油污是指鋁卷軋制后鋁尖表面油過多.除軋制油膜外，還含有多余的油，肉眼可見于分切生產和產品檢驗，這些油主要是由輥頸或軋機出口上下甩、濺、滴在箱面、軋機清輥器異常、軋機測厚頭滴油等形成的，往往臟成分凌亂。
Oil stain refers to excessive oil on the surface of aluminum tip after aluminum coil rolling. In addition to rolling oil film, it also contains excess oil, which can be seen visually in slitting production and product inspection. The oil is mainly formed by roll neck or mill outlet throwing up and down, splashing, dropping on the box surface, abnormal mill cleaner, and oil dripping from the thickness measuring head of the mill, and the dirty ingredients are often messy.
鋁卷生產廠家提醒您，這種油污會對鋁卷的外觀造成很大的危害：一是鋁卷產品大多作為裝飾或包裝材料，須有干凈的外觀；二是厚度薄，后續退火容易形成氣泡，影響使用，由于油量大，這里殘留過多。油污的缺點是評價鋁箔質量的一個非常重要的指標。
The aluminum coil manufacturer reminds you that this oil stain will cause great harm to the appearance of aluminum coil. First, aluminum coil products are mostly used as decoration or packaging materials, and must have a clean appearance; Second, the thickness is thin, and subsequent annealing is easy to form bubbles, affecting the use. Due to the large amount of oil, there is too much residue here. The defect of oil stain is a very important index to evaluate the quality of aluminum foil.

在生產過程中嚴格檢查生產設備。如發現設備內油污過多，應及時清洗，找出原因，同時對生產產品進行板面清洗加工。不能清洗的產品無效的，禁止油污產品入庫流入商場。
Strictly check the production equipment during production. If too much oil stain is found in the equipment, it shall be cleaned in time to find out the cause, and the production products shall be cleaned and processed at the same time. If the products that cannot be cleaned are invalid, oil contaminated products are prohibited from entering the store.
此外劃痕、劃痕、劃痕是鋁卷表面的間歇性或連續的單溝傷痕。一般來說，當尖銳物與箔表面接觸后相對滑動時。軋輥、導輥表面有尖缺點，或粘有硬雜物；機械導輥、剪切、卷、分切機械導輥、導線有尖缺點或枯萎雜物。劃痕：束（或組）分布的疤痕由于物體之間的邊緣和表面，或表面與表面接觸后相對滑動或錯誤。
In addition, scratches, scratches are intermittent or continuous single groove scars on the aluminum coil surface. Generally speaking, when the sharp object slides relative to the foil surface after contact. The surface of roll and guide roll has sharp defects or is stuck with hard debris; Mechanical guide roller, shear, roll, slitting mechanical guide roller and wire have sharp defects or withered impurities. Scratches: The scars distributed by bundles (or groups) are relatively sliding or wrong due to the edges and surfaces between objects, or after the surface contacts with the surface.
