Abstract

PURPOSE:To improve accuracy of plate width measurement in a hot strip finishing mill by grasping movement of the looper between stands and compensating the variation of height of the rolled plate and enabling visual measurement of plate width. CONSTITUTION:The movement of a looper 3 that lies between the front stand 1 and rear stand 2 and keeps the tension of a rolled plate 4 constant is detected by a looper angle detector. At the same time, visual angle of the direction of width of the rolled plate is detected by a photoelectric detector 6. The detection signals from above-mentioned detectors are inputted to a computer anf the width of the rolled plate is calculated accurately.
