Product Description
COLD ROLLED STEEL COIL
Cold-rolled coils are made of hot-rolled coils, which are rolled at room temperature below the recrystallization temperature, including plates and coils. Among them, those delivered in sheets are called steel plates, also called box plates or flat plates; those delivered in rolls are called steel strips, also called coil plates.
It is rolling under recrystallization, but it is generally understood as rolling using normal temperature rolling materials. Aluminum cold rolling is divided into plate rolling and foil rolling. Those with a thickness of 0.15~ or more are called plates, and those with a thickness of 0.15~ or less are called foils. Europe and the United States mostly use 3~6 continuous rolling mills as cold rolling equipment.
Since there is no heating during the production process, there are no defects such as pits and scales 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 structure of the products can meet some special requirements for use, such as electromagnetic properties and deep drawing properties.
Specifications: thickness 0.2-4mm, width 600-2 000mm, steel plate length 1 200-6 000mm.
Grade: Q195A-Q235A, Q195AF-Q235AF, Q295A(B)-Q345 A(B); SPCC, SPCD, SPCE, ST12-15; DC01-06
Performance: Low carbon steel grades are mainly used, requiring good cold bending and welding performance, as well as certain stamping performance.
