Principe de fonctionnement des cartouches\/tubes<\/h3>\n

La filtration sur cartouche est utilis\u00e9e pour la filtration de l'aluminium et des alliages d'aluminium. Son concept technique repose sur le principe de l'\u00e9change thermique : il s'agit de cr\u00e9er la plus grande surface de contact possible dans un espace aussi r\u00e9duit que possible, afin d'obtenir une surface de m\u00e9dia filtrant tr\u00e8s \u00e9tendue. En termes de capacit\u00e9 de filtration du m\u00e9tal en fusion, la surface de contact plus importante offerte par le filtre \u00e0 cartouche permet d'utiliser des m\u00e9dias filtrants plus fins pour un d\u00e9bit de coul\u00e9e donn\u00e9, ce qui am\u00e9liore consid\u00e9rablement l'efficacit\u00e9 de la filtration par rapport \u00e0 d'autres dispositifs de filtration(filtre \u00e0 lit profond<\/a>, filtre \u00e0 plaques<\/a><\/strong>). Le groupe \u00ab Tubular \u00bb, qui offre le niveau de filtration le plus \u00e9lev\u00e9, est th\u00e9oriquement capable d'\u00e9liminer toute l'eau contenant de l'aluminium pur dont les particules d'impuret\u00e9s sont sup\u00e9rieures \u00e0 5 \u03bcm.<\/p>\n

Calcul th\u00e9orique du d\u00e9bit d'un filtre \u00e0 cartouche\/tubulaire :<\/h3>\n

\"\u00c9quipements<\/p>\n

D\u00e9bit des cartouches\/filtres tubulaires (m\u00b3\/h) = nombre de groupes tubulaires * d\u00e9bit par groupe tubulaire * 60 * nombre de groupes tubulaires
\n(Remarque : le d\u00e9bit du filtre tubulaire est choisi en fonction de la pr\u00e9cision de filtration du groupe de filtres tubulaires s\u00e9lectionn\u00e9.)<\/p>\n

Composants de filtres \u00e0 cartouche\/tubulaires<\/h3>\n

La filtration sur cartouche comprend 7 composants principaux :
\n1. Corps du bo\u00eetier : compos\u00e9 principalement d'un rev\u00eatement int\u00e9rieur, d'une couche isolante (papier fibreux, panneau nano, panneau de silicate de calcium, mat\u00e9riau de remplissage isolant et mat\u00e9riau d'\u00e9tanch\u00e9it\u00e9) et d'une enveloppe ; il contient principalement de l'aluminium liquide et un m\u00e9dia filtrant.<\/p>\n

2. Couvercle du caisson : il est principalement compos\u00e9 du mat\u00e9riau du couvercle, d\u2019une couche isolante (papier fibreux, couverture fibreuse, toile en feuille d\u2019aluminium), de clous d\u2019ancrage et d\u2019une bague d\u2019\u00e9tanch\u00e9it\u00e9 en PTFE ; il sert principalement \u00e0 soutenir les \u00e9l\u00e9ments chauffants et les conduits d\u2019air comprim\u00e9, tout en r\u00e9duisant les pertes thermiques de l\u2019aluminium liquide.
\n3 Composants de chauffage : compos\u00e9s principalement de tiges en carbure de silicium, de supports tubulaires pour tiges en carbure de silicium, de thermocouples pour gaz de four, de thermocouples pour aluminium en fusion, etc. ; ils servent principalement \u00e0 chauffer la cuve et \u00e0 garantir que la temp\u00e9rature de l'aluminium en fusion \u00e0 l'int\u00e9rieur de celle-ci r\u00e9ponde aux exigences du processus de production.
\n4 Composants du groupe tubulaire : principalement le groupe tubulaire, le bloc de calage, l'outil de levage du groupe tubulaire et l'outil d'installation du groupe tubulaire.
\n5 Armoire \u00e9lectrique de commande : compos\u00e9e principalement d'un \u00e9cran tactile, d'un automate programmable (PLC), d'un r\u00e9gulateur de puissance, etc. ; elle sert principalement \u00e0 contr\u00f4ler la puissance de chauffage de l'\u00e9l\u00e9ment chauffant en fonction des exigences du four \u00e0 cartouches filtrantes et de la courbe du processus de production<\/p>","protected":false},"excerpt":{"rendered":"
