鋁卷在冷軋制過(guò)程中，因軋輥與鋁板表面摩擦和碾壓，其表面會(huì)產(chǎn)生細(xì)微的氧化鋁粉脫落和吸附，軋制油及其附帶懸浮成分會(huì)殘留在鋁卷表面，對(duì)鋁卷復(fù)合、涂裝等成品加工造成不利影響。
In the cold rolling process of aluminum coil, due to the friction and rolling between the roll and the surface of aluminum plate, fine aluminum oxide powder will fall off and adsorb on the surface. The rolling oil and its attached suspended components will remain on the surface of aluminum coil, which has adverse effects on the processing of aluminum coil composite, coating and other finished products.
拉彎矯直時(shí)由于帶材在輥上產(chǎn)生劇烈彎曲變形，對(duì)帶材施加的張力一部分轉(zhuǎn)化為帶材對(duì)張力輥的壓力，并終形成摩擦力，帶動(dòng)輥組。如果氧化鋁卷表面未經(jīng)清洗，變形時(shí)氧化鋁粉脫落，隨著油污一起附在張力輥的輥面，使輥面產(chǎn)生磨損，并造成鋁板略傷，故必須通過(guò)專門的清洗裝置進(jìn)行清洗。
During stretch bending straightening, due to the severe bending deformation of the strip on the roll, a part of the tension applied to the strip is transformed into the pressure of the strip on the tension roll, and finally the friction force is formed to drive the roll group. If the surface of aluminum oxide coil is not cleaned, the aluminum oxide powder will fall off when it is deformed and attach to the roll surface of tension roll with oil stain, which will cause wear on the roll surface and slightly damage the aluminum plate. Therefore, it must be cleaned by special cleaning device.

鋁卷清洗就是利用壓力泵對(duì)清洗介質(zhì)加壓，對(duì)帶材表面進(jìn)行非接觸式噴洗或接觸式刷洗，使材料表面的鋁粉油污溶解脫落到清洗介質(zhì)中，再經(jīng)擠干輥擠干和高壓空氣吹掃，甚至高溫空氣烘干，以獲得潔凈干燥的鋁卷。
Aluminum coil cleaning is to use the pressure pump to pressurize the cleaning medium, non-contact spray or contact brushing on the surface of the strip, so that the aluminum powder oil on the surface of the material dissolves and falls off into the cleaning medium, and then the aluminum coil is dried by squeezing roller, high-pressure air blowing, and even high-temperature air drying, so as to obtain clean and dry aluminum coil.
同時(shí)，通過(guò)不斷補(bǔ)充清洗介質(zhì)與在線循環(huán)過(guò)濾系統(tǒng)同時(shí)使用，使清洗介質(zhì)保持足量和清潔，并大大節(jié)約熱能和清洗介質(zhì)。目前，鋁卷加工行業(yè)的拉彎矯直機(jī)常用的清洗介質(zhì)有清洗劑（或稱溶劑油）、軟化熱水、化學(xué)溶劑。
At the same time, by continuously replenishing the cleaning medium and using the online circulating filtration system at the same time, the cleaning medium can be kept sufficient and clean, and the heat energy and cleaning medium can be greatly saved. At present, cleaning agents (or solvent oil), softened hot water and chemical solvents are commonly used in the straightening machine of aluminum coil processing industry.
