Abstract
Cooling rolls which receive a falling stream of a metal melt, and rapidly cooling and solidifying it. Each of the cooling rolls comprises a roll base body and a sleeve which is fitted around a barrel periphery of the roll base body and forms a cooling water flow path between the roll base body and the sleeve. The sleeve is only partially tightly fixed to the roll base body. End portions of the sleeve are joined to the roll base body in such a soft structure that movement of the sleeve in the roll axial direction due to the thermal expansion is not interrupted at end portions of the sleeve.
