Filtre en mousse c\u00e9ramique d'Al\u2082O\u2083<\/a> Ce nouveau type de filtre pour aluminium fondu a \u00e9t\u00e9 mis au point ces derni\u00e8res ann\u00e9es dans le but de r\u00e9duire les d\u00e9fauts de coul\u00e9e. Il se caract\u00e9rise par sa l\u00e9g\u00e8ret\u00e9, sa grande r\u00e9sistance m\u00e9canique, sa grande surface sp\u00e9cifique et sa porosit\u00e9 \u00e9lev\u00e9e. Il pr\u00e9sente en outre une excellente r\u00e9sistance aux agressions et \u00e0 la corrosion caus\u00e9es par l'aluminium fondu.<\/p>\nLe filtre en mousse c\u00e9ramique permet d'\u00e9liminer efficacement les inclusions, de r\u00e9duire la quantit\u00e9 de gaz pi\u00e9g\u00e9 dans l'aluminium liquide et d'assurer un \u00e9coulement laminaire, ce qui rend le m\u00e9tal filtr\u00e9 nettement plus pur. Un aluminium plus pur se traduit par des pi\u00e8ces moul\u00e9es de meilleure qualit\u00e9, moins de rebuts et moins de d\u00e9fauts dus aux inclusions, autant d'\u00e9l\u00e9ments qui contribuent \u00e0 l'am\u00e9lioration du r\u00e9sultat net.<\/p>\n
Les filtres c\u00e9ramiques Adtech utilis\u00e9s dans la fonderie permettent de r\u00e9duire les pores de coul\u00e9e, de limiter les coul\u00e9es de fil, de diminuer les d\u00e9fauts de surface et, par cons\u00e9quent, d\u2019am\u00e9liorer sensiblement le taux de rendement du produit fini. Ils r\u00e9duisent la dur\u00e9e de fabrication des pi\u00e8ces moul\u00e9es ainsi que les dommages caus\u00e9s aux outils et aux matrices, et am\u00e9liorent la qualit\u00e9 de surface des pi\u00e8ces moul\u00e9es. Ils renforcent la r\u00e9sistance \u00e0 la pression et l\u2019\u00e9tanch\u00e9it\u00e9 \u00e0 l\u2019air des pi\u00e8ces moul\u00e9es, augmentent leur r\u00e9sistance \u00e0 l\u2019allongement et am\u00e9liorent la finesse de surface. Ils r\u00e9pondent aux exigences de conception du syst\u00e8me de coul\u00e9e, r\u00e9duisent la longueur des canaux de coul\u00e9e horizontaux et am\u00e9liorent le rendement technologique de la coul\u00e9e.<\/p>\n
Les filtres en mousse c\u00e9ramique sont disponibles en forme carr\u00e9e ou dans des formes g\u00e9om\u00e9triques sur mesure. Les dimensions vont de 10 mm \u00e0 600 mm, et les \u00e9paisseurs de 10 \u00e0 50 mm. Les porosit\u00e9s les plus courantes sont 10 ppi, 15 ppi, 20 ppi et 25 ppi. Des porosit\u00e9s plus \u00e9lev\u00e9es sont disponibles sur demande. Il est \u00e9galement possible de r\u00e9aliser des filtres sur mesure, d\u00e9coup\u00e9s aux dimensions souhait\u00e9es.<\/p>","protected":false},"excerpt":{"rendered":"
