Filter Busa Silikon Karbida untuk Industri Pengecoran Aluminium<\/strong><\/p>\n

Kualitas aluminium cair sangat penting, karena hal ini sangat memengaruhi sifat-sifat pengolahan selanjutnya serta kualitas produk akhir. Oleh karena itu, semua negara di dunia sangat mementingkan proses pemurnian aluminium cair.
\nAda banyak penyebab polusi aluminium. Di satu sisi, selama proses peleburan, aluminium terpapar pada atmosfer tungku dalam keadaan cair atau setengah cair, sehingga rentan terhadap oksidasi, mudah bereaksi dengan uap air untuk menyerap hidrogen, dan mudah membentuk berbagai jenis terak non-logam. (seperti serpihan lapisan tungku, klorida, karbida, dan sebagainya dalam fluks) serta partikel intermetalik kasar dan sejenisnya.
\nDi sisi lain, sebagian bahan limbah dalam campuran bahan baku mengandung beberapa pengotor non-aluminium selama proses sirkulasi. Karena limbah tersebut berasal dari limbah proses, limbah potongan, dan limbah dari luar lokasi pada setiap tahap proses di pabrik, rutenya berbeda-beda, komposisinya kompleks, dan kualitasnya pun buruk.
\nPengotor-pengotor ini cenderung menyebabkan terbentuknya gelembung dan inklusi pada lempengan, yang secara serius memengaruhi kemurnian logam cair, sehingga pada gilirannya juga memengaruhi sifat-sifat pengolahan, sifat-sifat mekanis, ketahanan terhadap korosi, serta kualitas penampilan produk.
\nProses penyaringan berkelanjutan terhadap aluminium cair menggunakan pelat filter keramik berbusa merupakan proses pengolahan berkelanjutan yang dilakukan di luar tungku, dan operasi pemurnian tersebut terutama mencakup penghilangan terak.<\/p>\n

Filter Busa Silikon Karbida telah digunakan untuk menghilangkan inklusi dalam cairan aluminium selama lebih dari 30 tahun.<\/strong>
\nSetelah berhasil diterapkan dalam praktik produksi, bahan ini dengan cepat menggantikan filter kaca, tabung keramik mikropori, bola alumina, dan media filter lainnya.<\/p>\n

Pelat filter keramik berbusa memiliki struktur berlubang seperti jaring dan memiliki kekuatan tertentu; pelat ini mampu menahan perbedaan tekanan akibat ketinggian cairan logam serta benturan aliran logam, namun bersifat rapuh dan mudah pecah, karena bahan tersebut memiliki struktur yang presisi dan kualitas yang baik, serta memiliki luas permukaan yang besar, sehingga hasil penyaringannya sangat baik.<\/p>\n

Keuntungan menggunakan Filter Busa Silikon Karbida untuk memurnikan aluminium<\/strong>
\nSetelah pelat filter keramik berbusa<\/a> Proses ini memurnikan cairan aluminium, sehingga memberikan manfaat besar bagi lembaran foil dan produk-produknya (seperti kaleng, hiasan berkilau untuk mobil, pelat cetak PS, dan sebagainya). Adapun bagi produsen profil paduan aluminium, berikut adalah beberapa keunggulan yang jelas:
\n1. Meningkatkan produktivitas ekstrusi
\nSaat menggunakan pelat saring untuk memurnikan bahan baku ekstrusi paduan 6063, kami memantau cetakan tertentu dan menemukan bahwa kecepatan ekstrusi meningkat sekitar 20% serta produktivitas meningkat hampir 15%.
\n2. Memperpanjang masa pakai cetakan dan mengurangi frekuensi perbaikan cetakan.
\n3. Kurangi tekanan
\nKetika pelat filter digunakan untuk memurnikan logam cair paduan 6063, ditemukan bahwa gaya ekstrusi lebih dari 3% lebih rendah dibandingkan dengan yang tidak difilter.
\n4. Kualitas permukaan profil aluminium meningkat secara signifikan.
\nBerdasarkan uraian di atas, penggunaan pelat filter keramik berbusa untuk memurnikan aluminium cair memiliki keuntungan yang sangat besar dalam hal pengurangan biaya produksi dan peningkatan kualitas produk.
\nSelain itu, pelat filter keramik digunakan untuk memurnikan cairan aluminium, dan perangkat ini berupa selubung baja biasa yang dilapisi dengan tikar bata tahan api prefabrikasi. Perangkat ini dipasang secara horizontal di dalam sel aliran logam, yaitu di antara lubang aliran dan lubang pengecoran. Oleh karena itu, tidak perlu melakukan perubahan besar pada sistem pengecoran yang ada, melainkan hanya memerlukan ruang yang kecil. Selain itu, pelat filter dapat secara efektif menyaring seluruh logam dari satu proses peleburan, dan sangat mudah untuk dikeluarkan atau diganti setelah selesai digunakan. Perangkat ini juga cocok untuk sistem pengecoran horizontal maupun vertikal.<\/p>","protected":false},"excerpt":{"rendered":"
