Ing produksi foil pindho, rolling saka aluminium foil dipérang dadi telung pangolahan: rolling kasar, rolling penengah, lan rampung rolling. Saka sudut pandang teknologi, bisa kira-kira dipérang saka kekandelan metu rolling. Cara umum yaiku yen kekandelan metu luwih gedhe tinimbang Utawa padha karo 0.05mm yaiku rolling kasar, kekandelan metu antarane 0.013 lan 0.05 punika rolling penengah, and the single finished product and the double rolled product with the exit thickness less than 0.013mm are finished rolling. Karakteristik rolling kasar padha karo karakteristik rolling saka piring aluminium lan Strip. Kontrol kekandelan utamané gumantung ing pasukan rolling lan post tension. Kekandelan saka rolling atos cilik banget, lan karakteristik rolling temen beda saka rolling saka piring aluminium lan Strip. Wis aluminium foil rolling. Kekhususan saka, ciri utamane kalebu aspek ing ngisor iki:
(1) Aluminium strip rolling. Kanggo nggawe strip aluminium tipis utamané gumantung ing pasukan rolling, supaya cara kontrol kekandelan otomatis punika longkangan muter pancet minangka cara kontrol utama saka AGC. Malah yen pasukan muter ganti, longkangan muter bisa diatur ing sembarang wektu supaya longkangan muter ing Nilai tartamtu diwenehi kekandelan. Plat lan Strip sing konsisten. Nalika aluminium foil wis mbalek kanggo medium-rampung rolling, amarga kekandelan saka aluminium foil arang banget lancip, pasukan rolling tambah sak rolling, kang nggampangake kanggo muter kanggo gawé ewah-ewahan bentuk elastis saka materi kang mbalek. Flattening elastis saka gulungan ora bisa. ora digatekake, rolling lentur lan flattening saka nggulung nemtokake sing ing aluminium foil rolling, pasukan rolling bisa maneh muter peran padha karo piring mbalek. Aluminium foil rolling umume muter-free rolling ing kahanan meksa pancet kanggo nyetel kekandelan saka aluminium foil.. Utamane gumantung saka tension sing disetel lan kacepetan muter.
(2) Tumpukan rolling. Kanggo aluminium foil ultra-tipis kanthi kekandelan kurang saka 0,012mm (kekandelan related kanggo diameteripun saka muter karya), amarga flattening elastis saka gulungan, iku banget angel kanggo nggunakake cara rolling single-sheet, so the double rolling method is used, iku, the The method of adding lubricating oil between two aluminum foils and then rolling them together (uga disebut tumpukan rolling). Stack rolling ora mung bisa ngasilake aluminium foil ultra-tipis sing ora bisa diprodhuksi dening rolling siji, but also reduce the number of strip breaks and increase labor productivity. Nggunakake proses iki, aluminium foil mulus siji-sisi 0,006mm nganti 0,03mm bisa diproduksi massal.
(3) Efek kacepetan. Ing proses rolling aluminium foil, kedadean sing kekandelan saka foil thins karo munggah saka sistem rolling diarani efek kacepetan. The explanation of the speed effect mechanism still needs to be studied in depth. The reasons for the speed effect are generally considered to have the following three aspects:
1) Negara gesekan antarane gulungan karya lan owah-owahan materi sing digulung. Minangka kacepetan rolling mundhak, jumlah lenga lubricating ngenalaken mundhak, supaya negara lubrication antarane muter lan owah-owahan materi mbalek. Koefisien gesekan mudhun, film lenga dadi luwih kenthel, and the thickness of the aluminum foil decreases accordingly.
2) Owah-owahan ing gilingan rolling dhewe. In a rolling mill with cylindrical bearings, minangka kacepetan rolling mundhak, the roll neck will float in the bearing, so that the two interacting and loaded rolls will move toward each other.
3) The processing softens when the material is deformed by rolling. Kacepetan rolling saka pabrik rolling aluminium foil kacepetan dhuwur banget. Minangka kacepetan rolling mundhak, suhu zona deformasi rolling mundhak. Miturut petungan, suhu logam ing zona deformasi bisa munggah kanggo 200 ° C, kang padha karo annealing Recovery penengah. Fenomena softening pangolahan bahan sing digulung.
