Filter Pengecoran Aluminium menggunakan struktur jaringan tiga dimensi dan pori-pori yang saling terhubung dari busa organik sebagai media pembawa; campuran keramik khusus yang memiliki sifat tiksotropik kemudian dimasukkan ke dalamnya, dan menggunakan proses ekstrusi gulungan khusus agar campuran keramik tersebut tersebar secara merata pada kerangka media pembawa, kemudian dikeringkan, dikeraskan, dan dipanggang pada suhu tinggi.<\/p>\n

Filter pengecoran aluminium terbuat dari aluminium oksida. Setelah penyesuaian formula dan parameter proses, filter ini juga cocok untuk silikon karbida, aluminium oksida, dan bahan-bahan lainnya.<\/p>\n

Karena sifat-sifat aluminium, paduan aluminium memiliki kecenderungan yang kuat untuk membentuk pori-pori, dan juga rentan terhadap oksidasi serta inklusi. Oleh karena itu, pencegahan dan penghilangan inklusi gas serta inklusi oksidasi telah menjadi masalah utama dalam proses peleburan paduan aluminium.
\nAgar dapat memperoleh cairan paduan aluminium berkualitas tinggi, proses peleburannya harus dikendalikan secara ketat dan harus diambil langkah-langkah untuk mengendalikannya.<\/p>\n

Filter pengecoran aluminium dapat secara efektif menyaring terak secara mekanis.<\/strong>
\nKetika logam cair mengalir melalui filter busa keramik yang memiliki struktur kompleks, media filter tersebut menyaring inklusi yang ukurannya lebih besar daripada ukuran pori permukaan filter melalui proses pemisahan mekanis, dan menyebabkan inklusi tersebut mengendap di bagian hilir aliran logam cair pada filter.
\nSeiring bertambahnya jumlah inklusi pada permukaan filter, lapisan \u201cfilter cake\u201d akan terbentuk secara bertahap, yang pada gilirannya akan semakin mempersempit saluran aliran logam cair. Oleh karena itu, permukaan media filter yang baru dapat menyaring inklusi yang lebih halus.
\nDi saat yang sama, bagian dalam media tersebut juga memiliki efek penyaringan. Di antara banyak lubang kecil yang menembus badan keramik, ada yang berbentuk celah sangat kecil, dan ada pula yang memiliki sudut-sudut mati. Area-area dengan karakteristik berbeda ini merupakan posisi-posisi potensial untuk menahan inklusi. Di dalam filter, terdapat pula efek \u201cfilter cake\u201d.<\/p>\n

Rekomendasi Adtech mengenai penggunaan Filter Pengecoran Aluminium<\/a><\/strong>
\n1. Sesuai dengan titik leleh paduan tersebut, pilihlah filter yang terbuat dari bahan yang sesuai untuk menghindari suhu yang terlalu tinggi, yang dapat merusak fungsi filter dan mengakibatkan kegagalan dalam mencapai hasil penyaringan.
\n2. Pilih jaring yang sesuai, dan hasil pemurniannya harus sesuai dengan persyaratan pengecoran.
\n3. Cobalah menggunakan batas atas T. Art sebagai suhu pengecoran untuk meningkatkan kelancaran aliran logam.
\n4. Apabila filter diletakkan secara horizontal di bawah cangkir mulut atau permukaan pemisah, ketinggian pengecoran tidak boleh melebihi 20 cm. Sebaiknya cairan logam dialirkan ke dinding cangkir mulut, bukan langsung ke filter.
\n5. Filter harus ditangani dengan hati-hati. Saat tidak digunakan, simpanlah di tempat yang kering dan berventilasi agar kelembapan yang diserap tidak memengaruhi kekuatan filter.<\/p>","protected":false},"excerpt":{"rendered":"
