Pengecoran Busa Aluminium yang Meleleh awalnya dikembangkan untuk penempaan paduan aluminium.<\/strong>
\nPaduan aluminium tempa ini memerlukan tingkat kebersihan yang ketat agar dapat memenuhi persyaratan aplikasi produk yang ketat, seperti kaleng dan tutup aluminium, foil aluminium, bahan ekstrusi pesawat terbang, papan memori, bahan tempa, dan kawat logam.<\/p>\n

Aluminium cair hanya dapat mengalir melalui jaring yang berliku-liku pada cakram saringan, sedangkan inklusi yang terbawa olehnya mengalir menyusuri saluran dan pori-pori yang berliku-liku tersebut.
\nBerkat interaksi antara gaya gesek akibat tekanan aksial aliran cairan, gaya adsorpsi permukaan gandum, dan gaya kimia, partikel tersebut menempel dengan kuat pada permukaan bagian dalam lubang saringan dan celah-celahnya, sehingga memisahkannya dari fase cair logam.<\/p>\n

Efek sisa dari filter yang dikembangkan oleh Produsen Filter Keramik<\/a> Teknologi AdTech bergantung pada ukuran pori dan ketebalan cakram filter, serta kecepatan aliran aluminium cair yang melewati cakram filter tersebut. Semakin tebal filternya, semakin lama aliran aluminium cair melewati filter, semakin besar kemungkinan terjadinya tabrakan, dan semakin besar pula kemungkinan inklusi tertahan, mengendap, dan teradsorpsi.<\/p>\n

\"Peleburan<\/p>\n

Peleburan Aluminium, Pengecoran Busa Aluminium<\/strong> Secara umum, hal ini dibagi menjadi 6 ukuran pori: 10PPI, 15PPI, 20PPI, 25PPI, 30PPI, dan 40PPI. Semakin besar angkanya, semakin kecil ukuran pori-porinya. Namun, dalam praktiknya, keempat jenis tersebut\u201410PPI, 20PPI, 30PPI, dan 40PPI\u2014sudah dapat memenuhi kebutuhan pelanggan.<\/p>\n

Pemilihan bukaan lensa<\/strong>
\n1. Pengecoran: 10\u201325 ppi
\n2. Pengecoran semi-kontinu: 30\u201360 ppi
\n3. Aluminium atau lembaran berkualitas tinggi: 50\u201360 ppi
\n4. Pengecoran dan penggulungan berkelanjutan: 50\uff5e60p<\/p>\n

Perlu dicatat bahwa ketika kecepatan aliran filtrat yang melewati filter keramik terlalu rendah<\/strong>, partikel inklusi kecil sulit terserap karena probabilitas tabrakan yang rendah, sehingga mengalir melalui pori-pori filter secara \u201cstabil\u201d. Jika kecepatannya terlalu tinggi, aliran logam cair akan \u201cmenyapu\u201d inklusi padat dan mungkin membawanya pergi. Laju aliran yang optimal sebaiknya ditentukan berdasarkan praktik produksi.<\/p>\n

Dibandingkan dengan solusi tradisional, keseragaman dan integritas struktural desain pelat lubang pada filter baru ini juga secara signifikan mengurangi turbulensi serta sangat efektif mencegah reoksidasi yang disebabkan oleh udara yang terperangkap. Bahkan, hampir tidak ada kotoran yang masuk ke dalam cetakan, sehingga mengurangi pekerjaan ulang, meningkatkan kualitas permukaan, menurunkan tingkat limbah, dan pada akhirnya meningkatkan profitabilitas.<\/p>\n

Selama proses peleburan paduan aluminium, inklusi non-logam akan terbentuk akibat bahan baku yang tidak bersih serta pengaruh lingkungan eksternal. Selama proses pengecoran, akibat turbulensi, jatuhnya, dan percikan logam, lapisan oksida yang terbentuk akibat kontak antara area luas logam cair dengan udara juga ikut tercampur ke dalam aluminium cair. Oleh karena itu, meskipun bahan baku bersih dan logam cair telah dimurnikan serta dihilangkan gasnya, terak sekunder yang disebabkan oleh kondisi internal dan aliran logam cair harus dihilangkan lebih lanjut, dan efek penyaringan ulang sangat signifikan.
\nPada prinsipnya, posisi pemasangan filter harus sedemikian rupa sehingga lelehan aluminium yang telah disaring tidak mengalir ke dalam kristalisator dan tidak tumpah. Untuk sistem proses hierarkis, berkat fungsi saluran pembimbing, lapisan permukaan cairan di pelat aliran bersifat kontinu dan dilengkapi dengan filter. Lokasi tersebut tidak perlu terlalu dekat dengan perangkat kristalisasi benang.<\/p>","protected":false},"excerpt":{"rendered":"
