油污是指铝卷轧制后铝尖表面油过多.除轧制油膜外，还含有多余的油，肉眼可见于分切生产和产品检验，这些油主要是由辊颈或轧机出口上下甩、溅、滴在箱面、轧机清辊器异常、轧机测厚头滴油等形成的，往往脏成分凌乱。
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.
铝卷生产厂家提醒您，这种油污会对铝卷的外观造成很大的危害：一是铝卷产品大多作为装饰或包装材料，须有干净的外观；二是厚度薄，后续退火容易形成气泡，影响使用，由于油量大，这里残留过多。油污的缺点是评价铝箔质量的一个非常重要的指标。
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.

在生产过程中严格检查生产设备。如发现设备内油污过多，应及时清洗，找出原因，同时对生产产品进行板面清洗加工。不能清洗的产品无效的，禁止油污产品入库流入商场。
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.
此外划痕、划痕、划痕是铝卷表面的间歇性或连续的单沟伤痕。一般来说，当尖锐物与箔表面接触后相对滑动时。轧辊、导辊表面有尖缺点，或粘有硬杂物；机械导辊、剪切、卷、分切机械导辊、导线有尖缺点或枯萎杂物。划痕：束（或组）分布的疤痕由于物体之间的边缘和表面，或表面与表面接触后相对滑动或错误。
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.
