Cold Roll

Cold Rolling is a process of reducing the gage in steel coils by passing the steel in between rolls which apply pressure on the surface of the steel and squeezes the surface. As volume of steel remains unchanged, cold rolling results in substantial increases in length depending on the percentage of reduction. Cold Rolling is done to ensure close gage tolerances which are not achievable in the hot roll product. Cold Rolling closes the grain on the hot roll steel resulting in smoother surfaces. Various finishes can be possible by adjusting the finishes on the roll. Subsequent annealing after cold rolling also results in better microstructures which assists in drawing or forming operations.

The degree of Cold Rolling on any steel depends on the chemistry of the steel. In low carbon steels, around 65% reduction may be possible but in several high carbon and alloy steels prior annealing is necessary to achieve any reduction.
