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.
