Abstract

In the pig iron refining operation in a converter working on the top blowing principle, the invention concerns an automatic control process in which the rate of blowing of oxygen into the converter and the temperature of the refining fumes are measured. The lance height is regulated relative to the bath of molten metal according to a predetermined program based on the amount of oxygen blown in. Simultaneously, the blowing rate is regulated in such a manner that the temperature of the fumes follows a predetermined path.
