Abstract: A cooling section for a flat rolled material (1) has a frame structure (2), in which a plurality of transport rollers (3) for the flat rolled material (1) are arranged one after another transversely to a transport direction (x) and spaced apart (a). Each transport roller (3) mounted in the frame structure (2) rotates 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) arranged beneath the pass line (5) has a base block (7) beneath the transport rollers (3) for a liquid coolant (8). Guide sections (9) project upwards from the base block (7) into spaces between the transport rollers (3). Each guide section (9) has an upper terminating element (10) on which spray nozzles (11) are arranged, which feed the coolant (8), which had been fed into the base block (7), to be sprayed onto the flat rolled material (1) from below. The guide sections (9) have a respective length (1) in the transport direction (x) of the flat rolled material (1). That length (1) decreases at least in the vicinity of the respective upper terminating elements (10), in the direction of the respective upper terminating element (10).

Abstract: A flat rolled article (2) passes through a cooling device (1) in a transportation direction (x) at the level of a passline (3). Spray bars (5, 6) extend transversely with respect to the transportation direction (x). The spray bars (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 respective dedicated, individually controllable valve devices (10, 11, 12). Flow rate profiles, pertaining to each region may be set, wherein each region (7, 8, 9) is triangular in shape. The central triangle and the two outer triangles combine to form a rectangle.

Abstract: Device for cooling flat rolled material with a liquid coolant has at least one cooling bar, which is arranged above the conveying path and to which the liquid coolant is fed. A plurality of outlet tubes have, in a flow direction of the liquid coolant, an initial portion, which proceeds from the inlet opening and extends upward, a middle portion, which adjoins the initial portion, and an end portion, which adjoins the middle portion and extends downward and to the output opening. The middle portion contains a vertex at which the coolant flowing through the outlet tube in question reaches a highest point. The outlet openings are located above the cooling bar. A height distance (h1) of the inlet opening from the vertex is at least twice as large, in particular at least three times as large, as a height distance (h2) of the outlet opening from the vertex.

Abstract: 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 beams (3i). The liquid coolant (4) is fed from a reservoir (7) for the liquid coolant (4) to the spray beams (3i) by means of a pump (5) and a supply system (6). Valves (9i) are arranged upstream of the spray beams (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 beam (3i). Also, 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 beams (3i).

Abstract: To cool a metal strip (1), liquid coolant (5) is supplied to the strip by a supply device (9) from a feed line (10). A valve (13) in the feed line (10) sets the valve (13) to a respective opening position (s) for adjusting the coolant flow (F) to the metal strip (1) per unit of time. An upstream condition detection device (14) upstream of the valve device (13) in the feed line (10) detects an upstream condition (ZV) of the coolant (5). 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) based on 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.
