Difficulty in controlling the thickness difference is one of the characteristics of aluminium foil rolling.
Why is it so difficult to control the thickness difference in aluminium foil production
What are the elements of thickness control in aluminium foil rolling?
How to ensure that the thickness difference can be controlled within 3% in real terms.
Solution segmentation:
Reasons for the difficulty in controlling the thickness difference
The thickness of aluminium foil is very thin, so small changes, such as temperature, oil film, oil and gas concentration, can have a significant effect on its thickness.
The long rolling process of aluminium foils, which can last up to 10 hours or more, increases the likelihood of thickness differences forming.
There are limited means of adjusting thickness, mainly through tension speed.
Solutions to difficulties in controlling thickness differences
Strict control of the production environment and process parameters, such as temperature, oil film and oil/gas concentration, to reduce the impact of external conditions on foil thickness.
Use advanced monitoring equipment to monitor the thickness of aluminium foil in real time, so as to detect and adjust the thickness difference in time.
Optimise and upgrade rolling equipment to improve the precision and stability of the equipment to better control the thickness of aluminium foil.
Strengthen the training of operators to improve their understanding and mastery of the aluminium foil rolling process so that they can control the thickness of aluminium foil more accurately.
