Abstract

Le métal fondu est filtré à l'aide d'un filtre (10, 28, 44) comprenant un substrat de mousse de carbone poreux sensiblement imprégné d'un métal réfractaire ou d'un composé réfractaire formé par dépôt chimique en phase vapeur, et ayant une porosité de filtration inférieure à 90 %, mais, de préférence, d'au moins 75 %, et une fraction solide ligamentaire d'au moins 0,95, au moyen d'un appareil comprenant un récipient (1, 21, 40) destiné à contenir le métal fondu, pourvu d'une entrée (2, 41) et d'une sortie (3, 22, 42), au moins un boîtier de filtre, le ou chaque boîtier renfermant un filtre (10, 28, 44), un dispositif de mise en place et de scellement du ou des filtres (10, 28, 44), et un dispositif (5, 38) permettant de préchauffer le récipient (1, 21, 40) et le ou les filtres (10, 28, 44) préalablement à l'utilisation de l'appareil pour la filtration du métal fondu.
