How to solve the problem of black strip on the surface of transformer aluminum tape foil
After rolling the strip surface with soft material gently wipe, will more or less wipe off some white powder, we call it aluminum powder. Is aluminum in the deformation zone of rolling surface by roller friction and wear, the main composition of Al₂O₃, Al powder and a small amount of filter aid agent residue, heat treatment can not eliminate. It destroys the beauty of the product surface, and affects the performance of the product. Especially for cold rolled strip products, because our equipment adopts longitudinal shear mode between looper, looper and coiling machine using the mop plate to establish coiling tension, shear during the mop plate there are many sticky powder from the surface of the strip to wipe, aluminum powder and strip surface blow clean in a black oil mixture, the surface of the strip.
Henan Signi Aluminum Co., Ltd. explores the causes of aluminum powder, and puts forward measures to eliminate aluminum defects, which is of great significance to improve the surface quality of transformer aluminum tape foil, improve the yield, and ensure the sustainable development of enterprises.
Influencing factors and preventive measures of aluminum powder defects:
1. Effect of roller roughness.
2. The influence of roller diameter
3. Effect of roller hardness
4. Effect of deformation zone temperature
5. Effect of down pressure rate
6. Effect of rolling speed
7. Effect of process lubricating oil
8. Effect of oil content on surface strip
Our use of the mop plate longitudinal shearing strip surface cleaning and coiling tension, in the cutting process the wool quality of the mop plate there are many sticky powder from the surface of the strip to wipe, and aluminum strip surface oil mixed on the surface of transformer aluminum tape foil, affect the surface quality. A simple cleaning device is added to the slitting machine. The principle is to clean the strip rolling oil and aluminum powder with high pressure cleaning oil and brush roller; to clean the oil inlet side with the squeeze roller; to suck the residual oil on the strip surface with the vacuum roller. The cleaning device installed in the longitudinal shear has a good effect of removing oil and powder, and effectively solved the black strip problem on the transformer aluminum tape foil。
