Title:
圧延機におけるロールギャップを制御する方法
Document Type and Number:
Japanese Patent JP7375189
Kind Code:
B2
Abstract:
There is provided a method of controlling a roll gap between first and second work rolls (102, 104) of a rolling mill, work surfaces (102a) of the first and second work rolls (102, 104) being arranged in opposing relationship and respective longitudinal axes of the rolls (102, 104) lying in a common plane, in use said work surfaces (102a) being spaced apart so as to form the gap for receiving a metallic product for rolling, the method comprising: defining a plurality of work surface locations spaced apart along the first work roll (102) in the longitudinal direction; obtaining a radius of the work surface (102a) of the first work roll (102) at each of the work surface locations; based on the radii of the work surface locations, obtaining a longitudinal profile of the work surface (102a); based on said longitudinal profile, tilting the first work roll (102) relative to the second work roll (104) in the common plane in order to reduce a difference in the average size of the gap either side of a centreline (CL) which bisects the longitudinal axes of the first and second work rolls (102, 104).
