Abstract

In a method of determination of the end point during oxygen steelmaking in a converter, it is proposed according to the invention that, during the conversion, waste gas constituents continuously escaping from the converter are analysed, preferably by mass spectrometry, and parameters are generated, from the measured values, whose significant change in time gives a signal for ending the oxygen feed.
