The primary purpose of cold rolling of steels is to reduce the thickness of the hot rolled steel strips (normally in the range of mm to 5 mm) into thinner thicknesses (usually in the range of mm to mm) which cannot be normally achieved during hot rolling in a hot strip mill. Besides reduction in thickness cold rolling is done for ...

Rolling schematic view Rolling visualization. In metalworking, rolling is a metal forming process in which metal stock is passed through one or more pairs of rolls to reduce the thickness, to make the thickness uniform, and/or to impart a desired mechanical property. The concept is similar to the rolling of is classified according to the temperature of the metal rolled.

Various types of mills have been invented and put in production. A high crown (HC) mill with a work roll bending system was developed for control over strip flatness [7]. Based on a HC mill, a HCW (HC mill with work roll shifting) mill, which adds a work roll shifting system, can better control strip flatness in the hot rolling process.

Cold rolling mills under normal operations produce copious quantities of combustible oil residues that can lead to fast fire spread. Mills using an emulsion as the rolling fluid (usually 510% of oil or animal fat in water) will also leave combustible residue because water evaporates due to the frictional heating during the rolling process.
