Abstract

Lance for injecting a substance in gas and/or powder form into melts, comprising a metal tube (1) surrounded by a refractory insulation (3), a distributor or spreader arranged as an extension of the metal tube, which spreader is provided with outwardly extending nozzle tubes (11), and which is fixed in a refractory lance head (4), spreader being shaped as a bolt-like body having a flange-like head and a central hollow pin extending into a corresponding central recess in the lance head (4), head being provided with holes evenly distributed around its circumference which holes are connected with the hollowness of the pin and thus the interior of metal tube (1), and in which the nozzle tubes (11) are arranged, and these nozzle tubes (11) being contained in the area between the refractory insulation (3) and the lance head (4) in recesses therein and/or in the insulation (3).
