Al\u00fcminyum eritme i\u015fleminin \u00f6nemli bir par\u00e7as\u0131 olarak, \u00e7evrimi\u00e7i gaz giderme, al\u00fcminyum d\u00f6k\u00fcmhaneleri taraf\u0131ndan giderek daha fazla ilgi g\u00f6rmektedir. Gaz giderme ve filtreleme, al\u00fcminyum eritme i\u015fleminin \u00f6nemli a\u015famalar\u0131d\u0131r. \u00c7evrimi\u00e7i gaz giderme i\u015flemi, hem f\u0131r\u0131n\u0131n \u00f6n a\u015famas\u0131nda ger\u00e7ekle\u015ftirilen al\u00fcminyum eriyik ar\u0131tmas\u0131ndan hem de \u00e7evrimi\u00e7i ar\u0131tman\u0131n son a\u015famas\u0131ndaki filtreleme i\u015fleminden fayda sa\u011flamaktad\u0131r. Bu ar\u0131tma i\u015flemleri birbirini tamamlar ve genel etkileri, tek bir ar\u0131tma i\u015fleminin etkisinden \u00e7ok daha iyidir.<\/p>\n
