Abstract
A method for setting a rolling mill, the method being executed before reduction position zero point adjustment or before the start of rolling, and including: a first process of setting rolls in an open state, and with respect to each of the upper roll assembly and the lower roll assembly, adjusting positions of roll chocks in a rolling direction based on a torque acting on the work roll or a vertical roll load difference; and a second process of, after the first process, setting rolls in a kiss roll state, measuring a vertical roll load in two rotational states on a work side and a drive side, and moving roll chocks of a roll assembly on the opposite side to a reference roll simultaneously and in a same direction so that the vertical roll load difference falls within an allowable range to thereby adjust the positions of the roll chocks.
