LD-KONVERTER MIT NACHVERBRENNUNG

摘要

LD-converter with additional nozzles for the temporary infeed of secondary oxygen intended to the post combustion of CO-containing reaction gas, wherein the additional nozzles (11) are arranged at the lower end of a hollow lance (8) which is concentric with respect to the oxygen blowing lance (5) and are so directed that the jets (12) of secondary oxygen can not impact the wall (2) of the converter (1) or the oxygen blowing lance. The hollow lance (8) is perpendicularly displaceable with respect to the oxygen blowing lance (5).
