Abstract
Slide closure for a vessel containing molten metal includes a slide housing and a slide unit that can be displaced longitudinally towards the slide housing, at least one refractory closure plate can respectively be inserted into the slide housing. The closure plates can be pressed against one another by the slide unit being braced against the slide housing. The closure plates can respectively be fixed or centered therein by a placement device having a displaceable positioning element. These placement devices are respectively designed such that upon bracing the slide unit against the slide housing, placing of the positioning element and clamping or centering of the respective closure plate is brought about therein. Therefore, despite easier operation, increased operating reliability is guaranteed because the closure plates are clamped and centered mechanically.
