Abstract
A continuous coating line includes a roll assembly exposed to molten metal. The roll assembly includes a roll rotatable relative to a bearing block. The roll includes a roll portion and a journal protruding from each end of the roll portion. The roll is made from a refractory ceramic material that is resistant to wear, abrasion, and corrosion when the roll is exposed to the molten metal.

A roll for use in a continuous coating line, wherein the roll comprises:
- a core comprising a generally cylindrical roll portion and a journal extending axially from each end of the roll portion;
- and
- a shell positioned about the core, wherein the shell comprises a refractory ceramic material, wherein the shell comprises a roll sleeve having a bore extending therethrough configured to receive the core, wherein the roll sleeve is positioned about the roll portion of the core, wherein the bore of the roll sleeve is sized to provide a clearance fit between an inner surface of the bore and an outer surface of the roll portion of the core having a clearance between the inner surface of the bore and the outer surface of the roll portion such that the roll sleeve is rotatable with the core without an additional coupler.
