Abstract
A method for detecting a faulty cooling unit in a set of cooling units configured to provide a coolant to work rolls arranged to process a work item therebetween, the method including: varying the flow rates of the coolant ejected from a sub-set of the cooling units; in response to varying the flow rates, determining a flatness variation value of the work item for at least each of the cooling units in the sub-set of cooling units, the flatness variation value being indicative of the work item flatness variation downstream of the work rolls; and detecting a faulty cooling unit based on comparing the flatness variation values to a reference flatness variation value.
