Abstract

A method and apparatus for cooling hot-rolled rolling stock, wherein, for cooling preferably both sides of hot-rolled wide strip, a heat exchange is carried out between the rolling stock and the cooling medium by a pressurized water flow through a sequence of a pressure chamber and a convection chamber, and wherein the rolling stock is cooled by a targeted control of the intensity of the forced convection. The method utilizes a combination of a cooling unit between stands and an additional roll cooling unit in the area of the roll gap at the exit side thereof using a directed pressurized water flow along a circumferential portion of the roll body of each work roll, wherein the cooling unit between stands and the roll cooling unit each operate with contactless sealing means for the surface of the rolling stock and the surface of the roll body.
