    • PURPOSE:To improve the sheet-thickness accuracy of a product by pressing separately rotating sectional-rolls against a rotating rolling-roll and calculating the diam. difference of rolling roll and the number of revolutions of sectional rolls. CONSTITUTION:As a sectional roll, the outer ring 41 of an outer-ring rotating type bearing 4 is used. Bearings 401-403 are arranged on an axis 6 as the sectional rolls, and sensors 5 for measuring the number of revolutions are provided to the bearings respectively. When the fixed bearings 9 of axis 6 are pressed against a rolling roll 2 through a pressing device 10; the axis 6 is easily deflected because of its slenderness, and all of the bearings 401-403 come into contact with the roll 2 and rotate. The diameter difference of roll 2 is easily obtained by using a prescribed calculating equation based on the measured number of revolutions N1 and N2 of the bearings 401-402. Accordingly, the distribution of gap in the axial direction of roll 2 can be controlled, and the sheet-thickness accuracy of a product is improved.

    • PURPOSE:To perform on-line measuring operation by measuring the distance to the surface of a roll by main ultrasonic range finders of water column structure arranged in parallel to a roll shaft and measuring the distance to a reference wire parallel to the roll shaft by subordinate ultrasonic range finders, and correcting the position of a reference surface. CONSTITUTION:Plural main ultrasonic range finders 18 of water structure are fixed on the reference surface 14 of a reference rack 13 in parallel to the shaft of the roll 11, the reference wire 16 is extended in the water filled chamber 15 of the rack 13 in parallel to the shaft of the roll 11, and subordinate ultrasonic range finders 20 are fixed in back-surface side chambers 15 of the respective range finders 18. In this case, the range finders 20 measure the distance from the surface 14 to the wire while not displaced at right angles to the shaft of the roll 11 relatively with the respective range finders 18 and the distance between the surface 14 and the surface of the roll 11 which is obtained by the range finder 18 is corrected with outputs of the range finders 20. Consequently, even when the rack 13 deforms, the profile is measured accurately.

    • PURPOSE:To improve the measuring accuracy by providing an oscillator to the inside of an ultrasonic probe head of water column construction as well as disposing a reference reflector, used for reflecting and passing the pulse energy, between the vibrator and the surface of roll. CONSTITUTION:A probe head 11 is equipped with a nozzle 12 as well as provided with a vibrator 13 used for transmitting and receiving an ultrasonic wave. A reference reflector 15 for reflecting and passing a part of the pulse energy of ultrasonic wave, is disposed in the inside of nozzle 12. The vibrator 13 is excited through a pulser 17 while synchronizing with a main pulse generator 16, and a receiver 18 receives and amplifys an exciting pulse and a reflected pulse reflected from the reflector 15 and the roll surface 14. Next, a roll profile is accurately computed from an underwater pulse speed, corrected in the effect of temperature, through delay pulse generators 19, 20. In this way, the measuring accuracy is improved in on-line.
