COLD ROLLED
Cold rolled steel sheets offer a variety of outstanding properties, including easy formability and a smooth and clean surface, and are used in automobiles, appliances, furniture and many other everyday items.
Cold Rolling
The thickness accuracy of cold rolled products is determined by the cold rolling process.
Rolling force and strip tension are computer-controlled to minimize thickness deviations during rolling, based on measurements of the strip thickness at the entry and delivery sides of the mill.
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.
Finishing
After skinpass 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.
