Abstract

Procédé pour commander le fonctionnement d'un passage d'amenée de fluides au-dessous du niveau d'un bain fondu dans un récipient métallurgique. Le passage d'amenée de fluides comprend au moins deux passages concentriques 16, 18 pour fournir, par le passage central, un fluide oxydant, tel que de l'air ou de l'oxygène, et, par le passage annulaire, un fluide de refroidissement tel que de l'azote. La pression Pa, Pc du fluide dans chaque passage est contrôlée et les débits des fluides sont réglés pour maintenir les pressions à des niveaux optimaux prédéterminés. Application aux récipients d'élaboration de l'acier.A method of controlling the operation of a passage for supplying fluids below the level of a molten bath in a metallurgical vessel. The fluid supply passage comprises at least two concentric passages 16, 18 for supplying, through the central passage, an oxidizing fluid, such as air or oxygen, and, through the annular passage, an oxidizing fluid. cooling such as nitrogen. The pressure Pa, Pc of the fluid in each passage is controlled and the flow rates of the fluids are adjusted to maintain the pressures at predetermined optimum levels. Application to steel production vessels.
