1 .Cold rolled steel sheet Introduction
Cold rolled sheet has superb sheet shape and surface quality with good flatness and surface finish. The surface of the cold sheet is clean and bright and easy for coating. The varieties of cold rolled sheet are widely used in galvanized substrates, home appliances, tubing, automobiles, building, enamels and other industries.
Cold rolled steel sheets offer a variety of outstanding properties,including easy formability and a smooth, clean surface, and are used in automobiles, appliances, furniture, and many other everyday items.

7.The production process
Cleaning
Rolling oil on the cold rolled strip is burned off during annealing, which is the next process after cold rolling. Other types of rolling oil are removed by electrolytic cleaning prior to annealing. In particular, electrolytic cleaning is used with products which require a clean surface to ensure good paintability
Annealing
The formability of products is determined by annealing. Because cold rolling significantly increases material hardness, making forming difficult, annealing is performed to improve ductility by inducing a recrystallized structure in the steel. As the annealing process, coils are piled and covered by the box and annealed and this is called the batch annealing. The other is the continuous annealing process, in which coils are continuously treated.
Skin pass rolling
Annealed coils are lightly rolled by the skin pass mill to prevent a defect called stretcher strain, improve strip shape, and adjust mechanical properties. Skin pass rolling is also used to produce dull finish and bright finish products.
Finishing
After skin pass rolling, coils are processed at the recoiling line, where they are cut to produce product coils of the specified weight, or at the shearing line, where they are cut to sheets of the specified dimensions. Product thickness, width, shape, and surface quality are inspected, and mechanical properties are tested using specimens taken at the finishing line.
