Abstract

L'INVENTION CONCERNE LA METALLURGIE. LE PROCEDE FAISANT L'OBJET DE L'INVENTION EST DU TYPE COMPRENANT DES ETAPES D'ASPIRATION ASCENDANTE D'ASPIRATIONASCENDANTE DE PORTIONS DETERMINEES DE METAL 3 DANS UN ESPACE LIMITE 2 SITUE AU-DESSUS DU BAIN DE METAL EN FUSION, ALTERNANT AVEC DES ETAPES D'EJECTION, SOUS L'ACTION D'IMPULSIONS DE GAZ COMPRIME, DES PORTIONS AINSI ASPIREES, AFIN DE LES RESTITUER AUDIT BAIN DE METAL, ET EST CARACTERISE EN CE QUE LESDITES PORTIONS DE METAL SONT ASPIREES DES COUCHES SUPERIEURES DU BAIN DE METAL SITUEES DIRECTEMENT SOUS SA SURFACE LIBRE, ET QUE LESDITES EJECTIONS POUR LA RESTITUTION DESDITES PORTIONS ASPIREES AUX COUCHES SUPERIEURES S'EFFECTUENT DANS LES COUCHES INFERIEURES DU BAIN ADJACENTES A LA SOLE DE LA CUVE DU FOUR 1, LESDITES ASPIRATIONS ET EJECTIONS ALTERNEES DU METAL SE FAISANT DE TELLE FACON QUE, AU FUR ET A MESURE QUE LE NIVEAU DU BAIN DE METAL MONTE, LES PORTIONS SOIENT A CHAQUE FOIS ASPIREES DE LA COUCHE DU BAIN DE METAL IMMEDIATEMENT SOUS-JACENTE A SA SURFACE LIBRE ET QU'ELLES SOIENT EJECTEES PRES DU FOND DE LADITE CUVE. L'INVENTION PERMET D'OBTENIR UNE COMPOSITION CHIMIQUE HOMOGENE DES ALLIAGES ET UN CHAMP DE TEMPERATURE UNIFORME DANS LE BAIN DE METAL.
