Abstract
A method for cooling a rolled product in a cooling section which is located upstream of a finishing train of a hot rolling mill. The cooling section includes a cooling device which can deliver a coolant flow of a coolant onto a rolled product surface of the rolled product. In the method, a coolant flow is delivered, by means of each cooling device and in each cooling section pass, onto the rolled product surface, which flow is set to a set value that is assigned to the relevant cooling device for the cooling section pass. The set values for a cooling section pass are determined in a simulation of the cooling section pass so that surface temperatures, determined in the simulation, of the rolled product surface upon leaving active regions of the cooling device do not exceed a minimum value for a surface temperature of the rolled product surface.
