Penghilangan Gas Hidrogen pada Pengecoran<\/strong> adalah rotor berputar yang memecah nitrogen (atau argon) yang ditiupkan ke dalam logam aluminium cair menjadi sejumlah besar gelembung-gelembung yang tersebar, yang kemudian tersebar di dalam logam cair tersebut.
\nGelembung tersebut memanfaatkan perbedaan tekanan parsial gas dan prinsip adsorpsi permukaan untuk menyerap hidrogen dan terak teroksidasi dalam cairan logam.
\nSaat gelembung-gelembung tersebut naik, gelembung-gelembung tersebut diangkat dari permukaan cairan untuk memurnikan cairan tersebut.
\nKarena gelembung-gelembung tersebut berukuran halus dan tersebar merata, gelembung-gelembung tersebut tercampur dan meleleh secara merata seiring putaran, kemudian berputar membentuk spiral, perlahan-lahan naik ke atas, dan bersentuhan dengan logam cair dalam waktu yang lama; sehingga laju aliran gas yang dihasilkan terus meningkat tanpa membentuk endapan, sehingga hidrogen berbahaya dalam logam cair aluminium dapat dihilangkan, dan efektivitas pemurnian pun meningkat secara signifikan.<\/p>\n

Pengecoran aluminium komposit yang telah melalui proses penghilangan gas didasarkan pada teknologi pengecoran bertekanan rendah dengan pompa elektromagnetik sebagai inti utamanya, teknologi pemurnian komposit melalui peleburan dan pembentukan aluminium sebagai inti utamanya, serta teknologi modern untuk produksi coran aluminium.
\nKeunggulan berupa aliran yang stabil, pengendalian aliran yang praktis, pengurangan proses penyedotan aluminium cair, serta kemudahan penerapannya memungkinkan otomatisasi proses penggunaan, yang tidak hanya meningkatkan kualitas coran aluminium, tetapi juga memperbaiki lingkungan kerja. Hal ini mewujudkan otomatisasi dan produksi coran yang modern.<\/p>\n

\"Penghilangan<\/p>\n

Penghilangan Gas Hidrogen pada Pengecoran<\/strong>
\nDi fasilitas peleburan aluminium dan pemurnian komposit, selain kinerja terkait inklusi logam, salah satu aspek penting dari hasil cor paduan enamel cair yang telah dimurnikan adalah kinerja degassing yang tinggi dari filter keramik semprot dan busa berputar.
\nAlat ini berukuran besar, menggunakan bahan pelapis baru yang tahan lama, dan dilengkapi dengan sistem pengawetan panas\/pemanasan mandiri, sehingga dapat digunakan untuk produksi massal berkelanjutan maupun produksi secara berkala.
\nTeknologi ini memiliki efisiensi pemurnian yang tinggi, masa pakai yang lama, kalibrasi yang efektif, pemasangan yang mudah, serta fleksibilitas dalam penggunaan aluminium cair.
\nUntuk mengatasi masalah-masalah kompleks terkait coran aluminium berkualitas tinggi, ada tiga aspek utama yang harus diperhatikan:<\/strong>
\n(1) Peleburan dan pengolahan aluminium cair,
\n(2) Transisi yang mulus saat lelehan lampu halida aluminium meleleh,
\n(3) Proses cetakan logam dan inti pasir memiliki stabilitas dimensi yang baik.<\/p>\n

Terdapat banyak peralatan pengecoran cetakan dan pengecoran<\/strong> untuk peleburan paduan aluminium yang tersedia di pasaran, termasuk tungku peleburan terpusat, tungku cawan, tungku kolam cair, dan tungku penahan listrik.
\nOleh karena itu, penghilangan gas dari aluminium<\/a> Peralatan ini juga dapat disesuaikan sesuai dengan jenis peralatan peleburan paduan aluminium, dan dapat dibuat menjadi deaerator pemurnian bergerak, deaerator pemurnian tetap, serta deaerator pemurnian suspensi.
\nAda tiga keadaan hidrogen yang terlarut dalam aluminium cair (keadaan atom, molekul, dan kompleks; hanya molekul hidrogen yang dapat membentuk pori-pori; molekul hidrogen dan atom hidrogen berada dalam keadaan kesetimbangan dinamis; serta molekul hidrogen dan hidrida langsung mengambil bentuk yang berbeda selama proses kristalisasi logam). Terpisah (Atom hidrogen tersebar di permukaan logam, lalu meninggalkan keadaan adsorpsi. Ketika beberapa gelembung tidak dapat naik ke antarmuka, gelembung tersebut akan tetap berada di dalam logam cair, sehingga menyebabkan pori-pori pada coran.).<\/p>","protected":false},"excerpt":{"rendered":"
