Le filtre en c\u00e9ramique expans\u00e9e est utilis\u00e9 dans les fonderies de m\u00e9taux et constitue un nouveau type de filtre pour m\u00e9taux en fusion, mis au point pour r\u00e9duire les d\u00e9fauts de coul\u00e9e.<\/p>\n

Le filtre de fonderie est utilis\u00e9 dans le processus de coul\u00e9e de l'aluminium afin d'emp\u00eacher les scories en fusion et autres inclusions nocives de p\u00e9n\u00e9trer dans le moule et, \u00e0 terme, de se retrouver dans la pi\u00e8ce moul\u00e9e finale. Le filtre en mousse c\u00e9ramique d'alumine est sp\u00e9cialement con\u00e7u pour filtrer les impuret\u00e9s pr\u00e9sentes dans l'aluminium en fusion et les alliages d'aluminium.<\/p>\n

Filtres en mousse c\u00e9ramique pour la fonderie<\/a> Gr\u00e2ce \u00e0 leur excellente r\u00e9sistance \u00e0 l'\u00e9rosion et \u00e0 la corrosion caus\u00e9es par l'aluminium fondu, ils permettent d'\u00e9liminer efficacement les inclusions, de r\u00e9duire les gaz pi\u00e9g\u00e9s et d'assurer un \u00e9coulement laminaire, ce qui rend le m\u00e9tal filtr\u00e9 plus pur. Des m\u00e9taux plus purs permettent d'obtenir des pi\u00e8ces moul\u00e9es de meilleure qualit\u00e9, de r\u00e9duire les rebuts et de limiter les d\u00e9fauts dus aux inclusions, autant d'\u00e9l\u00e9ments qui contribuent \u00e0 augmenter les b\u00e9n\u00e9fices.<\/p>\n

Le r\u00f4le du filtre en mousse c\u00e9ramique Casthouse<\/strong><\/p>\n

1. Les c\u00e9ramiques expans\u00e9es pr\u00e9sentent une r\u00e9sistance m\u00e9canique \u00e9lev\u00e9e, une grande stabilit\u00e9 chimique, ainsi qu'une forte r\u00e9sistance aux chocs thermiques et aux chocs li\u00e9s \u00e0 l'\u00e9coulement de m\u00e9taux liquides, m\u00eame dans des environnements \u00e0 haute temp\u00e9rature.
\n2. Am\u00e9liorer la densit\u00e9 et l'\u00e9tanch\u00e9it\u00e9 de la pi\u00e8ce moul\u00e9e, augmenter son allongement et sa r\u00e9sistance \u00e0 la traction, am\u00e9liorer son \u00e9tat de surface, am\u00e9liorer la fluidit\u00e9 du m\u00e9tal en fusion et augmenter la capacit\u00e9 de remplissage et de r\u00e9g\u00e9n\u00e9ration de la masse fondue.
\n3. Simplifier le syst\u00e8me de moulage, r\u00e9duire la longueur des canaux lat\u00e9raux et augmenter le rendement des pi\u00e8ces moul\u00e9es.
\n4. R\u00e9duire la dur\u00e9e d'usinage et l'usure des outils, et am\u00e9liorer la qualit\u00e9 de surface des pi\u00e8ces moul\u00e9es.
\n5. R\u00e9duire la teneur en gaz et en inclusions des pi\u00e8ces moul\u00e9es, r\u00e9duire la turbulence du m\u00e9tal en fusion lors du remplissage du moule, r\u00e9duire les d\u00e9fauts de surface des pi\u00e8ces moul\u00e9es et r\u00e9duire consid\u00e9rablement le taux de rebut des pi\u00e8ces moul\u00e9es.
\n6. Aucune inclusion de scories ni aucune rupture ne se produit au cours du processus de fabrication, ce qui garantit la stabilit\u00e9 de la qualit\u00e9 et de la composition chimique du m\u00e9tal en fusion.
\n7. Gr\u00e2ce \u00e0 un d\u00e9bit de m\u00e9tal important et stable, m\u00eame si la teneur en inclusions du m\u00e9tal en fusion est \u00e9lev\u00e9e, le filtre en c\u00e9ramique alv\u00e9ol\u00e9e ne se colmate pas.
\n8. Gr\u00e2ce \u00e0 sa grande pr\u00e9cision dimensionnelle, il peut \u00eatre int\u00e9gr\u00e9 automatiquement \u00e0 la cha\u00eene de production.<\/p>","protected":false},"excerpt":{"rendered":"
