Abstract

PURPOSE:To polish and grind the surface of a roll without causing bad influence on the quality of a strip, by performing polishing and grinding symmetrically in the longitudinal direction of the roll in a method of polishing and grinding the roll while rotating in a stand of rolling mill. CONSTITUTION:Respective work rolls 1a, 1b and back-up rolls 2a, 2b are processed at the same time while a strip A is running. The description of only the roll 1a is as follows; processing devices 3, 3' consisting of a pair of grind stones, grinding wheels, grinding cutters, etc. are brought into contact with the roll 1a and are moved (reciprocating motion) symmetrically with respect to the center of the longitudinal direction of the roll. Thus the roll 1a is processed bisymmetrically in its longitudinal direction, and the strip is not pushed to one side of the longitudinal direction of the roll during processing, and then the strip A is prevented from meandering. The same processings are performed for other rolls.
