Cold Rolling Definition

It is rolling under recrystallization, but it is generally understood as rolling using normal temperature rolled materials. Aluminum cold rolling is divided into plate rolling and foil rolling, the thickness of 0.15~ above is called plate, 0.15~ below is called foil. Europe and America use 3~6 continuous rolling mills as cold rolling equipment.
Due to the absence of heating in the production process, there are no defects such as pitting and oxide sheet that often occur in hot rolling, and the surface quality is good and the finish is high. Moreover, the dimensional accuracy of cold-rolled products is high, and the performance and organization of products can meet some special requirements, such as electromagnetic properties and deep drawing properties.
Specification: Thickness of 0.2-4mm, width of 600-2 000mm, steel plate length of 1 200-6 000mm.
Grade: Q195A-Q235A, Q195AF-Q235AF, Q295A(B)-Q345 A(B); SPCC, SPCD, SPCE, ST12-15; DC01-06
Performance: Mainly used low carbon steel grades, requiring good cold bending and welding performance, as well as a certain stamping performance.
