Aluminum processing products bring convenience to life, and aluminum coil is one of its main representative products. However, we occasionally encounter some problems in daily use, so users should observe whether there are any problems with aluminum coil when purchasing? The aluminum coil manufacturer will give you a detailed explanation.
1、非金屬壓痕
1. Nonmetallic indentation
定義：非金屬碎屑?jí)涸诎搴蛶У谋砻嫔?。表面呈長條狀明顯點(diǎn)狀或黃黑色缺陷。
Definition: Non metallic chips press on the surface of plates and strips. The surface presents long strip shaped obvious spot shaped or yellow black defects.
主要原因是軋制工藝設(shè)備條件臟、軋制工藝潤滑劑臟、工藝潤滑劑注射壓力不足、板坯表面有劃痕。
The main reasons are that the rolling process equipment conditions are dirty, the rolling process lubricant is dirty, the injection pressure of the process lubricant is insufficient, and the slab surface has scratches.
2、滑傷
2. Slip injury
定義：由于邊緣與表面或表面與表面接觸之間的相對(duì)滑動(dòng)或錯(cuò)位而形成的劃痕
Definition: scratches caused by relative sliding or dislocation between edges and surfaces or between surfaces
主要原因：鋁卷廠家在加工和生產(chǎn)過程中，板帶與導(dǎo)軌和設(shè)備接觸時(shí)，會(huì)產(chǎn)生相對(duì)摩擦和劃痕。冷軋卷板端面未對(duì)齊，豎爐退火和翻轉(zhuǎn)造成錯(cuò)位和層間干擾。間歇性劃痕，冷軋時(shí)張力不當(dāng)，退火時(shí)層間錯(cuò)位，都會(huì)造成劃痕。不適當(dāng)?shù)恼砼鷾?zhǔn)或攤鋪操作會(huì)導(dǎo)致板間滑動(dòng)和劃痕。
Main reason: In the processing and production process of aluminum coil manufacturers, when the strip contacts with the guide rail and equipment, there will be relative friction and scratches. The end faces of cold rolled coils are not aligned, and shaft furnace annealing and overturning cause dislocation and interlayer interference. Intermittent scratches, improper tension during cold rolling and dislocation between layers during annealing will all cause scratches. Improper finishing approval or paving operations can cause slippage and scratches between plates.
3、碰傷
3. Bruise
定義：鋁板或鋁卷與另一物體碰撞后，板或帶的表面或端面被劃傷，大部分金屬從凹槽邊緣突出。
Definition: After the aluminum plate or aluminum coil collides with another object, the surface or end face of the plate or strip is scratched, and most of the metal protrudes from the edge of the groove.
主要原因：搬運(yùn)或在存放過程中，板材或線圈與其他物體發(fā)生碰撞，板材或線圈與退火架或底盤中的其他物體發(fā)生碰撞。
Main reasons: during handling or storage, plates or coils collide with other objects, and plates or coils collide with other objects in the annealing rack or chassis.
4、翹角
4. Warping angle
定義：帶鋼邊緣在軋制或剪切后被抬起。
Definition: The edge of strip steel is lifted after rolling or shearing.
主要原因：軋制時(shí)壓下量過大，軋制時(shí)潤滑劑分布不均，剪切時(shí)刃口調(diào)整不當(dāng)。
Main reasons: excessive reduction during rolling, uneven distribution of lubricant during rolling, improper adjustment of cutting edge during shearing.

5、折傷
5. Kink wound
定義：彎曲板材后產(chǎn)生的變形折疊。
Definition: deformation folding after bending sheet.
主要原因：多輥矯直機(jī)送料不正，薄板受到翻轉(zhuǎn)折疊。堆疊紙張時(shí)受力不平衡。
Main reasons: the feeding of the multi roll straightener is not correct, and the sheet is overturned and folded. The force is unbalanced when stacking paper.
6、塌卷
6. Collapse roll
定義：卷芯嚴(yán)重變形，卷形不圓。
Definition: The winding core is seriously deformed and the winding shape is not round.
主要原因：張力不足，外壓，鐵芯強(qiáng)度低，壓接過程中無鐵芯線圈退火產(chǎn)生。
Main reasons: insufficient tension, external pressure, low iron core strength, no iron core coil annealing during crimping.
7分層
7 Tiering
定義：由于層與端面層之間的不規(guī)則運(yùn)動(dòng)而導(dǎo)致帶鋼端面不平整。
Definition: The end surface of strip steel is uneven due to the irregular movement between layers and end layers.
主要原因有鋼坯不均勻、軋機(jī)放卷和卷取張力控制不當(dāng)、壓下量和套筒移動(dòng)不均勻、校平輥調(diào)整不當(dāng)、卷取過程中對(duì)中系統(tǒng)異常、輥系平整度差等。
The main reasons are uneven billet, improper tension control of rolling mill unwinding and coiling, uneven reduction and sleeve movement, improper adjustment of leveling roll, abnormal centering system during coiling, poor flatness of roll system, etc.
