NOZZLE FOR DESCALING STEEL PLATE, DEVICE FOR DESCALING STEEL PLATE, AND METHOD FOR DESCALING STEEL PLATE |
摘要 |
Provided is a decaling nozzle that can efficiently remove scale from a steel sheet. A discharge section 20 at an end of a decaling nozzle 1 includes a discharge hole (main flow orifice) 15 and a branch hole (branch flow orifice) 19 that are connected to a large diameter portion 18 that forms a cylindrical channel. The branch flow orifice 19 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 19 and water flow that is discharged from the discharge hole 15. |
