\nDescription<\/strong>
\nLa filtration par filtre en mousse c\u00e9ramique (CFF), la filtration par cartouche et le syst\u00e8me DBfilter (PDBF) constituent les trois principaux types de m\u00e9thodes de filtration de l'aluminium. Le dispositif de filtration DBfilter est compos\u00e9 de plusieurs couches de billes d'alumine et d'une couche de gravier d'alumine de taille appropri\u00e9e, empil\u00e9es selon une configuration unique, l'\u00e9paisseur du milieu filtrant atteignant 500 mm. La taille et la m\u00e9thode d'empilement des billes et du gravier d'alumine doivent \u00eatre adapt\u00e9es en fonction des diff\u00e9rents alliages. Les inclusions sont principalement adsorb\u00e9es \u00e0 la surface du milieu de filtration de quatre mani\u00e8res : par interception directe, par mouvement brownien, par force d'inertie et par pr\u00e9cipitation gravitationnelle.<\/p>\n

\n1. La meilleure efficacit\u00e9 de filtration.<\/p>\n

2. Seuls les filtres \u00e0 lit profond peuvent \u00eatre utilis\u00e9s pour filtrer l'aluminium fondu.<\/p>\n

3. Faible co\u00fbt d'exploitation du proc\u00e9d\u00e9 de filtration.<\/p>\n

4. Capacit\u00e9 de filtration maximale.<\/p>\n
