Cold Rolled Steel Coil and Its Application

Apr 11, 2023

Cold rolled steel coil is an important cold-processed product, which is processed by cold-rolling process. Its advantages include smooth surface, precise size, excellent mechanical properties, etc. The thickness of cold-rolled steel coil is usually less than 0.4mm, and the width can reach about 2m. In the manufacturing industry, cold-rolled steel coils are widely used in the manufacture of various parts, automobiles, home appliances, construction materials and other fields.

 

The production process of cold-rolled steel coils includes multiple steps such as raw material selection, steel plate pretreatment, rolling, degreasing, and polishing. Among them, the rolling link is the core process of cold-rolled steel coil manufacturing, and it is necessary to use a multi-roll rolling mill to roll the steel plate. The surface of the rolled steel plate will produce iron oxide scale, which needs to be degreased to obtain a smooth surface. In addition, polishing operations can further improve the surface quality of cold-rolled coils.

 

Some common cold rolled coil materials include carbon steel, alloy steel, stainless steel, etc. Specifically, common cold-rolled steel coil materials include Q195, Q235, SPCC, SPCD, DC01, DC03, etc. Different material types have different chemical compositions and mechanical properties, which can meet the needs of different industries and fields.

 

Cold rolled coil steel are widely used in the manufacturing industry. For example, in the automotive industry, cold-rolled steel coils are used to manufacture body structures, doors, roofs, hoods, and other components. In the home appliance manufacturing industry, cold-rolled steel coils can be used to make casings for home appliances such as refrigerators, washing machines, and air conditioners. In the field of building materials, cold-rolled steel coils can be used to manufacture building structural materials, roof panels, guardrails, etc.

 

In conclusion, cold-rolled steel coil is an important cold-worked product with excellent surface quality and mechanical properties, and is widely used in various fields of manufacturing. With the continuous advancement of technology, the production process and application fields of cold-rolled steel coils are also expanding.
