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.
