To provide a method for manufacturing a hot-rolled steel strip of longitudinally uniform material quality in which the finish rolling temperature is set to be not lower than the target value over the entire zone in the longitudinal direction even in a thin hot-rolled steel strip or a material to be specially manufactured while it is difficult to ensure the finish rolling temperature.
In a hot-rolled steel strip manufacturing method in which a slab is roughly rolled by a roughing-down mill 2 to form a rough bar A, the rough bar is subjected to the accelerated finish-rolling by a finish rolling mill 6 to form a hot-rolled steel strip, and this hot-rolled steel strip is cooled, only a forward end portion of a predetermined rough bar and a rear end portion of the predetermined rough bar are heated by a heating device 4 disposed on the inlet side of a finish rolling mill 6.
