Abstract (en)

[origin: WO2012136698A1] The present invention relates to a method for operating at least one supersonic nozzle (40) in a metallurgical vessel (3), comprising the following steps: measuring the inlet pressure (po(t)) of a gas into a supersonic nozzle (40); simultaneously measuring the feed pressure (pvs(t)) of the gas at a gas feed station (1) arranged at a distance from the supersonic nozzle (40); determining a calibration curve (po(t)=f(pvs(t))) from the measured inlet pressure (po(t)) and the measured feed pressure (pvs(t)); and operating the supersonic nozzle (40) in the metallurgical vessel at a predefined inlet pressure (po) by regulating the feed pressure (pvs) on the basis of the determined calibration curve.
