    Abstract: A cooling device for cooling a metallic product has at least one cooling bar with a plurality of spraying regions which are adjacent in pairs defined by one or more moveable partition walls. Each spraying region has at least one spray nozzle for spraying a coolant onto the metallic product. A control device controls a pump and valves for individually adjusting pressure and/or volume flow of the coolant in each of the spraying regions. The one or more partition walls 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 a temperature distribution along a width section of the metallic product before it enters the cooling device. The partition wall is arranged in the cooling bar over this width section.

    Abstract: The invention relates to a method for cooling a metallic item (1) by discharging a cooling medium from a cooling bar (2) onto the item (1), wherein the cooling medium is discharged through a slot (3) in the cooling bar (2). According to the invention, in order to achieve improved cooling, during the cooling process the width (B) of the slot (3) in the conveying direction (F) of the item (1) or of the cooling bar (2) is altered in order to bring the cooling power of the cooling medium to a desired or predefined level by open-loop or closed-loop control. In addition, the invention relates to a cooling bar.

    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. 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. A method for cooling a metallic material so includes determining a temperature distribution of the metallic material to be cooled and producing or selecting a cooling beam to match the temperature distribution of the metallic material.
