A drum sleeve 10 removably fitted to the outer peripheral portion of the drum body 11; and a pair of wedge rings 12A, 12B inserted into and joined to the joining ends of the two 10, 11 to fix the two. And a pressing ring 13 fixed to both end surfaces of the drum body 11 and pressing one wedge ring 12B.

た。However, in the structure shown in FIG. 9, slippage is restricted by restricting the axial elongation due to thermal deformation during casting of the drum sleeve 10 only by the frictional force of the wedge rings 12A and 12B. The drum sleeve 10 extends in the axial direction, and there is no guarantee that the drum sleeve 10 will extend symmetrically in the axial direction with respect to the center of the drum. Therefore, there is no axial displacement between the ends of the pair of cooling drums 1 and 1. As a result, there is a problem that the molten metal seal between the side weir 2 and the side weir 2 becomes insufficient.

The elongation of the drum sleeve 10 during casting becomes stronger than the frictional force of the joining surface, slips on the mating surface, and the drum sleeve 1
No. 0 is not guaranteed to extend in the axial direction symmetrically with respect to the center. Therefore, even in this structure, an axial displacement occurs between the ends of the pair of cooling drums 1 and 1, and the molten metal seal between the side weir 2 and the molten metal seal is not provided. There were enough problems.

The drum body 11 includes a pair of shaft members 11A integrally formed with the hollow shaft portion 11a and joined to the ends of the drum sleeve 10, and the shaft member 1 positioned between the shaft members 11A.
A core member 11B shrink-fitted to the inner peripheral surface of the drum sleeve 10 without contact with the core member 11B.

Let me. At this time, the interference (by giving a crown) of the shrink fit joint surface at the intermediate portion in the axial direction of the drum is set to about 1.2 times the interference of the end portion.

ずれが無くなる。According to the cooling drum 1 of the drum type continuous casting machine configured as described above, the drum sleeve 10 and the core member 11B are joined by the shrink fit 15.
Shear stress increases due to a difference in thermal expansion between the drum sleeve 10 and the core member 11B during casting, and the joining surface slips. However, in this structure, the core member 11B and the pair of shaft members 11A are separate and non-contact, and the fitting surface length of the shaft member 11A is shortened. The surface pressure distribution p appears, and the shaft member 11A
The inner side (the middle side in the drum axis direction) slips, and the outer side does not slip. Thereby, relative displacement in the axial direction of the drum end surface with respect to the bearing of the pair of cooling drums 1 is eliminated.

Since the interference of the joining surface at the intermediate portion in the drum axis direction of B is about 1.2 times the interference of the end, the surface pressure resistance at the intermediate portion is larger than that at the end, so that no slip occurs. Both ends of the drum sleeve 10 and the core member 11B slide slightly with each rotation of the drum with respect to the intermediate portion, so that large movement of the entire core member 11B does not occur.
