In the production process of 5A02 aluminum plate products, it is very easy to have product quality problems due to the incorrect operation of machinery and equipment or the actual operation of the staff. A summary of common product quality issues in the aluminum industry is shown below. Hope that the manufacturing unit can care about this issue.

Oil stains are very common in product quality problems: oil stains refer to the surface layer of the aluminum tip after cold rolling. It also carries unnecessary oil other than the rolling oil film, which is visible to the human eye during the whole process of segmentation, manufacturing and product inspection. The surface is oily. This kind of oil is mainly caused by throwing, splashing, dripping on the surface of the box at the roll neck or the upper and lower sides of the hot tandem rolling inlet and outlet, abnormal detection of the hot tandem roll cleaner, oil leakage from the hot tandem rolling thickness measuring head, etc. Dirty ingredients are complex.

The above is the explanation of the common quality problems of 5A02 aluminum plate products, I hope it will be helpful to everyone.
