Le processus de recyclage des d\u00e9chets d'aluminium comprend g\u00e9n\u00e9ralement les quatre \u00e9tapes fondamentales suivantes :<\/p>\n

Pr\u00e9paration des d\u00e9chets d'aluminium<\/strong>
\nTout d'abord, le tri primaire des d\u00e9chets d'aluminium, tels que l'aluminium pur, les alliages d'aluminium corroy\u00e9s, les alliages d'aluminium moul\u00e9s, les mat\u00e9riaux mixtes, etc. Les d\u00e9chets d\u2019aluminium doivent \u00eatre d\u00e9mont\u00e9s afin d\u2019en retirer l\u2019acier et les autres pi\u00e8ces en m\u00e9taux non ferreux li\u00e9es \u00e0 l\u2019aluminium, puis soumis \u00e0 des processus de lavage, de concassage, de s\u00e9paration magn\u00e9tique, de s\u00e9chage et autres pour obtenir de l\u2019aluminium de r\u00e9cup\u00e9ration.<\/p>\n

\"Processus<\/p>\n

Ingr\u00e9dients<\/strong>
\nEn fonction de la pr\u00e9paration et de la qualit\u00e9 des d\u00e9chets d'aluminium, et conform\u00e9ment aux exigences techniques des produits recycl\u00e9s, s\u00e9lectionner les mat\u00e9riaux adapt\u00e9s et calculer les quantit\u00e9s des diff\u00e9rents mat\u00e9riaux.<\/p>\n

Alliage d'aluminium d\u00e9form\u00e9 recycl\u00e9<\/strong>
\nAfin de garantir que la composition chimique de l'alliage r\u00e9ponde aux exigences techniques et aux exigences du proc\u00e9d\u00e9 de traitement sous pression, il convient d'ajouter, si n\u00e9cessaire, une partie de lingots d'aluminium primaire.<\/p>\n

Alliage d'aluminium moul\u00e9 recycl\u00e9<\/strong>
\nLes principaux \u00e9quipements utilis\u00e9s pour la production d'aluminium secondaire sont le four de fusion et le four d'affinage et de purification. Ces derni\u00e8res ann\u00e9es, AdTech a am\u00e9lior\u00e9 le processus de traitement et produit des agents d'affinage granulaires sans sodium afin de r\u00e9soudre les probl\u00e8mes de pollution environnementale, notamment en utilisant du N\u2082, de l'Ar, etc. comme agents d'affinage. AdTech a \u00e9galement mis au point un syst\u00e8me en ligne \u00e9quipement de purification par d\u00e9gazage<\/a> afin d'am\u00e9liorer le d\u00e9gazage et d'\u00e9liminer les impuret\u00e9s, ce qui permet de valoriser les d\u00e9chets d'aluminium de qualit\u00e9 inf\u00e9rieure et de les utiliser pour fabriquer des lingots d'aluminium secondaire destin\u00e9s \u00e0 la fonderie, au moulage sous pression, au laminage et aux alliages-ma\u00eetres.<\/p>\n

Dans le processus de recyclage des d\u00e9chets d'aluminium, la fusion de l'aluminium recycl\u00e9 et le traitement du bain de fusion constituent les \u00e9tapes cl\u00e9s pour garantir la qualit\u00e9 m\u00e9tallurgique de l'aluminium recycl\u00e9. La modification, l'affinage et la purification de la masse fondue d'aluminium permettent non seulement de modifier la forme du silicium pr\u00e9sent dans l'alliage aluminium-silicium et de purifier la masse fondue, mais aussi d'am\u00e9liorer consid\u00e9rablement les performances de l'alliage d'aluminium. L'affinage, la transformation et la purification de la masse d'aluminium fondu sont actuellement principalement r\u00e9alis\u00e9s \u00e0 l'aide de sels de chlorure et de fluorure tels que le NaCl, le NaF, le KCl et le Na\u2083AlF\u2086, et certains sont trait\u00e9s avec du C\u2081\u2082 ou du C\u2082C\u2081\u2086. Bien que l\u2019affinage de l\u2019aluminium fondu de r\u00e9cup\u00e9ration \u00e0 l\u2019aide de substances chlor\u00e9es donne de meilleurs r\u00e9sultats, ses sous-produits, tels que l\u2019AlCl\u2083, le HCl et le Cl, causent de graves dommages au corps humain, \u00e0 l\u2019environnement et aux \u00e9quipements.<\/p>","protected":false},"excerpt":{"rendered":"
