Work Roll and Backup Roll non-contact region For the 'normal' material, the Mill runs with relatively low Roll Force (~200 Tons) and relatively high Negative Roll Bending (~-70 Tons). This combination with the ground-in Work Roll Crown results in a region where the Backup Rolls and Work Rolls do not touch during normal rolling operations.
Cold rolling is a work hardening process used to change the structure of metals and is often used to process stainless steel. Cold rolled stainless steel as a raw material has a wide variety of applications in medical, aerospace and automotive engineering.

A two-stand reversing cold mill can deliver capacities between 300,000 t/a of thin-gauge products or 1,000,000 t/a and more of thicker-gauge products. Main benefits of Primetals Technologies' reversing cold mills. High production capacity and yield. Flexible, low-cost rolling of a wide range of products, especially for small order lots.
When the roll mill has come to a complete stop the sample can be removed, thickness measured along with a hardness measurement. Pre-rolled samples will be used to measure thickness and hardness test. A data table should be constructed. The lab report should show a graph of hardness against % cold work. %cold work = 100 x (Initial Thickness ...
rolling mill, dedicated roll cooling systems are required to fulfill the required functions. Examples are suitable roll cooling and lubricationsystems to fully utilize the advantages of HSS rolls in hot strip mills, and selective roll cooling systems as a method to control the flatness of the strip in cold rolling mills.
WORK ROLLS FOR COLD ROLLING MILLS WORK ROLLS FOR HOTROLLING MILLS BACK-UPROLLS. Rolls ROLLS FOR COLD ROLLINGMILLS 2 During last years, cold rolling mills (for Steel, Cooper and Aluminium thin plate, sheet and strip) have undergone a large devolopment toward: e higher rolling speeds, e higher pressures,
Work rolls in hot strip mills wear due to friction between the roll surface and hot strip. (Back-up rolls wear as well, but under pressure with elastic deformation, the friction is much less, except for the high work roll roughness in the last stand of a sheet rolling tandem cold mill). The wear is uneven from one end of the barrel to the other.
rolled, cold rolled, intermediate annealed and in most cases grinded on the surface [2]. Flatness measuring – the flatness measuring roll On the exit side of the mill the strip is bent over a segmented roll, the flatness measuring roll. This roll measures the force on each segment and in this way the flatness of the strip can be decided.
