Le flux de recouvrement sert \u00e0 emp\u00eacher l'oxydation de l'aluminium \u00e0 l'int\u00e9rieur du four, ce qui permet de r\u00e9duire les pertes dues \u00e0 l'oxydation et \u00e0 la combustion.<\/p>\n

Nous proposons deux types de produits : le mod\u00e8le 550CF au sodium et le mod\u00e8le 580CF sans sodium.<\/p>\n

La version sans sodium est sp\u00e9cialement destin\u00e9e aux alliages magn\u00e9sium-aluminium et aux alliages d'aluminium modifi\u00e9s au strontium.<\/p>\n

Type contenant du sodium, utilis\u00e9 pour le rev\u00eatement de four d'alliages d'aluminium et d'alliages d'aluminium \u00e0 faible teneur en magn\u00e9sium, afin d'emp\u00eacher l'oxydation et l'absorption d'oxyg\u00e8ne \u00e0 la surface du bain fondu, et de r\u00e9duire les pertes par oxydation. Type sans sodium, utilis\u00e9 pour le rev\u00eatement de four d'alliages d'aluminium \u00e0 forte teneur en magn\u00e9sium et d'alliages d'aluminium modifi\u00e9s au strontium, afin d'emp\u00eacher l'oxydation et l'absorption d'oxyg\u00e8ne \u00e0 la surface du bain fondu, et de r\u00e9duire consid\u00e9rablement les pertes de m\u00e9tal caus\u00e9es par l'oxydation de la surface du bain fondu.<\/p>\n

\"Flux<\/p>\n

Le flux AdTech est une poudre blanche compos\u00e9e de fines particules de sels de chlorure, de fluorure et d\u2019autres compos\u00e9s. Il peut \u00eatre pulv\u00e9ris\u00e9 \u00e0 l\u2019aide d\u2019un gaz dans une cuve d\u2019affinage, ou directement sur la surface du m\u00e9tal en fusion afin d\u2019assurer un brassage homog\u00e8ne et de favoriser la s\u00e9paration des impuret\u00e9s. Il est utilis\u00e9 pour recouvrir le four contenant de l\u2019aluminium et des alliages d\u2019aluminium \u00e0 faible teneur en magn\u00e9sium ou des alliages d\u2019aluminium modifi\u00e9s au strontium, ce qui r\u00e9duit consid\u00e9rablement la perte de m\u00e9tal due \u00e0 l\u2019oxydation de la surface du bain, diminue les pertes par combustion due \u00e0 l\u2019oxydation et forme une barri\u00e8re physique entre l\u2019aluminium fondu et les gaz d\u2019oxydation pr\u00e9sents dans le four. Il permet de r\u00e9duire la formation d\u2019inclusions oxyd\u00e9es dans l\u2019aluminium fondu, produit un effet d\u2019isolation et contribue \u00e0 am\u00e9liorer la qualit\u00e9 de la coul\u00e9e. Il permet de produire des pi\u00e8ces moul\u00e9es de pr\u00e9cision en alliage d\u2019aluminium \u00e0 forte valeur ajout\u00e9e et aux performances techniques \u00e9lev\u00e9es pour l\u2019a\u00e9ronautique et les transports.<\/p>\n

AdTech flux de d\u00e9carburation<\/a> Il s'agit d'une poudre blanche compos\u00e9e de particules fines, dont les principaux composants sont des sels de chlore et de fluor, ainsi que d'autres compos\u00e9s. Ce produit est respectueux de l'environnement et \u00e9conomique, et r\u00e9pond aux exigences requises pour la production de pi\u00e8ces moul\u00e9es de pr\u00e9cision en alliage d'aluminium de haute technologie et \u00e0 forte valeur ajout\u00e9e, destin\u00e9es aux secteurs de l'a\u00e9ronautique et des transports. Nous proposons deux r\u00e9f\u00e9rences : 622DF et 633DF.<\/p>\n

Le flux de d\u00e9sscorification AdTech permet de r\u00e9duire la fum\u00e9e et les pertes \u00e0 la combustion ; l'effet est significatif, et la quantit\u00e9 d'aluminium fondu \u00e9vacu\u00e9e lors de la scorification est consid\u00e9rablement r\u00e9duite.<\/p>","protected":false},"excerpt":{"rendered":"
