Принципът на избор на скорост на обработка на пропуска е както следва:
(1) При предпоставката, че капацитетът на оборудването позволява на маслото за валцоване да има добро смазване и охлаждане, и може да получи добро качество на повърхността и качество на формата, пластичността на валцувания метал трябва да се използва напълно, 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, качество, production efficiency and other conditions in field practice.
