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.
Dans un procédé pour décalaminer une pièce (22), notamment un produit laminé, la pièce passe devant une installation de décalaminage rotative, et au moins un jet de liquide tournant autour d'un axe de rotation croisant la surface à décalaminer (23) de la pièce (22) est projeté sur la surface à décalaminer (23). Afin d'assurer un refroidissement juste minime de la pièce (22) et pour produire une pression de jet élevée avec une faible pression du liquide de travail, le jet de liquide est produit par intermittence.
