Cold rolling is mainly performed by tandem mills consisting of successive mill stands. These stands gradually reduce the thickness of the strip by entraining it through friction into the roll bite, inbetween their work rolls. European tandem mills were mostly built at least 30 years ago, when rather soft steel grades were cold rolled.
