Patent ID: 7159433

Claim:
Method for cooling and/or lubricating work rolls ( 2 , 3 ) of a rolling stand, and rolling stock ( 1 ) passed between the rolls during the rolling operation, with the use of water in the form of spray jets ( 4 , 5 ) as the cooling medium and the use of oil, an oil-air mixture, an oil-water mixture, or an oil-water-air mixture, or grease or a grease-medium mixture as the lubricant, in which the water and lubricant are supplied separately to the rolls and the rolling stock ( 1 ) and are applied to the roll surface and the rolling stock surface at different application sites on the run-in side of the rolling stand, and the lubricant is applied to largely water-free regions of the surface of the rolls to produce a film with the greatest possible adhesive strength, such that application regions ( 6 , 7 ; 6 ′, 7 ′) for the application of the two media, water and lubricant, are separated from each other by wipers ( 8 , 9 ), wherein, depending on boundary conditions and requirements, either only a lubricant is applied, or only the rolling stock cooling system is activated.
