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.
Cold Rolled Steel Coil
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
Thickness 0.15-1.2mm
Width 700-1250mm
Diameter: 6010mm
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.
