近年来，我国经济快速发展，航空航天、装饰材料及饮料等行业对铝带、铝箔的需求不断增加，给PS基材、铝塑带、罐头材料等高精度铝板带材带来了快速的发展。这些产品平面度、清洁度要求非常严格,和高精度铝条通常是用于整个油冷却和润滑轧制、表面的大量轧制油和铝粉,为了获得良好的表面质量,必须清洗去除表面残留。除了平面度要求铝带和高拉伸弯曲矫直,拉伸弯曲矫直带材在二级和弯曲的作用下,逐渐产生塑料薄膜释放内应力,改善板带钢生产在寒冷的工作波形,翘曲,横向弯曲,和潜在板形不良等缺陷,考虑矫直过程中,必须进行表面清洗。
　　In recent years, China's rapid economic development, aerospace, decorative materials and beverages and other industries on the increasing demand for aluminum strip, aluminum foil, PS substrate, aluminum plastic tape, canned materials and other high-precision aluminum sheet and strip has brought rapid development. These products require very strict flatness and cleanliness, and high-precision aluminium bars are usually used for oil cooling and lubrication rolling, a large number of rolling oils and aluminium powder on the surface. In order to obtain good surface quality, it is necessary to clean and remove surface residues. In addition to flatness requirements for aluminum strip and high-tension bending straightening, tension-bending straightening strip gradually produces plastic film ZhongBing releasing internal stress under the effect of secondary and bending, and improves the defects of cold working waveform, warpage, transverse bending, and potential bad shape of strip steel. Considering the straightening process, surface must be carried out first. Clean.

　　Principle and Theory of Aluminum Strip Cleaning

　　在冷轧过程中,由于辊之间的摩擦和轧制铝板的表面,表面会产生细氧化铝粉末吸附,轧制油和悬浮组件仍将在铝板的表面,这将影响复合、涂层和其他成品加工。矫直时,由于暴力弯曲变形的带辊、张力应用于带的一部分转化为带钢在张力辊的压力,较后,摩擦力驱动辊形成集。因此,如果带的表面不清洁,氧化铝粉末脱落变形期间,x将附着在表面的张力辊和油脂,造成滚筒表面磨损，对铝板有轻微损伤。因此，它必须通过一个特殊的清洗设备清洗。清洗是用压力泵增压清洗介质,非接触式喷淋洗涤或接触表面刷地带,所以铝粉表面的石油放荡和脱落进入清洗介质,然后通过挤压辊挤压和高压空气吹,即使高温空气干燥,为了获得清洁和干燥的铝条。同时，通过清洗介质和在线循环过滤系统的不断补充，使清洗介质保持足够的清洁，大大节约了热能和清洗介质。目前，铝加工行业常用的清洗介质是清洗剂(或溶剂油)、软化热水、化学溶剂，各有优缺点。
　　In the cold rolling process, fine alumina powder adsorbed on the surface of rolls and rolled aluminium sheet will be produced, and the rolling oil and suspension components will remain on the surface of aluminium sheet, which will affect the processing of composite, coating and other finished products. In straightening, the tension applied to a part of the strip is transformed into the pressure of the strip on the tension roll due to the violent bending deformation. Finally, the friction driving rolls form a set. Therefore, if the surface of the strip is not clean, during the alumina powder shedding deformation, x will adhere to the surface tension roll and grease, resulting in surface wear of the drum and slight damage to the aluminium plate. Therefore, it must be cleaned by a special cleaning equipment. Cleaning is a pressure pump pressurized cleaning medium, non-contact spray washing or contact surface brushing zone, so the oil on the surface of aluminium powder dissolves and falls off into the cleaning medium, and then through extrusion roll extrusion and high-pressure air blowing, even if high-temperature air drying, in order to obtain clean and dry aluminium bars. At the same time, through the continuous supplement of cleaning medium and online circulating filtration system, the cleaning medium can be kept clean enough, and the heat energy and cleaning medium can be saved greatly. At present, the commonly used cleaning media in aluminium processing industry are cleaning agent (or solvent oil), softening hot water and chemical solvent, each of which has its advantages and disadvantages.
　　下面采用高压水射流技术对清洗系统进行阐述。
　　Next, the high pressure water jet technology is used to describe the cleaning system.
　　高压水射流的射流距离是由密集射流束的直接喷射产生的，产生巨大的冲击力。射流束与喷嘴中心线对称布置，但存在发散，射流一般分为三段。原始截面的长度用l表示。射流这一截面的特点是沿轴向的动压力值几乎是恒定的，射流尖端的动压力与喷嘴出口的动压力相同。另一个特点是非常密集的质地、质量与空气混合,这较强的力量,它主要用于清洁硬垢,基本部分,长度和楼主说,飞机的特点是与水射流混合空气开始,孔和涡流,这力量是温和,适合各种清洗设备和材料。需要指出的是，随着距离的增加，有效打击力也逐渐减小。散度段的长度用L3表示，其特征是气水射流完全混合，射流完全雾化，冲击压力和射流速度显著下降。从技术上讲，jet的这一部分没有应用价值。水射流清洗的应用，关键在于压力和流量的选择与匹配。然而，在不同的射流距离和扩散角下，直接起作用的压力和流量是不同的。
　　The jet distance of high pressure water jet is produced by direct injection of dense jet beam, which produces huge impact force. The jet beam is symmetrically arranged with the central line of the nozzle, but divergence exists. The jet is generally divided into three sections. The length of the original section is expressed in L. The characteristic of the jet section is that the dynamic pressure along the axis is almost constant, and the dynamic pressure at the jet tip is the same as that at the nozzle exit. Another feature is very dense texture, mass and air mixing, which is the strongest force. It is mainly used to clean hard dirt, basic parts, length and building owner said that the aircraft is characterized by mixing air with water jet, holes and eddies, which is mild, suitable for various cleaning equipment and materials. It should be pointed out that with the increase of distance, the effective hitting force also decreases gradually. The length of divergence section is expressed by L3, which is characterized by complete mixing of air-water jet, complete atomization of jet, and significant decrease of impact pressure and jet velocity. Technically, this part of Jet has no application value. The key to the application of water jet cleaning lies in the selection and matching of pressure and flow rate. However, under different jet distances and diffusion angles, the pressure and flow rate acting directly are different.
