Abstract: The invention relates to a cooling device 100 for cooling a metallic product and a method for its operation. The cooling device 100 has at least one cooling bar 110 with a plurality N of spraying regions I, II, III which are adjacent in pairs and which each have at least one spray nozzle 130 for spraying a coolant onto the metallic product. Valves are provided for individually adjusting the pressure or the volume flow of the coolant 300 in each of the spraying regions. The valves 120 and a pump for the coolant are controlled individually with the aid of a control device 150. In order to improve the application of coolant to the metallic product, the invention provides that at least one partition wall is provided for the at least one cooling bar of the cooling device according to the invention to divide the interior of the cooling bar into at least two chambers, each of the spraying regions being assigned to a different one of the chambers. The partition wall is shaped at least approximately in accordance with the course of the temperature distribution in a predetermined width section of the metallic product before it enters the cooling device, and the partition wall is arranged in the cooling bar over this width section.

Abstract: A cooling apparatus for cooling a metallic material has at least one cooling beam with a plurality of coolant application elements for applying the metallic material with a coolant. Each coolant application element has an outlet opening with a cross-sectional area for discharging the coolant. In order to be able to adapt such known cooling apparatuses even more precisely to different temperature distributions across the width of the metallic material to be cooled the density of the cross-sectional areas of the outlet openings of the coolant application elements in the width direction y of the cooling beam be distributed or dimensioned according to the amount of the slope of the distribution of the temperature T(y) of the metallic material across its width before the inlet under the cooling beam.
