Nozel untuk pengecoran dan penggulungan<\/strong><\/p>\n

Nozel pengecoran dan penggulungan semuanya telah dikalsinasi pada suhu tinggi dan tidak mengandung bahan organik. Tingkat penyusutan pada suhu 800 \u00b0C adalah nol, sehingga dapat digunakan pada berbagai mesin pengecoran kontinu dua rol. Nozel pengecoran lunak yang terbuat dari serat keramik tanpa bola terak, digunakan untuk produksi lembaran aluminium dan foil aluminium sebagai bahan kemasan obat-obatan dan makanan. Nozel pengecoran keras yang terbuat dari serat keramik tanpa bola terak dan bahan pengisi impor memiliki karakteristik kekuatan tinggi, permukaan halus, dan ketahanan aus, serta cocok untuk pengecoran dan penggulungan lembaran aluminium berkecepatan tinggi.<\/p>\n

\"Nozel<\/p>\n

Nozel untuk proses pengecoran dan penggulungan terbuat dari bahan berkualitas tinggi (kecuali natrium silikat), memiliki sifat anti lengket yang baik pada aluminium, konduktivitas termal rendah, stabilitas suhu tinggi, kepadatan yang seragam, permukaan yang halus, serta ukuran yang presisi. Tingkat.<\/p>\n

Tonjolan berbentuk strip yang muncul di sepanjang permukaan produk aluminium merupakan cacat permukaan pada bahan aluminium. Di sisi produk terdapat tonjolan satu sisi, sedangkan di kedua sisinya terdapat tonjolan dua sisi. Beberapa di antaranya terdapat di seluruh bagian produk, namun juga secara lokal, terputus-putus, atau berkala. Tonjolan yang muncul pada permukaan produk harus dihilangkan.<\/p>\n

\"\" \"\"<\/p>\n

Nozel untuk pengecoran dan penggulungan<\/a> terjadinya retakan pada bagian telinga karena logam terisi berlebih di dalam lubang yang telah jadi selama proses penggulungan, sehingga logam berlebih tersebut tertekan masuk ke celah antara rol. Alasan-alasannya antara lain:
\n(1) Desain lubang yang tidak tepat, penyetelan mesin penggiling yang tidak tepat, atau keausan parah pada lubang pada produk jadi, yang mengakibatkan banyaknya lubang pada produk jadi, sehingga menimbulkan tonjolan di kedua sisi;
\n(2) Panduan lubang masuk pada lubang yang sudah jadi tidak terpasang dengan benar, tidak kencang, celahnya terlalu lebar, atau jenis lubang masuknya tidak mudah menyebabkan terbentuknya tonjolan satu sisi atau tonjolan dua sisi yang tidak merata;
\n(3) Suhu bagian yang digulung rendah atau selisih suhu sepanjang seluruh panjangnya besar;
\n(4) Penyesuaian yang kurang tepat pada mesin penggilingan kontinu.
\n(5) Logam dipotong pada lubang bagian depan produk jadi, dan muncul cangkang cembung pada permukaan potongan yang digulung, serta terbentuk tonjolan periodik saat proses penggulungan dilakukan.<\/p>\n

Metode pencegahan dan pemberantasan tersebut adalah:
\n(1) Pilih faktor lebar yang sesuai dan sempurnakan desain lubang;
\n(2) Memperkuat proses penyesuaian pada mesin penggilingan dan mendistribusikan pengurangan secara proporsional;
\n(3) pasang dengan benar pemandu saluran masuk yang sudah jadi;
\n(4) Ganti alur yang sudah aus akibat keausan parah;
\n(5) Meningkatkan kualitas pemanasan billet dan mencapai suhu yang seragam.<\/p>","protected":false},"excerpt":{"rendered":"
