1982年5月洛阳有色金属加工设计研究院受洛阳矿山机器厂的委托,承担了设计现代化铝带冷轧机组(包括剪切机组、退火炉等辅助设备)的任务。六十年代以前,铝带冷轧机多为四辊可逆式,在这种轧机上,每轧完一个道次,必须给定一次辊缝,而且都以不脱卷的方式轧制,带材头尾的切除量大,降低了轧制成品率。为克服上述缺点,国外新型铝带冷轧机几乎都是四辊不可逆式。这种轧机的优点是:(1)减少了辊缝调整次数,提高了辊缝调整精度,每精调一次辊缝后,可成批进行轧制,提高了轧制精
1982 May Luoyang Nonferrous Metals Processing Design and Research Institute commissioned by the Luoyang Mining Machinery Factory, assumed the task of designing modern cold strip mill (including cutting units, annealing furnace and other auxiliary equipment). Before the sixties, aluminum strip cold rolling mill is mostly four-roller reversible, in this rolling mill, each rolling a pass, must be given a roll gap, and are not rolled off the strip, the strip The amount of head and tail resection, reducing the rolling yield. To overcome the above shortcomings, foreign new aluminum strip cold rolling mill almost all four-roller irreversible. The advantages of this type of rolling mill are as follows: (1) The number of roll gap adjustment is reduced and the precision of roll gap adjustment is improved. After the roll gap is finely adjusted, the roll can be rolled in bulk to improve the rolling precision
