Precision Work Roll and Back-Up Roll Chocks

The chocks form part of the rolling mill structure operating in a large Aluminum manufacturing plant. 

Back-up rolls press on smaller work roll that are in contact with the work, next was the intermediate roll and they were quite a bit longer but only about 2ft in diameter.

Chocks for work roll are used forged, and for back-up roll casting, the backup and intermediate rolls were to keep the center rolls from flexing causing uneven thickness.
