Nyob rau hauv kev tsim ntawm ob daim ntawv ci, dov ntawm aluminium ntawv ci yog muab faib ua peb txheej txheem: ntxhib dov, nruab nrab dov, thiab ua tiav dov. Los ntawm qhov kev xav ntawm kev siv tshuab, nws tuaj yeem sib cais los ntawm qhov tuab ntawm qhov yob tawm. Los yog sib npaug rau 0.05mm yog rolling ntxhib, qhov tawm thickness yog nruab nrab ntawm 0.013 ~ 0.05mm yog nruab nrab dov, thiab ib qho khoom tiav thiab ob npaug dov tiav cov khoom nrog tawm thickness tsawg dua 0.013mm yog tiav dov. Rough rolling zoo ib yam li cov yam ntxwv dov ntawm aluminium ntawv thiab sawb. Kev tswj ntawm thickness mas nyob ntawm dov quab yuam thiab tom qab nro. Cov txheej txheem ntawm ntxhib dov yog tsawg heev. Nws qhov tshwj xeeb feem ntau muaj cov hauv qab no:
1. Aluminium sawb dov. Ua kom cov txhuas sawb thinner feem ntau yog nyob ntawm lub zog dov, yog li txoj kev tswj tsis siv neeg ntawm cov phaj tuab yog ua raws li qhov sib txawv ntawm qhov sib txawv raws li hom kev tswj tseem ceeb ntawm AGC, txawm tias lub zog dov hloov, lub thickness tuaj yeem tau txais los ntawm kev siv lub zog ntawm cov hlau nplaum. kho qhov sib txawv ntawm qhov yob txhua lub sijhawm kom cov yob qhov sib txawv ntawm ib qho nqi sib npaug ntawm daim ntawv thiab sawb. Los ntawm aluminium ntawv ci dov mus rau nruab nrab tiav dov, vim hais tias lub thickness ntawm aluminium ntawv ci yog heev nyias, nws yog yooj yim los mus nce lub dov quab yuam thaum dov kom lub yob elastically deformed dua li cov khoom dov los tsim cov yas deformation. Lub elastic flattening ntawm yob yog tsis yooj yim sua. Tsis pom zoo, lub caij nplooj ntoos hlav dov thiab flattening ntawm yob txiav txim siab tias nyob rau hauv cov ntawv txhuas dov, lub dov quab yuam tsis tuaj yeem ua lub luag haujlwm tib yam li dov lub phaj. Aluminium foil dov feem ntau yog dov yam tsis muaj qhov sib txawv ntawm qhov sib txawv nyob rau hauv lub siab tas li, thiab cov tuab ntawm cov ntawv txhuas yog kho. Nws tsuas yog nyob ntawm qhov hloov kho nro thiab dov ceev.
2. stacking dov. Rau ultra-nyias aluminium ntawv ci nrog lub thickness tsawg dua 0.012mm (thickness yog hais txog txoj kab uas hla ntawm lub yob ua hauj lwm), vim yog elastic flattening ntawm yob, nws yog ib qho nyuaj heev rau siv ib daim ntawv dov txoj kev, yog li ob txoj kev dov yog saws. Txoj kev ntxiv roj lubricating ntawm ob nplooj ntawv ntawm txhuas ntawv ci thiab dov lawv ua ke (tseem hu ua pawg dov). Stack dov tuaj yeem tsis tsuas yog yob tawm cov ntawv txhuas nyias nyias uas tsis tuaj yeem tsim los ntawm ib daim ntawv dov, tab sis kuj txo tus naj npawb ntawm cov strips tawg thiab txhim kho kev ua haujlwm. Siv cov txheej txheem no, ib leeg-sab du aluminium ntawv nyiaj ntawm 0.006mm txog 0.03mm tuaj yeem ua rau hauv cov khoom siv.
3. Ceev nyhuv. Thaum lub sij hawm cov txheej txheem aluminium ntawv yob, qhov tshwm sim uas cov thickness ntawm cov ntawv ci yuav thinner nrog qhov nce ntawm dov degree yog hu ua cov nyhuv ceev. Kev piav qhia ntawm cov nyhuv nrawm nrawm tseem yuav tsum tau kawm hauv qhov tob. Cov laj thawj rau cov nyhuv nrawm feem ntau ntseeg tias muaj peb yam hauv qab no:
a. Kev sib txhuam lub xeev ntawm kev ua haujlwm yob thiab cov khoom siv dov hloov. Nrog rau qhov nce ntawm qhov dov ceev, tus nqi ntawm cov roj lubricating tau nce, kom lub lubrication xeev ntawm cov yob thiab cov khoom dov hloov. Lub coefficient ntawm kev sib txhuam txo, cov roj zaj duab xis yuav thicker, thiab lub thickness ntawm aluminium ntawv ci txo raws li.
b. Kev hloov pauv hauv lub tshuab dov nws tus kheej. Nyob rau hauv ib lub rolling zeb nrog cylindrical bearings, raws li lub dov ceev nce, lub caj dab yob yuav ntab nyob rau hauv cov kabmob, yog li ntawd ob tug interactively loaded yob yuav txav mus rau ib leeg.
c. Ua softening thaum cov khoom yog deformed los ntawm dov. Lub dov ceev ntawm high-speed aluminium foil dov zeb yog siab heev. Nrog rau qhov nce ntawm dov ceev, 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 C, uas yog sib npaug rau qhov nruab nrab rov qab annealing, yog li ua rau kev ua haujlwm softening ntawm cov ntaub ntawv dov.
