Abstract

PURPOSE:To prolong the life of the roller and prevent the leakage of the cooling water passing the fire cracks produced in a sleeve roll by providing air layers within the sleeve roll on which roll cooling passages are exchangeably put-on the roll body. CONSTITUTION:The sleeve roll 4 which is put on exchangeably on a roll body 1 through shrinkage-fitting or the like consists of a fitting part 5 and build-up weld zone 6. Grooves 9 are spirally formed on the outside peripheral surface of the fitting part 5 and the closing members 12 of the grooves 9 are welded to the bottom side wall of the wide groove part 10 in the radial outward part, whereby cooling passages 13 are formed. Fitting members 15 are welded by welding members 16 into the grooves 10 on the radial outer side of the members 12 to form an air layer 17 of a slight clearance between the members 15, 12. A high-temperature slab is supplied to the outside circumferential surface of the roll roller 22 and cooling water is supplied to the passage 13 through the pipe 20, annular groove 14, etc. As a result of this, the roller 22 is cooled and fire cracks are produced in the weld zones 6. These cracks progress to the inside with lapse of time but are stopped by reaching the air layers 17.
