agent de d\u00e9gazage<\/a> se d\u00e9composent facilement \u00e0 haute temp\u00e9rature ; le gaz ainsi produit r\u00e9agit facilement avec l'hydrog\u00e8ne, pr\u00e9sente une forte capacit\u00e9 d'adsorption sur les scories et s'\u00e9chappe rapidement de la masse fondue. Les autres composants ont un effet de s\u00e9paration des scories.<\/p>\nLes flux de d\u00e9gazage de l'aluminium sont adapt\u00e9s aux alliages d'aluminium couramment utilis\u00e9s (alliages \u00e0 haute teneur en magn\u00e9sium et alliages d'aluminium-magn\u00e9sium) ainsi qu'\u00e0 la fusion de l'aluminium pur, \u00e0 l'affinage par d\u00e9gazage et \u00e0 l'\u00e9limination des scories.<\/p>\n
L'agent d'affinage est saupoudr\u00e9 \u00e0 la surface du bain d'aluminium en fusion et est rapidement incorpor\u00e9 dans celui-ci. Une fois le m\u00e9lange homog\u00e8ne obtenu, on laisse reposer le bain pour permettre la formation des scories ; s'il est pulv\u00e9ris\u00e9, l'agent d'affinage est projet\u00e9 dans le bain d'aluminium en fusion \u00e0 l'aide d'un gaz inerte.<\/p>\n
Fonction de flux pour la fusion de l'aluminium<\/strong><\/p>\n1. Modifier la mouillabilit\u00e9 de l'aluminium fondu par rapport \u00e0 l'oxyde (alumine), de mani\u00e8re \u00e0 ce que l'aluminium fondu se s\u00e9pare facilement de l'oxyde (alumine), afin que la majeure partie de l'oxyde (alumine) soit entra\u00een\u00e9e par le flux et r\u00e9duise ainsi la teneur en oxydes dans la pi\u00e8ce.<\/p>\n
2. Le flux peut modifier l'\u00e9tat du film d'oxyde \u00e0 la surface du bain fondu. En effet, il est capable de fragmenter le film d'oxyde solide et dense qui recouvre la surface du bain fondu en fines particules, ce qui permet \u00e0 l'hydrog\u00e8ne pr\u00e9sent dans le bain fondu de s'\u00e9chapper plus facilement de l'espace entre les particules de la couche de film d'oxyde et de se disperser dans l'atmosph\u00e8re.<\/p>\n
3. La pr\u00e9sence de la couche de flux permet d'isoler le contact entre la vapeur d'eau et l'aluminium en fusion dans l'atmosph\u00e8re, ce qui rend difficile la p\u00e9n\u00e9tration de l'hydrog\u00e8ne dans l'aluminium en fusion tout en emp\u00eachant la perte par oxydation de la fonte.<\/p>\n
4. Le flux adsorbe les oxydes pr\u00e9sents lors de la fusion de l'aluminium afin de purifier le bain de fusion. En r\u00e9sum\u00e9, l'effet de l'affinage en flux visant \u00e0 \u00e9liminer les inclusions repose principalement sur l'adsorption, la dissolution et les r\u00e9actions chimiques avec les films d'oxydes et les inclusions non m\u00e9talliques pr\u00e9sents dans le bain de fusion.<\/p>","protected":false},"excerpt":{"rendered":"
