Abstract
There is disclosed a metallurgical vessel, such as a steelworks converter, having a refractory brick lining and a probe opening passing a wall of the vessel for introducing a measuring and/or sampling probe. In order that the probe opening will get obstructed only minimally, if at all, and possible deposits of slag will be removed easily and quickly, the probe opening is provided with a lining of graphite or a graphite/alumina mixture.
