ABSTRACT:
A ferrous substance such as iron scrap, powder or sponge, carbon, and a substance forming slag are heated in a rotary converter having an inclined axis and an upwardly facing opening. The charge thus formed in the converter is heated by a burner pointing towards the interior converter base. A complementary injection of industrially pure oxygen is provided in the zone of the flame, the total quantity of oxygen injected being such that the ratio ##EQU1## in the fumes is at least equal to 0.8.
