For aluminum strip slitting, quality inspectors should pay close attention to whether there are scratches during the equipment winding process. If there are foreign objects inside the equipment during the slitting process, it can cause scratches with a straight grain size and trend from beginning to end, which has a significant impact on surface quality. Therefore, attention should be paid to scratches during the winding process. If scratches are found, production should be stopped immediately and the cause should be found.
Usually, scratches on aluminum strips occur during the slitting process, and there are fewer issues with the masterbatch. Therefore, slitting employees should inspect and clean foreign objects on the production line before processing, pay attention to the surface of the aluminum strip during production, and observe whether there are scratches on the surface of the aluminum strip during packaging. At the same time, if there are scratches on the masterbatch in the province, production should be stopped in a timely manner and reported in a timely manner. The aluminum strip used for transformers is cut without burrs, and the surface of the finished product is smooth and scratch free. The plate shape is flat, and the cross-section is neat. After chamfering, rounded corners and zero burrs are achieved. The processed aluminum strip should not produce any new surface defects (such as scratches, transverse vibration lines left by the straightening machine, etc.) Note: Replace and clean the surface of each unit in a timely manner after anti scratch treatment.

铝带外表损伤主要原因 ：铸锭内存在一定数量的坚硬的金属颗粒，①铸锭外表附着有杂物或铸锭成分偏析。铸锭表面存在大量偏析浮出物而铸锭又未进行均匀化处置或均匀化处置效果不好时。挤压过程中金属流经工作带时，这些偏析浮出物或坚硬的金属颗粒附着在工作带外表或对工作带造成损伤，最终对铝带外表造成划伤； ②工作带上有杂物，使工作带表面在挤压时受伤而划伤铝带； 当其与铝带接触时对铝带外表造成划伤；③出料轨道或摆床上有裸露的金属或石墨条内有较硬的夹杂物。 由于速度过快造成铝带碰伤；④在叉料杆将铝带从出料轨道上送到摆床上时。 ⑤在摆床上人为拖动铝带造成擦伤； ⑥在运输过程中铝带之间相互摩擦或挤压造成损伤。
The main cause of surface damage to aluminum strips is the presence of a certain amount of hard metal particles inside the ingot, ① debris or segregation of ingot components attached to the surface of the ingot. When there is a large amount of segregation floating on the surface of the ingot and the ingot has not been homogenized or the homogenization treatment effect is not good. During the extrusion process, when the metal flows through the working strip, these segregation floats or hard metal particles adhere to the surface of the working strip or cause damage to the working strip, ultimately causing scratches on the surface of the aluminum strip; ② There are debris on the work belt, causing the surface of the work belt to be injured during compression and scratching the aluminum strip; When it comes into contact with the aluminum strip, it causes scratches on the surface of the aluminum strip; ③ There are exposed metal or graphite strips with hard inclusions on the discharge track or bed. The aluminum strip is damaged due to excessive speed; ④ When the aluminum strip is transported from the discharge track to the swing bed by the fork rod. ⑤ Scratches caused by manually dragging the aluminum strip on the bed; ⑥ Damage caused by mutual friction or compression between aluminum strips during transportation.
解决方法 ：加强对铸锭质量的控制； 尽量减少铝带与辅具的接触损伤。③用软质毛毡将铝带与辅具隔离。 尽量防止随意拖动或翻动铝带，及时清理毛毡上面的异物。④生产中要轻拿轻放。 尽量防止相互摩擦。⑤在料框中合理摆放铝带。
Solution: Strengthen the control of ingot quality; Minimize contact damage between aluminum strips and accessories as much as possible. ③ Use soft felt to isolate the aluminum strip from the accessory. Try to prevent arbitrary dragging or flipping of the aluminum strip, and clean foreign objects on the felt in a timely manner. ④ Handle with care during production. Try to prevent mutual friction. ⑤ Reasonably place aluminum strips in the material frame.
