Cold rolled steel sheet

Cold-rolled steel sheet is processed by multiple rolling of cold rolling mill. After multiple cold rolling, the thickness of the steel sheet gradually decreases, the thickness of the steel sheet gradually becomes uniform, and the strength becomes higher. Wanzhi Steel has 13 years of production experience. The factory has four sets of rolling mills and can produce 200,000 tons of cold-rolled products a year. Please contact us for details.

Characteristics of cold-rolled steel sheet

1. Good surface quality

The production process of cold-rolled steel sheet is fine. During the manufacturing process, it has been rolled many times, so that its surface is fully processed, the gloss is better, and the appearance is smooth and beautiful. There will be no defects such as pitting and pressed iron oxide.

2. High dimensional accuracy

The cold-rolled steel sheet is produced by cold rolling process. The steel sheet produced by cold rolling process has high dimensional accuracy, and the error can be guaranteed within 0.1mm. The thickness difference of strip steel is generally not more than 0.01-0.03mm or less.

3. High hardness

Due to the large deformation and grain refinement of cold-rolled steel plates during the rolling process, the strength and toughness of the steel plates are increased, so the cold-rolled steel plates have high hardness and good wear resistance.

4. Good machinability

Cold-rolled steel plates are easy to process and have good processing performance.

5. Recyclable

Cold-rolled steel plates can be recycled and will not pollute the environment.

Application of cold-rolled steel plates

Cold-rolled steel plates are often used to make various industrial parts due to their high dimensional accuracy and high hardness. The main application areas include automobile manufacturing, construction, home appliances, machinery manufacturing, etc.

1. Automobile manufacturing field

In the automobile manufacturing field, cold-rolled steel plates are used to manufacture car bodies, doors, ‌engine hoods and other parts due to their good processing performance and high hardness.

2. Construction field

In the construction field, cold-rolled steel plates are often used to manufacture steel structures, bridges, ‌columns, stairs, handrails, exterior wall components, doors, etc., using their high strength and weldability.

3. Home appliance field

In the field of home appliances, cold rolled steel sheets are often used to manufacture the shells and structural parts of home appliances, such as refrigerators, washing machines, water heaters, air conditioners, etc., due to their high strength and good appearance quality.

4. Machinery manufacturing

Due to the characteristics of high hardness, high strength and good toughness, cold rolled steel sheets are often used to manufacture various mechanical equipment parts in the field of machinery manufacturing, such as bearings, gears, shafts, etc.

In addition to the above applications, cold rolled steel sheets can also be used to manufacture steel pipes and electronic parts.

Is it better to use cold rolled steel sheets or hot rolled steel sheets for automobiles

In automobiles, both cold rolled steel sheets and hot rolled steel sheets are used, but the scope of application is different.
Cold rolled steel sheets are more suitable for car bodies, because cold rolled steel has high strength and light weight, which can reduce the weight of the car body on the one hand, enhance the strength of the vehicle on the other hand, and reduce the procurement cost. In addition to the car body, cold rolled steel sheets can also be used to produce automobile parts, various reinforcements and anti-collision parts.

Due to the relatively strong tensile strength of hot-rolled steel plates, hot-rolled steel plates are mainly used on the longitudinal and transverse beams of large trucks with relatively high requirements.

What should be paid attention to in the appearance of cold-rolled steel plates during acceptance?

First of all, the surface of the cold-rolled steel plate must be clean and silvery white in color. Some local oxide marks are allowed on the unpolished surface. There is no peeling and cracking visible to the naked eye on the cut edges.

Conclusion

There are many factors to consider when choosing cold-rolled steel plates, such as the width, thickness, length, surface quality, price, etc. of cold-rolled steel plates. When choosing manufacturers, we should not blindly pursue low-priced products, but consider the production capacity and product quality of suppliers. You can choose the cold-rolled steel plates that suit you by comparing multiple suppliers. Wanzhi Steel can provide you with high-quality cold-rolled steel plates, and the price also has certain advantages. You are welcome to contact us at any time.
