Les flux de raffinage granulaires AdTech sont sans fum\u00e9e, sans go\u00fbt, sans poussi\u00e8re, faciles \u00e0 utiliser et offrent un bon effet de d\u00e9gazage. Il s'agit d'un d\u00e9poussi\u00e9reur raffin\u00e9 sp\u00e9cial dont le produit est pulv\u00e9ris\u00e9 au fond du bain de fusion par un gaz vecteur (azote ou argon), formant ainsi un grand nombre de bulles dans l'aluminium fondu.<\/p>\n

Les bulles remontent depuis le fond. Le milieu est en contact total avec le m\u00e9tal en fusion, et le gaz ainsi que les inclusions pr\u00e9sents dans l'aluminium en fusion sont amen\u00e9s \u00e0 la surface de celui-ci par des effets physiques et chimiques, ce qui permet d'atteindre simultan\u00e9ment les objectifs de d\u00e9gazage et d'\u00e9limination des scories. Apr\u00e8s de nombreuses applications, cet agent d'affinage s'est r\u00e9v\u00e9l\u00e9 \u00eatre le meilleur choix pour la purification de l'aluminium fondu.<\/p>\n

Mode d'emploi de l'agent d'affinage pour la coul\u00e9e d'aluminium<\/strong><\/p>\n

1. La quantit\u00e9 de pr\u00e9paration raffin\u00e9e est d'environ 0,31 TP3T (cette quantit\u00e9 est d\u00e9termin\u00e9e en fonction de la situation).
\n2. Lors de l'utilisation, verser le produit dans un r\u00e9cipient sp\u00e9cial contenant de l'argon ou de l'azote sec, mettre sous pression et injecter le m\u00e9lange dans l'aluminium en fusion, m\u00e9langer uniform\u00e9ment, arr\u00eater la r\u00e9action, laisser reposer pendant un certain temps, puis proc\u00e9der \u00e0 la coul\u00e9e.
\n3. Saupoudrez la poudre fine d'aluminium moul\u00e9 \u00e0 la surface du liquide et enfoncez-la rapidement dans l'aluminium en fusion. Apr\u00e8s avoir bien m\u00e9lang\u00e9, laissez reposer puis \u00e9gouttez. Il est pr\u00e9f\u00e9rable d'injecter l'agent d'affinage dans l'aluminium en fusion \u00e0 l'aide d'un gaz inerte.
\n4. Appuyez sur la touche agent d'affinage de l'aluminium moul\u00e9<\/a> au fond de la masse d'aluminium fondu. \u00c0 ce stade, en raison de la forte chaleur d\u00e9gag\u00e9e par la r\u00e9action, l'aluminium fondu devient rapidement rouge sous l'effet de la chaleur. L'agent d'affinage doit \u00eatre en contact total avec l'aluminium fondu.<\/p>\n

Avantages des flux de raffinage granulaires<\/strong><\/p>\n

1. En s'appuyant sur le principe de l'association de compos\u00e9s m\u00e9talliques et liquides, d\u00e9velopper et concevoir des produits permettant de r\u00e9duire la fum\u00e9e et la poussi\u00e8re, de limiter la combustion, tout en \u00e9tant respectueux de l'environnement et \u00e9conomiques.
\n2. Le probl\u00e8me li\u00e9 \u00e0 l'effet d'affinage r\u00e9sultant de l'utilisation traditionnelle de grandes quantit\u00e9s de cendres d'aluminium est r\u00e9solu. La dose d'agent d'affinage AdTech est comprise entre 1,5 et 2,0 kg par tonne d'aluminium, et la teneur en cendres d'aluminium est comprise entre 0,8 et 1%, ce qui r\u00e9pond aux exigences de la coul\u00e9e d'alliages d'aluminium de haute pr\u00e9cision. Il permet d'augmenter efficacement le rendement en m\u00e9tal fondu de 0,6 \u00e0 0,81 TP3T, tout en r\u00e9alisant des \u00e9conomies d'\u00e9nergie et une r\u00e9duction de la consommation.
\n3. Apr\u00e8s un traitement thermique et un tamisage appropri\u00e9s, la granulom\u00e9trie uniforme permet au m\u00e9tal de p\u00e9n\u00e9trer de mani\u00e8re homog\u00e8ne dans la couche inf\u00e9rieure de l'aluminium fondu sous l'action du gaz vecteur (N\u2082 ou Ar), ce qui r\u00e9sout compl\u00e8tement le probl\u00e8me traditionnel d'obstruction des tuyaux. Une dispersion in\u00e9gale ne permet pas de garantir la qualit\u00e9 des pi\u00e8ces moul\u00e9es et peut entra\u00eener d'autres probl\u00e8mes.<\/p>","protected":false},"excerpt":{"rendered":"
