Abstract

L'invention concerne un procédé et un dispositif pour traiter des métaux fondus, notamment des aciers liquides, au moyen d'un agent d'affinage fait d'oxygène. L'invention vise à augmenter le rendement de l'affinage de l'acier. A cet effet, on utilise un jet d'oxygène liquide enveloppé d'un filet d'oxygène gazeux.
