Zirkonia Cff<\/strong><\/p>\n

Saat menggunakan Zirconia Cff, inklusi ditangkap oleh filter yang dipasang di jalur aliran logam. Filter tersebut menangkap lapisan oksida, namun tidak menangkap inklusi berukuran kecil. Penyaringan yang lebih efisien dapat dicapai dengan menggunakan filter busa keramik (PCF), yang merupakan struktur keramik berpori di mana logam cair mengalir melalui jalur yang berliku-liku.<\/p>\n

Disarankan untuk memasang Zirconia Cff pada bagian-bagian peralatan pengecoran yang memerlukan kapasitas produksi tinggi, misalnya pada saluran-saluran cetakan tuang.<\/p>\n

Keunggulan utama PCF: hambatan minimal terhadap logam cair yang diproses; ketahanan terhadap suhu tinggi dan kekuatan mekanis; serta tingkat pemrosesan logam cair dan paduan yang benar-benar baru.<\/p>\n

Penggunaan filter busa keramik<\/a> memungkinkan diperolehnya logam murni secara metalurgi dengan kualitas tinggi.
\nPenangkapan yang efektif terhadap inklusi yang tersebar di dalam logam cair meningkatkan kualitas coran, tidak hanya dari segi kebersihan internal, tetapi juga kualitas permukaan dan kekuatan mekanis.
\nSelain itu, penggunaan filter membantu proses pelepasan gas dari lelehan. Namun, kelemahan utama dari metode ini adalah biaya PCF yang masih tinggi, serta kebutuhan akan pemanasan berlebih pada lelehan untuk memudahkan proses penyalaan dan pengoperasian filter.
\nSelain itu, Zirconia Cff memerlukan penggunaan alat khusus untuk mengokohkannya selama operasi.<\/p>\n

Upaya untuk mengatasi kekurangan-kekurangan tersebut juga sedang dilakukan.<\/strong>
\nOleh karena itu, di Departemen Proses Pengecoran dan Metalurgi serta Paduan Logam, Universitas Teknik Negeri N. Novgorod, telah dikembangkan sebuah teknologi inovatif untuk memproduksi PCF dari bahan-bahan murah yang tidak langka\u2014yaitu limbah dari industri metalurgi dan kimia.
\nEvaluasi efisiensi pembersihan logam cair aluminium dalam cetakan menggunakan PCF yang diproduksi dengan teknologi baru tersebut dilakukan dalam kondisi produksi dan laboratorium pada paduan AK5M2.
\nKami meneliti mode-mode teknologi dan parameter filtrasi: durasi penuangan, hidrodinamika aliran logam cair dalam sistem saluran, mode filtrasi termal, interaksi kimia antara filter dengan logam cair, kekuatan mekanis PCF pada suhu tinggi, ukuran sel-sel filter berpori, dan lain-lain.
\nDalam hal ini, PCF dapat dipasang di mana saja dalam sistem gerbang, di dalam wadah tuang sebagai sekat internal, dan sebagainya.<\/p>\n

Pada tahap-tahap awal penelitian ini, PCF dipasang di dalam cangkir katup di pintu masuk pipa naik.
\nPCF digunakan dengan ketebalan 15 mm, porositas 85%, serta ukuran sel rata-rata 2,5 hingga 3 mm.
\nLogam aluminium cair dituangkan pada suhu 730 \u00b0C ke dalam cetakan pendingin yang dipanaskan hingga suhu 250 \u00b0C.
\nBagian cor tersebut memiliki bagian silinder tengah yang sangat besar dengan flensa atas dan bawah serta massa sebesar 6 kg.<\/p>","protected":false},"excerpt":{"rendered":"
