Benda kerja yang dihasilkan melalui proses pengecoran cetakan paduan aluminium sering kali harus dibuang karena adanya pori-pori. Ada banyak penyebab terjadinya cacat pori pada pengecoran aluminium. Saat mengatasi masalah kualitas produk ini, seringkali sulit untuk memulai. Bagaimana cara mengambil langkah-langkah dengan cepat dan tepat untuk mengurangi tingkat limbah yang disebabkan oleh pori-pori tersebut? Inilah masalah yang menjadi perhatian para produsen pengecoran logam paduan aluminium.<\/p>\n

Dalam proses produksi pengecoran cetakan paduan aluminium, terdapat banyak faktor yang menyebabkan munculnya porositas pada produk, dan masalah ini harus diatasi dengan mengidentifikasi penyebabnya serta menangani akar masalahnya.<\/p>\n

\"Cacat<\/p>\n

Langkah-langkah untuk Mencegah Cacat Poros pada Coran Aluminium<\/h2>\n

(1) Pastikan kualitas penghilangan gas pada proses peleburan paduan aluminium. Pilihlah yang berkualitas baik zat pemurnian<\/a> serta unit penghilang gas untuk mengurangi kandungan gas dalam cairan aluminium, serta menghilangkan endapan di permukaan cairan dan oksida secara tepat waktu guna mencegah gas tersebut terbawa kembali ke dalam proses pengecoran cetakan.<\/p>\n

(2) Pilihlah bahan pelepas cetakan yang baik. Bahan pelepas cetakan yang dipilih tidak boleh menghasilkan gas selama proses pengecoran cetakan dan harus memiliki kinerja pelepasan cetakan yang baik.<\/p>\n

(3) Pastikan saluran pembuangan pada cetakan tidak tersumbat, alirannya lancar, dan gas di dalam cetakan telah sepenuhnya dikeluarkan; terutama saluran pembuangan di titik polimerisasi akhir cairan aluminium harus bebas dari penyumbatan.<\/p>\n

(4) Sesuaikan parameter pengecoran cetakan, dan kecepatan pengisian sebaiknya tidak terlalu cepat untuk mencegah terbentuknya gas. Suhu pengecoran juga harus dikendalikan dengan baik.<\/p>\n

(5) Perlu diperhatikan penerapan teknik penarikan inti dan pendinginan dalam desain produk dan desain cetakan guna meminimalkan perbedaan ketebalan dinding yang berlebihan.<\/p>\n

(6) Lubang-lubang udara yang sering muncul pada bagian-bagian tetap perlu diperbaiki dari segi cetakan dan desain.<\/p>","protected":false},"excerpt":{"rendered":"
