A rotary sliding gate, valve for a metallurgical vessel comprises a refractory nozzle brick (4) and a refractory rotary body (15, 16) which sealingly engages it and is rotatable about an axis (17). The passage (8) through the nozzle brick (4) is offset from the axis (17). The rotary body includes a pouring or outlet tube (15) which defines a passage (20) whose axis is coincident with the axis (17) and a flange portion (16) which defines at least one connecting passage (19) of which one end is in communication with the passage (20) in the pouring tube and the other end may be selectively moved into registry with the passage (8) in the nozzle brick. The rotary member (15, 16) is carried by a rotary cage (21). The rotary cage and the rotary member have cooperating, radially extending tongues and grooves (23, 22) which transmit torque from the rotary cage to the rotary member. <IMAGE> |
