The manufacturer of AL Foil for transformer tells you that the difficult control of thickness deviation is a characteristic of aluminum box rolling. The thickness difference of 3% is not difficult to control in the production of plates and strips, but it is difficult to control in the production of aluminum foil.

The manufacturer of AL Foil for transformer tells you that as the thickness of the aluminum box decreases, its micro-conditions can affect it, such as temperature, oil film, oil and gas concentration, etc. Aluminum foil rolling can reach hundreds of thousands of meters per roll, and the rolling time is about 10 hours. Errors in thickness measurement are easy to form as time goes by. The only means of adjusting the thickness of aluminum foil is tension and speed. The manufacturer of AL Foil for transformer tells you that these factors have caused difficulties in thickness control of aluminum foil rolling.
Therefore, to really control the thickness difference of the aluminum box within 3%, many conditions are required to ensure: AL Foil for transformer manufacturers tell you to use aluminum foil blanks with 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 discovered when the side thickness system fails.
