing tube. Each supplying unit has a number of cooling nozzles via which cooling liquid is discharged onto the strip. In order to minimize the influence of the number of supplying units which are switched on or switched off, and thus have as little expenditure as possible, a volumetric flow rate regulating valve is arranged in or in front of the central inlet. The regulating valve is used to conduct a defined volume of cooling liquid through the central inlet per unit of time.

Abstract: A device and a method for cooling metal strips or sheets conveyed on a conveyor line, in particular hot-rolled strips in the outlet of a rolling train. For these purposes, the device includes at least one cooling beam extending across the width of the conveyor line, and the cooling beam features a connection point to which a supply tube for cooling liquid can be connected, and a number of discharge openings arranged along a longitudinal axis of the cooling beam, such that cooling liquid can be discharged through the discharge openings in the direction of the metal strip or sheet that is to be cooled. Associated with each of the individual discharge openings is a respectively adjusted flow area, such that the flow areas of the respective discharge openings decrease in a direction leading away from the connecting point along the longitudinal axis of the cooling beam.
