Abstract: A cooling device for cooling a material to be cooled, comprising an inlet for a cooling medium conducted into a first, upper chamber of the cooling device. First conduits are provided which conduct the cooling medium from the upper chamber into a second, lower chamber of the cooling device. The upper chamber is separated from the lower chamber by a wall. Second conduits are provided which conduct the cooling medium from the lower chamber to at least one outlet opening for cooling medium, via which the cooling medium is discharged onto the material to be cooled.

Abstract: A cooling device with variable cooling rate for treating metal materials, in particular for cooling steel sheets in plate mills, hot strip mills or thermal treatment lines, by means of a spray nozzle cooling system. The cooling device consists of at least two cooling bars one of each two cooling bars being situated on the lower side and the other on the upper side transversely to the sheet travel direction of the sheet and centrally between two roller table rollers and includes a spray nozzle cooling system with which a plurality of full jet nozzles and a plurality of full cone nozzles are associated, the full jet nozzles being arranged symmetrically to the full cone nozzles. A method for operating the cooling device according to the disclosure.

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.

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: 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.

Abstract: A device for detecting the presence of rolling or cast stock, more particularly a metal strip or plate, in a casting, rolling or other strip processing facility, wherein the device includes a detection device for detecting a fluid jet which indicates the presence of the rolling or cast stock. The detection device in turn has an air-filled cavity, which has a tubular opening, and a pressure sensor for detecting an air pressure change in the cavity when the fluid jet hits the tubular opening. A corresponding method for determining the position of rolling or cast stock, more particularly a metal strip or plate, which moves through a casting, rolling or other strip processing facility.
