Abstract

L'INVENTION UTILISE AU MOINS UN ELEMENT FILTRANT2 AMOVIBLE EN MOUSSE DE CERAMIQUE DISPOSE DANS UN PASSAGE DE METAL FONDU EN AMONT D'UN MOULE5, SOUS L'ENTONNOIR DE COULEE1 PAR EXEMPLE. CET ELEMENT RETIENT TOUTES LES PARTIES DE PELLICULE D'OXYDE ET PARTICULES ENTRAINEES. LE DEBIT A TRAVERS LE FILTRE2 EST TEL QUE LE FLUX DE METAL APRES CE FILTRE EST TRANQUILLE ET DEPOURVU DE TURBULENCE, CE QUI LIMITE LA CREATION DE NOUVELLES PELLICULES D'OXYDE ET DE PARTICULES A UN MINIMUM. L'INVENTION EST APPLICABLE A DE NOMBREUX MODES DE COULEE, NOTAMMENT D'ALUMINIUM ET SES ALLIAGES.THE INVENTION USES AT LEAST ONE REMOVABLE FILTER2 ELEMENT IN CERAMIC FOAM AVAILABLE IN A MELTED METAL PASSAGE UPSTREAM OF A MOLD5, UNDER THE CASTING FUNNEL1 FOR EXAMPLE. THIS ELEMENT REMAINS ALL PARTS OF OXIDE FILM AND TRAINED PARTICLES. THE FLOW THROUGH FILTER2 IS SUCH THAT THE METAL FLOW AFTER THIS FILTER IS QUIET AND TURBULENT FREE, LIMITING THE CREATION OF NEW OXIDE AND PARTICLE FILMS TO A MINIMUM. THE INVENTION IS APPLICABLE TO A NUMBER OF CASTING MODES, IN PARTICULAR OF ALUMINUM AND ITS ALLOYS.
