Cold rolled steel coil

Cold-rolled steel coil is a common steel product, widely used in construction, automobile, machinery manufacturing, electrical appliances and other fields. The specifications of steel coils include parameters such as thickness, width, length, and weight. Different specifications are suitable for different applications.
Generally speaking, the thickness range of cold-rolled steel coils is 0.18mm-3.5mm, the width range is 600mm-2000mm, the length is generally in the coiled state, and the weight varies according to the specifications. Depending on the use, the surface quality of cold-rolled steel coils also has different requirements. For example, for automobile manufacturing, the surface quality requirements are higher, generally “BA” level, while for some machinery manufacturing, “B” level steel coils can be used.
In addition, there are many types of materials for cold-rolled steel coils, including cold-rolled carbon steel, cold-rolled low alloy steel, cold-rolled high-strength steel, etc. Cold-rolled steel coils of different materials are suitable for different fields and requirements. When choosing cold-rolled steel coils, it is necessary to select appropriate specifications and materials according to specific uses and requirements.
Cold rolled steel coil is made from hot-rolled steel coil as raw material, which is subjected to acid washing to remove oxide skin and then subjected to cold continuous rolling. The finished product is rolled hard coil. Due to the cold work hardening caused by continuous cold deformation, the strength and hardness of the rolled hard coil increase, and the toughness and plasticity index decrease. Deep processing requires annealing treatment.
Due to the lack of heating during the production process of cold rolled steel coils, there are no defects such as pits and oxide scales that often occur during hot rolling. The surface quality is good and the smoothness is high. Moreover, the dimensional accuracy of cold rolled steel coils is high, and the performance and structure of the products can meet some special usage requirements, such as electromagnetic performance, deep drawing performance, etc.
