Zusammenfassung:	A blowing method for producing steel from molten raw iron in converters. At least one jet of hot air is sprayed from at least one nozzle of at least one spraying device into the converter chamber onto the molten raw iron. The hot air exiting in the form of a jet has a pressure difference ranging from 0.05-0.1 Mpa between the inlet into the nozzle and the outlet out of the nozzle.
