<p>PROBLEM TO BE SOLVED: To prevent abnormal dimension by taking thickness and width based on a specified equation as the target rolling size when estimated rolled length by weighing from the specified equation based on expected rolling quantity and weight difference rate is over a predetermined set length. SOLUTION: When the reduced rolled length La by weighing determined by a specified equation I based on the expected rolled length Lo and weight difference rate X is over the preset length, the thickness Hr and width Wr are determined by the specified equations II, III based on the reduced rolled length La by weighing, target thickness Ho and target width Wo. In the case that the reduced rolled length La by weighing is within the preset set length, the length margin rate Aa of the steel plate is determined by the specified equations based on the yield P of rolled length and the weight difference rate X and, when this rate is less than a preset reference range, the thickness Hr is determined based on the target thickness Ho. When the length margin rateαis not less than the preset reference range, by determining the thickness Hr and width Wr based on the target thickness Ho and the target width Wo, abnormal dimension is prevented. Where, K1, K2 are adjusting coefficients.</p> |
