高壓清洗機在鋁板帶清洗設(shè)備上的應(yīng)用近年來跟著我國國民經(jīng)濟的高速開展,航空航天、家用電器、裝飾材料及飲料行業(yè)等對鋁帶、箔的需求越來越大,帶來了PS基材、鋁塑帶、電容器箔、制罐料等高精度鋁板帶材的快速開展。
In recent years, the application of high-pressure cleaner in the cleaning equipment of aluminium sheet and strip has been developing at a high speed in our national economy. The demand for aluminium strip and foil is increasing in aerospace, household appliances, decorative materials and beverage industries. It has brought the rapid development of PS base material, aluminium plastic strip, capacitor foil, canning material and other high-precision aluminium sheet and strip.
這些產(chǎn)品對平直度、潔凈度要求十分嚴(yán)格,而高精度鋁帶材通常是選用全油冷卻光滑軋制的,其外表殘留很多的軋制油和鋁粉,因而要取得良好的外表質(zhì)量,有必要清洗去掉其外表殘留物。
These products have strict requirements for flatness and cleanliness. High-precision aluminium strips are usually rolled with oil cooling and smooth rolling. There are a lot of rolling oil and aluminium powder remaining on their surface. Therefore, in order to achieve good surface quality, it is necessary to clean and remove the surface residues.
另外關(guān)于板形要求較高鋁帶材還要進(jìn)行拉彎矯直,拉彎矯直使帶材在拉仲和曲折的作用下,逐漸發(fā)生塑性延仲并開釋板材內(nèi)應(yīng)力,以改善板帶材在冷加工時發(fā)生的波形、翹曲、側(cè)彎和潛在的板形不良等缺點,從矯直工藝考慮,有必要對帶材外表進(jìn)行清洗。
In addition, STRETCH-BEND straightening is also necessary for aluminum strips with higher shape requirements. Under the effect of STRETCH-BEND straightening, plastic extension and internal stress release gradually occur to improve the defects of waveform, warpage, lateral bending and potential bad shape during cold processing. Considering straightening process, it is necessary to clean the outer surface of strips first.
鋁板帶清洗原理及理論
Cleaning Principle and Theory of Aluminum Plate and Strip
清洗原理鋁板帶在冷軋制過程中,因軋輥與鋁板外表摩擦和碾壓,其外表會發(fā)生纖細(xì)的氧化鋁粉脫落和吸附,軋制油及其順便懸浮成分會殘留在鋁板外表,對鋁板帶復(fù)合、涂裝等成品加工形成不利影響。而目_拉彎矯直時由于帶材在輥上發(fā)生劇烈曲折變形,對帶材施加的張力一部分轉(zhuǎn)化為帶材對張力輥的壓力,并終究構(gòu)成摩擦力,帶動輥組。
Cleaning Principle Aluminum plate and strip in cold rolling process, because of friction and rolling between roll and aluminium plate, fine alumina powder will fall off and adsorb on its surface. Rolling oil and its suspended components will remain on the surface of aluminium plate and strip, which will adversely affect the processing of finished products such as aluminium plate and strip compounding and coating. The tension exerted on the strip is partly transformed into the tension roll pressure of the strip due to the severe bending deformation of the strip on the roll, and eventually constitutes the friction force, which drives the roll group.
因而,假如帶材外表未經(jīng)清洗,變形時氧化鋁粉脫落,跟著油污一起x附在張力輥的輥面,使輥面發(fā)生磨損,并形成鋁板略傷,故有必要經(jīng)過專門的清洗設(shè)備進(jìn)行清洗。
Therefore, if the strip surface is not cleaned and alumina powder falls off during deformation, X is attached to the roll surface of tension roll with oil pollution, which causes wear and tear of roll surface and slight damage of aluminium plate. Therefore, it is necessary to clean by special cleaning equipment.
清洗就是運用壓力泵對清洗介質(zhì)加壓,對帶材外表進(jìn)行非接觸式噴洗或接觸式刷洗,使材料外表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,乃至高溫空氣烘干,以取得潔凈干燥的鋁帶材。
Cleaning is to use pressure pump to pressurize the cleaning medium, to spray or brush the surface of the strip in a non-contact way, so that the oil pollution of the aluminum powder on the surface of the material can dissolve and fall off into the cleaning medium, and then be extruded by the extrusion roller, cleaned by high-pressure air, or even dried by high-temperature air, in order to obtain clean and dry aluminum strip.
一起,經(jīng)過不斷彌補清洗介質(zhì)與在線循環(huán)過濾系統(tǒng)一起運用,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,鋁加工行業(yè)的拉彎矯直機常用的清洗介質(zhì)有清洗劑(或稱溶劑油)、軟化熱水、化學(xué)溶劑,并各有優(yōu)缺點。
Together, the cleaning medium is continuously compensated and used together with the online circulating filtration system to keep the cleaning medium in sufficient quantity and clean, and greatly save heat and cleaning medium. At present, the commonly used cleaning media of STRETCH-BEND Leveller in aluminum processing industry are cleaning agent (or solvent oil), softening hot water and chemical solvent, and each has its own advantages and disadvantages.
