<p>PROBLEM TO BE SOLVED: To provide a method for predicting the quality of materials of steel plates capable of obtaining a high accuracy of materials prediction at a high speed and a method for correcting a pass schedule capable of using the results of the materials prediction. SOLUTION: A method for predicting the quality of materials of hot-rolled steel plates manufactured by repeatedly rolling billet inγsingle-phase area and an aggregate averageγparticle size and an aggregate average residual distortion in all the areas of a re-crystallized section and a raw re-crystallized section obtained after the final pass are found, and based on the data obtained, the quality of materials of steel plates are directly predicted. By separating the re-crystallized section A from the raw re-crystallized section B in the former pass, the computation to find aγsystem of partial re-crystallized construction constituting the re-crystallized section A3 having the averageγparticle size of No.1 re-crystallized section A1 and No.2 re-crystallized section B1 generated from each region A, B and the raw re-crystallized section B3 having the averageγparticle size and the average residual distortion of No.1 raw re-crystallized section A2 and No.2 raw re-crystallized section B2 generated from each region A, B is repeatedly executed until the final pass to find aγcomposition (an averageγparticle size and average residual distortion) after the final pass.</p> |
