<\/p>\nErimi\u015f metalden gazlar\u0131 ve safs\u0131zl\u0131klar\u0131 gidermenin bir yolu, gaz giderme i\u015flemidir. Bu fiziksel s\u00fcre\u00e7, eriyik i\u00e7ine ak\u0131 gaz\u0131n\u0131n enjekte edilmesini i\u00e7erir. Hidrojen, eriyik i\u00e7inde dif\u00fczyon yoluyla yay\u0131l\u0131p kabarc\u0131\u011fa girerek temizlenmi\u015f kabarc\u0131\u011f\u0131n i\u00e7ine ula\u015f\u0131r. Kabarc\u0131k i\u00e7inde hidrojen, kabarc\u0131\u011f\u0131n y\u00fczeyine yap\u0131\u015f\u0131r ve kabarc\u0131\u011f\u0131n i\u00e7ine adsorbe olur. Ard\u0131ndan hidrojen, kabarc\u0131klar arac\u0131l\u0131\u011f\u0131yla eriyikten d\u0131\u015far\u0131 \u00e7\u0131kar\u0131l\u0131r.<\/p>\n

Do\u011fal olarak, \u00f6zellikle erimi\u015f al\u00fcminyumda, nihai d\u00f6k\u00fcm \u00fcr\u00fcn\u00fcndeki bu t\u00fcr safs\u0131zl\u0131klar\u0131 ortadan kald\u0131rmak veya en aza indirmek i\u00e7in erimi\u015f metalin gaz giderme i\u015fleminin iyile\u015ftirilmesine b\u00fcy\u00fck bir ihtiya\u00e7 vard\u0131r; \u00f6zellikle de elde edilen metal, dekoratif \u015feritler gibi dekoratif \u00fcr\u00fcnlerde kullan\u0131ld\u0131\u011f\u0131nda veya u\u00e7ak d\u00f6vme par\u00e7alar\u0131, ekstr\u00fczyonlar ve hafif folyolar gibi \u00fcr\u00fcnlerin temel teknik \u00f6zelliklerini kar\u015f\u0131lad\u0131\u011f\u0131nda. S\u00f6z konusu safs\u0131zl\u0131klar, nihai d\u00f6k\u00fcm \u00fcr\u00fcn\u00fcn \u00e7ekme mukavemeti ve korozyon direnci gibi \u00f6zelliklerinin kayb\u0131na yol a\u00e7ar.<\/p>\n
S\u0131k\u0131 erimi\u015f metal gaz giderme i\u015flem s\u00fcre\u00e7leri (gaz ak\u0131s\u0131 veya eriyik filtrasyonu gibi), bu t\u00fcr kusurlar\u0131n g\u00f6r\u00fclme s\u0131kl\u0131\u011f\u0131n\u0131 en aza indirmi\u015ftir. Ancak, bu t\u00fcr i\u015flemler genel olarak bu kusurlar\u0131n g\u00f6r\u00fclme s\u0131kl\u0131\u011f\u0131n\u0131 tatmin edici bir d\u00fczeye indirgemekte ba\u015far\u0131l\u0131 olsalar da, etkisiz veya ekonomik olmayan y\u00f6ntemler olduklar\u0131 ortaya \u00e7\u0131km\u0131\u015ft\u0131r. Genel ocak eritme gibi geleneksel olarak uygulanan eritme i\u015flemi, belirli miktarda erimi\u015f metal i\u00e7eren bir bekletme f\u0131r\u0131n\u0131na eritme gaz\u0131n\u0131n verilmesini i\u00e7erir.<\/p>\n
Bu prosed\u00fcr, i\u015flenmekte olan metalin sabit kalmas\u0131 ve i\u015flenebilir durumda olmas\u0131 i\u00e7in, ak\u0131 gaz\u0131 sirk\u00fclasyonu s\u0131ras\u0131nda erimi\u015f metalin f\u0131r\u0131nda olduk\u00e7a uzun bir s\u00fcre tutulmas\u0131n\u0131 gerektirir. Bu ad\u0131m\u0131n bir\u00e7ok dezavantaj\u0131 vard\u0131r; bunlar\u0131n aras\u0131nda, ak\u0131 i\u015flemi s\u0131ras\u0131nda f\u0131r\u0131n\u0131n uzun s\u00fcre at\u0131l kalmas\u0131 nedeniyle verimlilik azal\u0131r ve maliyet artar. Daha da \u00f6nemlisi, ak\u0131\u015fkan\u0131n erimi\u015f metali yeterince kaplayamamas\u0131 nedeniyle, ak\u0131\u015fkan\u0131n i\u015fleme verimlili\u011finin yetersiz kalmas\u0131, kabarc\u0131klar\u0131n b\u00fcy\u00fck olmas\u0131 ve eriyik i\u00e7inde kabarc\u0131klar\u0131n zay\u0131f da\u011f\u0131lmas\u0131 sonucu gaz olu\u015fumuna yol a\u00e7ar. Di\u011fer fakt\u00f6rler aras\u0131nda, d\u00f6k\u00fcmden \u00f6nce safs\u0131zl\u0131klar\u0131n eriyik i\u00e7ine yeniden girmesine izin vermek i\u00e7in f\u0131r\u0131n\u0131n konumunun k\u0131s\u0131tlanmas\u0131 ve gerekli olan b\u00fcy\u00fck miktardaki ak\u0131 ile bunun sirk\u00fclasyon konumu nedeniyle ortaya \u00e7\u0131kan y\u00fcksek emisyonlar say\u0131labilir.<\/p>\n
