Cold-rolled coil is an important industrial material, and its production process involves a variety of equipment and processes, including raw material preparation, pickling, rolling, degreasing, annealing (heat treatment), finishing, etc.

Product advantages

1. The surface of cold-rolled coils is smooth and even in color. Not only does it give it a unique appearance, but more importantly, this surface treatment method gives the cold-rolled coil a good silver luster effect, which greatly enhances its commercial value.

2. Cold rolled coils have excellent processing performance and weldability. This means it can be easily cut, trimmed, stamped and welded during the production process to meet the specific needs of different industries. This flexible production method makes cold rolled coil widely used in various industries.

3. Cold rolled coils have high strength and hardness, good wear resistance and long service life. This is because it has undergone cold working during the manufacturing process, making its internal grains finer and denser, thus improving its mechanical properties. This characteristic allows cold-rolled coils to remain stable when subjected to high loads and complex working conditions, extending their service life.

Daily applications of cold rolled coils

There are many grades of cold rolled coils, mainly Q195A-Q235A, Q195AF-Q235AF, Q295A(B)-Q345 A(B), SPCC, SPCD, SPCE, ST12-15, DC01-06, etc. These brands are mainly used in various industries such as automobile manufacturing, electrical products, rolling stock, aviation, precision instruments, and food cans.

Cold-rolled coils can also be used to produce stainless steel coils, the main grades of which are 301, 304, 316, 430, etc. These brands are mainly used in tableware, medical equipment, household appliances, etc.

In the field of automobile manufacturing, cold-rolled coils are mainly used to produce body steel plates, automobile parts, etc. In the field of electrical products, cold-rolled coils are mainly used to produce motor casings, transformer casings, switch cabinets, etc. In the field of rolling stock, cold-rolled coils are mainly used to produce car bodies, roofs, doors, etc. In the aviation field, cold-rolled coils are mainly used to produce aircraft skins, wings, etc. In the field of precision instruments, cold-rolled coils are mainly used to produce instrument housings, sensor housings, etc. In the field of food cans, cold-rolled coils are mainly used to produce can containers, can lids, etc.

In short, the production process of cold-rolled coils involves a variety of equipment and processes, and its grades and application fields are very wide. It is an indispensable and important material in modern industrial production.
