Geçiş işleme hızının seçim ilkesi aşağıdaki gibidir:
(1) Ekipman kapasitesinin haddeleme yağının iyi yağlama ve soğutma performansına sahip olmasını sağladığı öncülünde, ve iyi yüzey kalitesi ve şekil kalitesi elde edebilir, haddelenmiş metalin plastisitesinden tam olarak yararlanılmalıdır, 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, kalite, production efficiency and other conditions in field practice.
