Abstract

PURPOSE:To delay the generation of a heat crack of a caliber corner part, and to improve the service life of a roller by leading cooling water into the inside of the roller and cooling it. CONSTITUTION:A partition plate 4 is pushed and fixed by a bolt 8 between a circulating passage F and G provided on a sleeve 2-1. Cooling water which has circulated from a circulating passage D provided in the radial direction of the end face of the upper side of a roller 1 passes through a circulating passage E provided on the sleeve 2-1, goes into F and makes about one round, and thereafter, led to a circulating passage G for passing through the circulating passage F and H by a weir of the partition plate. Also, said cooling water makes about one round through the circulating passage H, dammed by the partition plate 4, led to a circulating passage I for drainage and discharged from K. In such a way, an L part in which a heating temperature of the roller becomes the highest temperature is cooled first, and subsequently, the surface of a caliber is cooled, by which a service life of the roller can be improved.
