摘要： PROBLEM TO BE SOLVED: To provide a cooling drum for continuous casting capable of effectively preventing shift caused by the difference between the thermal expansions of a drum sleeve of a cooling drum and the drum body at a joint face such as a shrink fit of the both members during the casting work. SOLUTION: Molton metal 3 is supplied into a pouring basin formed by a pair of cooling drums 1 mutually rotating opposite to each other and side gates 2 and a splidifying shell is formed by cooling the molten metal by bringing it contact with the surface of the cooling drum 1 to cast a thin metal sheet 4, in the cooling drum of the drum type continuous casting machine. The cooling drum 1 is provided with a drum body 11 having a hollow shaft 11a at both side ends and a drum sleeve 10 fitted to the outer periphery of the drum body 1, and many streaks of warm water passageways 30a, 30b extending to the axial center of the drum along the joint face with the drum sleeve 10 at least in the inside of the drum body 11 are formed while separating by a specified distance from each other in the circumferential direction, and cooling water whose temperature is raised by heat exchange at the cooling water holes 22a, 22b of the drum sleeve 10 is led to the warm water passageways 30a, 30b.

摘要： PROBLEM TO BE SOLVED: To provide a casting drum composed of a Cu-alloy made sleeve and an SUS-made core light in weight, free from the sliding of a fitting part in thermal loading, and long in durable life, in a twin drum type continuous casting drum used for twin drum type continuous casting equipment. SOLUTION: By constituting the SUS made core, which is fitted into a Cu- alloy made sleeve, of ring-shaped cores juxtaposed in the axial direction with a space with one another as a plurality of splitted bodies, the sleeve is movable in the axial direction at the part where the core does not exist, and the relative sliding on the fitting part becomes hard to be caused at the part where the core exists owing to that the length in the axial direction of the fitting part of the sleeve and the core is cut to be short, as a result, enabling the tightening force to be small in fitting of the sleeve and the core, which enables the sleeve to be formed thin.
