Pour l'aluminium et les alliages d'aluminium, le d\u00e9gazage et la formation de scories \u00e0 l'aide d'un fondant constituent une m\u00e9thode importante. Lors du raffinage par fondant, un grand nombre de gouttelettes de fondant fines et dispers\u00e9es se forment dans la masse fondue. Conform\u00e9ment \u00e0 la loi de l'\u00e9quilibre de dissolution, l'hydrog\u00e8ne atomique pr\u00e9sent dans la masse fondue est achemin\u00e9 vers la surface du liquide sous l'effet de la diffusion des gouttelettes de flux, ce qui permet de r\u00e9duire la teneur en hydrog\u00e8ne de la masse fondue.<\/p>\n

Lors de la coul\u00e9e, le m\u00e9tal en fusion contient une grande quantit\u00e9 de gaz et se solidifie, formant un trou rond \u00e0 la surface interne lisse dans le lingot. Les principales causes de la formation de pores sont les suivantes : les mati\u00e8res premi\u00e8res utilis\u00e9es sont humides, et le four ainsi que les outils ne sont pas compl\u00e8tement secs. La temp\u00e9rature de fusion est \u00e9lev\u00e9e, la couverture est insuffisante, le temps de s\u00e9jour \u00e0 haute temp\u00e9rature est long et la masse fondue absorbe une grande quantit\u00e9 de gaz. Si l'affinage par d\u00e9gazage n'est pas complet, lors du processus de cristallisation, le gaz ne parvient pas \u00e0 s'\u00e9chapper de la masse fondue et forme des pores. Apr\u00e8s le traitement sous pression, les pores peuvent \u00eatre comprim\u00e9s, mais ce processus n\u2019est pas ais\u00e9 et peut facilement entra\u00eener des d\u00e9fauts tels que la formation d\u2019une peau ou de bulles dans les produits trait\u00e9s et thermotrait\u00e9s, ce qui r\u00e9duit consid\u00e9rablement les diff\u00e9rentes propri\u00e9t\u00e9s du m\u00e9tal.<\/p>\n

Le flux utilis\u00e9 pour la purification est un sel pr\u00e9sentant un faible point de fusion, une faible densit\u00e9, une faible tension superficielle, une activit\u00e9 \u00e9lev\u00e9e et une forte capacit\u00e9 d'adsorption des oxydes. Pour l'utiliser, placez un petit morceau de flux dans la cage en fer, puis ins\u00e9rez-la au fond du four de m\u00e9lange et remuez-la d'avant en arri\u00e8re. Une fois le flux \u00e9puis\u00e9, retirez la cage en fer et laissez reposer pendant 5 \u00e0 10 minutes. Retirez l'\u00e9cume de surface, puis proc\u00e9dez \u00e0 la coul\u00e9e.<\/p>\n

\"Aluminium<\/p>\n

Si n\u00e9cessaire, le flux de recouvrement<\/a> Il peut \u00e9galement \u00eatre saupoudr\u00e9 \u00e0 la surface pour la recouvrir. Bien que le fondant puisse dissoudre l'hydrog\u00e8ne et g\u00e9n\u00e9rer des gaz volatils au contact de l'aluminium, il poss\u00e8de un effet de d\u00e9gazage. Cependant, la pratique a d\u00e9montr\u00e9 que cet effet de d\u00e9gazage est moins efficace que celui obtenu par l'affinage au gaz et le d\u00e9gazage, tandis que son efficacit\u00e9 pour \u00e9liminer les scories de la masse fondue est bien sup\u00e9rieure \u00e0 celle de l'affinage au gaz. L'effet d'\u00e9limination des scories du fondant s'explique principalement par l'adsorption, la dissolution et la r\u00e9action chimique du fondant avec les scories d'alumine pr\u00e9sentes dans la masse fondue.<\/p>","protected":false},"excerpt":{"rendered":"
