Abstract

1. Device for introducing powdered reagents into a torpedo ladle (1), containing a lance (2) which is arranged approximately vertically in the torpedo ladle, serves for the pneumatic delivery of the reagents, and at its end which is located in the melt (2) is provided with two outlet nozzles (4, 5) which are arranged approximately horizontally and point in opposite directions, characterised in that the outlet nozzles (4, 5) are rotated by a fixed angle (alpha) between 30 degrees and 60 degrees, preferably approximately 45 degrees, with respect to the longitudinal axis (6) of the torpedo melting ladle (1).
