摘要： PROBLEM TO BE SOLVED: To easily and accurately detect the tension given to a belt-like material. SOLUTION: A tension detecting device is provided with a rotary sleeve 4 which is rotatably supported on the outer periphery of a fixed shaft 3 with pressurized air in between and rotates when the sleeve 4 comes into contact with a strip 2, a gap sensor which detects the amount of the gap between the shaft 3 and sleeve 4 at a part facing the strip 2, a pressure sensor 9 which detects the pressure in the gap, and an arithmetic means which computes the tension of the strip 2 based on the detected results of the sensors 8 and 9. The detecting device easily and accurately detects the tension given to the strip 2 by finding the tension of the strip 2 by detecting the state of the gap between the sleeve 4 and shaft 3 by means of the sensors 8 and 9 and analyzing the detected amount of the gap and pressure in the gap by means of the arithmetic means.

摘要： PURPOSE:To accurately measure tensions between stands by comparing a loaded value of a loading device and a detected value from a load detector with a mill stand combined with two calibration work roll stands. CONSTITUTION:With a mill stand of a rolling mill combined with a measuring roll stand 20 and a dummy roll stand 21, a loading device 22 between the stands 20 and 21 is actuated by a hydraulic pump 23 to load the stand 20 with a tension or a compression force in the rolling direction. In that time, a load detector 17 installed between the mill stand and the stand 20 measures loads in the rolling direction acting on the stand 20 and compares a loaded value of the device 22 and a detected value by the detector 17. In this method, a measuring accuracy of the entire load detecting mechanism is verified, so that a tension between stands is measured accurately.

摘要： PURPOSE:To detect push and pull force with a simple signal process and good accuracy by detecting the torque when a material engages with one roll of a vertical type horizontal mill, detecting the max. value of the torque when the material engages with both rolls in succession thereto and detecting the push and pull force from the difference between both detected torques. CONSTITUTION:A push and pull force detector 8 detects the torque with a torque detector 6 upon receipt of a signal 12 for the engagement of the material with the vertical roll 3, stores the torque Tv by the rolling with the roll 3 into memory 13 and inputs the signal thereof into an arithmetic unit 14. The detector detects the torque by the simultaneous engagement of the material with the roll 3 and a horizontal roll 1 upon receipt of a signal 15 for the engagement of the material with the roll 1, stores the max. value Tmax. thereof into a memory 16 and inputs the signal thereof to the unit 4. The push and pull force 9 is detected from the difference between the two detected torques Tv, Tmax. by the signals from the memories 13, 16, etc. and is outputted therefrom.

摘要： PURPOSE:To perform highly accurate calibration in a short time, in a tandem rolling mill, by compressing a steel strip by the roll in a front stage stand of a tension meter, fixing the steel strip, releasing the compression by the roll in the rear stage stand, thereby performing the calibration. CONSTITUTION:A tension meter 1, which is provided between a stand Fn and a stand Fn+1 is calibrated. Based on the input of a CAL signal (m) from a control operator 3, a compressing command (r) is outputted so that the compression is applied to the stand Fn, in order to fix a steel strip that is a material to be measured. The command (r) makes a roll Rn to be compressed through a compressing device Sn 5, and the steel strip is fixed. Meanwhile, tensile strength to be applied to the steel strip is applied by a reel motor. The stand Fn+1 is under the released state. The device 3 imparts an input (a) to a tensile strength operator 2 when an error is present between the tensile strength and the output value of the tensile strength of the tension meter 1, and performs the calibration. Therefore, the stopping time of the rolling mill is very short, and the highly accurate calibration can be performed.
