Jan 21, 2019 The cold rolling mill is usually fitted with thickness gauges that check the steel as it comes out of the rollers. Reversing mills are designed so that the steel can be reversed and pushed back through the rollers which are brought closer together each time until the desired thickness is achieved. Multi-stand mills have three to six pairs of

Oct 06, 2020 The flatness control in cold rolling mill is carried out through automatic flatness control (AFC). The control tasks which are to be achieved in the Level 1 closed-loop control for cold rolling mill concerns not only the thickness (AGC) but also the flatness (AFC). For a strip subject to cold rolling, the flatness is defined as the amount of

Sep 30, 2020 In the rolling process, the job is drawn through a set of rolls due to interface friction, and the compressive forces reduce the thickness of the workpiece or change in its cross-sectional area.. The types of rolls used in rolling mills are depended upon the shape, size and the gap between the rolls and their contour. Because of workability and limitations in equipment, rolling is done in the
