  • DMS 20Hi cold rolling mills Fives in Steel

    Mandrel greasing Fives has improved mandrel greasing substantially by making it a fully automatic rather than manual process. This saves greasing time of 15 minutes per mandrel per day and increases cold rolling mill productivity by 2~3%. Other advantages include the reduction of grease consumption and the increase of mandrel shaft lifetime.Hot Rolling Mill Hydraulic Gap Control (HGC) thickness,rolling mills can be achieved, then in some cases, cold rolling is not even required, which can result in a radical decrease of production costs.

  • Rolling (metalworking) Wikipedia

    In metalworking, rolling is a metal forming process in which metal stock is passed through one or more pairs of rolls to reduce the thickness, to make the thickness uniform, and/or to impart a desired mechanical property. The concept is similar to the rolling of dough.Rolling is classified according to the temperature of the metal rolled. If the temperature of the metal is above itsCold 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.
