Abstract

PURPOSE:To obtain a roll rotation measuring device which is excellent in the response properties with high accuracy, by setting a displacement meter at a position close to a signal generating part provided at the edge of rolling mill and analyzing the frequency, etc. of the voltage signal. CONSTITUTION:A displacement meter is set at a position close to a rotary signal generator provided at the edge of the longer side of a rolling mill, and the frequency or the phase of the voltage signal produced from the signal generator is analyzed by an analyzer to perform the measurement of rotations of the roll. For instance,rotary signal generating members 3 and 4 are attached at the edge parts of a backup roll 1 and a work roll 2 respectively. In addition, detection edges 5a and 5b of the displacement meter are set close to the members 3 and 4. The signals of the edges 5a and 6a are fed to a signal analyzer via displacement gauge processing circuits 5b and 6b. Thus the number of rotations of each roll is measured, and the occurrence of a slip is detected. Then the results of these measurements are displayed, and an alarm device is actuated when necessary.
