Steel Strip: 1) Capacity: about 15,000 ton per month 2)Thickness: 0.20mm - 3.0mm

Description of Cold Rolled Steel Coil:

Cold rolling is a process by which the sheet metal or strip stock is introduced between rollers and then compressed and squeezed. The amount of strain introduced determines the hardness and other material properties of the finished product.

Production Process of Cold Rolled Steel Coil:

Pickling: To clean the dust and rust points on the surface.Cold Rolling:Digital rolling control system produces minimum thickness tolerance, helps to prevent twist and improve straightness.Slitting: Precise slitting machinery helps control the best width tolerance and avoid camber or cracker. Also we can make round or sharp edge with additional process and special machines.Heat treatment:Advanced annealing, tempering and hardening techniques will help to produce proper mechanical property of the products to insure our client’s usage with minimum harm to natural environment.

General pupose of Cold Rolled Steel Coil

Classification	Designation	Characteristics	Main applications
Commercial quality	SPCC SPCCT	Commercial quality suitable for bending fabrication and simple forming; this is thetype in greatest demand.	Refrigerators, cabinets, power distribution baords and drums.
Drawing quality	SPCD	Drawing quality second only tothat of SPCEN. Excellent uniformity.	Automobile floor and roof panels.
Deep-drawing quality	SPCE SPCF	Deep-drawing quality.With metallurgically controlled grain size, it retains its beautiful finish even after being deep-drawn.	Automobile fenders and quarter panels
Extra deep-drawing quality	SPCG	Extra-low-carbon steel sheets with highest workability	Automobile internal panels and deep-drawn parts

 

Features of Cold Rolled Steel Coil:

Quarter Hard material can be bent (perpendicular to the direction of rolling) on itself without fracturing. Half hard material can be bent 90º; full hard can be bent 45º. Thus, these materials can be used for in applications involving great amounts of bending and deformation, without fracturing.

Applications of Cold Rolled Steel Coil:

 Low carbon steel: cable armoring, parts made by stamping process, for production of core flux wire, for production of pipes, radiator fins, etc.
