Lub hauv paus ntsiab lus xaiv ntawm kev ua tiav tus nqi yog raws li hauv qab no:
(1) Raws li qhov tseeb hais tias cov cuab yeej muaj peev xwm tso cai rau cov roj dov kom muaj lubrication zoo thiab ua haujlwm txias, thiab tuaj yeem tau txais qhov zoo ntawm qhov zoo thiab cov duab zoo, lub plasticity ntawm cov dov hlau yuav tsum tau siv tag nrho, and the large pass processing rate should be used as much as possible to improve the rolling mill Production efficiency.
(2) Pass processing rate, fully consider the performance of the rolling mill, process lubrication, tension, original roll shape, and rolling speed. The rolling pass processing rate of the original or semi-hard aluminum foil blank is generally 40%-65%, and the rolling pass processing rate of the hard aluminum foil blank is generally 20%-40%.
(3) For products with high requirements for thickness deviation, surface quality, and shape quality, a smaller pass processing rate should be selected.
(4) For rolling mills with automatic thickness control system and strip shape automatic control system, a larger pass processing rate can be appropriately adopted.
(5) The selection of pass processing rate should be based on the actual situation, and finally determined after continuous exploration and summary based on equipment, quality, production efficiency and other conditions in field practice.
