<p>PROBLEM TO BE SOLVED: To provide a hot rolled strip having good flatness and good rolled state by specifying the tension applied between each rolling stand in a specified range when finishing the hot rolled strip by a continuous hot finishing mill. SOLUTION: A slab heated to a prescribed temp. is subjected to rough rolling by a roughing mill to a rough bar, successively, finish rolling by a continuous hot finishing mill consisting of plural stands to a hot rolled strip. At this time, for the hot rolled strip rolled by a continuous hot finishing mill, the tension applied between each rolling stand is specified in a range of 2-10kgf/mm<2> . By this method, generation of deformation to the hot rolled strip is prevented so as to improve flatness and enable stabilized finish rolling, the hot rolled strip excellent in quality is produced in high yield.</p> |
