Cod Rolled Coil Plate
Production Process
In the production process of cold-rolled coils, due to the lack of heating, there are no defects such as pitting and iron oxide scale that commonly occur during hot rolling, resulting in excellent surface quality and high smoothness.
Cold rolled products have high dimensional accuracy, and their performance and structure can meet some special usage requirements, such as electromagnetic performance, deep drawing performance, etc.
The process flow of cold rolled coil mainly includes processing preparation, acid washing, cold rolling, annealing, and galvanizing or spraying, which ensure the high quality and wide applicability of cold rolled coil.
Specifications and Grades
The specifications of cold-rolled coils are diverse, with a thickness usually between 0.2-4mm, a width of 600-2000mm, and a steel plate length of 1200-6000mm.
Common cold-rolled low-carbon steel plate grades include Q195A-Q235A, Q195AF-Q235AF, Q295A (B) - Q345A (B), etc.
Performance and Characteristics
The surface of cold-rolled coils is bright, clean, and easy to be coated, making them widely used.
Cold rolled coils have high stamping performance, no aging, and low yield point, making them suitable for various fields that require high precision and excellent performance.
Application Field
Cold rolled coils are widely used in various fields such as automotive manufacturing, electrical products, locomotives and vehicles, aviation, precision instruments, food canning, and construction. For example, in automobile manufacturing, cold rolled coils are used to manufacture components such as body panels, wheel hubs, etc; In electrical products, it is used to manufacture electrical equipment such as motors and transformers.
