Zusammenfassung:Provided is a descaling nozzle that can efficiently remove scale from a steel sheet. A discharge section at an end of a descaling nozzle includes a discharge hole (main flow orifice) and a branch hole (branch flow orifice) that are connected to a large diameter portion that forms a cylindrical channel. The branch flow orifice discharges a part of water flow in the large diameter portion so that cavitation occurs at a boundary between the part of water flow discharged from the branch flow orifice and water flow that is discharged from the discharge hole.
