铝板常见的有哪些质量问题?

来源:

在铝板带制作过程中,因为设备或许人员操作失误等原因简单出现质量问题,这儿铝业就常见质量问题总结如下,希望制作部分能够重视该问题。
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.
油污是质量问题中作为常见的:油污是指轧制后铝梢外表带油最过多.且带上了除轧制油膜以外的多余的油,在分切制作及成品检查过程中肉眼可见的外表带油。
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.
这些油主要是由辊颈处或轧机出口上、下方甩、溅、滴在箱面上以及轧机清辊器出现异常、轧机测厚头滴油等造成,且往往较脏成分复杂。
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.
这种油污将给铝卷外表带来危害较大:一是因为铝卷成品多数作为装修或包装材料,必须有一个洁净的外表二是其厚度薄,在后续的退火时易构成泡状,并且因为油量较多在该处构成过多的残留物而影响运用。油污缺点多少是点评铝箔质量的一项很重要指标。
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.


解决方法:在制作以前严厉检查制作设备,假如一旦发现设备中油污过多要及时清洗并且查找原因,同时对制作产品进行板面清洗加工,假如清洗不掉的产品做报废处理,有油污的产品禁止入库及流入市场。
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.
划伤是质量问题的常客:划伤、擦伤、碰伤是铝板外表呈现的断续或连续的.单条沟状伤痕。一般是尖锐物与箔材外表触摸后相对滑动时发生的。
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.
发生的主要原因:轧辊、导辊外表有尖状缺点,或粘有硬杂物剪切、合卷、分切的机械导辊、导路有尖状缺点或枯有杂物。
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.
擦伤:因为物体间棱与面,或面与面触摸后发生相对滑动或错动而在箱材外表造成的成束(或组)分布的伤痕。
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.
