Aluminum Alloy Foil For Tranformer Winding manufacturers tell you that the thickness deviation is difficult to control is a characteristic of aluminum box rolling. The thickness difference of 3% is not difficult to control in the production of sheet and strip, but it is more difficult to control in the production of aluminum foil.

Aluminum Alloy Foil For Tranformer Winding manufacturers tell you that as the thickness of the aluminum foil decreases, its trace conditions can affect it, such as temperature, oil film, oil and gas concentration, etc. A roll of aluminum foil can be rolled up to hundreds of thousands of meters, and the rolling time is about 10 hours. The error of thickness measurement is easy to form with time.
The only means of adjusting the thickness of the aluminum foil are tension and speed. Aluminum Alloy Foil For Tranformer Winding manufacturers tell you that these factors have caused the difficulty in thickness control of aluminum foil rolling.
Therefore, to really control the thickness difference of the aluminum foil within 3%, many conditions need to be used to ensure: Aluminum Alloy Foil For Tranformer Winding manufacturers tell you to use aluminum foil blanks of qualified thickness; adjust and control the reduction and roll shape during rolling , and the rolls are ground according to the specified parameters; the rolling process is stabilized; the thickness of the aluminum box is frequently measured during the rolling process, so as not to be found when the side thickness system fails, etc.
