PROBLEM TO BE SOLVED: To provide a fine surface finish and high-efficiency descaling method of a hot-rolled steel strip by which the productivity of the descaling is ensured even when manufacturing a hot-rolled steel strip having fine surface finish in the descaling of the hot-rolled steel strip. SOLUTION: Shot blasting is applied to the hot-rolled steel strip 10 by using shot particles of <0.30 mm in an average particle diameter and, successively, shot blasting is applied by using the shot particles of≥0.40 mm in the average particle diameter. Or, furthermore, pickling is applied after that. COPYRIGHT: (C)2007,JPO&INPIT
