Cold Rolled Sheets

Cold Rolled Sheets

Basing on the raw materials of high quality hot-rolled coil which has removed iron oxide after picked, cold-rolled sheet is made through reversing cold rolling deformation imposed on the group, annealing, formation, and exactness processes, including plate and volumes. A steel sheet, which is also known as box board or plate, is for delivery in sheets. A long roll known as the steel delivery is also known as coil.

Production Process

The sheets are not heated duing the process, so there are no pitting and skin defects such as iron oxide, but good-quality and smooth surface. And the accuracy of the cold-rolled products' size is high. The performance and organization of the product can meet some special requirements, such as the electromagnetic properties, deep drawing properties.

Rolling process speed: 1000m/min

Forms of energy: electricity, water, steam

Specification:

Thickness 0.15-1.2mm

Width 700-1250mm

Diameter: 6010mm

Diameter: 2000mm

Grade: Q195A-Q235A, Q195AF-Q235AF, Q295A(B)-Q345A(B): SPCC, SPCD, SPCE, ST12-15 DCO1-06

Performance: Mainly used in low carbon steel grades, requires a good cold bending and welding performance, and some stamping performance.

Application: cold-rolled products with excellent mechanical and processing properties and thickness of theprecise characteristics are widely used in construction, automotive, transportation and other industries, and as a hot dip for raw materials.

Cold Rolled sheet(annealing State): Whether the cold rolled sheet before the cover annealing, annealing after the processing hardening phenomenon, the internal stress elimination (greatly reduced), that is, the yield strength decreased close to the cold rolling before.

Product Features:
Because the production process is not heated, so there is no pitting and iron oxide skin defects, with good surface quality and high smoothness. And the high precision of cold-rolled products, the performance of the product and the organization can meet some special use requirements. The main use of low carbon steel grades, requires good cold bending and welding performance, as well as a certain punching performance.
