【Abstract】 The electric APC control system was applied to realize the automatic control of roll gap of screw down. The composition and realization method of APC system were introduced. The size of different plate was better controlled because the location precision was improved after using APC. Meanwhile,the negative rolling technology and plate quality were assured.更多还原
