Nws yog tus yam ntxwv ntawm txhuas lub thawv dov uas lub thickness sib txawv yog qhov nyuaj rau kev tswj. Lub thickness sib txawv ntawm 3% tsis yooj yim rau kev tswj hauv kev tsim cov phaj thiab sawb, tab sis nws yog qhov nyuaj dua los tswj hauv kev tsim cov ntawv txhuas.
Raws li lub thickness ntawm aluminium lub thawv yuav thinner, nws cov kab mob micro tuaj yeem cuam tshuam rau nws, xws li kub, oil zaj duab xis, 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 xuabita, 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.
Yog li ntawd, 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.
