Abstract

PROCEDE D'ARRET DU DEBORDEMENT DE L'EMULSION PAR LE BEC D'UN CONVERTISSEUR D'AFFINAGE A L'OXYGENE. LE DEBORDEMENT EST EMPECHE PENDANT L'AFFINAGE A L'OXYGENE PAR INTRODUCTION DE GAZ INERTE DANS LE CONVERTISSEUR LORSQUE CE DEBORDEMENT EST IMINENT OU A DEBUTE. UN MODE DE MISE EN OEUVRE AVANTAGEUX CONSISTE A INJECTER L'ARGON EN MELANGE AVEC L'OXYGENE PAR LA LANCE DE SOUFFLAGE A UN DEBIT CORRESPONDANT A5 A 30 DE CELUI DE L'OXYGENE. APPLICATION A L'AFFINAGE DE L'ACIER.
