An arrangement for introducing and removing a lance into and out of a tiltable metallurgical vessel has drive means stationarily arranged in the direction of the lance axis and means for pivotal mounting of the drive means. The lance is designed as a guide and is guided by the drive means and is movable in the direction of its axis. In a method using the above arrangement for positioning the lance relative to the metallurgical vessel, the actual position of the vessel is taken up by a position transmitter on said vessel, and the drive means is actuated to position the lance in dependence on that actual position.
