Ew taybetmendiyek rijandina qutiya aluminiumê ye ku kontrolkirina veguheztina qalindiyê dijwar e. Cûdahiya stûrbûna 3% kontrolkirina di hilberîna plak û hêlînê de ne dijwar e, lê di hilberîna pelê aluminium de kontrolkirina wê dijwartir e.
Her ku qalindahiya qutiya aluminiumê ziravtir dibe, şert û mercên wê yên mîkro dikare bandorê li wê bike, wek germahî, film rûnê, and oil and gas concentration. A roll of aluminum foil can be rolled up to hundreds of thousands of meters, and the rolling time is as long as about 10 demjimêr, and the error of thickness measurement is easy to form with time.
The only way to adjust the thickness of aluminum foil is tension and speed.
These factors have caused difficulties in thickness control of aluminum foil rolling.
Ji ber vê yekê, to truly control the thickness difference of the aluminum box within 3%, many conditions are needed to ensure: use the aluminum foil blank of the qualified thickness; adjust and control the reduction and roll shape during rolling, and the roll is ground according to the specified parameters ; Stabilize the rolling process; frequently measure the thickness of the aluminum box during the rolling process, so as not to be undetected when the side thickness system fails.
