The melt vessels, such as steel melt ladles (2) are each selectively movable to a casting station and each includes a sliding gate valve (10) connected to a reduction gear (11). Each reduction gear (11) is connected on its input side to a first rotary coupling member (12) and the installation further includes a single rotary drive unit (20) connected to an extensible universal- jointed shaft (22) which in turn is connected to a second rotary coupling member (24). The coupling member (24) is readily releasably securable to any one of the coupling members (12) and thus the single motor can operate all the sliding gate valves one after the other. Where the melt vessels always adopt substantially the same casting position, the drive unit (20) may be fixedly mounted at the casting station (Fig. 1) or, where the vessels are moved successively into different casting positions, supported by the melt vessel (Fig. 2). <IMAGE> |
