高压水清洗在铝板带上的使用特点

来源:

高压清洗机在铝板带清洗设备上的应用近年来随着我国国民经济的高速发展,航空航天、家用电器、装饰材料及饮料行业等对铝带、箔的需求越来越大,带来了PS基材、铝塑带、电容器箔、制罐料等高精度铝板带材的快速发展。这些产品对平直度、洁净度要求非常严格,而高精度铝带材通常是采用全油冷却润滑轧制的,其表面残留大量的轧制油和铝粉,因此要获得良好的表面质量,必须清洗去掉其表面残留物。
In recent years, with the rapid development of China's national economy, the demand for aluminum strip and foil in aerospace, household appliances, decorative materials and beverage industry is increasing, which brings the rapid development of PS substrate, aluminum plastic strip, capacitor foil, canning material and other high-precision aluminum strip. These products require very strict flatness and cleanliness, and high-precision aluminum strips are usually rolled by oil cooling and lubrication. There are a lot of rolling oil and aluminum powder on the surface of the strips. Therefore, in order to obtain good surface quality, the surface residue must be cleaned out.
另外对于板形要求较高铝带材还要进行拉弯矫直,拉弯矫直使带材在拉仲和弯曲的作用下,逐步产生塑性延仲并释放板材内应力,以改善板带材在冷加工时产生的波形、翘曲、侧弯和潜在的板形不良等缺陷,从矫直工艺考虑,首先必须对带材表面进行清洗。
In order to improve the waveform, warpage, lateral bending and potential flatness defect of aluminum strip during cold working, stretching and bending straightening should be carried out. First, the surface of the strip must be cleaned.
铝板带清洗原理及理论

清洗原理铝板带在冷轧制过程中,因轧辊与铝板表面摩擦和碾压,其表面会产生细微的氧化铝粉脱落和吸附,轧制油及其附带悬浮成分会残留在铝板表面,对铝板带复合、涂装等成品加工造成不利影响。而目_拉弯矫直时由于带材在辊上产生剧烈弯曲变形,对带材施加的张力一部分转化为带材对张力辊的压力,并最终形成摩擦力,带动辊组。
Cleaning Principle Aluminum strip in cold rolling process, because the roller and the surface of aluminum plate friction and rolling, its surface will produce fine aluminum oxide powder shedding and adsorption, rolling oil and its associated suspension components will remain on the surface of aluminum plate, aluminum plate and strip composite, coating and other products processing adverse effects. However, due to the sharp bending deion 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, and finally the friction force is formed to drive the roll group.
因此,如果带材表面未经清洗,变形时氧化铝粉脱落,随着油污一起x附在张力辊的辊面,使辊面产生磨损,并造成铝板略伤,故必须通过专门的清洗装置进行清洗。清洗就是利用压力泵对清洗介质加压,对带材表面进行非接触式喷洗或接触式刷洗,使材料表面的铝粉油污溶解脱落到清洗介质中,再经挤干辊挤干和高压空气吹扫,甚至高温空气烘干,以获得洁净干燥的铝带材。同时,通过不断补充清洗介质与在线循环过滤系统同时使用,使清洗介质保持足量和清洁,并大大节约热能和清洗介质。目前,铝加工行业的拉弯矫直机常用的清洗介质有清洗剂(或称溶剂油)、软化热水、化学溶剂,并各有优缺点。
Therefore, if the surface of the strip is not cleaned, the alumina powder will fall off when it is deformed, and X will be attached to the surface of the tension roll along with the oil stain, which will cause wear and tear on the surface of the roll and cause slight damage to the aluminum plate, so it must be cleaned by a special cleaning device. Cleaning is to use the pressure pump to pressurize the cleaning medium, non-contact spray cleaning or contact cleaning of the strip surface, so that the surface of the material aluminum powder oil dissolved off to the cleaning medium, and then extruded by the extrusion roller drying and high-pressure air blowing, or even high-temperature air drying, in order to obtain clean and dry aluminum strip. At the same time, by continuously supplementing the cleaning medium and using the online circulating filter system simultaneously, the cleaning medium can be kept adequate and clean, and the heat energy and the cleaning medium can be greatly saved. At present, the cleaning commonly used in stretch-bending straighteners in aluminum processing industry are cleaning agents (or solvent oil), softening hot water, chemical solvents, and each has its advantages and disadvantages.
高压水射流的喷射距离高压水射流是靠密实的流束直接喷射而产生巨大的打击力,密实射流和直接喷射二者缺一不可。射流流束以喷嘴中心线呈对称布置,而是发散分布,射流一般分为三段。原始段,长度用L,表示,这段射流的特点是沿轴向的动压力值儿乎是常数,射流尖端的动压和喷嘴出口的动压是相同的。另一特点质地非常密实,质点儿乎不和空气相混和,因此该段的打击力最强,主要用于清洗坚硬的结垢物,基本段,长度用Lz表示,这段射流的特点是空气开始与水射流相混合,形成了空穴和涡流,因此该段的打击力适中,适合各种设备及物料的清洗。
The distance between high-pressure water jet and high-pressure water jet is the direct injection of dense beams, which produces tremendous impact force. The jet flow is symmetrical in the center line of the nozzle, but diverges and distributes. The jet is generally divided into three segments. The original section, length expressed in L, is characterized by a constant axial dynamic pressure, and the dynamic pressure at the tip of the jet is the same as that at the nozzle exit. Another feature is that the texture is very dense and the particles are hardly compatible with the air, so this section is the strongest hit, mainly used to clean the hard dirt, the basic section, length expressed in Lz, this section of jet is characterized by air and water jet mixing, forming cavities and eddies, so the impact of this section is moderate, suitable for Cleaning of various equipment and materials.
