Thaum lub sij hawm dov txheej txheem ntawm aluminium ntawv ci, qhov tshwm sim uas lub thickness ntawm cov ntawv ci yuav thinner nrog rau qhov nce ntawm dov degree yog hu ua cov nyhuv ceev. Qhov kev piav qhia ntawm cov nyhuv nrawm nrawm tseem xav tau kev tshawb fawb tob. Cov laj thawj rau cov nyhuv nrawm feem ntau ntseeg tias muaj peb yam hauv qab no:
1) Kev sib txhuam lub xeev ntawm kev ua haujlwm yob thiab cov khoom siv dov hloov. Raws li lub dov ceev nce, tus nqi ntawm cov roj lubricating tau nce, yog li ua rau lub xeev lubrication ntawm cov yob thiab cov khoom dov hloov. Kev sib txhuam coefficient txo qis, cov roj zaj duab xis yuav thicker, thiab lub thickness ntawm aluminium ntawv ci yuav thinner.
2) Kev hloov pauv hauv lub tshuab dov nws tus kheej. Nyob rau hauv ib lub rolling zeb siv cylindrical bearings, raws li lub dov ceev nce, lub caj dab yob yuav ntab nyob rau hauv cov kabmob, kom ob tug interacting loaded yob yuav txav los ze zog rau ib leeg.
3) Ua softening thaum cov khoom yog deformed los ntawm dov. Lub dov ceev ntawm high-speed aluminium foil dov zeb yog siab heev. Raws li qhov dov ceev nce, qhov kub ntawm qhov dov deformation cheeb tsam nce. Raws li kev suav, cov hlau kub hauv cheeb tsam deformation tuaj yeem nce mus rau 200 degree, uas yog sib npaug rau qhov nruab nrab rov qab annealing, yog li ua rau txheej txheem softening tshwm sim ntawm cov ntaub ntawv dov.
