Cold rolled steel coil is a kind of steel treated by cold rolling process, which has many excellent properties and wide applications. After the cold rolling process, it not only has a smooth surface, but also has high strength and ductility, which is suitable for various mechanical manufacturing and construction fields. The following will introduce the use of cold rolled steel coil and processing technology.

First, the use of cold rolled steel coil

1. Construction industry: Cold-rolled steel coils are often used in the manufacture of building structures. Such as steel structure buildings, Bridges, highway guardrail and so on. The high strength and excellent ductility of the cold-rolled steel coil make it able to withstand greater pressure and deformation, thus ensuring the structural stability and safety of the building.

2. Automobile manufacturing: Cold-rolled steel coil plays an important role in automobile manufacturing. It is usually used for the production of body, door, roof and other parts. Cold-rolled steel coil has high strength and toughness, which can effectively resist collisions and external shocks, and protect the safety of vehicles and passengers.

3. Electrical industry: Cold-rolled steel coil is widely used in the electrical industry, such as the manufacture of refrigerators, washing machines, air conditioners and other household appliances. Cold rolled steel coil has excellent corrosion resistance and electrical conductivity, making it an ideal material for electrical appliance manufacturing.

4. Furniture manufacturing: Cold-rolled steel coils also have great uses in furniture manufacturing. It is often used to make the skeleton and support structure of furniture. The high strength and durability of the cold-rolled steel coil make it able to withstand large loads and ensure the structural stability and service life of the furniture.

5. Other industries: Cold-rolled steel coil is also widely used in shipbuilding, railway equipment, petrochemical and other fields. Its corrosion resistance, high temperature properties and good machinability make it an indispensable material in these industries.

Second, the processing technology of cold rolled steel coil

1. Cutting: cold-rolled steel coils are often cut as needed during processing. Shearing refers to cutting the edge of a cold-rolled steel coil to the desired size and shape. Cutting can be done by means of mechanical cutting or laser cutting.

2. Crimp: During the processing of cold rolled steel coils, it is often necessary to crimp them into the desired shape. Crimp refers to the cold-rolled steel coil crimp into a cylinder, arc and other shapes. Crimping can be done by rolling or hydraulic pressure.

3. Bending: Cold-rolled steel coils can also be processed by bending. Bending refers to the deformation of the cold-rolled steel coil according to the desired bending Angle and curve. Bending is usually done using a bending machine or roll bending machine.

4. Welding: Cold-rolled steel coil in the process of processing, often need to be welded. Welding refers to joining together two or more parts of a cold-rolled steel coil. Usually using arc welding, gas welding and other methods for welding.

5. Surface treatment: cold rolled steel coils usually need surface treatment after processing. The surface treatment is to improve the durability and aesthetics of cold rolled steel coils. Common surface treatment methods are galvanized, spray, electroplating and so on.
