      清洗步驟對于鋁卷生產的有什么作用?

      鋁卷在冷軋制過程中,因軋輥與鋁板表面摩擦和碾壓,其表面會產生細微的氧化鋁粉脫落和吸附,軋制油及其附帶懸浮成分會殘留在鋁卷表面,對鋁卷復合、涂裝等成品加工造成不利影響。
      During the cold rolling process of aluminum coil, due to the friction and rolling of roll and aluminum plate surface, fine aluminum oxide powder will fall off and adsorb on its surface, and rolling oil and its attached suspended components will remain on the surface of aluminum coil, which will have an adverse impact on the processing of aluminum coil composite, coating and other finished products.
      拉彎矯直時由于帶材在輥上產生劇烈彎曲變形,對帶材施加的張力一部分轉化為帶材對張力輥的壓力,并形成摩擦力,帶動輥組。如果氧化鋁卷表面未經清洗,變形時氧化鋁粉脫落,隨著油污一起附在張力輥的輥面,使輥面產生磨損,并造成鋁板略傷,故必須通過專門的清洗裝置進行清洗。
      During tension bending and straightening, due to the severe bending deformation of the strip on the roll, part of the tension applied to the strip is transformed into the pressure of the strip on the tension roll, forming friction and driving the roll group. If the surface of the alumina roll is not cleaned, the aluminum oxide powder falls off during deformation and is attached to the roll surface of the tension roll along with the oil stain, resulting in wear on the roll surface and slight injury to the aluminum plate, so it must be cleaned by a special cleaning device.

      鋁卷清洗就是利用壓力泵對清洗介質加壓,對帶材表面進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中,再經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 and carry out non-contact spray cleaning or contact brushing on the strip surface, so that the aluminum powder oil on the material surface dissolves and falls off into the cleaning medium, and then is squeezed by the squeezing roller, purged by high-pressure air, and even dried by high-temperature air, so as to obtain clean and dry aluminum coil.
      同時,通過不斷補充清洗介質與在線循環過濾系統同時使用,使清洗介質保持足量和清潔,并大大節約熱能和清洗介質。目前,鋁卷加工行業的拉彎矯直機常用的清洗介質有清洗劑(或稱溶劑油)、軟化熱水、化學溶劑。
      At the same time, by continuously replenishing the cleaning medium and using the on-line 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, the commonly used cleaning media of stretch bending straightener in aluminum coil processing industry include cleaning agent (or solvent oil), softened hot water and chemical solvent.
