Cold Rolled Aluminium Disc Circle Overview
Cold-rolled aluminum wafer refers to the use of hot-rolled aluminum coil as raw material. After surface treatment, the metal is cold-rolled below the recrystallization temperature. The finished product is a hard-rolled coil. In this way, the hardness of the aluminum wafer can be improved. , But it will also be accompanied by deterioration of metal plasticity.

Aluminum Plate Circle Applications
Cold Rolling Aluminum Circles are widely used in the furniture like tables. But most aluminum circles clients requested are Deep Drawing Quality Aluminum Circle.
These aluminum circles are widely used in kitchenware, cookware, reflector-light, vân vân.
Properties of the aluminum circle:
Aluminum circle is suitable for many markets, including cookware, automotive and lighting industries, vân vân., thanks to good product characteristics:
- Low anisotropy, which facilitates deep drawing
- Strong mechanical properties
- High and homogeneous heat diffusion
- Ability to be enameled, covered by PTFE (or others), anodized
- Good reflectivity
- High strength-to-weight ratio
- Durability and resistance to corrosion
Aluminum Circles Process
Ingot/Master Alloys — Melting Furnace – Holding Furnace — D.C. Caster — Slab —- Scalper — Hot Rolling Mill – Cold Rolling Mill – Punching – Annealing Furnace — Final Inspection – Packing — Delivery
- Prepare the master alloys
- Melting furnace: put the alloys into the melting furnace
- D.C.cast aluminum ingot: To make the mother ingot
- Mill the aluminum ingot: to make the surface and side smooth
- Heating furnace
- Hot rolling mill: made the mother coil
- Colding rolling mill: the mother coil was rolled as the thickness you want to buy
- Punching process: become the size what you want
- Annealing furnace: change the temper
- Final inspection
- Packing: wooden case or wooden pallet
- Delivery
Quality Control
Assurance Below inspection will be done in the production.
- a. ray detection—RT;
- b. ultrasonic testing—UT;
- c. Magnetic Particle Testing-MT;
- d. penetration testing-PT;
- e. eddy current flaw detection-ET
1) Be free from Oil Stain, Dent, Inclusion, Scratches, Stain, Oxide Discoloration, Breaks, Ăn mòn, Roll Marks, Dirt Streaks, and other defects which will interfere with use.
2) Surface without black line, clean-cut, periodic stain, roller printing defects, such as other gko internal Control standards.
Aluminum discs packing:
Aluminum circles can be packed by export standards, covering with brown paper and plastic film. Finally, the Aluminium Round is fixed on a wooden pallet/wooden case.
- Put the driers side the aluminum circle, keep the products dry and clean.
- Use clean plastic paper, pack the aluminium circle, keep good sealing.
- Use the snakeskin paper, pack the surface of the plastic paper, keep good sealing.
- Kế tiếp, there are two ways of packaging: One way is wooden pallet packaging, using the crusty paper packing the surface; Another way is wooden case packaging, using the wooden case packing the surface.
- Finally, lay the steel belt on the wooden box’s surface, keeping the wooden box fastness and secure.
Aluminum circle of Henan Huawei Aluminum. meet the export standard. Plastic film and brown paper can be covered at customers’ needs. What’s more, a wooden case or wooden pallet is adopted to protect products from damage during delivery. There are two kinds of packaging, which are eye to wall or eye to the sky. Customers can choose either of them for their convenience. Generally speaking, there are 2 tons in one package, and loading 18-22 tons in 1×20′ container, Và 20-24 tons in 1×40′ container.
