<p>PURPOSE:To provide a suitably setting method of the pass schedule of a next material in a shape adjusting pass of a thick plate rolling. CONSTITUTION:A pass schedule is set so that a set value C1 of outlet side plate crown of each pass and a set value h1 of outlet side plate thickness, which are calculated from a target value of outlet side plate crown and a target value of outlet side plate thickness in the final pass of a next material and a plate crown predicting model, and a rolling load predicting model, satisfy the relation not generating shape defects. When the actually measured value of the outlet side plate thickness in the final pass of the preceding material is defined as (a), the actually measured value of the outlet side plate crown in the same pass as (b), and the target value of the outlet side plate crown in the final pass of the next material as (c), the pass schedule of the next material is set so that the outlet side plate crown C1 and the outlet side plate thickness h1 of each pass satisfy the relation of C1=(b/a)Xh1+c-b.</p> |
