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 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 …

From Cold-Rolling to Annealing. Pickled coils are rolled to the specified thickness . by cold rolling. The Cold-Rolled Steel Sheets and Coils have their crystal grains enlarged in the rolling direction, making the texture hardened and brittle. In the annealing process, the coils are continuously heated in reductive atmospheric gas to form uniform

Fig 2, Heat Migration in Cold Mill Work rolls (Hotter regions shown in red) This localized heat input / output process results in a non-uniform distribution of heat, circumferentially around the roll and transversely across the roll body. Additionally the roll is subjected to Thermal and Mechanical Fatigue during rolling:

A) Thread/Gear Rolling. The thread/ gear rolling is a cold-forming type of rolling process used to cut gear or threads on a cylindrical blank. In this process, the threaded dies are fitted on cylindrical rollers of the rolling machine. The cylindrical blank presses the threaded roller and roll against the faces, which displace the material and ...
