Pay attention to safety when cutting aluminum strip

For aluminum strip cutting, quality inspection personnel should pay close attention to whether there are scratches in the winding process of the equipment, because if there are foreign bodies in the equipment during the longitudinal cutting process, the aluminum coil will have scratches of texture size and trend of straight line from beginning to end, which has a greater impact on the surface quality, so pay attention to scratches during the winding process, and the scratch has been found to stop production immediately. And find out why.

Usually, aluminum strip scratches almost all appear in the slitting process, and there are fewer problems with the masterbatch, so the slitting processing staff should check and clean the foreign matter on the production line before processing, pay attention to the abnormal surface of the aluminum strip during production, observe whether there is a scratch on the surface of the aluminum strip during packaging, and stop production in time if the masterbatch has a scratch and reflect it in time. The surface of the finished product is smooth and without marks, the plate shape is flat, and the section is neat after chamfering process to achieve rounded corners and zero burrs. After processing, the aluminum strip can not produce any new surface defects (such as scratches, transverse shock marks left by the straightener, etc.) Note: Timely replacement and cleaning of anti-scratches treatment on the surface of each unit.

Transformer aluminum strip is mainly used to do dry transformer internal winding, appearance quality to achieve neat section, rounded corners, no burrs, loose coil, bar, tower type and other defects. No roll marks, black lines, bright spots, scratches, bumps and other defects on the surface. The surface has no oil spots, tears, bubbles and other phenomena formed after annealing. Description: Smooth surface, no scratches. The side can be chamfered, smooth, better than the national standard. Resistivity less than or equal to 0.028. Packaging: wooden tray, with moisture-proof paper, intermediate paper sleeve, inner diameter 300mm or 500mm. Free sample, large quantity, price superior Aluminum content: ≥99.6% Implementation standard: GB/T3190-1996 Elongation: ≥35% Tensile strength: 60-95Mpa Delivery time: 7-15 days Use: Mainly used in large transformers, solar energy, electric power and other industries. The company has a large number of transformer aluminum belt stock all year round, if you need transformer aluminum belt can contact us, we will provide you with quality products, intimate service to provide you with perfect service.

The main reasons for the surface damage of the aluminum strip are as follows: there are a certain number of hard metal particles in the ingot, and the surface of the ingot is attached to debris or ingot composition segregation. When there is a large amount of segregation emerging on the ingot surface and the ingot is not homogenized or the homogenization treatment effect is not good. During the extrusion process, when metal flows through the work belt, these segregation surfaces or hard metal particles adhere to the work belt surface or cause damage to the work belt, and finally cause scratches to the aluminum belt surface. (2) There are debris on the work belt, so that the surface of the work belt is injured during extrusion and scratch the aluminum belt; When it comes into contact with the aluminum strip, it will cause scratches on the surface of the aluminum strip. ③ There are hard inclusions in bare metal or graphite strips on the discharge track or swing bed. Due to the high speed caused by aluminum belt damage; ④ When the fork rod carries the aluminum strip from the discharge track to the swing bed. ⑤ Scratches caused by artificially dragging aluminum belts on the swing bed; ⑥ Friction or extrusion between aluminum strips during transportation causes damage.

Solution: Strengthen the control of ingot quality; Minimize the contact damage between the aluminum belt and the auxiliary equipment. ③ The aluminum strip is isolated from the auxiliary equipment with soft felt. Try to prevent dragging or turning the aluminum belt at will, and clean up foreign bodies on the felt in time. ④ Handle lightly in production. Try not to rub against each other. ⑤ Reasonable placement of aluminum tape in the material frame.
