The role of pickling cold rolled steel coils

Because the surface of the cold-rolled steel plate is brittle, hard, not suitable for processing, and the surface corrosion and rust prevention ability of the cold-rolled steel plate is poor, especially in the environment of high temperature and humidity, acid, alkali and salt composition, it is easy to oxidation, resulting in the mechanical properties of the steel and the quality of use, pickling can be a good solution to this problem, not only can remove rust on the surface of the cold-rolled steel plate, but also can prevent rust.

Cold rolled steel pickling also has the following two points:
1. Pickling cold rolled steel can avoid belt breakage in rolling accidents
If the cold rolling billet tin oxide is not clean, pressed into the surface of the steel strip, acid deficiency acid washing, cold rolling iron oxide black spots are black extension, and the surface of the strip to form a depression, the depression part of the tensile stress during the rolling process, reduce the plasticity of the strip, resulting in the broken strip is pulled off.
2, cold rolling steel pickling can make the surface of the steel plate smooth, remove rust, greatly reduce defective products
After pickling the surface of cold rolling, a passivation film is formed, which has no black spots and is smooth, improves its finish and beauty, and effectively improves the yield of steel coil.
