PROCEDE D'ELABORATION DE LINGOTS PAR COULEE CONTINUE DOUBLE, MACHINE POUR SA MISE EN OEUVRE ET LINGOTS AINSI OBTENUS

LA PRESENTE INVENTION CONCERNE LA METALLURGIE.LE PROCEDE FAISANT L'OBJET DE L'INVENTION EST DU TYPE COMPRENANT L'ADMISSION DE METAL 5 DANS UNE LINGOTIERE 1 DISPOSEE HORIZONTALEMENT ET L'EXTRACTION DES LINGOTS 6 DANS DEUX SENS OPPOSES A TRAVERS LES EXTREMITES DE LADITE LINGOTIERE, CARACTERISE EN CE QUE LE METAL 5 EST ADMIS DANS UNE LINGOTIERE 1 FERMEE SUIVANT TOUT SON PERIMETRE, A TRAVERS UN TROU 2 REALISE DANS SA PAROI, LE MENISQUE DU METAL LIQUIDE 5 ETANT DEPORTE HORS DE LA LINGOTIERE 1 ET A UNE VITESSE EGALE A LA VITESSE INITIALE DE FORMATION DES LINGOTS 6 A L'ENDROIT OU LE METAL 5 EST ADMIS DANS LA LINGOTIERE 1.L'INVENTION PEUT ETRE UTILISEE EN PARTICULIER EN SIDERURGIE ET DANS LA METALLURGIE DES NON-FERREUX. A molten metal (5) is fed into a horizontally arranged mould (1) through an opening (2) made in its wall and cast strands (6) withdrawn from opposite ends of the mould. The meniscus of the liquid metal (5) is disposed outside the mould (1), and the rate of feeding the metal (5) into the mould (1) equals the rate at which the strands (6) are formed at the place where the metal (5) is fed into the mould (1). The mould (1) is mounted for oscillation by means of an appropriate mechanism (10) is tightly connected with a tundish (3) through a metal conduit (4) fitted into the opening (2) made in the wall of the mould (1) and located substantially at an equal distance from its ends. A separating element, provided for setting up the initial casting formation zone is arranged coaxially with the opening (2) inside the mould (1).
