Zusammenfassung:PROBLEM TO BE SOLVED: To provide a nozzle for descaling a steel plate which can efficiently descale.SOLUTION: In the nozzle 1 for descaling, a discharge part 20 at the tip of the nozzle has a discharge hole (a main flow orifice) 15 and a branch hole (a branch flow orifice) 19 communicated with a large diameter part 18 forming a cylindrical flow passage. The branch hole 19 discharges a part of water flow inside the large diameter part so as to generate cavitation in a boundary part with water flow discharged from the discharge hole 15.
