Abstract

L'invention concerne le réglage du soufflage d'oxygène dans un convertisseur L-D. Elle se rapporte au réglage de la formation de laitier et à la prédiction des projections assurés par mesure de l'accélération, dans un plan horizontal, d'un détecteur tel qu'une lance de soufflage d'oxygène. Seule l'accélératin due au laitier est prise en considération et les valeurs obtenues sont intégrées sur de petits intervalles et le réglage est effectué en fonction de l'amplitude des valeurs intégrées. Application à l'affinage de la fonte à l'oxygène.
