Abstract

PURPOSE:To control a roll opening with high accuracy and raise the level of plate width control by detecting the opening by detecting each absolute position of contact part of rolled stock of left and right vertical rolls. CONSTITUTION:A roll profile arithmetic device operates the difference between detected values l21, l22 of the second detectors 47, 48 and detected values l31, l32 of the third detectors 49, 50. This operated value indicates the change of roll profile of contact part of rolled stock of vertical rolls 14, 15 due to wear of roll and thermal expansion. A roll opening arithmetic device operates the true roll opening from preset distances L1, L2, l0, diameters d1, d2, detected values l11, l12, inputted from the first detectors 41, 42, detected values l31, l32 inputted from the third detectors 49, 50 and the operated value inputted from the roll profile arithmetic device. Accordingly, errors in detection of roll opening due to elastic deformation of a edger housing 11, compressive elastic deformation of vertical roll chocks 12, 13 etc., deflection of vertical rolls 14, 15 etc. are eliminated perfectly.
