Rolling (metalworking) - Wikipedia

Hot rolling is a metalworking process that occurs above the recrystallization temperature of the material. After the grains deform during processing, they recrystallize, which maintains an equiaxed microstructure and prevents the metal from work hardening. The starting material is usually large pieces of metal, like semi-finished casting products, such as slabs, blooms, and billets.

Annealing of Cold Rolled Steel – IspatGuru

During cold rolling process the reduction in thickness is due to plastic deformation which occurs by means of dislocation movement. Steel gets hardened because of the buildup of these dislocations. These dislocations reduce the ductility of cold rolled steel making it useless for forming operation.

Metallurgical Processes and Defects in Steel

Rolling defects. The common rolling defects of steels are given below. During the hot rolling, if the temperature of the steel is not uniform then the flow of the material occurs more in the areas having higher temperature and less in the parts with lower temperature. High temperature difference results into cracking and tearing.
