Abstract
PURPOSE:To measure the lateral bend of a material to be rolled rapidly and quantitatively by obtaining the central position of said material by the width detecting means provided just near the outlet side of rolling rolls and on the lower stream by a prescribed distance from the outlet side. CONSTITUTION:The central position of a material 20 to be rolled is obtained as a rate of deviation from the centerline B of a rolling roll 22 with the 1st central position operator 28 by using the distances S11, S12 from both side faces of the material 20 measured with the rangefinders 24a, 24b disposed just near the outlet side of the roll 22. Similarly, a similar rate of deviation is obtained with the 2nd central position operator 30 by using the outputs S21, S22 of the rangefinders 26a, 26b in the positions away by l0 from the roll 22. Also, the distance from the leading end of the material 20 is inputted to a lateral bend operator 34 via a mill motor 23 and a pulse generator 32. The operator 34 calculates a rate of side bend by using the above-mentioned two rates of deviation and the distance from the leading end of the material 20, and has it recorded in a recorder 36 and an X-Y recorder 38.
