Claim Text:
1. A cleaning device for a rolling roll, the cleaning device comprising a cavitation nozzle that is used for cleaning a work roll used in a rolling mill, wherein in order to clean zinc adhered to a surface of the work roll while keeping surface roughness of the work roll, a distance X between a tip end of the cavitation nozzle and the surface of the work roll is set in a range of 30 mm to 40 mm; a pressure PH of high pressure fluid squirted from the cavitation nozzle is set in a range of 20 MPa to 40 MPa; a pressure PL of low pressure fluid squirted from the cavitation nozzle simultaneously with the high pressure fluid is set in a range of 0.03 MPa to 0.07 MPa; and the pressure PH of the high pressure fluid satisfies PH≦0.5X+20.
