鋁加工產品給生活帶來便利,鋁卷就是其主要代表產品之一,但我們在日常使用中偶爾也會遇到一些問題,那么用戶購買時應觀察鋁卷是否出現什么問題?鋁卷生產廠家為你詳細解讀。
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:非金屬碎屑壓在板和帶的表面上。表面呈長條狀明顯點狀或黃黑色缺陷。
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滑動或錯位而形成的劃痕
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過程中,板帶與導軌和設備接觸時,會產生相對摩擦和劃痕。冷軋卷板端面未對齊,豎爐退火和翻轉造成錯位和層間干擾。間歇性劃痕,冷軋時張力不當,退火時層間錯位,都會造成劃痕。不適當的整理批準或攤鋪操作會導致板間滑動和劃痕。
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:搬運或在存放過程中,板材或線圈與其他物體發生碰撞,板材或線圈與退火架或底盤中的其他物體發生碰撞。
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:軋制時壓下量過大,軋制時潤滑劑分布不均,剪切時刃口調整不當。
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:彎曲板材后產生的變形折疊。
Definition: deformation folding after bending sheet.
主要原因:多輥矯直機送料不正,薄板受到翻轉折疊。堆疊紙張時受力不平衡。
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,鐵芯強度低,壓接過程中無鐵芯線圈退火產生。
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則運動而導致帶鋼端面不平整。
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、軋機放卷和卷取張力控制不當、壓下量和套筒移動不均勻、校平輥調整不當、卷取過程中對中系統異常、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.
