CONDUCTOR ROLL, PRODUCTION METHOD THEREFOR, AND REPAIRING METHOD THEREFOR

摘要

PROBLEM TO BE SOLVED: To provide a conductor roll having excellent corrosion resistance and peeling resistance, to provide a production method, and to provide a repairing method therefor. SOLUTION: A self-fluxing alloy thermal spraying layer having a hardness of≥450 Hv and a Cr plating layer are provided on the surface outside of a sleeve composing the barrel part of a roll from the sleeve side in order. On repair, the sleeve is removed, the self-fluxing alloy is thermally sprayed on the surface, remelting treatment is performed, and thereafter, the sleeve is fixed to the core metal of the roll by a shrinkage fit.
