Erimi\u015f al\u00fcminyumda genellikle nihai d\u00f6k\u00fcm metal \u00fcr\u00fcn\u00fcne zarar veren s\u00fcr\u00fcklenen kat\u0131 maddeler bulunur. Bu s\u00fcr\u00fcklenen kat\u0131 maddeler genellikle \u00fc\u00e7 kaynaktan gelir. Bunlardan baz\u0131lar\u0131 al\u00fcmina par\u00e7ac\u0131klar\u0131d\u0131r; y\u00fczeydeki y\u00fczen oksit tabakas\u0131 bunlar\u0131 s\u0131v\u0131 ak\u0131\u015f\u0131na \u00e7eker; s\u00fcr\u00fcklenen par\u00e7ac\u0131klar\u0131n bir k\u0131sm\u0131 ise f\u0131r\u0131n astar\u0131, ta\u015f\u0131ma olu\u011fu ve erimi\u015f al\u00fcminyum i\u015fleme ekipman\u0131n\u0131n di\u011fer par\u00e7alar\u0131ndan kopan par\u00e7alard\u0131r; bunlar a\u015f\u0131narak f\u0131r\u0131n i\u00e7inde s\u00fcr\u00fcklenir. Akan al\u00fcminyum ak\u0131\u015f\u0131nda baz\u0131 par\u00e7ac\u0131klar, intermetalik bile\u015fiklerin, bor\u00fcrlerin, karb\u00fcrlerin veya di\u011fer al\u00fcminyum bile\u015fiklerinin (klor\u00fcr gibi) \u00e7\u00f6kelmesi gibi \u00e7\u00f6z\u00fcnmeyen safs\u0131zl\u0131klar\u0131n \u00e7\u00f6kelmesidir. Erimi\u015f al\u00fcminyum kat\u0131la\u015ft\u0131ktan sonra bu safs\u0131zl\u0131klar nihai d\u00f6k\u00fcm \u00fcr\u00fcnde ortaya \u00e7\u0131kt\u0131\u011f\u0131nda, nihai \u00fcr\u00fcn\u00fcn s\u00fcnekli\u011finin azalmas\u0131na veya nihai \u00fcr\u00fcn\u00fcn son i\u015flem \u00f6zelliklerinin zay\u0131f olmas\u0131na neden olabilirler. Bu nedenle, erimi\u015f al\u00fcminyum ak\u0131\u015f\u0131n\u0131 kat\u0131 hale getirmeden \u00f6nce, bu ak\u0131\u015ftan s\u00fcr\u00fcklenen kat\u0131 maddelerin uzakla\u015ft\u0131r\u0131lmas\u0131 arzu edilir; elde edilen kat\u0131 al\u00fcminyum, oldu\u011fu gibi kullan\u0131labilir veya haddeleme, d\u00f6vme, ekstr\u00fczyon ve benzeri \u015fekillendirme i\u015flemlerine tabi tutulabilir.<\/p>\n
S\u0131v\u0131dan s\u00fcr\u00fcklenen kat\u0131 maddelerin ayr\u0131\u015ft\u0131r\u0131lmas\u0131na y\u00f6nelik filtreleme i\u015flemi, g\u00f6zenekli filtre malzemeleri arac\u0131l\u0131\u011f\u0131yla ger\u00e7ekle\u015ftirilir. Genel olarak, erimi\u015f metallerin, \u00f6zellikle de al\u00fcminyumun filtrelenmesi \u00f6zel sorunlar ortaya \u00e7\u0131kar\u0131r; zira bu s\u0131v\u0131lar olduk\u00e7a a\u015f\u0131nd\u0131r\u0131c\u0131d\u0131r ve bu s\u0131v\u0131lara dayanabilecek bir filtre malzemesi bulmak zordur.<\/p>\n
Genel olarak, d\u00f6k\u00fcm \u00f6ncesinde erimi\u015f al\u00fcminyum ala\u015f\u0131mlar\u0131ndan s\u00fcr\u00fcklenen kat\u0131 maddeleri gidermek i\u00e7in iki filtreleme y\u00f6ntemi kullan\u0131l\u0131r. En yayg\u0131n filtre malzemesi, metal aktar\u0131m tank\u0131na, noz\u00fcl\u00fcn yak\u0131n\u0131na veya kat\u0131la\u015fm\u0131\u015f k\u00fcl\u00e7enin \u00fczerindeki erimi\u015f metal havuzuna yerle\u015ftirilen a\u00e7\u0131k dokumal\u0131 cam kuma\u015f s\u00fczgektir. Bu filtreler, metalden yaln\u0131zca daha b\u00fcy\u00fck boyutlu kal\u0131nt\u0131lar\u0131 giderebilir ve erimi\u015f al\u00fcminyumun s\u0131cakl\u0131\u011f\u0131nda cam elyaflar\u0131 \u00e7ok zay\u0131flad\u0131\u011f\u0131ndan kullan\u0131m s\u0131ras\u0131nda kolayca k\u0131r\u0131l\u0131r. Bir ba\u015fka \u00f6nceki teknik y\u00f6nteminde, erimi\u015f al\u00fcminyum, tabular al\u00fcmina gibi gev\u015fek al\u00fcmina par\u00e7ac\u0131klar\u0131ndan olu\u015fan bir yatak \u00fczerinden s\u00fcz\u00fcl\u00fcr; ancak bu y\u00f6ntem, genellikle yatak filtreleriyle ili\u015fkili dezavantajlardan muzdariptir; yani \u00e7ok fazla kat\u0131 maddenin ge\u00e7mesine izin verir ve bu durum g\u00fc\u00e7l\u00fc bir e\u011filimdir. Etkili kullan\u0131m i\u00e7in kanallar\u0131n olu\u015fumu engellenir ve filtrenin g\u00f6zenek boyutu kontrol edilmesi kolay de\u011fildir; ancak kullan\u0131m ko\u015fullar\u0131 alt\u0131nda kolayca de\u011fi\u015fir, bu nedenle ba\u015flang\u0131\u00e7taki boyut uygun olsa bile bu boyut etkili bir \u015fekilde korunamaz. Ayr\u0131ca, filtre kullan\u0131lmad\u0131\u011f\u0131nda metalin s\u00fcrekli erimi\u015f halde tutulmas\u0131 gerekir.<\/p>\n
