Cold-rolled steel is a type of steel that has undergone further processing after the initial hot-rolling process. Once the steel undergoes hot rolling, you need to cool it with a finishing technique that lets you compress it using rollers at a relatively low temperature. After cold rolling, the steel may be further processed through annealing ...

SMS group offers single-stand cold rolling mills for a broad spectrum of aluminum alloys and thin strip and multi-stand tandem cold mills as the solution for a large production capacity. We completed our portfolio of cold rolling mills by the EDT rolling mill, especially designed for rolling and tempering of automotive grades.
Moreover, vibration may nucleate the damage to the mill equipment. It is worth noticing that the hot rolling mill usually includes few rolls, as in the 2-high and 4-high configurations (Figure 1b), being characterized by bigger and stiffer working and backup rolls, while in the cold rolling mill, the work roll is slender and smaller. Therefore ...

In simple terms, cold rolling is an industrial process used to change the material properties of sheets or strips of metal. The metal is fed between two rollers which compresses it. …
Strip cold rolling is a technology for metal sheet and strip rolling below recrystallization temperature. The raw material is usually hot-rolled steel strip or plate which is rolled by a cold rolling mill at normal temperature to produce steel profiles. Cold-rolled strip steel and steel sheet have advantages, such as smooth surface, high ...
