ROLLING MILL ROLL-CLEANING DEVICE AND CLEANING METHOD.

摘要

A higher cleaning power is obtained by generating gas cavitation on the surface of a work roll (2) than by simply jetting a high pressure fluid alone, and contaminants on the surface of the work roll (2) can be reliably removed. Contaminants can be effectively removed while maintaining the coarseness of the surface of the work roll (2) by cleaning while keeping the distance (X) between the cleaning nozzle (41) and the surface of the work roll (2) and the pressure of the high pressure fluid within prescribed ranges.
