Cold-rolled steel sheet is the abbreviation of ordinary carbon structural steel cold-rolled sheet, commonly known as cold plate. It is made of ordinary carbon structural steel hot rolled steel strip, after further cold rolling to make a thickness of less than 4mm steel plate. Because it is rolled at room temperature, no oxide sheet is produced, therefore, the surface quality of the cold plate is good, the dimensional accuracy is high, coupled with annealing treatment, its mechanical properties and technological properties are better than the hot-rolled sheet steel, in many fields, especially in the field of home appliance manufacturing, has gradually replaced the hot-rolled sheet steel with it.

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.

Manufacturing technique

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

Specifications and materials

The thickness is 0.2-4mm, the width is 600-2 000mm, and the length of the steel plate is 1 200-6 000mm.

Application area

Cold-rolled strip is widely used, such as automobile manufacturing, electrical products, rolling stock, aviation, precision instruments, food cans and so on.
