L'unit\u00e9 de d\u00e9gazage \u00e0 l'azote de type rotatif permet une \u00e9limination plus compl\u00e8te de l'hydrog\u00e8ne que le d\u00e9gazage en continu. De plus, le d\u00e9gazeur rotatif n'utilise pas de sels nocifs contenant du chlore et du fluor.<\/p>\n

L'unit\u00e9 de d\u00e9gazage \u00e0 l'azote de type rotatif peut \u00e9galement combiner les fonctions de d\u00e9gazage et d'injection en flux continu. Dans ce cas, le gaz inerte sert de support au flux de granul\u00e9s. Cette m\u00e9thode est appel\u00e9e \u00ab injection en flux continu \u00bb.<\/p>\n

Avantages de l'unit\u00e9 de d\u00e9gazage \u00e0 l'azote de type rotatif<\/strong><\/p>\n

Haute efficacit\u00e9 de l'action du flux gr\u00e2ce \u00e0 un meilleur m\u00e9lange avec la masse fondue ;
\nTemps de traitement court ;
\nIntroduction du d\u00e9bit r\u00e9glable ;
\nUne m\u00e9thode de d\u00e9capage plus respectueuse de l'environnement.<\/p>\n

Dans le m\u00e9thode de d\u00e9gazage rotatif<\/a>, de l'azote, gaz inerte ou chimiquement inactif, est inject\u00e9 \u00e0 travers un arbre rotatif et un rotor.<\/p>\n

L'\u00e9nergie g\u00e9n\u00e9r\u00e9e par la rotation de l'arbre entra\u00eene la formation d'un grand nombre de fines bulles pr\u00e9sentant un rapport surface\/volume tr\u00e8s \u00e9lev\u00e9. Cette grande surface sp\u00e9cifique favorise une diffusion rapide et efficace de l'hydrog\u00e8ne dans les bulles de gaz, ce qui contribue \u00e0 \u00e9quilibrer l'activit\u00e9 de l'hydrog\u00e8ne dans les phases liquide et gazeuse.<\/p>\n

Pour le d\u00e9gazage et la filtration de l'aluminium fondu et de ses alliages. Permet de r\u00e9duire la formation de bulles et les impuret\u00e9s dans l'aluminium liquide.<\/p>\n

L'unit\u00e9 de d\u00e9gazage en ligne destin\u00e9e \u00e0 l'aluminium de haute puret\u00e9 est con\u00e7ue selon le principe d'un four ; elle utilise une chambre de traitement pour le d\u00e9gazage, compos\u00e9e d'un r\u00e9servoir de d\u00e9gazage et d'une chambre statique.<\/p>\n

Proc\u00e9der au traitement en interne \u00e0 l'aide d'un rotor de d\u00e9gazage ; lorsque la convection s'installe dans l'enceinte, veiller \u00e0 ce que les petites bulles pr\u00e9sentes dans l'aluminium liquide puissent se propager pleinement.<\/p>\n

La surface de contact augmente le volume de la bulle et celui de l'aluminium liquide.<\/p>\n

Protection contre les variations de niveau du liquide en aluminium, compensation de temp\u00e9rature.<\/p>\n

L'armoire de l'unit\u00e9 de d\u00e9gazage en ligne a \u00e9t\u00e9 con\u00e7ue de mani\u00e8re herm\u00e9tique, ce qui emp\u00eache toute prise d'air ext\u00e9rieur et \u00e9vite ainsi toute pollution secondaire.<\/p>\n

L'efficacit\u00e9 du d\u00e9gazage des \u00e9quipements a \u00e9t\u00e9 consid\u00e9rablement am\u00e9lior\u00e9e.<\/p>\n

L'unit\u00e9 de d\u00e9gazage est \u00e9quip\u00e9e d'un poste de travail ; le proc\u00e9d\u00e9 utilisant de l'aluminium liquide permet de maintenir la temp\u00e9rature gr\u00e2ce \u00e0 un chauffage \u00e9lectrique. Le syst\u00e8me de chauffage, qui utilise un thermoplongeur, offre un rendement \u00e9lev\u00e9. Il est \u00e9quip\u00e9 d'\u00e9l\u00e9ments chauffants en carbure de silicium et d'un r\u00e9gulateur de temp\u00e9rature \u00e0 thyristor, ce qui garantit une grande pr\u00e9cision de r\u00e9gulation et une grande facilit\u00e9 d'utilisation.<\/p>","protected":false},"excerpt":{"rendered":"
