Abstract

Verfahren zur Erhöhung der Eindringtiefe eines mit einem Volumsstrom und einem Massestrom in die Schüttung eines Roheisenerzeugungsaggregates, bevorzugterweise eines Schmelzreduktionsaggregates/Einschmelzvergasers oder eines sauerstoffblasenden Hochofens, eintretenden Sauerstoffstrahles von technisch reinem Sauerstoff zur Vergasung von in der Schüttung vorhandenen Kohlenstoffträgern, dadurch gekennzeichnet, dass das Verhältnis Volumsstrom zu Massestrom des Sauerstoffstrahles vergrößert wird.
