Abstract

PURPOSE:To measure the deflection of a working roll simply and accurately by inserting a bar provided with plural strain gauges into a hollow part provided along the axis of the roll and operating the deflection of the bar by signals from strain gauges. CONSTITUTION:A bar 2 having nearly the same length as the body 11 of a roll is inserted into a hollow part provided along the axis of the working roll 1 of a rolling mill. Plural, for instance five, strain gauges 3A, 3B, 3C, 3D, 3E are burried at suitable interval along longitudinal direction. A signal sending device 5 that inputs signals obtained from the strain gauges 3 is provided in the hollow part 10 and connected to an external arithmetic device 4. By this, signals from the strain gauges 3 are inputted to the arithmetic device 4 through the signal sending device 5 and deflection deformation and the amount of deflection of the bar as a whole are operated. Since the bar 2 is structured in a body with the working roll 1, the amount of deflection of the working roll itself can be determined.
