Abstract
PURPOSE:To uniformize the wear of work rolls and to also uniformize the surface roughness of a steel strip by skin pass rolling a preceding steel strip with the strip moved in the width direction by at least a moving amount being equal to a width difference between the preceding and succeeding strips at the case that the succeeding strip is wider than the preceding strip. CONSTITUTION:At the time of skin pass rolling of steel strips whose width are different, respective moving amounts of respective strips in the width direction are calculated based on a passage schedule of the strips. Then, in passage, a preset computer 6 calculates momentary moving target values based on length measuring pulse signals of a pulse generator 9 and inputs calculated values to a steering controller 5C. The controller 5C actuates a steering device 5A based on signals of a strip position detector 5B so that a steel strip 10 has a moving target value at the outlet side of the steering device 5A. The strip 10 is moved by an amount larger than a width difference in the width direction and is subjected to skin pass rolling. Hence, wear in the width direction of work rolls 1A, 1B is uniformized.
