L'agent d'affinage pour fonderie d'aluminium est l'un des solvants les plus courants ; il se pr\u00e9sente principalement sous forme de poudre blanche ou de granul\u00e9s, et est obtenu \u00e0 partir d'un m\u00e9lange de divers sels inorganiques selon des proportions bien d\u00e9finies.<\/p>\n

Lors de la fusion de produits en aluminium, l'ajout d'une quantit\u00e9 appropri\u00e9e de agent de raffinage<\/a> Il permet d'\u00e9liminer efficacement l'hydrog\u00e8ne et les scories d'oxyde flottantes pr\u00e9sentes dans l'aluminium en fusion. Cela s'explique principalement par le fait que l'agent d'affinage se d\u00e9compose facilement \u00e0 haute temp\u00e9rature, notamment parce que le gaz produit est susceptible de subir des r\u00e9actions chimiques, et que la forte capacit\u00e9 d'adsorption des inclusions de scories permet \u00e0 l'hydrog\u00e8ne de s'\u00e9chapper de la masse fondue, ce qui lui conf\u00e8re un r\u00f4le significatif dans le processus de nettoyage des scories. Il s'agit d'un choix judicieux pour les entreprises ayant des exigences \u00e9lev\u00e9es en mati\u00e8re de fusion d'aluminium pur.<\/p>\n

L'utilisation de l'agent d'affinage pour fonderie d'aluminium est relativement simple. Il suffit de le saupoudrer \u00e0 la surface du bain d'aluminium en fusion, de l'enfoncer rapidement dans le bain, de bien le m\u00e9langer, puis de laisser reposer pour permettre l'\u00e9limination des scories.<\/p>\n

Lors de l'utilisation, vous pouvez recourir \u00e0 une machine \u00e0 jet ; l'effet sera meilleur si vous proc\u00e9dez \u00e0 une pulv\u00e9risation avec un gaz inerte. Le dosage est d'environ 0,31 TP3T par rapport au poids de l'aluminium fondu. Si la puret\u00e9 de l'aluminium fondu est relativement \u00e9lev\u00e9e, veuillez ajouter davantage d'agent d'affinage.<\/p>\n

\"Agent<\/p>\n

Il existe de nombreux types de m\u00e9taux en fusion d'alliages d'aluminium flux de raffinage<\/a> utilis\u00e9s dans la fusion des alliages d'aluminium, qui peuvent \u00eatre class\u00e9s en deux cat\u00e9gories : les agents de recouvrement (fux qui emp\u00eachent l'oxydation de la masse fondue et l'inhalation) et les agents d'affinage (\u00e9limination des gaz et des inclusions). Agents de rev\u00eatement<\/a> sont diff\u00e9rents des agents de raffinage.<\/p>\n

Tout flux utilis\u00e9 dans le processus de fusion des alliages d'aluminium doit r\u00e9pondre aux conditions suivantes.<\/p>\n

1. Le point de fusion doit \u00eatre inf\u00e9rieur \u00e0 la temp\u00e9rature de fusion de l'alliage d'aluminium.
\n2. La densit\u00e9 doit \u00eatre inf\u00e9rieure \u00e0 celle de l'alliage d'aluminium.
\n3. Il permet d'adsorber et de dissoudre les inclusions pr\u00e9sentes dans la masse fondue et d'\u00e9liminer les gaz qu'elle contient.
\n4. Il ne doit pas entrer en r\u00e9action chimique avec le m\u00e9tal ni avec le rev\u00eatement du four. S'il r\u00e9agit avec le m\u00e9tal, il ne doit produire qu'un gaz inerte insoluble dans le m\u00e9tal, et le fondant doit \u00eatre insoluble dans le m\u00e9tal en fusion.
\n5. Faible hygroscopicit\u00e9 et faible pression d'\u00e9vaporation.
\n6. Il ne doit pas contenir ni d\u00e9gager d'impuret\u00e9s ni de gaz nocifs.
\n7. Il doit pr\u00e9senter une viscosit\u00e9 et une fluidit\u00e9 ad\u00e9quates.
\n8, facile \u00e0 fabriquer : bon march\u00e9.<\/p>","protected":false},"excerpt":{"rendered":"
