Abstract

PURPOSE:To control snaking effectively by providing four pieces of roll cells between an upper backup roll chock and the upper part of a housing and between a lower backup roll chock and the lower part of the housing on the work side and the driving side. CONSTITUTION:A rolled material S is rolled down with work rolls 3, 4. The load to be applied on backup rolls 1, 2 with screws is detected with vertical and lateral load detectors 8, 8', 9, 9' and are fed to a calculator, by which the differential rate of load is determined. The result of the calculation is inputted to a proportional calculator 11 and a differential calculator 12. The proportional action signal and differential action signal from these calculators are added in an adder 13. The signal from the adder 13 is fed through a rolling position controller 14 to lateral rolling position setters 7, 7', by which the roll gap on the right and left is adjusted according to the rate of snaking.
