Pengecoran Bush<\/strong> merupakan salah satu bagian yang paling penting sebelum aluminium cair masuk ke dalam cetakan.
\nPengecoran hot-top merujuk pada metode pengecoran di mana terdapat bagian dengan kinerja retensi panas yang baik di bagian atas cetakan, yang digunakan untuk memperlambat pendinginan awal pada bagian atas cetakan, bukan untuk memperlambat pendinginan awal seluruh cetakan.<\/p>\n

Pengecoran ingot dengan bagian atas panas mengacu pada<\/strong> terkait proses pengecoran ingot semi-kontinu paduan aluminium dengan menggunakan cetakan yang dilengkapi lapisan isolasi termal pada bagian atasnya.
\nProses pengecoran ingot ini biasanya dilakukan dengan memasang tangki penyimpanan cairan yang terbuat dari bahan isolasi panas tahan api pada bagian atas cetakan ingot semi-kontinu dari paduan aluminium, atau dengan melapisi secara merata bagian atas permukaan dalam cetakan biasa dengan lapisan isolasi panas fleksibel. Zonaterbuat dari bahan isolasi panas, yang berfungsi untuk menjaga logam cair pada suhu yang lebih tinggi saat memasuki bagian cetakan melalui corong.<\/p>\n

\"Pemilihan<\/p>\n

Proses pengecoran Bush merupakan salah satu bagian terpenting dari platform pengecoran hot top.<\/strong>
\nCetakan untuk pengecoran ingot dengan sistem hot top terdiri dari bagian hot top yang dilengkapi isolasi panas dan bagian tanpa isolasi yang berfungsi untuk memadatkan dan mengkristalkan logam cair.
\nBagian atas yang panas tidak hanya menjaga agar logam cair tetap hangat, tetapi juga selalu mempertahankan kolom cair di bagian atas ingot, sehingga memberikan tekanan statis tertentu pada logam cair yang akan mengeras dan mengkristal, sekaligus menurunkan posisi pengerasannya di dalam kristalisator.
\nTinggi bagian kristal yang telah mengeras umumnya berkisar antara 20\u201350 mm, yang berfungsi untuk mengkristalkan dan membentuk lelehan.
\nPenggunaan metode pengecoran ingot hot top dapat mewujudkan proses pengecoran ingot dengan kristalisator pendek yang stabil serta mencapai tingkat teknologi pengecoran ingot yang setara, yaitu dengan menghilangkan corong, dan pemindahan logam cair dilakukan melalui metode penyaluran cairan secara horizontal, sehingga kualitas dan efisiensi produksi ingot pun meningkat.
\nIngot hot top memiliki struktur yang seragam, sifat mekanis yang baik, permukaan yang halus, tingkat segregasi yang lebih rendah, serta mengurangi jumlah serpihan hasil penggilingan dan kehilangan logam. Di sisi lain, metode pengecoran ingot hot top menyederhanakan proses produksi dan meningkatkan kondisi kerja.<\/p>","protected":false},"excerpt":{"rendered":"
