Penghilangan Gas dalam Pengecoran Aluminium<\/h2>\n

 <\/p>\n

Prinsip kerja dari unit penghilang gas aluminium<\/a>:<\/h3>\n

Cairan aluminium unit penghilang gas<\/a> Merupakan peralatan bantu untuk proses pengecoran dan penuangan. Peralatan ini terdiri dari mesin pemurnian cairan aluminium yang terpasang tetap dan sistem penghilang gas yang dapat diangkat, yang dapat disesuaikan sesuai dengan ketinggian peralatan tungku milik pelanggan.<\/strong><\/p>\n

Rotor grafit yang berputar dengan kecepatan tinggi menyemprotkan gas inert, memecah gelembung-gelembung gas inert berukuran besar (argon atau nitrogen) yang masuk ke dalam logam aluminium cair menjadi gelembung-gelembung yang sangat halus, serta menyebarkannya secara merata di dalam logam cair tersebut.<\/strong><\/p>\n

Rotor yang berputar juga dapat mempercepat difusi hidrogen dan inklusi dalam logam aluminium cair. Dengan mengurangi diameter gelembung, luas permukaan total gelembung-gelembung ini secara aktif meningkat, sehingga lebih banyak luas permukaan gelembung inert yang bersentuhan dengan hidrogen dan kotoran dalam logam cair. Gelembung-gelembung dalam logam cair memanfaatkan perbedaan tekanan parsial gas dan prinsip adsorpsi permukaan untuk menyerap hidrogen dalam logam cair, mengadsorpsi terak oksida, serta membawa zat-zat berbahaya ini ke permukaan cairan saat gelembung-gelembung tersebut naik, sehingga logam cair menjadi murni.<\/strong><\/p>\n

Rotor grafit:<\/h3>\n

Rotor grafit dapat beroperasi secara terus-menerus pada kecepatan 200 r\/min\u2013400 r\/min di dalam logam aluminium cair bersuhu sekitar 750 \u00b0C.<\/strong>
\nKualitas grafit itu sendiri memiliki pengaruh yang signifikan terhadap masa pakai rotor. Jika lapisan anti-oksidasi diaplikasikan pada permukaannya, masa pakai tersebut dapat diperpanjang hingga 2\u20133 bulan.<\/strong><\/p>\n
