Further, when the top end of the projection and the bottom of the groove, and the side of the projection and the side of the groove are constructed as sliding surfaces respectively, both the thrust and the radial loads can be supported simultaneously.      Further, the planes formed at the rotary ring and the fixed ring are constructed as sliding surfaces respectively, the thrust load is can be supported by said planes. The radial load can be supported by the projection and the side of the groove.       Further, since the center of the groove and the projection are allowed to correspond to the axial center respectively, the axial fluctiation of the center with respect to the fixed ring can be prevented.

Abstract: Method and apparatus for casting metal strip in which molten metal is introduced between a pair of parallel casting rollers (16) via a tundish (18) and metal delivery nozzle (19). Casting rollers (16) are cooled so that shells solidify on the moving roller surfaces and are brought together at the nip between them to produce a solidified strip product (20) at the roller outlet. The tundish (18), delivery nozzle (19) and a pair of side closure plates (56) to confine the pool of metal on the casting rollers are separately preheated to working temperature and then rapidly brought into an operative assembly and casting is started before detrimental uneven or localized cooling of the preheated components can develop. To this end the casting rollers are mounted on a carriage (13) movable between a first station (14) at which the preheated components are fitted and a second station (15) at which casting is carried out.
