Abstract:
A descaling nozzle that can efficiently remove scale from a steel sheet. A spray section at an end of the descaling nozzle includes a taper portion continuous with a large diameter portion that forms a cylindrical channel, a first orifice formed on an outlet side of the taper portion, a resonant chamber continuous with an outlet side of the first orifice and that has a dimension in a radial direction that is greater than a major axis of the first orifice, and a second orifice formed on an outlet side of the resonant chamber.
