Abstract
To cool a metal strip (), liquid coolant () is supplied to the strip by a supply device () from a feed line (). A valve () in the feed line () sets the valve () to a respective opening position (s) for adjusting the coolant flow (F) to the metal strip () per unit of time. An upstream condition detection device () upstream of the valve device () in the feed line () detects an upstream condition (ZV) of the coolant (). A control unit () determines a set point (s*) for an opening position (s) of the valve device () 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 () and a valve characteristic (C) of the valve device (). 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 (), relative to a reference condition (ZR) of the coolant () upstream of the valve device () in the feed line (). The control unit () sets the opening position (s) of the valve device () according to the set point (s*) that has been determined.
