<p>PURPOSE: To easily and surely determine an apropreate pass schedule for utilizing equipment performance at the maximum. CONSTITUTION: In a hot finishing mill for rolling a sheet bar after rough rolling, constraint conditions and other rolling conditions from the viewpoint of equipment and operation and the target thickness, width, rolling temp. and rolling speed on the outlet side of the 7th (final) stand are set to each stand (step 110), the retroactive calculation of the max. thickness and rolling temp. which are rolled in each stand in the range of the constraint conditions is successively executed using each target value from the final stand according to the steps 112-134. The max. thickness of the sheet bar which can be rolled in the 1st stand is determined (step 136) and, defining the max. thickness and rolling temp. which are attained in every stand as a guide line, actual pass schedule is determined in that range.</p> |
