Paduan aluminium dengan proses penghalusan butiran berupa partikel bubuk, yang disemprotkan oleh gas pembawa (nitrogen atau argon) melalui alat penyemprot khusus untuk penghalusan bubuk ke dasar kolam cairan aluminium, sehingga membentuk banyak gelembung di dalam cairan aluminium, dan gelembung-gelembung tersebut naik dari dasar cairan aluminium.
\nSelama proses pengapungan, bahan tersebut berada dalam kontak penuh dengan aluminium cair. Melalui reaksi fisik dan kimia, gas dan inklusi dalam aluminium cair didorong ke permukaan aluminium cair untuk mencapai tujuan penghilangan gas dan penghilangan terak secara bersamaan.
\nSetelah serangkaian uji coba industri yang luas, telah terbukti bahwa formulasi yang telah disempurnakan ini memiliki pengaruh yang signifikan terhadap proses penghilangan gas dan penghilangan terak pada aluminium murni dan paduan aluminium.<\/p>\n

\"Paduan<\/p>\n

Rentang adaptasi dan takaran paduan aluminium untuk pemurnian biji-bijian
\n1. Bahan semprotan umum: ketika kadar gas terak tinggi, lakukan penghilangan gas dan pembuangan terak pada paduan aluminium non-magnesium tinggi dan aluminium murni.
\n2. Agen penyemprotan bubuk penghilang gas: semua paduan aluminium\u2014kecuali yang berkadar magnesium tinggi\u2014umumnya telah melalui proses penghilangan gas dan digunakan untuk bahan tungku yang sangat mencemari. Kadar gas dalam cairan logam cukup tinggi, dan gelembung-gelembung pada hasil cor merupakan masalah kualitas utama.
\nSelalu ada kesempatan.
\n3. Bahan semprot bubuk untuk penghilangan terak: terutama digunakan untuk menghilangkan terak, cocok untuk permukaan yang luas, serta kandungan inklusi oksida yang tinggi, terutama pada lelehan bahan halus yang telah dihancurkan yang mengandung inklusi non-logam dalam coran.
\nKejadian-kejadian utama yang berkaitan dengan masalah kualitas.
\n4. Pemurnian: baik penghilangan gas maupun penghilangan terak memiliki fungsi pemurnian, yang cocok untuk paduan aluminium dengan kandungan aluminium murni dan paduan aluminium-silikon kurang dari 4%
\n5. Pemurnian dan modifikasi: Paduan Al-Si, penghilangan gas, penghilangan terak, dan modifikasi.<\/p>\n

Karakteristik dari bahan pengendap aluminium<\/a>
\nProsesnya sederhana dan praktis, mengurangi beban kerja para pekerja, meningkatkan tingkat pemanfaatan bahan pemurnian, serta secara efektif melakukan penghilangan terak, penghilangan gas, dan pemurnian.<\/p>\n

Tindakan pencegahan
\n1. Atur kecepatan pengumpanan bubuk dengan mengatur posisi katup di bagian bawah tangki pemurnian, dan semprotkan fluks sebanyak mungkin selama proses pemurnian.
\n2. Atur ketinggian pengadukan aluminium cair dengan mengontrol tekanan nitrogen. Dengan syarat tidak terjadi penyumbatan, tingkat pengadukan akan lebih baik jika ketinggiannya di bawah 15 cm.<\/p>\n

Keunggulan produk paduan aluminium dengan struktur kristal yang lebih halus
\n1. Konsentrat aluminium dan paduan aluminium berbentuk partikel bubuk, dan luas permukaan kontak konsentrat curah dengan aluminium cair lebih besar.
\n2. Efek penghilangan gas dan penghilangan terak yang baik. Cairan pemurnian yang disemprotkan ke dasar kolam cairan dan dasar tungku mengalami reaksi fisik dan kimia, yang dapat melelehkan alumina dan memisahkan terak dari aluminium.
\nGas tersebut dialirkan ke permukaan aluminium cair untuk menjaga kebersihan dasar tungku, yang secara signifikan mengurangi frekuensi pembersihan tungku, meningkatkan tingkat pemanfaatan tungku, dan mengurangi beban kerja
\nPada saat yang sama, proses degassing memisahkan oksida dan kotoran dari cairan logam, dan terak yang terbentuk dikeringkan sehingga mudah dipisahkan dari logam, yang pada gilirannya meningkatkan tingkat pemanfaatan logam dan mengurangi endapan pada dinding tungku.
\nAdhesi terak memudahkan proses pembersihan dan pemeliharaan tungku serta meningkatkan kualitas lingkungan kerja.<\/p>","protected":false},"excerpt":{"rendered":"
