L'un des probl\u00e8mes fondamentaux li\u00e9s \u00e0 la pr\u00e9paration du flux consiste \u00e0 exploiter ses propri\u00e9t\u00e9s physiques li\u00e9es \u00e0 son faible point de fusion et \u00e0 cr\u00e9er un environnement \u00e0 faible point de fusion pour le processus d'affinage gr\u00e2ce \u00e0 la conception de sa composition.<\/p>\n
Le principe de fonctionnement de la purification par flux de l'aluminium consiste \u00e0 atteindre l'objectif de purification en adsorbant et en dissolvant les inclusions d'oxyde pr\u00e9sentes dans le bain d'aluminium fondu ainsi que l'hydrog\u00e8ne adsorb\u00e9 sur celles-ci, puis en les faisant remonter \u00e0 la surface du bain d'aluminium fondu gr\u00e2ce \u00e0 la diff\u00e9rence de densit\u00e9. Le processus d'\u00e9limination des flux et de purification est un processus multiphasique complexe, soumis \u00e0 de nombreuses contraintes, dont les plus importantes sont les conditions thermodynamiques et cin\u00e9tiques de la purification.<\/p>","protected":false},"excerpt":{"rendered":"
