    摘要： In order to cool a metal strip (1), a liquid coolant (5) is supplied to said strip by means of a supply device (9). The coolant (5) is fed to the supply device (9) via a feed line (10). A valve device (13) is arranged in the feed line (10). By setting the valve device (13) to a respective opening position (s), the coolant flow (F) which is supplied to the metal strip (1) by the supply device (9) per unit of time can be adjusted continuously or in several stages. An upstream condition detection device (14) is located upstream of the valve device (13) in the feed line (10) and is used to detect an upstream condition (ZV) of the coolant (5) upstream of the valve device (13) in the feed line (10). A control unit (6) determines a set point (s*) for an opening position (s) of the valve device (13) corresponding to the set point (F*) for the coolant flow (F), on the basis of a set point (F*) for the coolant flow (F*), the upstream condition (ZV) of the coolant (5) and a valve characteristic (C) of the valve device (13). The valve characteristic (C) follows a characteristic curve (K) of the coolant flow (F) as a function of the opening position (s) of the valve device (13), relative to a reference condition (ZR) of the coolant (5) upstream of the valve device (13) in the feed line (10). The control unit (6) sets the opening position (s) of the valve device (13) according to the set point (s*) that has been determined.

    摘要： A cooling section for flat rolling stock (1) has a working region (2), through which the flat rolling stock (1) is guided. The working region (2) can be supplied with a liquid coolant (4) by means of a number of spray bars (3i). The liquid coolant (4) is fed from a reservoir (7) for the liquid coolant (4) to the spray bars (3i) by means of a pump (5) and a supply system (6). Valves (9i) are arranged upstream of the spray bars (3i) in the supply system (6). Opening positions (si) of the valves (9i) are set by a control unit (10) of the cooling section according to a respective sub-flow (fi) that is to be applied to the flat rolling stock (1) by means of each spray bar (3i). The delivery rate (M) of the pump (5) and/or a line pressure (p) generated by the pump (5) in the supply system (6) are set by the control unit (10) according to the total flow (F) that is to be applied to the flat rolling stock (1) by means of all the spray bars (3i).

    摘要： A flat rolled article (2) passes through a cooling device (1) in a transportation direction (x) at the level of a passline (3). Spray beams (5, 6) extend transversely with respect to the transportation direction (x). The spray beams (5, 6) have, as viewed perpendicular to the transportation direction (x), in each case two outer regions (7, 8) and a central region (9) in between. A liquid cooling medium (13) can be fed into the regions (7, 8, 9) via a respective dedicated, individually controllable valve device (10, 11, 12). A central flow rate profile (V1), pertaining to the central region (9), of the liquid cooling medium (13) has a maximum in the centre and decreases toward the edge as viewed perpendicular to the transportation direction (x), such that the central flow rate profile (V1) defines a central triangle of which one side runs perpendicular to the transportation direction (x) and the two other sides are of equal length. Outer flow rate profiles (V2, V3), pertaining to the outer regions (7, 8), of the liquid cooling medium (13) have a maximum at the edges and decrease toward the centre, such that the outer flow rate profiles (V2, V3) each define an outer triangle of which in each case one side runs parallel and perpendicular to the transportation direction (x). The central triangle and the two outer triangles combine to form a rectangle.

    摘要： A cooling section for a flat rolled material (1) has a frame structure (2), in which a plurality of transport rollers (3) are arranged one after another as seen in a transport direction (x) for the flat rolled material (1). Transport rollers (3) that are immediately adjacent as seen in the transport direction (x) are at a respective distance (a) from each other. The transport rollers (3) are mounted in the frame structure (2) such that they can rotate about a respective roller axis (4). The roller axes (4) run orthogonally to the transport direction (x) and horizontally, so that the transport rollers (4) form a pass line (5) for the flat rolled material (1). At least one lower spray bar (6) is arranged beneath the pass line (5). The at least one lower spray bar (6) has a base block (7), which is arranged beneath the transport rollers (3) and into which a liquid coolant (8) is fed. A number of guide sections (9) project upwards from the base block (7) into intermediate spaces between the transport rollers (3). The guide sections (9) have an upper terminating element (10), on which spray nozzles (11) are arranged, by means of which the coolant (8) fed into the base block (7) is sprayed onto the flat rolled material (1) from below. The guide sections (9) have a respective length (l) as seen in the transport direction (x) of the flat rolled material (1). The lengths (l) decrease at least in the vicinity of the respective upper terminating elements (10), in the direction of the respective upper terminating element (10).
