Filter Busa Keramik Nordic<\/strong> secara efektif menghilangkan kotoran berbahaya seperti gelembung, oksida abu, dan berbagai inklusi dalam logam cair, sehingga secara mendasar menghilangkan lubang gas, lubang terak, dan lubang pasir pada coran, yang secara signifikan meningkatkan hasil produksi coran serta meningkatkan kualitas intrinsik dan kualitas penampilan coran.<\/p>\n

Saring cairan aluminium pada jalur pengecoran aluminium menggunakan pelat saring, kemudian gunakan penyaringan tabung untuk menyaringnya.<\/p>\n

Filter Busa Keramik Nordic termasuk dalam bidang teknologi pengolahan aluminium cair, khususnya sebagai salah satu jenis penyaringan aluminium cair.<\/p>\n

\"Filter<\/p>\n

Uraian tentang Teknologi Terkait Ketika aluminium dilelehkan menjadi aluminium cair, di dalamnya terdapat pengotor logam lain.
\nKarena aluminium memiliki kepadatan yang lebih rendah daripada kebanyakan logam, strukturnya menjadi lunak dan ringan, serta udara lebih mudah tercampur ke dalam aluminium cair dibandingkan dengan coran logam lainnya, yang menyebabkan terbentuknya cacat pori pada coran tersebut, sehingga memengaruhi kegunaannya dan membuat coran tersebut menjadi limbah.
\nSelain itu, saat menyaring kotoran dalam cairan aluminium yang ada, lubang-lubang saringan pada permukaan pelat saringan mudah tersumbat oleh kotoran, sehingga menurunkan efisiensi penyaringan; dan setelah kotoran tersaring, metode pengangkatan pelat saringan yang ada dilakukan secara manual, yang berisiko menyebabkan cedera pada pekerja di lingkungan bersuhu tinggi.<\/p>\n

Metode penyaringan dan pemurnian cairan aluminium<\/strong>
\nPenggunaan Filter Busa Keramik Nordic merupakan metode paling efektif untuk menghilangkan inklusi dalam lelehan aluminium.
\nSedangkan untuk filter logam dan filter kain serat, keduanya hanya dapat menghilangkan inklusi berukuran besar dalam lelehan paduan aluminium, namun inklusi di bawah tingkat mikron tidak dapat dihilangkan, dan filter logam juga akan mencemari paduan aluminium tersebut.
\nPenggunaan pelat filter keramik berbusa dapat menyaring inklusi-inklusi kecil serta secara signifikan meningkatkan sifat mekanis dan kualitas penampilan hasil coran. Pelat ini merupakan pilihan utama bagi bengkel pengecoran logam cair.<\/p>\n

Prinsip penyaringan<\/strong>
\nYang pelat filter keramik berbusa<\/a> memiliki jaringan berlapis-lapis dan lubang tembus multidimensi, serta lubang-lubang tersebut saling terhubung satu sama lain.
\nSaat proses penyaringan, cairan aluminium membawa inklusi-inklusi tersebut melalui saluran-saluran berliku dan pori-pori, lalu langsung ditangkap, diserap, dan diendapkan saat bersentuhan dengan kerangka berbusa pada pelat saring.
\nKetika logam cair mengalir ke dalam lubang, saluran pada pelat saring berbentuk melengkung, sehingga logam cair yang mengalir melalui saluran tersebut mengubah arah alirannya, dan inklusi-inklusi tersebut bertabrakan dengan anvil dinding lubang dan menempel erat pada dinding lubang.<\/p>\n

Inklusi terak<\/strong>
\nPembentukan inklusi dalam paduan aluminium. Sebagian inklusi dalam paduan aluminium berasal langsung dari limbah logam, sedangkan sebagian besar terbentuk selama proses peleburan dan penuangan, terutama inklusi oksida.<\/p>\n

Semua inklusi yang terbentuk sebelum proses pengecoran disebut inklusi oksidasi primer, yang dapat dibedakan menjadi dua jenis berdasarkan ukurannya
\n1. Inklusi berukuran besar yang tersebar tidak merata dalam makrostruktur menyebabkan struktur paduan menjadi tidak kontinu, mengurangi kepadatan coran, menjadi penyebab korosi dan sumber retakan, sehingga secara signifikan menurunkan kekuatan dan plastisitas paduan.
\n2. Inklusi yang tersebar halus, yang tidak dapat dihilangkan sepenuhnya setelah proses pemurnian. Hal ini meningkatkan viskositas cairan logam dan mengurangi kemampuan aluminium untuk menyusut selama proses pembekuan.<\/p>\n

Inklusi oksidasi sekunder sebagian besar terbentuk selama proses pengecoran. Selama pengecoran, cairan aluminium bersentuhan dengan udara, sehingga oksigen dan aluminium membentuk inklusi teroksidasi.
\nSelama proses peleburan, paduan aluminium bersentuhan dengan berbagai komponen dalam gas tungku sehingga membentuk senyawa seperti AL\u2082O\u2083.
\nAl\u2082O\u2083 dalam cairan aluminium akan meningkatkan kandungan hidrogen pada logam cair paduan aluminium, sehingga kandungan Al\u2082O\u2083 dalam cairan aluminium memiliki pengaruh yang besar terhadap pembentukan pori-pori pada coran aluminium.<\/p>","protected":false},"excerpt":{"rendered":"
