Title: Method and device for blowing oxygen in metal refining converters in unstationary manner

Abstract: The invention provides variation in the delivery of oxygen to converters for refining metal. Thus, oxygen blowing into such converters in unstationary manners, i.e., varying degrees of pressure and/or flow rate, is performed by means of partialization of the nozzles of the lance heads, or by means of decreases in the penetration capacities of the oxygen jets throughout the blowing process or during a part only of the same resulting in greatly improved reaction rates.
