Cold Rolled and Spheriodized Annealed Steel Strips ...
Cold Rolled Steel Strip is produced, as the term suggests by the further rolling of strip produced by the hot strip mills. Prior to cold rolling, the mill scale has to be removed, normally by the Pickling Process which uses mechanical manipulation (around small diameter rolls) and acid to dissolve the surface scale.
Cold rolling - CONDAT
The bearing chocks of the working cylinders are subject to permanent wash out by cold rolling lubricants and are subject to heavy loads.The use of lubricants with excellent anti-wear properties and resistance to wash-out is essential. As with hot rolling, the spacing of greasing time is necessary to limit maintenance operations between each change of cylinder.
