<p>PURPOSE:To reduce the variance of rolling accuracy due to partitioned straddle by regarding the division of a target rolled load of an object material to be rolled as the weighted mean of the division of a rolled load corresponding to each group by the weight of fidelty of each group. CONSTITUTION:When a preparation for a passing strip is indicated, a fuzzy expression converter 10 converts information of rolled stock inputted by a input device 9 into the fidelty of each group and a draft schedule calculating device calculates a draft schedule. A gap to be set to each rolling mill based on the draft schedule is calculated by a draft clearance calculating device 8 and rolling mill clearance setting devices 11-1 - 11-7 set the nips. Rolling is begun and detector 3-1 - 3-7 give rolling load detected values to an actual load balance calculating devicde 4. The device 4 calculates the actual load balances and gives them to a model coefficient updating device 5. The updating device 5 calculates coefficient vectors and calculation data and updates and writes them to a memory 6.</p> |
