Abstract (en)
[origin: WO9727955A1] In a process for descaling a workpiece (22), in particular rolling stock, the workpiece is moved past rotary descaling means, and at least one liquid jet which rotates around an axis of rotation that crosses the surface (23) to be descaled of the workpiece (22) is projected onto the surface (23) to be descaled. In order to cool down the workpiece (22) only to a minor extent and to generate a high spraying pressure with a low working liquid pressure, the liquid jet is intermittently generated, i.e. interrupted at intervals.
