<P>PROBLEM TO BE SOLVED: To provide a measuring device with which the plate width of a rolled plate material is measured with high accuracy. <P>SOLUTION: A measuring device 1 is provided for measuring the plate width of the rolled plate material 101 which is inserted into a hot rolling line advanced on an advancing route. A pair of measuring members 40 which are situated on both sides across the advancing route are engaged with a single slide rail 3 which is provided below a supporting plate and laid so as to extend vertically to the advancing route. A first and a second servomotor unit 50 for moving the measuring members are situated on both sides of the measuring members. Each rotation of them is controlled by a controller and, meanwhile, each current value corresponding to rotational torque is detected. In this place, the controller 60 make the rotation of the corresponding servomotor unit stop. A pair of measuring members more approachably by driving the servomotor unit, make the rotation of the corresponding servomotor unit stop on the basis of a current value which is changed by bringing into contact with one side end of the rolled plate material and the relative position to the slide rail of the side end is determined. The plate width is measured from the relative positions of the two servomotor unit. <P>COPYRIGHT: (C)2013,JPO&INPIT |
