Abstract

PURPOSE:To obtain an internal water-cooling type cooling roll having a large overall heat transfer coefficient, a high cooling rate, and a high cooling capacity by providing a doughnutlike cooling water path within a specific distance from the peripheral surface in the operation of the water-cooling roll for cooling a metal strip. CONSTITUTION:Within a distance of 5X10<-3>.lambdas(m) (lambdas is the thermal conductivity of a metal making up the roll at the peripheral surface side from the cooling water path, in Kcal/m.h. deg.C) from the peripheral surface of the roll 1 on a section of a roll 1 for cooling a strip vertical to the longitudinal direction of the roll, a cooling water path 3 is formed in the central part 2, or one or plural cooling water paths 4 are spirally formed by disposing partition walls 4 thereto. The water-cooling roll, having excellent overall heat transfer coefft, high cooling rate, and high cooling capacity, is comparatively small in roll-contacting length. Also, the necessary numbers of the roll are saved.
