Abstract:
A method of adjusting a roll position in a bar steel rolling mill, comprising:(a) illuminating a caliber of a roll;(b) inputting video signals of sensing positions of the roll caliber located at portions of the roll caliber located approximately symmetrically with respect to a rolling reduction direction of the roll;(c) determining actually measured profiles of the sensing positions based on the video signals; and(d) determining a first guidance in the rolling reduction direction from the sum of the areas located between the actually measured profiles and the reference profiles at the sensing positions;(e) determining a second guidance in the roll axial direction from the difference between the areas located between the actually measured profiles and the reference profiles at the sensing positions; and(f) adjusting the roll position in the rolling reduction direction and the roll axial direction based on the first guidance and the second guidance, respectively.
