Cold CRC Rolled Steel Coils

Cold Rolled Steel coil is a steel coil product made by cold processing of hot rolled coil or plate at room temperature.Compared with hot rolling, cold rolled steel coils usually have higher flatness and surface quality, and their mechanical properties and dimensional accuracy are better.

Cold rolled steel coil is directly rolled into a certain thickness by rollers at normal temperature and rolled into a whole coil by a winder. Compared with hot rolled coil, cold rolled coil has bright surface and high smoothness, but it will produce more intemal stress, SO it is often annealed after cold rolling.

Cold rolled steel coil manufacturing process：

1. Raw material preparation: The raw materials are usually hot-rolled coils or steel plates. These hot-rolled steels are cleaned and pre-treated to ensure that the surface is free of oil, impurities, etc.

2. Cold rolling processing:
Pickling or cleaning: Steel coils are cleaned and degreased to eliminate surface contaminants and ensure the smooth progress of subsequent processes.
Cold rolling process: The cleaned steel passes through a cold rolling mill and undergoes a series of rolls and pressures to gradually reduce its thickness and obtain higher surface flatness and dimensional accuracy. This step is usually done at room temperature, giving the steel a better surface quality while maintaining its hardness.

3. Additional processing (as required):
Quenching treatment: Some cold-rolled steel coils need to be quenched to improve their hardness and strength.
Re-cleaning and treatment: Cold-rolled steel may require re-cleaning or other special treatments to ensure that the surface is clean and meets specific technical requirements.

4. Inspection and packaging:
Quality inspection: Carry out quality inspection of steel coils, including inspection of size, surface quality, thickness, etc.
Packaging: After completing the quality inspection, the steel coils are packaged according to customer requirements to protect the product from damage and facilitate transportation and storage.
