Abstract
In an arrangement for supplying steel from a base outlet of an intermediate vessel (2) in a continuous casting installation, the intermediate vessel (2) is provided with an outlet block (3). Beneath the outlet block (3) there is arranged a first change-over part (6) which is movable transversely to the discharge direction (4) and can be pushed out of the casting position by a moving arrangement (30) and a second change-over part (38). An arrangement of this type is to be improved in such a way that the casting nozzle body has a longer service life and is cheaper to produce. Furthermore, security on the casting platform is to be improved during interruptions in casting, the extraction speeds during continuous casting are to be altered and the positional accuracy of the outlet block is to be increased. For this purpose, the change-over part (6) is made up of a holding frame (12) and a casting nozzle body (11). The holding frame (12) is guided and positioned on guide strips (14) in guide rails (7, 7'). In the casting position, the holding frame (12) is connected to a gas circulation system (17), gas inlet apertures (21) on the guide strips (14) being brought into conformity with gas supply apertures (20) on the guide rails (7).
