Flux butiran bebas natrium menghilangkan inklusi non-logam, hidrogen, natrium, kalsium, dan litium dari aluminium cair dan paduan aluminium.<\/strong><\/p>\n

Produk ini diproduksi dalam bentuk partikel halus maupun butiran. SCOT-MAG bereaksi dengan cepat dan efisien untuk menghilangkan natrium, litium, dan kalsium dari aluminium cair dan paduan aluminium, serta dari lapisan tahan api tungku.
\nKadar natrium di bawah 1 ppm pada paduan aluminium dengan kandungan Mg tinggi dapat dicapai dalam proses pengecoran.<\/p>\n

\"Flux<\/p>\n

Flux butiran bebas natrium menghilangkan berbagai inklusi nonlogam seperti oksida, karbida, dan borida, serta meningkatkan proses penghilangan gas saat disuntikkan.<\/strong><\/p>\n

Metode pemurnian gas campuran. Campuran klorin dan nitrogen digunakan untuk memurnikan aluminium cair<\/a>. Perannya adalah untuk menghilangkan hidrogen dan memisahkan oksida di satu sisi, serta menghilangkan beberapa pengotor logam (seperti magnesium) dalam aluminium di sisi lain. Komposisi yang umum digunakan adalah 90% nitrogen + 10% klorin. . Ada juga komposisi 10% klorin + 10% karbon dioksida + 80% nitrogen. Efeknya lebih baik, karena karbon dioksida dapat mendifusikan klorin dan nitrogen dengan baik, sehingga dapat mempersingkat waktu operasi.<\/p>\n

Gas yang terkandung dalam lelehan paduan aluminium sebagian besar berupa hidrogen (fraksi volumenya sekitar 80%~90%), diikuti oleh nitrogen, oksigen, karbon monoksida, dan sebagainya.<\/strong>
\nMeskipun kandungan hidrogen dalam logam cair paduan aluminium tidak terlalu tinggi jika dibandingkan dengan logam lain, hidrogen hampir tidak larut dalam aluminium padat, sedangkan kelarutannya dalam aluminium cair sangat tinggi, dan nilainya meningkat seiring dengan kenaikan suhu.
\nKelarutan hidrogen pada garis fase padat adalah 0,65 mL dan 0,034 mlL per 100 g kandungan hidrogen dalam aluminium cair (H pada 0,1 MPa), artinya, perbedaan kelarutan hidrogen pada fase padat-cair adalah sekitar 19,1 kali; karena perbedaan kelarutan tersebut, hidrogen cenderung keluar dari logam cair. Ketika tekanan hidrogen lebih besar daripada tegangan permukaan dan tekanan hidrostatik, gelembung akan terbentuk, dan kemudian pori-pori terbentuk pada coran atau ingot.
\nOleh karena itu, dalam proses pemurnian logam cair paduan aluminium, masalah utamanya adalah tingginya kandungan hidrogen pada paduan aluminium, dan teknologi pemurnian melalui penghilangan gas pada logam cair aluminium tidak dapat memenuhi persyaratan produksi komponen paduan aluminium berkualitas tinggi.
\nSecara umum, kandungan hidrogen berkisar antara 0,1 hingga 0,2 mL per 100 g aluminium, dan produk paduan aluminium yang digunakan dalam industri kedirgantaraan memiliki persyaratan kualitas yang lebih tinggi. Sebagai contoh, bahan aluminium untuk komponen pesawat terbang harus memiliki kandungan hidrogen tidak lebih dari 0,06 mL per 100 g.<\/p>","protected":false},"excerpt":{"rendered":"
