Abstract: Pressing device for a casting pipe at the spout of a metallurgical container, wherein the pressing device is provided with spring-loaded pressing elements that can be pressed against guide surfaces of a casting pipe. The casting pipe includes a tubular part and an upper plate. The guide surfaces are arranged on the underside of the plate on both sides of the tubular part and are directed downward at an angle. They form a plate cross-section that is tapered downward. The pressing elements are each provided with a head that is convexly curved in the adjustment direction of the casting pipe and can be pressed against a guide surface of the casting pipe, which is curved in the longitudinal direction of the pressing element or in the adjustment direction. Compressive forces exerted by the pressing pins are optimally transmitted, more toward the casting pipe opening and therefore acting more evenly.

Abstract: Sliding closure for a receptacle containing molten metal includes a housing frame that can be fastened to a spout of the receptacle, a first refractory base plate and a sliding unit having a refractory sliding plate that is sealingly pressed against the first base plate by spring elements and a contiguous refractory spout sleeve contained in the housing frame. The case has a second base plate juxtaposed to the first base plate and displaceable inside the housing frame at a right angle to the direction of movement of the sliding unit from an initial position in which the first base plate is in an operating position towards a final position in which the second base plate is in the operating position. It is therefore possible to replace the base plate, which wears outs quickly, by a new base plate in a rapid and convenient manner without interrupting the casting operation.

Abstract: A fireproof unit for a sliding closure at the spout of a container containing metal melt, including a fireproof adapter block that can be placed on the container spout, a fireproof bottom plate connected thereto, to which bottom plate a slidable fireproof sliding plate can be connected, wherein the sliding plate allows the sliding closure to be opened or closed. In addition to the first bottom plate connected to the adapter block, a second bottom plate adjoins the adapter block. The second bottom plate can be slid in under the adapter block to replace the first bottom plate. The adapter block has a length in the direction of the second bottom plate such that the adapter block is in sliding contact with the second bottom plate at the lower sliding surface of the adapter block.

Abstract: The invention relates to a sliding closure (1) for a metallurgical container, comprising two fireproof closing plates (3; 5), of which one is arranged in a slide unit (6) and is used to open and close a spout opening (10). The other closing plate (3) is arranged in a metal housing (2) that can be fastened to the container. Said stationary housing (2) and the slide unit (6) also accommodate an upper fireproof inlet sleeve (4) on the container side and a lower fireproof spout sleeve (8). In the housing (2) and in the slide unit (6), at least one additional inner part (2a, 2a?, 7a) is arranged in each case, each additional inner part enclosing the spout sleeve (8) or the inlet sleeve (4). Thus, thermal stresses in the slide unit or in the housing can be reduced and the risk of cracks forming can be significantly reduced.

Abstract: A closing plate for a sliding closure on the spout of a receptacle for molten metal, especially of a converter, includes an elongate refractory plate and a sheet metal jacket surrounding the same. The refractory plate has a sliding surface which can be braced with a sliding surface of a refractory closure plate interacting therewith or with a sliding surface of a refractory head part. The refractory plate has at least one tapering section which forms an angle with the sliding surface on at least one side delimiting the sliding surface, each tapering section being associated with a section of the refractory plate that projects beyond the sheet metal jacket. The closing plate reduces the risk of damage to the front faces of the refractory parts reduced during bracing of the parts with each other and/or during a relative adjustment of the refractory parts that are braced with each other.
