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: 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.
