Cooling system for cooling metal rolling stock

A method for lubricating the cylinders of a roll stand, for roll nip lubrication in a roll stand for a roll band. A mixture of water and oil is produced by a mixing and spraying device, which is supplied with water by a first supply line () and is supplied with oil by a second supply line (). The mixture is sprayed to the strip and/or into the roll nip and/or to at least one of the cylinders of the roll stand. The water flowing to the mixing and spraying device () is heated by a heating device () provided in the first supply line () for a predetermined period of time set by controlling a control unit ().
