23843-227 CLOSURE AND/OR CONTROL ELEMENT FOR METALLURGICAL VESSEL ABSTRACT A closure and/or control element for tapping liquid metal melt from a metallurgical vessel including an inner tube and an outer tube is to be tightly closeable even when the gap between the circular cylindrical main sealing surfaces on the tubes becomes widened through use. For this purpose, at least one end surface of the one tube and an end surface of the other tube are opposed to one another. In the event of leakage of the main sealing surfaces, the end surfaces are pressed against one another and form supplementary sealing surfaces.
