在5052鋁板的生產(chǎn)或運(yùn)輸中，由于操作不當(dāng)，會出現(xiàn)各種缺陷，這些缺陷的存在會影響鋁板的性能，嚴(yán)重的缺陷甚至?xí)?dǎo)致鋁板報(bào)廢，給客戶和廠家造成嚴(yán)重的經(jīng)濟(jì)損失。下面，我們將了解鋁板缺陷的類型及原因，希望您多多關(guān)注。鋁板的缺陷可分為板型、尺寸和表面質(zhì)量三類。
　　In the production or transportation of 5052 aluminium sheet, due to improper operation, there will be various defects, which will affect the performance of aluminium sheet. Serious defects will even lead to scrap of aluminium sheet, causing serious economic losses to customers and manufacturers. Next, we will understand the types and causes of defects in aluminium sheets. I hope you will pay more attention to them. Defects of aluminium sheet can be divided into three categories: plate type, size and surface quality.
　　一、板類型
　　I. Plate Type
　　1. 波。主要原因如下:1。(2)潤滑冷卻不均勻，使印版變形不均勻;(3)壓力分布不合理;(4)進(jìn)板型式不良;5. 卷繞張力使用不均勻。
　　1. Wave. The main reasons are as follows: 1. (2) Non-uniform lubrication and cooling, resulting in non-uniform plate deformation; (3) unreasonable pressure distribution; (4) bad feed pattern; and (5) uneven use of winding tension.
　　2. 交錯(cuò)層:帶鋼端面層間不規(guī)則錯(cuò)位，導(dǎo)致端面不均勻。原因:不均勻的空白;軋機(jī)卷取張力控制不當(dāng);壓輥調(diào)整不當(dāng)。
　　2. Interlaced layer: irregular misalignment between layers of strip end surface leads to uneven end surface. Reasons: uneven blank; improper coiling tension control of rolling mill; improper roll adjustment.
　　3.塌輥:輥芯變形嚴(yán)重，輥型不圓。原因:卷曲時(shí)張力不當(dāng);外部力量正在施加壓力。
　　3. Collapse roll: The roll core is seriously deformed and the roll shape is not round. Reason: The tension is inappropriate when curling; external forces are exerting pressure.
　　4. 橫向彎曲:表現(xiàn)為板向一側(cè)彎曲。原因:找平機(jī)壓力不夠。
　　4. Transverse bending: It shows that the plate bends to one side. Reason: The pressure of leveller is not enough.
　　第二,大小
　　Second, size

　　缺陷的尺寸主要體現(xiàn)在鋁板厚度/寬度/長度的誤差范圍內(nèi)。厚度計(jì)、圓盤剪切機(jī)、剪切機(jī)調(diào)整。
　　The size of defect is mainly reflected in the error range of thickness/width/length of aluminium sheet. Thickness gauge, disc shearing machine, shearing machine adjustment.
　　更高的位置!5052鋁板的缺陷較初就是由這個(gè)原因造成的
　　Higher position! The defect of 5052 aluminium plate was originally caused by this reason.
　　三世。表面質(zhì)量
　　King III. surface quality
　　1. 壓花。軋輥表面的不規(guī)則色差是由帶鋼的折裂引起的。
　　1. Embossing. The irregular color difference on the roll surface is caused by the fracture of strip steel.
　　2. 邊緣翹曲。主要原因:(1)滾壓過緊;(2)軋制油分布不均勻;(3)剪刃調(diào)整不當(dāng)。
　　2. Edge warping. The main reasons are: (1) too tight rolling; (2) uneven distribution of rolling oil; (3) improper adjustment of cutting edge.
　　3、鋁板表面性能成束分布疤痕。原因:機(jī)械或手工造成鋁板層間錯(cuò)位
　　3. The surface properties of aluminium sheet distribute scars in bunches. Cause: mechanical or manual interlaminar dislocation of aluminium sheet
　　4. 鋁板表面有線狀分布的疤痕。原因:導(dǎo)板或平滾凸鋁或粘鋁;剪切時(shí)產(chǎn)生劃痕;人工檢查吊裝不當(dāng)。
　　4. There are linear scars on the surface of aluminium plate. Reasons: guide plate or flat rolling convex aluminium or sticky aluminium; scratches when shearing; improper manual inspection and hoisting.
　　5. 石油污染:表面很臟。原因:冷卻油不干凈，吹氣不良。
　　5. Oil pollution: The surface is dirty. Reasons: Cooling oil is not clean and bad blowing.
　　6. 彎曲的一面。主要原因:(1)軋機(jī)兩端落料量不相同;2軋機(jī)進(jìn)給誤差;(3)板材、帶料兩側(cè)厚度不一致;(4)輥筒預(yù)熱或乳化液流動控制不當(dāng);(5)工藝潤滑油濃度過高，導(dǎo)致打滑;6 .剪切前波存在，剪切后波存在。
　　6. The curved side. The main reasons are: (1) different blanking amount at both ends of the mill; 2) feed error of the mill; (3) different thickness of sheet and strip; (4) improper control of roll preheating or emulsifying fluid flow; (5) excessive concentration of process lubricant leading to slippage; and (6) existence of pre-shear wave and post-shear wave.

　　Higher position! The defect of 5052 aluminium plate was originally caused by this reason.
　　面對這些可能存在的缺陷，鋁板生產(chǎn)廠家需要做的就是嚴(yán)格控制生產(chǎn)工藝，層層把關(guān)，精心包裝，安全運(yùn)輸。減少對鋁板的損壞，保證鋁板的質(zhì)量。想要了解更多內(nèi)容，歡迎訪問網(wǎng)站：http://www.liyukeji.com
　　Faced with these possible defects, aluminum plate manufacturers need to strictly control the production process, layers of checks, careful packaging, safe transportation. Reduce the damage to the aluminium sheet and ensure the quality of the aluminium sheet. For more information, please visit the website: http://www.liyukeji.com.
