Le degr\u00e9 de purification de la masse fondue d\u00e9pend des conditions de contact, c'est-\u00e0-dire de la surface de contact entre la masse fondue et l'adsorbant, de la dur\u00e9e et de l'\u00e9tat de surface. L\u2019affinage par adsorption comprend l\u2019affinage par gaz, l\u2019affinage par sels de chlorure, l\u2019affinage par fondant et la filtration de la masse fondue. L\u2019affinage par adsorption est actuellement la m\u00e9thode d\u2019affinage la plus r\u00e9pandue dans l\u2019industrie de l\u2019aluminium.<\/p>\n![\"Filtres](\"http:\/\/alalloycasting.com\/wp-content\/uploads\/2021\/10\/Aluminum-Casting-Ceramic-Filters.jpg\")

L'affinage sans adsorption consiste \u00e0 modifier l'\u00e9tat d'\u00e9quilibre du syst\u00e8me m\u00e9tal-inclusions sans recourir \u00e0 des adsorbants, de mani\u00e8re \u00e0 \u00e9liminer les inclusions gazeuses et solides non m\u00e9talliques de la masse d'aluminium en fusion. L'affinage sans adsorption a un effet d'affinage sur toutes les masses d'aluminium fondu. Cet effet d\u00e9pend des conditions externes qui rompent l'\u00e9quilibre, ainsi que des caract\u00e9ristiques de mouvement de la masse d'aluminium fondu, des inclusions et des gaz. L'affinage sans adsorption comprend notamment le traitement statique, le traitement sous vide, le traitement par ultrasons et le traitement de pr\u00e9-solidification.<\/p>\n
Depuis des d\u00e9cennies, les technologies de raffinage et de purification de l'aluminium fondu \u00e9voluent vers plus de respect de l'environnement, un rendement \u00e9lev\u00e9, une faible consommation et une plus grande facilit\u00e9 d'utilisation. En combinant ces m\u00e9thodes avec une meilleure efficacit\u00e9 de traitement, le traitement composite hors four est devenu une nouvelle tendance. Notre syst\u00e8me de d\u00e9gazage en ligne et notre syst\u00e8me de filtration sont largement utilis\u00e9s dans les fonderies d\u2019aluminium. Ils permettent de traiter un volume important d\u2019aluminium fondu en une seule fois.<\/p>","protected":false},"excerpt":{"rendered":"
