Slide closure for a metallurgical vessel, with two compensation units I and II for equalizing overloads, which may result from the thermal extension and spreading of the fire-proof closure plate thicknesses conditional on manufacturing, and/or from the upper inner shell, wherein the inner shell can also be reduced during operation. The compensation unit I consists of a spring arrangement with fastening screws which can be moved away between the housing and a cover of the housing. The compensation unit II consists, for its part, of a spring arrangement with an insertion frame pressing against the lower closure plate, which insertion frame is fixed to the bottom of the housing with fastening screws.
A slide closure for a metallurgical vessel, preferably a tundish for a strand casting system, with a housing (4) which can be fastened on to the bottom of the vessel, an upper closure plate (5) arranged in a cover (11) of the housing (4), a lower closure plate (6) and a closure plate (8) which can be longitudinally displaced therebetween, wherein these closure plates (5, 6, 8) are tensioned against one another with spring arrangements extending between the housing (4) and the cover (11), characterized in that the slide closure is provided with a first compensation unit I with spring arrangements (23) for tensioning the closure plates (5, 6, 8) against one another and a second compensation unit II with spring arrangements (30) for pressing the closure plates (5, 6, 8) against the upper inner sleeve (9) with an additional insertion frame (25) arranged in the housing (4), which frame can be pressed against the lower closure plate (6).
