Jumbo Aluminium Foil 14 Micron rolling process, the foil thickness with the rolling system of the rise of the phenomenon known as the speed effect. For the explanation of the mechanism of the speed effect is still pending in-depth study, the reasons for the speed effect is generally believed to have the following three aspects:
Work rolls and rolling material friction between the state of change, with the rolling Jumbo Aluminum Foil 14 Micron speed increases, the lubricating oil to increase the amount of lubricant brought in, so that the lubrication state between the rolls and rolling material changes. The friction coefficient decreases, the oil film becomes thicker, and the thickness of the aluminium foil is then thinned.

Changes in the rolling mill itself. In mills with cylindrical bearings, as the rolling Jumbo Aluminum Foil 14 Micron speed increases, the roll necks will float in the bearings, thus causing the two interacting loaded rolls to move in the direction of leaning against each other.
The material is softened by the process when it is rolled and deformed. High-speed Jumbo Aluminium Foil 14 Micron mill rolling speed is very high, with the increase in rolling speed, rolling the temperature of the deformation zone to open high, according to calculations of the deformation zone of the metal temperature can rise to 200 ° C, equivalent to an intermediate recovery annealing, thus causing the processing of the rolled material softening phenomenon.
GNEE solution to the difficulties in controlling the thickness difference
Strict control of the Jumbo Aluminum Foil 14 Micron production environment and process parameters, such as temperature, oil film and oil/gas concentration, to minimise 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.
GNEE's measures to ensure the thickness difference of Jumbo Aluminium Foil 14 Micron is within 3%
Comprehensive control from various aspects, such as production environment, process parameters, equipment accuracy, personnel operation, etc., in order to minimise the thickness difference.
Regularly carry out equipment maintenance and calibration to ensure the normal operation and precision of the equipment.
Establish a sound quality management system to monitor and manage the aluminium foil production process comprehensively to ensure that the aluminium foil products produced meet the quality requirements.
Continuously research and develop new aluminium foil rolling technologies and methods to improve the quality and production efficiency of aluminium foil.
