Camber
on the rolls
Offset
on the rolls
Hardening of the rolls
Antifriction bearing
Camber
on the rolls
In order to get the uniform thickness of the plate by rolling process, one provides camber on the rolls. The convex shape of sheet is mainly due to deflection or bending of rolls like a beam. To counter this, chamber is ground on rolls in the opposite direction so that after deflection the surface in contact with the sheet becomes flat.
Hence,
the correct option is (A).
