<p><P>PROBLEM TO BE SOLVED: To provide a rolling method by which the amount of occurrence of defects in size and shape is reduced in the case a preceding steel strip and the succeeding steel strip are considered that they are the same in rolling accompanying flying setting change of a continuous metallic band. <P>SOLUTION: When the ratio (K2/K1) of deformation-resistant values of the preceding steel strip to the succeeding steel strip is within the range of 0.90-1.10, rolled target thickness differenceΔh is≤0.1 times rolled target thickness h1 of the preceding steel strip and rolled target width differenceΔw is≤50 mm, it is decided that the preceding steel strip and the succeeding steel strip are the same and the rolling of the succeeding steel strip is started by using the actual value of rolling conditions used for the rolling control of the preceding steel strip for the rolling conditions of the succeeding steel strip. <P>COPYRIGHT: (C)2004,JPO&NCIPI</p> |
