\u00c0 l'heure actuelle, la m\u00e9thode de d\u00e9gazage par rotation est la plus r\u00e9pandue.<\/p>\n

Au cours du processus de fusion et de coul\u00e9e d'un alliage d'aluminium recycl\u00e9, le m\u00e9tal en fusion entre en contact avec les gaz du four et l'atmosph\u00e8re, ce qui provoque une s\u00e9rie de r\u00e9actions physiques et chimiques g\u00e9n\u00e9rant des gaz et des oxydes. Les gaz et les inclusions pr\u00e9sents dans le lingot d\u2019alliage provoquent l\u2019apparition de cloquages, de d\u00e9laminations et de d\u00e9chirures lors du traitement et de la d\u00e9formation, et r\u00e9duisent la r\u00e9sistance et la plasticit\u00e9 du m\u00e9tal ou de l\u2019alliage. Les gaz absorb\u00e9s provoquent la formation de bulles dans la t\u00f4le, ce qui entra\u00eene ce que l\u2019on appelle la \u201c fragilisation par l\u2019hydrog\u00e8ne \u201d, causant la rupture du mat\u00e9riau. C\u2019est pourquoi il est indispensable de proc\u00e9der \u00e0 un d\u00e9gazage avant la coul\u00e9e des lingots d\u2019aluminium.<\/p>\n

Dans le proc\u00e9d\u00e9 de d\u00e9gazage par rotation, un gaz inerte ou un gaz actif est introduit dans la masse fondue par l'interm\u00e9diaire d'un rotor de forme sp\u00e9cifique. La rotation \u00e0 grande vitesse du rotor permet de briser les bulles. Au cours du processus de remont\u00e9e des bulles, l'hydrog\u00e8ne et les inclusions solides sont \u00e9vacu\u00e9s de la surface de la masse fondue gr\u00e2ce au principe de la diff\u00e9rence de pression partielle et au principe d'adsorption, ce qui permet d'obtenir un effet de purification.<\/p>\n

\"\"<\/p>\n

La vitesse du rotor a une influence importante sur la zone de r\u00e9partition des bulles. Lorsque la vitesse est inf\u00e9rieure \u00e0 280 tr\/min, les bulles sont plus grosses. \u00c0 mesure que la vitesse augmente, la zone concern\u00e9e s'\u00e9tend davantage. Lorsque la vitesse de rotation est port\u00e9e \u00e0 410 tr\/min, la zone de r\u00e9partition des bulles change consid\u00e9rablement, et celles-ci se r\u00e9partissent sur toute la surface. La taille des bulles a une influence importante sur l'effet de d\u00e9gazage. Plus les bulles sont petites, plus la surface de contact totale avec la masse fondue est importante. D\u00e9gazage des m\u00e9taux<\/a> est principalement due \u00e0 la diffusion de l'hydrog\u00e8ne pr\u00e9sent dans la masse fondue vers les bulles. L'augmentation de la surface de contact entre les bulles et la masse fondue accro\u00eet la vitesse de d\u00e9gazage. De plus, la taille des bulles influe \u00e9galement sur leur temps de s\u00e9jour dans la masse fondue.<\/p>","protected":false},"excerpt":{"rendered":"
