摘要

PROBLEM TO BE SOLVED: To control the speed of a pressing roll precisely and by quick response in equipment having the pressing roll using an elastic material like rubber as a lining material used by pressing against a metal strip.;SOLUTION: The speed control device of the pressing roll includes: a press reduction computing means 22 measuring a press reduction L of the pressing roll from a detection distance D etc.; a conveyance distance variation computing means 24 obtaining a variation Y in a conveyance distance of the metal strip per angle of rotation of the pressing roll by the deformation of the roll based on the measured press reduction L and according to variation setting information like a model formula etc.; and a rotating speed command correction means 26 performing correction (N') of a rotating speed command N being a criterion on the basis of the obtained variation Y of the conveyance distance.;COPYRIGHT: (C)2013,JPO&INPIT
