摘要： A sliding closure (10) at the outlet of a metallurgic container is provided with a housing (12), at least one closing plate arranged therein, a longitudinally displaceable closing plate and a cover (15), fastened to the housing (12) by means of a bracing mechanism (20). The closing plates can be pressed against one another by the bracing mechanism (20) via the cover (15). The bracing mechanism (20) having at least one spring member (33) is provided with clamping levers (21, 22) pivotably housed on either side at the housing (12) and supports (23, 24) which cooperate with same, with the result that, by pivoting these clamping levers (21, 22), the cover (15) can be fastened to, or released from, the housing. In this way, the closing plates, which often need to be exchanged, can also be braced, always uniformly and optimally, against one another, even after many operational uses.

摘要： The invention relates to a sliding closure (10) for a metallurgical vessel comprising a tapping hole (1) for draining metal melt or slag, said sliding closure being provided with a slider housing (3) that can be secured to the vessel (2) and a closure plate (6) that can move therein for opening and closing the tapping hole (1). The sliding closure (10) also has only this moveable closure plate (6), without a stationary closure plate, which is can be moved directly on a sliding surface (7), extending around the tapping hole, preferably of a casing block (9) in the vessel (2) and can be pressed by pretensioning elements. In this way, this sliding closure (10) provides a constructionally simpler structure and user-friendly handling.

摘要： In a device for manipulating preferably a casting tube in a changing device at the spout of a metallurgical vessel, this manipulation is performed by means of a robot having an attachable base, a carrying arm that pivots on the base and at least one extension arm mounted rotatably on the carrying arm and has a gripper, preferably for the casting tube. The base of the robot is attached alongside the vessel such that the carrying arm is pivotable to a side of the vessel into a downwardly directed position and each extension arm is movable along an underside of the vessel. This provides optimum placement of the robot, and consequently the device, so they do not impede access for personnel to the tundish on the casting platform during casting and corresponding manipulations can be carried out easily and operationally reliably with the device in an automated manner.

摘要： Method for automatically replacing the spout nozzle of a slide closure with a robot for manipulating the slide closure with an appropriate apparatus, the spout nozzle being able to be clamped against the slide plate of the slide closure by a carrying ring that can be released by turning. During the changing procedure, the carrying ring is turned with a defined torque, by means of which the new spout nozzle is clamped with a likewise defined tension force against the slide plate. In this way, operational reliability of the slide closure is guaranteed, independently of any tolerance and other deviations. The apparatus for implementing the method includes a gripping lance with clamping jaws for manipulating the spout nozzle and a gripping ring with catches for manipulating the carrying ring. The gripping ring can be actuated by a hydraulic rotation cylinder. A pneumatic cylinder is used to actuate the gripping lance.
