Ces derni\u00e8res ann\u00e9es, la transformation de l'aluminium impose des exigences de plus en plus \u00e9lev\u00e9es en mati\u00e8re de performances aux produits ou semi-finis en aluminium. La qualit\u00e9 de la masse fondue d\u2019aluminium est un facteur cl\u00e9 dans la production de produits semi-finis ou finis. AdTech a d\u00e9velopp\u00e9 diff\u00e9rents \u00e9quipements utilisant diverses techniques de purification de la masse fondue d\u2019alliages d\u2019aluminium afin d\u2019\u00e9liminer les gaz et les inclusions. Les exigences globales en mati\u00e8re de performances des masses fondues d\u2019aluminium visent \u00e0 optimiser l\u2019\u00e9limination de l\u2019hydrog\u00e8ne, des inclusions et des m\u00e9taux alcalins pr\u00e9sents dans la masse fondue.<\/p>\n

En ce qui concerne le traitement de la masse fondue, \u00e9tant donn\u00e9 que cela d\u00e9pend du type d\u2019alliage coul\u00e9, du type d\u2019installation de production (usine de refusion, fonderie, etc.) ou du type de produit fabriqu\u00e9 et coul\u00e9 (brames, lingots, barres d\u2019extrusion, pi\u00e8ces moul\u00e9es, etc.), En ce qui concerne la teneur en m\u00e9taux alcalins et la d\u00e9shydrog\u00e9nation, en fonction des diff\u00e9rentes exigences des entreprises de transformation de l'aluminium en mati\u00e8re de purification de la masse fondue, utilisez :<\/p>\n

Agent de raffinage granulaire<\/a><\/strong>: Dans le four de fusion et le four de maintien, on utilise un agent d'affinage granulaire et de l'azote comme gaz vecteur pour \u00e9liminer les m\u00e9taux alcalins et les impuret\u00e9s pr\u00e9sents dans l'aluminium fondu \u00e0 l'int\u00e9rieur du four.<\/p>\n

\"Flux<\/p>\n

Syst\u00e8me de d\u00e9gazage en ligne<\/a><\/strong>: Le traitement de la masse fondue est effectu\u00e9 dans la cuve de d\u00e9gazage afin d'\u00e9liminer l'hydrog\u00e8ne et les impuret\u00e9s. Le contr\u00f4le de la teneur en m\u00e9taux alcalins et en hydrog\u00e8ne dans la masse fondue d'alliage d'aluminium permet de r\u00e9pondre aux besoins des utilisateurs en mati\u00e8re d'am\u00e9lioration de la qualit\u00e9 des lingots.<\/p>\n

\u00c9quipements de filtration en ligne<\/a><\/strong>: Installez des plaques filtrantes en mousse c\u00e9ramique dans le caisson de filtration afin de filtrer davantage l'aluminium fondu et d'\u00e9liminer les particules fines d'impuret\u00e9s.<\/p>\n

La puret\u00e9 de l'aluminium fondu, c'est-\u00e0-dire la r\u00e9duction des inclusions dans celui-ci, est un facteur essentiel dans la fabrication de produits de haute qualit\u00e9. Les inclusions pr\u00e9sentes dans l'alliage d'aluminium rendent la structure de l'alliage discontinue, r\u00e9duisent la densit\u00e9 du produit, provoquent de la corrosion et des fissures, et diminuent les propri\u00e9t\u00e9s m\u00e9caniques du produit final.<\/p>\n

Avec le d\u00e9veloppement progressif des applications industrielles de l'aluminium, les produits sont soumis \u00e0 des exigences techniques de plus en plus \u00e9lev\u00e9es en mati\u00e8re de traitement de la masse fondue, et les \u00e9quipements de purification de la masse fondue d'aluminium doivent se conformer \u00e0 la politique de protection de l'environnement visant \u00e0 produire de l'aluminium \u00ab vert \u00bb. Ce n\u2019est qu\u2019en am\u00e9liorant continuellement les \u00e9quipements et les technologies de purification de la fonte d\u2019aluminium que nous pourrons r\u00e9pondre aux normes de qualit\u00e9 toujours plus \u00e9lev\u00e9es des utilisateurs et maintenir une comp\u00e9titivit\u00e9 durable dans la production de mat\u00e9riaux hautement performants et de grande qualit\u00e9. AdTech s'engage \u00e0 am\u00e9liorer en permanence les technologies de traitement et de contr\u00f4le de la masse fondue, \u00e0 fournir une gamme compl\u00e8te d'\u00e9quipements de purification de la masse fondue et \u00e0 adopter des technologies vertes afin de parvenir \u00e0 un d\u00e9veloppement durable alliant protection de l'environnement et efficacit\u00e9 dans l'industrie de la transformation de l'aluminium.<\/p>","protected":false},"excerpt":{"rendered":"
