flux de recouvrement<\/a> peuvent recouvrir la surface de l'aluminium et des alliages d'aluminium \u00e0 l'\u00e9tat fondu. Les sels de chlorure et de fluor couramment utilis\u00e9s ont un point de fusion sup\u00e9rieur \u00e0 celui de l'aluminium et des alliages d'aluminium. C'est pourquoi on choisit comme fondant un sel mixte pouvant se pr\u00e9senter \u00e0 l'\u00e9tat eutectique ou \u00e0 l'\u00e9tat de solution solide. Le chlorure de sodium et le chlorure de potassium peuvent former un sel eutectique fusible.<\/p>\n![\"Flux](\"http:\/\/alalloycasting.com\/wp-content\/uploads\/2021\/07\/Fluxes-for-Aluminum-Smelter-1.jpg\")
<\/p>\n
Le point de fusion de la composition eutectique compos\u00e9e de 55% de KCl et de 45% de NaCl est de 650 \u00b0C, ce qui permet de maintenir un niveau de liquide pr\u00e9sentant une bonne fluidit\u00e9 \u00e0 la temp\u00e9rature de fusion de l'alliage d'aluminium. La densit\u00e9 du sel mixte \u00e0 l\u2019\u00e9tat liquide est de 1,5 g\/cm\u00b3, ce qui est inf\u00e9rieur \u00e0 la densit\u00e9 de l\u2019aluminium fondu (2,4\u20132,5 g\/cm\u00b3) ; il peut donc mieux recouvrir la surface des bains d\u2019aluminium et d\u2019alliages d\u2019aluminium fondus. Ce sel binaire pr\u00e9sente une bonne stabilit\u00e9 chimique, ne r\u00e9agit pas chimiquement avec l\u2019aluminium fondu et poss\u00e8de une certaine capacit\u00e9 \u00e0 dissoudre les inclusions d\u2019oxyde d\u2019aluminium et l\u2019hydrog\u00e8ne pr\u00e9sents dans les bains d\u2019aluminium et d\u2019alliages d\u2019aluminium fondus. C\u2019est pourquoi le sel mixte eutectique de chlorure de sodium et de chlorure de potassium est souvent utilis\u00e9 comme composant de base des fondants pour l\u2019aluminium et les alliages d\u2019aluminium.<\/p>\n
Afin d\u2019am\u00e9liorer les propri\u00e9t\u00e9s du flux, il est n\u00e9cessaire d\u2019y ajouter des composants suppl\u00e9mentaires. \u00c0 partir du sel chlorure eutectique, on peut ajouter une quantit\u00e9 appropri\u00e9e de sel fluor\u00e9, tel que le fluorure de sodium, le fluorure de calcium, la cryolite, etc., pour renforcer la capacit\u00e9 du flux \u00e0 dissoudre les oxydes, en particulier l\u2019alumine. L'ajout de sel fluor\u00e9 permet \u00e9galement d'augmenter la mouillabilit\u00e9 du flux vis-\u00e0-vis de l'alumine, am\u00e9liorant ainsi sa capacit\u00e9 d'adsorption, tout en augmentant la tension superficielle du flux, ce qui facilite sa s\u00e9paration des masses fondues d'aluminium et d'alliages d'aluminium et r\u00e9duit le risque de m\u00e9lange avec celles-ci.<\/p>","protected":false},"excerpt":{"rendered":"
