Cooling device for a flat rolled product, - wherein the flat rolled product passes through the cooling device in a transportation direction (x) at the level of a passline, - wherein the cooling bed has a number of spray bars (5, 6) extending transversely with respect to the transportation direction (x), - wherein the respective spray bar (5, 6), when viewed transversely to the transportation direction (x), has two outer sections (7, 8) and a central section arranged between the two outer sections (7, 8), - wherein a liquid cooling medium can be injected into the sections (7, 8, 9) via a respective dedicated, individually controllable valve device (10, 11, 12), characterised in that - the flat rolled product can be impinged upon with a central flow rate profile of the liquid cooling medium by means of outlet orifices arranged in the central section, which central flow rate profile, when viewed transversely to the transportation direction (x), is at a maximum in the centre and decreases towards the edge, such that the central flow rate profile defines a central triangle in which one side runs transversely to the transportation direction (x) and the two other sides are of equal length, - the flat rolled product can be impinged upon with a respective outer flow rate profile (V2, V3) of the liquid cooling medium by means of outlet orifices (16, 17) arranged in the outer sections (7, 8), which respective outer flow rate profile (V2, V3), when viewed transversely to the transportation direction (x), is at a maximum at the respective edge and decreases towards the centre, such that the outer flow rate profiles (V2, V3) in each case define an outer triangle in which one side runs parallel and one side runs transversely to the transportation direction (x), and - the central triangle and the two outer triangles combine to form a rectangle. - wherein the flat rolled product passes through the cooling device in a transportation direction (x) at the level of a passline, - wherein the cooling bed has a number of spray bars (5, 6) extending transversely with respect to the transportation direction (x), - wherein the respective spray bar (5, 6), when viewed transversely to the transportation direction (x), has two outer sections (7, 8) and a central section arranged between the two outer sections (7, 8), - wherein a liquid cooling medium can be injected into the sections (7, 8, 9) via a respective dedicated, individually controllable valve device (10, 11, 12), - the flat rolled product can be impinged upon with a central flow rate profile of the liquid cooling medium by means of outlet orifices arranged in the central section, which central flow rate profile, when viewed transversely to the transportation direction (x), is at a maximum in the centre and decreases towards the edge, such that the central flow rate profile defines a central triangle in which one side runs transversely to the transportation direction (x) and the two other sides are of equal length, - the flat rolled product can be impinged upon with a respective outer flow rate profile (V2, V3) of the liquid cooling medium by means of outlet orifices (16, 17) arranged in the outer sections (7, 8), which respective outer flow rate profile (V2, V3), when viewed transversely to the transportation direction (x), is at a maximum at the respective edge and decreases towards the centre, such that the outer flow rate profiles (V2, V3) in each case define an outer triangle in which one side runs parallel and one side runs transversely to the transportation direction (x), and - the central triangle and the two outer triangles combine to form a rectangle.
