Control the thickness difference of aluminum foil

The difficulty in controlling the thickness deviation is a feature of aluminum box rolling. The thickness difference of 3% is not difficult to control in the production of sheet and strip, but it is difficult to control in the production of aluminum foil.

As the thickness of the aluminum box is reduced, its trace conditions can affect, such as temperature, oil film, oil and gas concentration. A roll of aluminum foil can reach several hundred thousand meters, and the rolling time can be as long as about 10 hours. The error of thickness measurement is easy to form with time.

The only way to adjust the thickness of the aluminum foil is tension and speed.These factors all contribute to the difficulty of thick control of aluminum foil rolling.Therefore, the thickness of the actual control aluminum box is less than 3%, and many conditions are required to ensure: use of aluminum foil blanks of acceptable thickness; adjustment, control of reduction and roll type during rolling, and grinding of the rolls according to specified parameters. Stable rolling process; the thickness of the aluminum box is measured during the rolling process so as not to be found when the side thickness system fails.
