Cold Rolled Steel Sheet

Basing on the raw materials of high quality hot-rolled coil which has removed iron oxide after picked, cold-rolled sheet is made through reversing cold rolling deformation imposed on the group, annealing, formation, and exactness processes, including plate and volumes. A steel sheet, which is also known as box board or plate, is for delivery in sheets. A long roll known as the steel delivery is also known as coil.

A cold-rolled steel sheet is produced by pickling a hot coil and rolling it uniformly at an appropriate temperature to a thinner thickness. Cold-rolled steel sheet is used in automobiles, home electrical appliances, construction, office equipment and as the material for coated steel sheet.

1. Sophisticated Surface And Dimensional Accuracy

A cold-rolling reduction rate of 40% or higher severely compromises the cohesiveness of a metal structure because it aligns the metal grains in the direction of rolling. However, recrystallization through the annealing processhardens the steel but eliminates the hard, brittle qualities resulting from the cold reduction process. Cold- rolled steel sheet that has undergone the annealing process has increased workability compared to cold-rolled sheet produced by the conventional method. Sheet and coil can be produced at various grades of workability by altering the annealing and cold-rolling conditions

2. Excellent Workability

Using the cold rolling process, cold-rolled steel plate undergoes annealing and temper-rolling to achieve a consistent, smooth surface with uniform thickness and flatness. Additionally, these treatments provide cold-rolled steel sheet and coil with superior mechanical properties. As a result, cold rolled sheet and coil have a high level of work-ability and are suitable for metallic coating, painting and other similar treatments.

3. Various Applications

Cold-rolled steel sheet and coil is essential to automotive and electrical appliance production as well as a wide range of other products requiring tons of highly workable steel of a consistent quality. They also serve as the base metal for tinplates, galvanized sheet and other coated steel products. Since they are used in such varied products, cold-rolled steel sheet must be available with a variety of properties. Increased demand for sophisticated and specialized products has prompted the production of specialized cold-rolled steel with properties like deep drawability and high tensile strength.
