The cold rolling process typically involves several steps. Initially, the hot-rolled steel is cleaned to remove any scale, oxides, or impurities. The cleaned steel is then fed into the cold rolling mill, which comprises a series of rollers that progressively decrease the thickness of the steel. The deformation during cold rolling creates dislocations in the crystal structure of the steel, which are responsible for increased strength through strain hardening.
