Abstract (en)
[origin: WO2020020868A1] The invention relates to a cooling section (2) arranged within a rolling train or upstream or downstream of the rolling train. A hot-rolled product (1) made of metal is cooled by means of the cooling section (2). Application devices (6) of the cooling section (2) are supplied with a respective actual current (F) of a water-based liquid coolant (7) via a respective supply line (8) and a respective pump (10). The respective actual current (F) of the coolant (7) is applied to the hot-rolled product (1) by means of the respective application device (6). The hot-rolled product (1) is transported within the cooling section (2) in a horizontal transport direction (x) during the application of the coolant (7). A controller (11) of the cooling section (2) dynamically ascertains a respective target actuation state (S*) for each pump (10) on the basis of a respective target current (F*) of the coolant (7) to be applied onto the hot-rolled product (1) by means of the respective application device (6) and controls the respective pump (10) in a corresponding manner such that the respective actual current (F) delivered by each pump (10) approximates the respective target current (F*) as much as possible at any time.
