Beschreibung
Zusammenfassung:	The invention relates to a method for producing steel using lump iron carriers in a converter (1). Fuel and oxidizing gas are injected into the hot converter (1) supplied with lump iron carriers through nozzles (4) in the converter base (3), and the hot combustion gases are conducted through the supplied material (12) before molten iron is supplied to the preheated supplied material (12) and the molten iron is refined into steel. For preheating purposes, the converter (1) supplied with lump iron carriers is rotated out of a supply position into a preheating position, in which the converter base (3) points upwards, after the converter opening (8) is closed by a grate (13) before the fuel and the oxidizing gas are injected into the combustion chamber (15) formed above the supplied material (12) through the nozzles (4) and the combustion gases flowing through the supplied material (12) are discharged through the grate (13). After the supplied material (12) is preheated, the converter (1)is returned to the supply
