Proses pemurnian di pengecoran aluminium terutama bertujuan untuk menghilangkan serpihan lapisan pelapis, berbagai bentuk inklusi terak non-logam seperti klorida dan karbida dalam fluks, serta partikel intermetalik berukuran kasar.<\/strong><\/p>\n

Kualitas aluminium cair sangat penting, karena sangat memengaruhi kinerja proses selanjutnya serta kualitas produk akhir. Oleh karena itu, negara-negara di seluruh dunia sangat mengutamakan proses pemurnian aluminium cair.<\/p>\n

Paduan aluminium filter busa keramik<\/a> memberikan manfaat besar bagi foil lembaran dan produk-produknya (seperti bahan baku kaleng, bahan pelapis mobil, pelat cetak PS, dan sebagainya) setelah proses pemurnian aluminium cair.<\/p>\n

\"Pemurnian<\/p>\n

Penggunaan pelat filter busa keramik di industri pengolahan aluminium Tiongkok kini semakin populer. Proses pemurnian di pabrik pengecoran aluminium umumnya dilakukan dengan 2 cara<\/strong>
\nPada jalur pengecoran semi-kontinu paduan aluminium, logam cair dimurnikan dengan semprotan fluks di dalam tungku, sedangkan pelat keramik berbusa digunakan di luar tungku untuk penyaringan. Pelat filter keramik paduan aluminium diganti setiap kali proses pengecoran, dan saat ini juga terdapat pabrik pengolahan aluminium. Tambahkan deaerator online tipe palung sebelum penyaringan untuk meningkatkan efektivitas pemurnian<\/p>\n

Yang pertama adalah menentukan siklus penggantian berdasarkan selisih tekanan antara bagian depan dan belakang pelat saring paduan aluminium pada jalur pengecoran dan penggulungan berkelanjutan. Adapun ukuran pelat saring paduan aluminium yang akan dipilih, hal tersebut ditentukan berdasarkan laju aliran cairan aluminium per satuan waktu dan jumlah total cairan aluminium.
\nPemilihan pelat filter keramik berbahan paduan aluminium berpori dengan jumlah jaring dan pori yang banyak ditentukan berdasarkan persyaratan kebersihan aluminium cair hasil akhir. Semakin tinggi persyaratan kebersihan aluminium cair tersebut, semakin kecil ukuran pori yang dipilih.
\nPemurnian dengan filtrasi busa keramik merupakan tahap terakhir dalam proses pemurnian aluminium cair. Sebelum tahap ini, telah dilakukan proses penyemprotan fluks atau penghilangan gas secara rotari dalam aliran (on-line), sehingga partikel hidrogen sebagai fase pengotor dalam aluminium cair yang belum terpisahkan menjadi lebih halus dan tersebar merata.<\/p>\n

Selama pengangkutan dan penggunaan pelat filter dari paduan aluminium<\/strong>, pelat filter paduan aluminium harus mampu menahan dampak tekanan eksternal tertentu, sehingga kami juga telah memasukkan indeks kekuatan tekan sebagai ukuran kualitas pelat filter paduan aluminium selama proses pengembangan standar ini. Hal ini menjadi salah satu tolok ukur kualitas yang baik atau buruk. Semakin tinggi kekuatan tekan, semakin luas penggunaan produk tersebut, dan semakin baik kualitasnya; sebaliknya, semakin rendah kekuatan tekan, semakin terbatas penggunaan produk tersebut, dan semakin buruk kualitasnya.<\/p>\n

Saat aliran dilepaskan untuk proses pengecoran, cairan aluminium bersuhu tinggi tiba-tiba bersentuhan dengan permukaan pelat saringan paduan aluminium, dan pelat saringan tersebut memanas dalam hitungan sepersepuluh detik. Panas dari cairan aluminium membuat pelat filter paduan aluminium dengan cepat naik hingga mendekati suhu logam, dan pelat filter paduan aluminium mengalami ekspansi termal seketika, yang mengharuskan pelat filter paduan aluminium memiliki koefisien ekspansi termal yang kecil dan tidak akan retak setelah dipanaskan; dan karena pelat filter paduan aluminium yang terendam dalam cairan aluminium akan bertahan selama jangka waktu tertentu, pelat tersebut tidak boleh tercuci atau melunak selama proses kerja. Terdeformasi.<\/p>","protected":false},"excerpt":{"rendered":"
