Cold rolling aluminum sheet plate

Cold rolling of aluminum strip is usually carried out on a four-high or six-high mill. The cold rolling process of aluminum strip is generally divided into rough rolling, intermediate rolling and finishing rolling. Rough rolling and intermediate rolling focus on increasing pressure, strengthening the production process, and shortening the production cycle. The viscosity of the rolling oil is greater than the finishing time; the finishing focuses on ensuring the surface roughness and shape of the product.
Cold-rolled aluminum sheets and strips require finished or intermediate annealing, and have higher requirements on product surface quality, shape and surface brightness. In addition, aluminum is also easy to stick to the roll during cold rolling, resulting in a decrease in the quality of the rolled surface. Therefore, the cold rolling oil for aluminum strip with good performance should meet the following requirements:
①The viscosity is moderate and the lubricating effect is appropriate.
②Narrow distillation range, high flash point and good safety.
③It has good cooling property, which can reduce the temperature of the roll and the rolling piece and control the shape of the plate.
④No corrosion to rolls and equipment.
⑤ Low sulfur, low aromatics, no oil stains on the surface of the strip after rolling and annealing.
⑥ Non-stick roll, easy to filter.
⑦Convenient maintenance and management.
⑧ Non-toxic, low odor, in line with environmental protection requirements.


How to distinguish hot rolled aluminum sheet from cold rolled aluminum sheet

(1) If it is a cold rolled or hot rolled product, usually the hot rolled product surface is brighter.

(2) Electron microscope analysis can not be seen, crystal image can see the difference.

(3) Visual inspection can roughly judge, the simple method is to test the elongation.

Aluminum sheet plate standard export packing

  • The aluminum plate is paperclip or laminated to ensure that the surface of the aluminum plate is intact and free of scratches;
  • Plastic film ( HDPE, PVC, PE or PET etc ) protection or hard kraft paper wrapping is used to prevent moisture and rain to ensure that the aluminum plate is clean and free of dirt during transportation (each package has a moisture-proof desiccant to ensure the quality of our products in East China and South China, where there is more rain);
  • Installed with wooden brackets and reinforced with steel straps to avoid collision during transportation and to ensure the geometry of the aluminum plate remains unchanged;
  • For export products, we use wooden boxes and pallets with fumigation mark for packaging;
  • We can also pack according to other packaging requirements of customers;
