\"Al\u00fcminyum<\/p>\n

Bir Gaz Giderme Sistemi Erimi\u015f Al\u00fcminyuma Asl\u0131nda Ne Yapar?<\/h2>\n

S\u0131v\u0131 haldeki al\u00fcminyum, atmosferdeki nemden, nemli hammadde i\u00e7inden, yanma yan \u00fcr\u00fcnlerinden ve hatta hurda \u00fczerinde kalan ya\u011f ve greslerden hidrojen emer. S\u0131v\u0131 al\u00fcminyumdaki hidrojen \u00e7\u00f6z\u00fcn\u00fcrl\u00fc\u011f\u00fc, kat\u0131 al\u00fcminyumdakinden \u00e7ok daha y\u00fcksektir; bu da metal so\u011fuyup kat\u0131la\u015f\u0131rken, fazla hidrojenin d\u00f6k\u00fcm\u00fcn i\u00e7indeki mikroskobik bo\u015fluklara girmesinden ba\u015fka bir se\u00e7ene\u011fi olmad\u0131\u011f\u0131 anlam\u0131na gelir. Bu bo\u015fluklar daha sonra g\u00f6zeneklilik olarak ortaya \u00e7\u0131kar ve g\u00f6zeneklilik, d\u00f6k\u00fcmlerin r\u00f6ntgen muayenesinde reddedilmesinin veya y\u00fck alt\u0131nda ba\u015far\u0131s\u0131z olmas\u0131n\u0131n bir numaral\u0131 nedenidir.<\/p>\n

Bir gaz giderme \u00fcnitesi, eriyik i\u00e7inden bir temizleme gaz\u0131 ge\u00e7irerek bu sorunu \u00e7\u00f6zer. Temizleme gaz\u0131n\u0131n hidrojen k\u0131smi bas\u0131nc\u0131 neredeyse s\u0131f\u0131rd\u0131r; bu nedenle al\u00fcminyumda \u00e7\u00f6z\u00fcnm\u00fc\u015f hidrojen, kabarc\u0131klar\u0131n i\u00e7ine yay\u0131l\u0131r ve onlarla birlikte yukar\u0131 do\u011fru y\u00fckselir. Kabarc\u0131klar ne kadar k\u00fc\u00e7\u00fck ve \u00e7ok say\u0131da olursa, bu dif\u00fczyon i\u00e7in o kadar fazla y\u00fczey alan\u0131 mevcuttur; i\u015fte bu nedenle rotor tasar\u0131m\u0131 ve kabarc\u0131k da\u011f\u0131l\u0131m\u0131, ham gaz ak\u0131\u015f h\u0131z\u0131ndan \u00e7ok daha \u00f6nemlidir.<\/p>\n

Belirli bir noktadan sonra, b\u00fcy\u00fck kabarc\u0131klar eriyik i\u00e7inden o kadar h\u0131zl\u0131 ge\u00e7iyorlar ki hidrojeni verimli bir \u015fekilde alam\u0131yorlar ve eriyik kalitesini iyile\u015ftirmeden inert gaz\u0131 bo\u015fa harc\u0131yorsunuz. Bu, m\u00fc\u015fterilerimizin kurulumlar\u0131n\u0131 denetlerken s\u00fcrekli olarak d\u00fczeltti\u011fimiz bir hatad\u0131r.<\/p>\n

Y\u00fckselen gaz kabarc\u0131klar\u0131 minik y\u00fczd\u00fcrme ara\u00e7lar\u0131 gibi davranarak, kal\u0131nt\u0131lar\u0131 yukar\u0131 do\u011fru s\u00fcr\u00fckleyip c\u00fcruf tabakas\u0131na ta\u015f\u0131r; burada da bu kal\u0131nt\u0131lar s\u0131y\u0131r\u0131larak uzakla\u015ft\u0131r\u0131labilir.

    Al\u00fcminyum gaz giderme i\u015fleminde genellikle hangi gaz kullan\u0131l\u0131r?<\/strong>
    \nAzot, maliyet ve temin edilebilirlik nedeniyle en yayg\u0131n tercih edilen se\u00e7enektir; argon ise hidrojen gideriminin biraz daha iyile\u015ftirilmesi gereken uygulamalarda veya belirli ala\u015f\u0131m i\u015fleme gereksinimleri olan durumlarda kullan\u0131l\u0131r.<\/p>\n

    D\u00f6ner gaz giderici cihaz\u0131nda rotor ve mil ne s\u0131kl\u0131kla de\u011fi\u015ftirilmelidir?<\/strong>
    \nY\u00fcksek verimli i\u015flemlerde grafit bile\u015fenlerin genellikle \u00fc\u00e7 ila alt\u0131 haftada bir de\u011fi\u015ftirilmesi gerekirken, CFC rotorlar\u0131 ve milleri benzer ko\u015fullar alt\u0131nda genellikle iki ila \u00fc\u00e7 ay veya daha uzun s\u00fcre dayan\u0131r.<\/p>\n

    Sadece gaz giderme i\u015flemi, g\u00f6zeneksiz d\u00f6k\u00fcmleri garanti edebilir mi?<\/strong>
    \nHay\u0131r. Gaz giderme i\u015flemi hidrojen kaynakl\u0131 g\u00f6zeneklili\u011fi giderir; ancak yetersiz kanal a\u00e7ma veya kat\u0131la\u015fma tasar\u0131m\u0131 nedeniyle olu\u015fan b\u00fcz\u00fclme g\u00f6zeneklili\u011fi, kal\u0131p veya kal\u0131p tasar\u0131m\u0131 a\u00e7\u0131s\u0131ndan ayr\u0131 proses d\u00fczeltmeleri gerektirir.<\/p>\n
