进步铝卷产品质量预处理工作是进步销量的前提

铝卷产品被广泛应用于汽车、建筑等行业，进步铝产品的质量是企业生存的根本所在，铝质材料在空气中是极不稳固的河北人事考试网首页，容易生成用肉眼也难以识别的氧化膜。因为铝件加工工艺方法的不同，如铸造成型，或是由延压板材直接剪切而成豪沃A7驾驶室，或是机械邃密加工成型，或是经不同工艺成型后又经热处理或焊接等果皮箱，工件外观都会呈现不同状况，不同程度的污物或痕迹，为此在前处理工序中必须根据工件外观的现实情况选择前处理的工艺方法。
Aluminum coil products are widely used in automotive, construction and other industries, improving the quality of aluminum products is the fundamental survival of enterprises, aluminum materials in the air is extremely unstable, easy to generate with the naked eye is also difficult to identify the oxide film. Due to the different processing methods of aluminium parts, such as casting molding, or directly shearing from the rolled sheet metal, or mechanical fine processing molding, or heat treatment or welding after forming by different processes, the surface of the workpiece will show different states, different degrees of dirt or traces, so it must be in the pretreatment process. According to the actual situation of the workpiece surface, the pretreatment method should be selected.
铝镁锰板预处理工艺中必要细致，铸造成型件并非所有外观都经过机械加工，未经机加工的外观留有浇铸过程中形成的过厚氧化层，有的还夹有砂层，此时应先用机加工或喷砂方法先除去这一部位的原始氧化膜，或是经碱洗后再加工，只有如许才能既除净未加工部位的原始氧化层，又可避免机加工部位公差尺寸的改变。

In the pretreatment process of aluminium sheet, it should be noted that not all the surfaces of the casting parts are machined. The surface that has not been machined has a thick oxide layer formed during the casting process, and some are sanded. At this time, the original oxide film of this part should be removed by machining or sandblasting first, or after alkali washing, and then added. Only in this way can the original oxide layer of the unprocessed part be removed and the change of tolerance size of the machined part be avoided.

油污是质量题目中作为常见的：油污是指轧制后铝梢外观带油最过多.且带上了除轧制油膜以外的多余的油，在分切生产及制品检查过程中肉眼可见的外观带油。这些油重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非常、轧机测厚头滴油等造成，且每每较脏成分复杂。
Oil stain is a common quality problem: oil stain refers to the greatest amount of oil on the surface of the aluminum tip after rolling, and carries excess oil except the rolling oil film, which is visible to the naked eye in the process of cutting production and product inspection. These oils are mainly caused by throwing, splashing, dropping on the box surface at the roll neck or at the exit of the mill, abnormal roll cleaner and dropping oil from the gauge head of the mill, and are often more complicated in dirty composition.
这种油污将给铝卷外观带来危害较大:一是因为铝卷制品多数作为装饰或包装材料，必须有一个洁净的外观;二是其厚度薄，在后续的退火时易形成泡状，而且因为油量较多在该处形成过多的残留物而影响使用。油污缺陷多少是评价铝箔质量的一项很紧张指标。  铝卷贩卖 解决方法：在生产曩昔严酷检查生产设备，假如一旦发现设备中油污过多要及时清洗并且查找缘故原由，同时对生产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。
This oil stain will do great harm to the surface of aluminum coil: first, because most of the finished products of aluminum coil as decorative or packaging materials, must have a clean surface; second, because of its thin thickness, it is easy to form bubbles in subsequent annealing, and because the amount of oil is too much residue in the place and affect the use. The number of oil pollution defects is a very important index to evaluate the quality of aluminum foil. Solution for sale of aluminium coil: Strictly check the production equipment before production, if it is found that there is too much oil stain in the equipment to clean and find out the reason in time, and at the same time to clean the production products, if the product can not be washed off for scrap treatment, oil stained products are prohibited from storage and into the market.
铝卷 邃密加工件在前处理工序中必要细致的题目：邃密加工件虽然外观的天然氧化膜才初生成，较易消灭，但油腻重，分外是孔眼内及其四周百度seo，这类工件必须先经有机溶剂清洗，若直接用碱洗不但油腻重难以除净，且邃密加工面承受不了长时间的强碱腐蚀，效果还会影响到工件外观的粗糙程度和公差的配合，最终有可能成为废品。
Some problems should be paid attention to in the pretreatment process of aluminum coil fine workpiece: although the natural oxide film on the surface of the fine workpiece is just formed and easy to remove, the greasy workpiece, especially in and around the hole, must be cleaned by organic solvent first. If the workpiece is washed directly with alkali, it is difficult to remove the greasy and heavy workpiece, and fine processing. Surface can not withstand long-term strong alkali corrosion, the result will also affect the roughness of the workpiece surface and tolerance of the fit, and may eventually become waste.
