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.

Abstract: In an arrangement for supplying media to a blowing lance for a metallurgical vessel including a blowing lance arranged on a lance carrier, a connection piece of the lance carrier connected to at least one media supply duct is pressable at a counter connection piece of the blowing lance such that the media supply duct is sealingly connectable to a corresponding medium channel of the blowing lance. In order to ensure the tight connection between blowing lance and lance carrier in a sinmple manner and without manual manipulations, a displacement means including a seat for the blowing lance is provided on the lance carrier to move the counter connection piece from a released position into a coupled position and vice versa. The displacement means is movable by a driving device, which presses the counter connection piece against the connection piece in the coupled position, selflockingly and positively fixing the displacement means in the coupled position.

Abstract: A blowing lance to be used for the treatment of metallurgical melts includes a lance head having several expansion tuyeres directed to the bath level of the melt and penetrating a front plate of the lance head. They depart from at least one lance channel, which is peripherally surrounded by a supply channel and a return channel for a cooling medium. The supply channel is separated from the return channel by a flow deflection piece arranged above the front plate and penetrated by at least one connecting channel connecting the supply and return channels and provided for the cooling medium.

Abstract: An arrangement for cleaning a lance head of a lance introducible into a metallurgical vessel includes a cleaning head being in contact with the lance head during the cleaning procedure and surrounding the lance head. The cleaning head and the lance are relatively movable in the direction of the axis of the lance. In order to be able to carefully clean the lance head on its side facing the melt bath present in the metallurgical vessel by preventing the penetration of slag during the measuring procedure between the measuring and/or sampling probe and the end face of the lance, the cleaning head and the lance are placeable into an aligned position by an adjustment device. The cleaning head is settable into a rotational movement reciprocating about the axis of the lance by an oscillation device.

Abstract: In a blowing lance media-supply arrangement for a metallurgical vessel, a carrying car is displaceable into and out of a blowing position along a moving path and includes at least one blowing lance. Media supply conduits lead to the blowing position of the carrying car and are connected to a stationary joining piece arranged there. A joining counter piece corresponding to the joining piece is mounted to the carrying car, and the joining piece and the joining counter piece are connectable in a conduit-like manner.

Abstract: A lining arrangement for metallurgical vessels has a frame, a lifting scaffold arranged thereon comprised of at least two tube elements composed of tube pieces, and a working platform arranged on top of the lifting scaffold. The tube pieces are telescopically movable into one another.
