A BOF process in which iron oxide units are added to the melt during the blow characterized in that the oxygen flow is reduced during pellet feeding and is replenished with inert gas so that the total gas flow remains the same as that designed to achieve optimum BOF performance.
Divulgation d'un processus de convertisseur à oxygène (BOF) selon lequel des unités d'oxyde de fer sont ajoutées aux produits fondus pendant la décharge caractérisée par le fait que le courant d'oxygène est réduit durant l'alimentation en granulés et est reconstitué avec du gaz inerte de sorte que le courant de gaz total demeure le même que celui conçu pour obtenir la performance optimale du processus BOF.
