Zusammenfassung:	PURPOSE: To prevent the occurrence of banding (rough surface) on rolls when manufacturing a ferritic stainless steel excellent in a ridging property by setting the draft of a hot rough rolling to a specific value or over by one pass. CONSTITUTION: When performing thickness drawing down with a draft 40% or over in the final stand of a rough rolling to a ferritic stainless steel (SUS430), by performing width drawing down before the thickness drawing down with a draft 2% or below, the occurrence of roll banding is prevented, the front face of a sheet is held clean, and the rough surface of a rolled material by horizontal rolls is prevented.
