ANALYSIS OF ROLL SYSTEM STABI-LITY ABOUT ALUMINUM FOIL MILLS*
Abstract: To improve roll system stability of aluminum foil mills, roll system stability of 2200 high-speed aluminum foil mill is analyzed with energy stable method. Two different restrictive conditions which gaps between chock of work roll and window of stand whether exist or not, are studied respectively. A new concept of roll system with open /closed compound pair comes up with as well for renewably synthesizing restrictive mechanism of aluminum foil mills’ chock. Through these studies, the conflict, whether reserving the gap for the roller replacement or eliminating the gap for roller’s normal work, is successfully settled. This concept and analyzed result give the actual mechanism with open/closed compound restriction and the method of realizing high-speed rolling and prolonging longevity of end thrust bearing on work roll. It has important theoretical meaning and engineering value for modern technical reform of aluminum foil mills and plate strip mills.
