Process for decarburizing a steel melt in a converter comprises monitoring the temperature in the lance head of the blowing lance using a temperature sensor integrated in the lance head and regulating
this invention concerns a blowing lance and a procedure for the metallurgical treatment of molten steel in a converter with oxygen top blown over the molten steel. In order to monitor the treatment process the intention is for a temperature probe (21) to be integrated into the water-cooled lance head (2) behind the front end of the lance head (11a) and between the cooling chambers (5-10) formed in the lance head (2). The signal lines (26) of this temperature probe run through the lance body (1), more specifically, in a central protective pipe which has no connections to the cooling medium or to the oxygen conducting channels (15, 16, and 17).
