Abstract

UN JET DE METAL EST PROTEGE DE LA CONTAMINATION ATMOSPHERIQUE AU COURS DE LA COULEE EN L'ENVELOPPANT AVEC UN GAZ INERTE PROVENANT D'UNE SOURCE DE GAZ SITUEE A L'EMPLACEMENT DE LA TUYERE DE COULEE. LE GAZ EST DISTRIBUE DANS UNE ZONE A FAIBLE TURBULENCE A L'EMPLACEMENT DE LA TUYERE14, ZONE QUI PRESENTE UNE LARGEUR QUI EST D'AU MOINS UN TIERS DE LA LONGUEUR DU JET19 DE METAL COULE. LA SOURCE DE GAZ PEUT ETRE UNE COURONNE22 DISPOSEE AUTOUR DE LA TUYERE ET DONT LES SURFACES DIRIGEES VERS L'INTERIEUR ET VERS LE BAS SONT CONSTITUEES DE TOLES DE METAL PERFOREES, LES SURFACES EXTERNES POUVANT ETRE REMPLACEES AFIN DE POUVOIR TOLERER LES ECLABOUSSURES DE METAL. ON EVITE AINSI LA NECESSITE D'UTILISER UN TUBE POUR ENFERMER LE GAZ PROTECTEUR.
