La purification du m\u00e9tal en fusion rev\u00eat une grande importance pour la fonderie. La qualit\u00e9 des pi\u00e8ces moul\u00e9es et des m\u00e9taux lamin\u00e9s peut \u00eatre encore am\u00e9lior\u00e9e gr\u00e2ce \u00e0 l'adoption de m\u00e9thodes de purification de la masse fondue, d'\u00e9quipements adapt\u00e9s et de mesures de gestion appropri\u00e9es. La purification du m\u00e9tal en fusion peut \u00eatre r\u00e9alis\u00e9e selon les modalit\u00e9s et m\u00e9thodes suivantes.<\/p>\n

Purification du m\u00e9tal en fusion<\/h2>\n

Mode de transfert de la masse fondue : le mode de transfert de la masse fondue du four vers le four statique a \u00e9t\u00e9 am\u00e9lior\u00e9, et le mode par gouttes a \u00e9t\u00e9 remplac\u00e9 par un syst\u00e8me \u00e0 plan inclin\u00e9, afin d\u2019\u00e9viter l\u2019augmentation de l\u2019oxydation et l\u2019aggravation de l\u2019aspiration des gaz caus\u00e9es par l\u2019\u00e9gouttement. Parall\u00e8lement, il convient d\u2019\u00e9viter d\u2019exposer de grandes surfaces de mati\u00e8re fondue \u00e0 l\u2019air, ce qui augmenterait l\u2019oxydation et l\u2019absorption de gaz. Am\u00e9liorez l\u2019isolation thermique de la goulotte, utilisez de nouveaux mat\u00e9riaux, augmentez l\u2019\u00e9paisseur de la goulotte ou recouvrez-la. D\u00e9terminez une temp\u00e9rature de fusion appropri\u00e9e afin d\u2019\u00e9viter toute combustion dans la goulotte due \u00e0 une temp\u00e9rature de fusion trop basse, ce qui augmenterait l\u2019oxydation et l\u2019absorption de gaz par la mati\u00e8re fondue.<\/p>\n

Affinage en four statique : en am\u00e9liorant le tube d'affinage ou en contr\u00f4lant le d\u00e9bit et la pression du fluide de d\u00e9gazage, il est possible d'\u00e9viter l'influence des bulles excessives sur l'efficacit\u00e9 du d\u00e9gazage. Afin de produire une feuille d'aluminium de haute qualit\u00e9, les m\u00e9thodes suivantes sont propos\u00e9es pour remplacer l'affinage actuel, qui repose uniquement sur un gaz inerte, et ainsi am\u00e9liorer l'efficacit\u00e9 de la purification de la masse fondue.<\/p>\n

\"Purification<\/p>\n

Affinage par m\u00e9lange de flux gazeux : injection d'une petite quantit\u00e9 de poudre de flux, formant un film de sel liquide \u00e0 la surface de la bulle. Le film d'oxyde \u00e0 la surface de la bulle se brise, est adsorb\u00e9 puis se dissout. L'hydrog\u00e8ne pr\u00e9sent dans la masse fondue se diffuse dans la bulle, ce qui am\u00e9liore l'effet de d\u00e9gazage.<\/p>\n

CCl\u2084 : Le CCl\u2084 r\u00e9agit avec l'aluminium pour former de l'AlCl\u2083, du HCl, du Cl\u2082 et d'autres gaz actifs. L'hydrog\u00e8ne pr\u00e9sent dans la masse fondue est \u00e9limin\u00e9 par des processus physiques et chimiques, ce qui am\u00e9liore l'efficacit\u00e9 du raffinage.<\/p>\n

Le m\u00e9lange de fluides frigorig\u00e8nes fluor\u00e9s et d'argon est utilis\u00e9 pour l'affinage : le chlore et le fluor (CCL\u2082F\u2082) issus de la d\u00e9composition du fr\u00e9on peuvent r\u00e9agir avec les \u00e9l\u00e9ments des alliages d'aluminium pour former des sels fondus tels que l'HCl, l'AlCl\u2083 et l'AlF\u2083, qui jouent le r\u00f4le de flux \u00e0 bulles dans le processus d'affinage mixte.<\/p>\n

Le dispositif de d\u00e9gazage en ligne<\/a> introduit un gaz protecteur dans la chambre afin de r\u00e9duire l'absorption et l'oxydation de l'hydrog\u00e8ne. En optimisant la vitesse de rotation et en am\u00e9liorant la sortie d'air du rotor, les bulles sont plus fines et l'efficacit\u00e9 du d\u00e9gazage est am\u00e9lior\u00e9e.<\/p>\n

Afin de produire du coton d'aluminium de haute qualit\u00e9, un filtre \u00e0 mailles larges (tel qu'un filtre de 10 \u00e0 20 ppig) est ajout\u00e9 avant le d\u00e9gazage afin d'am\u00e9liorer la puret\u00e9 de la masse fondue, d'augmenter le taux de diffusion de l'hydrog\u00e8ne dans celle-ci et d'optimiser l'efficacit\u00e9 du d\u00e9gazage en ligne. Renforcer le nettoyage et le remplacement des Bo\u00eetier de filtre CFF<\/a> afin de garantir la forme et les dimensions de la chambre de filtration et d'assurer l'efficacit\u00e9 du filtrage.<\/p>","protected":false},"excerpt":{"rendered":"
