La purification par filtration CFF consiste \u00e0 \u00e9liminer, \u00e0 l'aide d'un milieu filtrant, les grosses inclusions et certaines inclusions fines en suspension pr\u00e9sentes dans l'aluminium fondu, \u00e0 r\u00e9duire la teneur en gaz de l'aluminium fondu, \u00e0 \u00e9liminer certains \u00e9l\u00e9ments nocifs qu'il contient, ainsi qu'\u00e0 modifier ses propri\u00e9t\u00e9s physiques et ses caract\u00e9ristiques de solidification. La purification par filtration CFF est une technologie visant \u00e0 am\u00e9liorer les propri\u00e9t\u00e9s m\u00e9caniques de l\u2019aluminium. \u00c0 l\u2019heure actuelle, la filtration CFF (filtre en mousse c\u00e9ramique) est la technologie la plus efficace et la plus largement utilis\u00e9e dans le domaine de la filtration et de la purification.<\/p>\n

Le filtre en mousse c\u00e9ramique<\/a> Il s'agit d'une structure en r\u00e9seau tridimensionnelle continue compos\u00e9e de squelettes ramifi\u00e9s en c\u00e9ramique fine. Le m\u00e9canisme de filtrage comporte trois aspects :<\/p>\n

1. Des particules de d\u00e9bris se logent dans chaque orifice de la plaque filtrante et, \u00e0 certains endroits, s'accumulent m\u00eame pour former un \u201c g\u00e2teau de filtration \u201d, lequel peut retenir certaines inclusions plus fines.<\/p>\n

2. Lorsque le m\u00e9tal en fusion traverse la plaque filtrante, en raison des canaux sinueux pr\u00e9sents \u00e0 l'int\u00e9rieur de celle-ci, le d\u00e9bit du m\u00e9tal en fusion varie consid\u00e9rablement, et certaines particules d'impuret\u00e9s de tr\u00e8s petite taille se d\u00e9posent dans certains recoins de la plaque filtrante.<\/p>\n

3. En effet, la structure du filtre pr\u00e9sente une tr\u00e8s grande surface, et la structure c\u00e9ramique elle-m\u00eame est \u00e9galement un corps c\u00e9ramique poreux comportant \u00e0 l'int\u00e9rieur des pores et des microcanaux interconnect\u00e9s. La surface c\u00e9ramique n'est pas mouill\u00e9e par le m\u00e9tal en fusion et poss\u00e8de une forte capacit\u00e9 d'adsorption, ce qui lui permet d'absorber les inclusions pr\u00e9sentes dans l'alliage qui ne sont pas mouill\u00e9es par le m\u00e9tal en fusion.<\/p>\n

L'effet combin\u00e9 des trois m\u00e9canismes susmentionn\u00e9s permet non seulement d'\u00e9liminer les fines particules d'inclusions de 10 \u00e0 20 \u00b5m pr\u00e9sentes dans la masse d'aluminium en fusion, mais aussi d'\u00e9liminer les inclusions de flux liquides et certains \u00e9l\u00e9ments m\u00e9talliques nocifs difficiles \u00e0 retenir avec des m\u00e9dias filtrants ordinaires.<\/p>\n

\"Syst\u00e8me<\/p>\n

Lorsqu'elle est en service, la plaque filtrante en c\u00e9ramique alv\u00e9ol\u00e9e assure la filtration de l'aluminium en fusion ; elle est install\u00e9e sur la ligne de production de coul\u00e9e semi-continue ou de coul\u00e9e et de laminage en continu.<\/p>\n

Par cons\u00e9quent, la plaque filtrante en c\u00e9ramique alv\u00e9ol\u00e9e doit pr\u00e9senter les caract\u00e9ristiques suivantes :<\/p>\n

1. Pr\u00e9senter une r\u00e9sistance m\u00e9canique suffisante ;
\n2. Il pr\u00e9sente une grande r\u00e9sistance aux chocs thermiques et d'excellentes performances de nettoyage ;
\n3. Pr\u00e9senter une porosit\u00e9 et une perm\u00e9abilit\u00e9 au m\u00e9tal en fusion suffisantes ;
\n4. Pr\u00e9sente des propri\u00e9t\u00e9s de d\u00e9gagement de gaz extr\u00eamement faibles ;
\n5. Il pr\u00e9sente une grande stabilit\u00e9 chimique.<\/p>\n

Dans le cadre du processus de moulage, les plaques filtrantes en c\u00e9ramique alv\u00e9ol\u00e9e doivent \u00eatre choisies en fonction des diff\u00e9rents degr\u00e9s de pr\u00e9cision de filtration, des diff\u00e9rentes tailles de particules et des diff\u00e9rents d\u00e9bits. Dans des conditions normales, la plaque filtrante en c\u00e9ramique alv\u00e9ol\u00e9e de 30 PPI r\u00e9pond aux exigences.<\/p>","protected":false},"excerpt":{"rendered":"
