In the production process of aluminum coil, product quality problems are easy to occur due to the mistakes of machine equipment or personnel. Here, the technical personnel of the aluminum coil manufacturer summarize the common product quality problems as follows. We hope you can pay attention to the following phenomena:
Oil pollution is a common product quality problem. Grease refers to the excessive grease on the surface layer of the aluminum tip after rolling and the excessive grease outside the rolling oil film, which is visible to the naked eye during cutting, manufacturing and finished product inspection.
These oils are mainly caused by spraying, splashing, dripping of the surface layer of the box, abnormality of the roller cleaning agent, dripping of the measuring head of the mill, and are often dirty and complicated.
This kind of grease will cause great harm to the surface layer of aluminum coil. The finished products of aluminum coil are mostly used as decorative materials or packaging materials, and a clean surface layer is required; Secondly, due to its thin thickness, bubbles are easy to form during use.
In the subsequent annealing process, the plate will form excessive residual oil, which will interfere with its use. Oil stain defect is an important index to measure the quality of aluminum foil.
The main reasons are as follows: there are sharp defects on the surface layer of guide roller and idler, or there are hard impurities stuck; There are sharp defects or dry impurities in the mechanical guide roller, shear machine, winding machine and cutting guide rail.
Scratch: a group of scars formed on the surface layer of a box when the edges or surface layers between objects slide or are misaligned.
Let's stop here to analyze the related content of oil pollution in the common problems of aluminum coils. If you have anything you don't know, please come here to follow the website http://www.musicovering.com , discuss with us!
