Cold Rolled Steel Coil

It refers to the steel coil processed by the cold rolling process. Cold rolling process is a process of rolling hot rolled steel coil at room temperature or below recrystallization temperature. This process can further improve the hardness and strength of the steel. And that can give it excellent corrosion resistance and good processing properties.

In the production process of this steel coil, the main operating steps are as follows:

Raw material preparation: Use qualified hot-rolled steel coil as raw material to ensure that its surface has no serious defects and dimensional accuracy meets the requirements.

Pickling treatment: Hot rolled steel coil through pickling equipment to remove surface rust, oil and other impurities. This allows a clean surface to be prepared for the subsequent cold rolling process.

Cold rolling process: The pickling coils are sent to the cold mill for rolling. During the rolling process, the workers adjust the parameters of the mill such as deceleration, speed and tension according to the required plate shape and plate thickness.

Quality control: In the cold rolling process, the factory will strictly monitor the shape, thickness and surface quality of the steel plate to ensure that the product meets the relevant standards and customer requirements.

Cold Rolled Steel Sheet

Cold-rolled steel plate is a steel plate formed by rolling hot-rolled steel at room temperature or below the recrystallization temperature. Its thickness is usually no more than 8 mm, no less than 0.1 mm. Moreover, the factory can customize the size according to the needs of customers. It has high hardness and strength, as well as good processability and corrosion resistance.

The operation process of this steel plate mainly includes the following steps:

Raw material selection: According to product requirements and specifications, select the appropriate hot-rolled steel as raw material.

Pretreatment: Pretreatment operations such as cutting, leveling. And removing rust and slag are carried out on hot-rolled steel. It can ensure that its surface is smooth and without defects.

Cold rolling process: The pretreatment steel plate is sent to the cold mill for rolling. During the rolling process, the workers adjust the parameters of the mill according to the desired thickness and plate shape.

Follow-up treatment: The worker performs subsequent operations such as cutting, straightening and surface treatment as needed. This can fully meet the customer’s specific requirements for the product.
