Abstract (en)
The handling device (26'') comprises a unit (28, 30) for maintaining a jet protection pipe in downstream from a metal casting regulation valve, and a unit for attachment to a valve driving unit. The valve has an open configuration and a closed configuration under the action of the driving unit. Fastening units are arranged so that the handling device follows a movement imposed by the driving unit on the valve. A unit comprising a rotative motor is arranged with driving unit for controlling the pipe. The driving unit comprises a hydraulic cylinder (22) and a rod (24) sliding in the cylinder.

The valve has an open configuration and a closed configuration under the action of the driving unit. Fastening units are arranged so that the handling device follows a movement imposed by the driving unit on the valve. A unit comprising a rotative motor is arranged with driving unit for controlling the pipe. The driving unit comprises a hydraulic cylinder (22) and a rod (24) sliding in the cylinder. The pipe control unit and driving unit are connected around the cylinder by a piece, which is displaced with the rod. The maintenance unit has a flow position and stop position, where the displacement between the two positions has a U trajectory, and comprises a grip tube in the form of a spoon provided with a receiving slot tube and a release tube and valve e.g. arm 63. Independent claims are included for: (1) a jet protection pipe for a flow of liquid metal from a casting ladle towards a metal distributor; and (2) a device for driving the regulation of valve for the flow of liquid metal.
