| 摘要 |
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). |

1. A cooling section for a flat rolled material (1),
where the cooling section has a structural frame (2) in which is arranged a plurality of transport rollers (3) which are one behind another looking in the direction of transport (x) of the flat rolled material (1), where, looking in the direction of transport (x), immediately neighboring transport rollers (3) are in each case separated by a gap (a), where each of the transport rollers (3) is mounted in the structural frame (2) so that it can rotate about a roller axis (4), where the roller axes (4) are aligned orthogonally to the direction of transport (x) and horizontally, so that the transport rollers (4) form a pass-line (5) for the flat rolled material (1), where at least one lower spray bar (6) is arranged underneath the pass-line (5), where the at least one spray bar (6) has a base block (7) arranged underneath the transport rollers (3), into which is fed a liquid coolant (8), where a number of feeder sections (9) project upwards from the base block (7) into spaces between the transport rollers (3), where the feeder sections (9) have an upper closing element (10), on which are arranged spray nozzles (11), by means of which the coolant (8) fed into the base block (7) is sprayed from below onto the flat rolled material (1), where each of the feeder sections (9) has a width (1) looking in the direction of transport (x) of the flat rolled material (1), where, at least in the neighborhood of the relevant upper closing elements (10), the widths (1) reduce in the direction towards the upper closing element (10) concerned. |
