Up to 0.45mm minimum
We are engaged in the manufacture and export of a massive range of Cold Rolled Close Annealed Coils that are known for their high tensile strength, corrosion resistance and durability. These coils are widely used in control panel boards, electrical lamination and pipes & tubes. The proposed range is made available in various thicknesses, to cater to the varied requirements of our precious customers.
Maximum Coil Width: 750mm
Thickness: Up to 0.45mm minimum
Process of CRCA coils: HR Slitting:
Here HOT Roll Coils are slited as per size required , our HR slitting Machine can slitt Coils upto
6 mm thickness
30 MT Maximum Coil weight
Coils are rolling as per required thickness, here we are having PLC Controller to monitoring entire movements on rolling mill which contain related software which show actual speed and movements of machinery our operators are Specially trained for accurate results, here we can reduce thickness of HR Coils up to 0.45mm, and process coils up to 750mm width, surface hardness, thickness are testing every passing as per IS 513:2008 standard.
We are committed to meet customers requirement along with maintaining all Standard.
After under going cold rolling coils are become very hard because of work hardening and loss of ductility
In order to restore ductility formability coils are annealed in to protective nitrogen-hydrogen atmosphere so that desired grain size and orientation is obtained
With use of Bell Furnace we annealed coils as per hardness required
Following are mechanical Properties for Annealed and Skin pass sheets and strips
After completing process of Annealing Coils are moved to skin pass, annealed cold roll coil are skin pass to prevent Strecure stains or wrinkles on formed component
To achieve flatness to impart matt or bright finishing as required
Cold roll coil further processes for slitting after skin pass, on C.R. Slitter as per requirement coils are slitted slitting size limit are minimum 30mm width
Cut to Length:
If steel strip is requirement of customer, coils are send to cut to length machine, here coils are cut as per require length
