Abstract (en)
[origin: WO03070990A1] A method for decarburisation of molten steel in a RH unit is characterised in that, beginning with the rise in CO released into the vacuum container (2) due to the natural decarburisation as a result of the oxygen dissolved in the steel bath and present in the system, a calculated amount of oxygen is introduced, dependent on the starting carbon content and the starting oxygen content of the melt, whereby a starting pressure for the beginning of the blowing process is calculated depending on the starting carbon content.
