Abstract

L'INVENTION CONCERNE UNE TUYERE DE BRASSAGE DESTINEE A ETRE MONTEE SUR UN RECIPIENT DE TRAITEMENT METALLURGIQUE POUR ALIMENTER EN GAZ DE BARBOTAGE UN BAIN DE METAL LIQUIDE. CETTE TUYERE EST CONSTITUEE PAR UN RECIPIENT METALLIQUE CREUX DE FORME TRONCONIQUE1 FERME PAR UN COUVERCLE2 POURVU D'UNE ARRIVEE3 DE GAZ DE BARBOTAGE, EST DESTINE A RECEVOIR UN BOUCHON4 EN MATERIAU REFRACTAIRE RESISTANT, ET SUR LA SURFACE INTERNE DE CE RECIPIENT SONT SOLIDARISES DES ELEMENTS D'ESPACEMENT DESTINES D'UNE PART A CENTRER LEDIT BOUCHON REFRACTAIRE ET CONFORMES D'AUTRE PART POUR MAINTENIR UN CERTAIN JEU ENTRE LEDIT BOUCHON REFRACTAIRE ET LE RECIPIENT METALLIQUE TRONCONIQUE, MENAGEANT AINSI UN TRAJET PREFERENTIEL POUR UN CERTAIN FLUX DE GAZ DE BARBOTAGE. APPLICATION A LA METALLURGIE.
