在鋁板帶制作過程中，因為設備或許人員操作失誤等原因簡單出現質量問題，這兒鋁業就常見質量問題總結如下，期望制作部分能夠重視該問題。
In the production process of aluminium sheet and strip, because of equipment or personnel operating errors and other reasons, there are simple quality problems. Here, the aluminium industry summarizes the common quality problems as follows, hoping that the production part can pay attention to this problem.
油污是質量問題中作為常見的：油污是指軋制后鋁梢外表帶油較過多.且帶上了除軋制油膜以外的多余的油，在分切制作及成品檢查過程中肉眼可見的外表帶油。
Oil contamination is common in quality problems. Oil contamination refers to the excessive oil on the surface of aluminium tip after rolling, and the excess oil besides rolling oil film, which can be seen by naked eyes in the process of slicing, fabrication and inspection of finished products.
這些油主要是由輥頸處或軋機出口上、下方甩、濺、滴在箱面上以及軋機清輥器出現異常、軋機測厚頭滴油等造成，且往往較臟成分復雜。
These oils are mainly caused by throwing, splashing, dripping on the surface of the box, abnormal roll cleaner and oil dripping on the thickness gauge head of the rolling mill at the neck of the roll or at the exit of the mill, and are often complicated in composition.
這種油污將給鋁卷外表帶來危害較大:一是因為鋁卷成品多數作為裝修或包裝材料，必須有一個潔凈的外表二是其厚度薄，在后續的退火時易構成泡狀，并且因為油量較多在該處構成過多的殘留物而影響運用。油污缺點多少是點評鋁箔質量的一項很重要指標。
This kind of oil pollution will bring great harm to the appearance of aluminium coil. First, because most of the finished products of aluminium coil are used as decoration or packaging materials, they must have a clean appearance and their thickness is thin. It is easy to form bubbles during subsequent annealing, and the use of aluminium coil is affected by the excessive amount of oil residues in the area. The defect of oil pollution is an important index to evaluate the quality of aluminium foil.

解決方法：在制作以前嚴厲檢查制作設備，假如一旦發現設備中油污過多要及時清洗并且查找原因，同時對制作產品進行板面清洗加工，假如清洗不掉的產品做報廢處理，有油污的產品禁止入庫及流入市場。
Solution: Strictly inspect the production equipment before making. If it is found that there is too much oil in the equipment, it is necessary to clean and find out the reason in time. At the same time, it is necessary to clean the surface of the production products. If the products that can not be cleaned are scrapped, the products with oil pollution are prohibited from entering the warehouse and entering the market.
劃傷是質量問題的常客：劃傷、擦傷、碰傷是鋁板外表呈現的斷續或連續的.單條溝狀傷痕。一般是尖銳物與箔材外表觸摸后相對滑動時發生的。
Scratches are frequent customers of quality problems: scratches, scratches and bruises are discontinuous or continuous on the surface of aluminium sheets. Single groove wounds. It usually happens when sharp objects and foil surface touch and slide relatively.
發生的主要原因:軋輥、導輥外表有尖狀缺點，或粘有硬雜物剪切、合卷、分切的機械導輥、導路有尖狀缺點或枯有雜物。
The main reasons for the occurrence are as follows: the appearance of rolls and guide rolls has pointed defects, or there are hard debris shearing, winding, slitting mechanical guide rolls, guide way has pointed defects or dry debris.
擦傷:因為物體間棱與面，或面與面觸摸后發生相對滑動或錯動而在箱材外表造成的成束(或組)分布的傷痕。
Scratches: Bundles (or groups) of scars on the outside of a box caused by relative sliding or dislocation of edges or surfaces between objects after touching.
