Abstract
A workpiece is moved past a rotor descaling device, which intermittently sprays the workpiece with at least one liquid jet formed intermittently in dependence on angular positions of a rotor rotating on a rotational axis intersecting the surface (23) of the workpiece (22).
Claims10
Process for descaling a workpiece (22), particularly a rolled piece, wherein the workpiece (22) is moved past a rotor descaling device (1), with a liquid supply line (14) to a stator (12) and to a rotor (4) which is rotated relative to the stator (12) and provided with at least one nozzle (10) for the formation of a liquid jet, where at least one temporary interrupted liquid jet rotating on a rotational axis (3) intersecting the surface (23) of the workpiece (22) to be descaled is sprayed onto the surface (23) to be descaled, characterized in that the liquid jet is formed intermittently in dependence on angular positions of the rotor (4), wherein between the rotor (4) and the stator (12) an interrupting device (17) is located, which allows intermittent supply of liquid to a nozzle (10).
