Abstract

PURPOSE:To control a rolling position so as to prevent a material to be rolled from the increase of a curve and an off-center, by respectively calculating the difference of the sheet thicknesses between that of the left and right sides of the material at the exit of a preceding pass and a succeeding pass, made as a controlling object, in a rolling mill, and comparing the calculated standard value of the difference of reactions between that of the left and right sides with that of the actually detected values to adjust roll gaps at the left and right sides of a roll at the succeeding pass. CONSTITUTION:A standard value setting device 20 calculates the sheet thicknesses at the left and right sides of the exit to a preceding stand 11 basing on a set value of the roll gap difference between that of the left and right sides, etc. Next, the device 20 calculates the sheet thickness at the exit side which prevents the increase of a curve and a quantity of off-center at a succeeding stand 12 made as a controlling object. Next, the device 20 calculates a standard value of the difference between the rolling reactions. A transverse deflection controlling device 19 compares the detected value of the difference between left and right rolling reactions, basing on the detected results detected by left and right rolling load meters 16A, 16B provided to the stand 12, with the standard value of the difference between the rolling reactions calculated by the device 20, and transmits a command of the roll gap difference between that of the left and right sides to a rolling reduction controlling device 18 so as to make the detected value coincide with the calculated standard value.
