Strip Cold Rolling. Strip cold rolling is a technology for metal sheet and strip rolling below recrystallization temperature. The raw material is usually hot-rolled steel strip or plate which is rolled by a cold rolling mill at normal temperature to produce steel profiles. Cold-rolled strip steel and steel sheet have advantages, such as smooth ...

the tention of temper rolling mill. WebApr 14, 2019 A temper mill processes steel sheets or plates in a conveyor system, passing them through a horizontal pass cold rolling mill stand to create the desired surface finish. The mill may also include a cut-to-length process and the steel may be recoiled to form a coiled finished product if desired.

The mill may also include a cut-to-length process and the steel may be recoiled to form a coiled finished product if desired. The heart of the temper mill is the cold rolling mill stand which provides the temper pass, creating the required surface finish. This can be a 2-high, 4-high or 6-high mill, either work-roll driven or back-up roll driven.
