Some questions about 3003 Aluminium Sheet products
08-01
In the production process of 3003 Aluminium Sheet products, quality problems are prone to occur due to equipment or personnel errors.
Oil pollution is a common problem in quality: oil pollution refers to the surface of the aluminum tip after rolling with too much oil, and with excess oil other than the rolling oil film, the surface visible to the naked eye in the process of slitting production and finished product inspection with oil. These oils are mainly caused by throwing, splashing, and dripping on the box surface at the roll neck or the top and bottom of the rolling mill outlet, abnormality of the roll cleaner of the rolling mill, and oil dripping from the thickness measuring head of the rolling mill, etc., and are often dirty and complicated.
This kind of oil pollution will bring greater harm to the surface of the aluminum coil: first, because most of the finished aluminum coils are used as decoration or packaging materials, they must have a clean surface; second, their thickness is thin, and it is easy to form bubbles during subsequent annealing. Moreover, due to the large amount of oil, too much residue is formed there, which affects the use. The number of oil defects is a very important indicator for evaluating the quality of aluminum foil.
Solution: Strictly check the production equipment before production. If you find that there is too much oil in the equipment, you should clean it in time and find the cause. At the same time, the surface of the production products should be cleaned and processed. If the products that cannot be cleaned are scrapped, the products with oil pollution It is forbidden to enter the warehouse and enter the market.
Scratches are a frequent source of quality problems: Scratches, scuffs, and bumps are intermittent or continuous single groove-like scars on the surface of 3003 Aluminium Sheet products. Generally, it is generated when the sharp object is in contact with the surface of the foil and slides relatively.
