Cold rolling is a process by which metal is passed through rollers at temperatures below its recrystallization temperatures. The metal is compressed and squeezed, increasing the yield strength and hardness of the metal. During the cold rolling process, when the metal is put under mechanical stress, it causes a permanent change to the crystalline structure of the metal. This causes an increase in its strength and often improves corrosion resistance. It is the line where the oxide layers formed on the surface of hot rolled materials are cleaned by passing through Hydrochloric Acid (HCL) baths. Cold rolling refers to the process of reducing the thickness of a material, typically ranging from 6 mm to 0.06 mm, by passing it through a series of rollers at temperatures between 60°C and 180°C.
