Pengendalian mutu paduan aluminium sangat penting dalam proses peleburan aluminium. Peleburan dan penuangan paduan aluminium merupakan tahap utama dalam produksi pengecoran. Pengendalian yang ketat terhadap seluruh proses peleburan dan pengecoran berperan penting dalam mencegah cacat pengecoran seperti lubang jarum, inklusi, pengecoran yang kurang, retakan, pori-pori, dan porositas penyusutan. Karena kecenderungan penyerapan hidrogen yang tinggi, kemampuan oksidasi yang kuat, dan kemudahan pelarutan besi, langkah-langkah pencegahan yang sederhana dan hati-hati harus diambil dalam proses peleburan dan pengecoran untuk menghasilkan coran berkualitas tinggi.<\/p>\n

\"Pengendalian<\/p>\n

Pengendalian Mutu Paduan Aluminium<\/h2>\n

Untuk menghasilkan lelehan aluminium berkualitas tinggi, bahan baku yang memenuhi syarat harus dipilih terlebih dahulu. Bahan baku harus dikelola secara ilmiah dan diolah dengan benar; jika tidak, kualitas paduan akan sangat terpengaruh. Praktik produksi telah membuktikan bahwa jika bahan baku (termasuk bahan logam dan bahan pembantu) tidak dikendalikan secara ketat, hasil coran akan dibuang secara massal.<\/p>\n

Bahan baku harus memiliki komposisi kimia dan struktur yang memenuhi syarat, dan persyaratan spesifiknya adalah sebagai berikut:<\/p>\n

Selain analisis komponen utama dan kandungan pengotor, mikrostruktur serta permukaan patahan dari ingot paduan yang masuk ke pabrik juga diperiksa. Telah terbukti dalam praktik bahwa sulit untuk memperoleh coran yang padat dengan menggunakan aluminium cair yang mengandung penyusutan parah, lubang jarum, dan gelembung, dan bahkan seluruh isi tungku serta seluruh batch coran tersebut akan dibuang.<\/p>\n

Telah ditemukan bahwa tidak terdapat lubang jarum pada blok uji cetakan pasir cor murni ketika ingot paduan aluminium-silikon cair digunakan untuk meneliti pengaruh ingot paduan aluminium-silikon terhadap terjadinya lubang jarum pada paduan aluminium.<\/p>\n

\"Pengendalian<\/p>\n

Ketika ditambahkan ingot paduan aluminium-silikon dengan struktur rendah dan kualitas tidak memadai, lubang jarum pada blok uji menjadi parah dan ukuran butirnya besar. Penyebabnya adalah sifat warisan material tersebut. Sifat warisan paduan Al-Si meningkat seiring dengan meningkatnya kandungan Si. Ketika kandungan Si mencapai 7%, sifat warisan tersebut menjadi jelas. Kecenderungan tersebut sedikit menurun seiring dengan meningkatnya kandungan silikon hingga mencapai komposisi eutektik. Untuk mengatasi cacat pengecoran yang disebabkan oleh kecenderungan bahan baku, perlu dilakukan pemilihan ingot aluminium,\u00a0bahan tambahan paduan logam<\/a>, serta bahan baku lainnya yang memiliki kualitas metalurgi tinggi.<\/p>","protected":false},"excerpt":{"rendered":"
