PROBLEM TO BE SOLVED: To provide a method of manufacturing a hot-rolled steel strip by which the hot-rolled steel strip is manufactured at high efficiency without complicating the control operation of a controller for controlling the conveying speed of a sheet bar. SOLUTION: When conveying the sheet bar SB to a finishing mill 5 by a conveying table 3 which is arranged between a crop shear 2 and a descaling device 4, the sheet bar SB is conveyed to the descaling device 4 at the same conveying speed as the speed just after the sheet bar SB is cut with a crop shear 2. When the tip distal end of the sheet bar SB wherein the oxidized scale is removed with the descaling device 4, reaches a predetermined position where is preset, the conveying speed of the sheet bar SB is slowed down to the speed at which the sheet bar can be bitten with the first stand of the finishing mill 5.
