PROBLEM TO BE SOLVED: To provide a device for removing scale of a material to be rolled, especially shapes in which the device is composed of at least a spraying component assembly for a descaling agent to flow out of many nozzles comprising nozzle heads and flowing out openings and is constituted so that the material to be rolled is transferred beside the spraying component. SOLUTION: A spraying component assembly 1 is rotatably supported and is capable of being locked at a working rotation position and the nozzles form many nozzle sets 5 provided in the radial direction to the spraying component at intervals to each other. Then, these nozzle sets extend and stay along the rotation axis line of the spraying component. Further, each one set of the nozzle sets 5 is suited to a sectional profile of a shape 4 through which each of the nozzle sets 5 passes and is rotatable and adjustable. |
