What is the whole roll

The whole roll is relative to the composite roll, the roll body outer and center and roll neck with single material cast or forged, the roller body and the roller neck outer different microstructure and properties controlled by casting or forging process and heat treatment process and adjustment.
Forging roll and static casting roll belong to integral roll.
