Cooling system for a metallurgical plant, by which metal products can be acted on directly by a coolant, comprising - at least one delivery means for direct action on a metal product by the coolant, - at least one setting means for setting a volume flow, which is fed to the delivery means, of the coolant, - at least one pressure increasing means for supply of the setting means with the coolant, - at least one pressure detecting means for detecting a coolant pressure (p istnx) between the delivery means and the setting means, - at least one pressure detecting means for detecting a coolant pressure (p ist) between the pressure increasing means and the setting means and - at least one volume flow detecting means for detecting a coolant volume flow actual value (V istnx), characterised by - at least one evaluating means which is arranged to determine a coolant pressure target value (p soll) with consideration of the detected coolant pressure (p istnx) between the delivery means and the setting means, the detected operational state of the setting means, the detected coolant pressure (p ist) between the pressure increasing means and the setting means and/or a volume flow pressure characteristic curve of the delivery means, and - at least one regulating device, which is arranged between the evaluating means and the pressure increasing means, for determining a regulating difference between the coolant pressure target value (p soll) and the coolant pressure (p ist) and for regulation of the coolant pressure (p ist) between the pressure increasing means and the setting means to the coolant pressure target value (p soll) by controlling the pressure increasing means as setting element according to the regulating difference. - at least one delivery means for direct action on a metal product by the coolant, - at least one setting means for setting a volume flow, which is fed to the delivery means, of the coolant, - at least one pressure increasing means for supply of the setting means with the coolant, - at least one pressure detecting means for detecting a coolant pressure (p istnx) between the delivery means and the setting means, - at least one pressure detecting means for detecting a coolant pressure (p ist) between the pressure increasing means and the setting means and - at least one volume flow detecting means for detecting a coolant volume flow actual value (V istnx), characterised by - at least one evaluating means which is arranged to determine a coolant pressure target value (p soll) with consideration of the detected coolant pressure (p istnx) between the delivery means and the setting means, the detected operational state of the setting means, the detected coolant pressure (p ist) between the pressure increasing means and the setting means and/or a volume flow pressure characteristic curve of the delivery means, and - at least one regulating device, which is arranged between the evaluating means and the pressure increasing means, for determining a regulating difference between the coolant pressure target value (p soll) and the coolant pressure (p ist) and for regulation of the coolant pressure (p ist) between the pressure increasing means and the setting means to the coolant pressure target value (p soll) by controlling the pressure increasing means as setting element according to the regulating difference.
