Aluminium ntawv ci yob

Qhov tshwj xeeb ntawm aluminium foil dov
Hauv kev tsim cov ntawv ci ob npaug, lub dov ntawm aluminium ntawv ci muab faib ua peb txheej txheem: ntxhib dov, nruab nrab dov thiab ua tiav dov. Los ntawm txoj kev xav ntawm kev siv tshuab, nws tuaj yeem faib ua roughly faib raws li lub thickness ntawm lub qhov hluav taws xob dov. Txoj kev faib tawm dav dav yog tias lub qhov hluav taws xob tuab yog ntau dua lossis sib npaug rau {{0}}}05mm rau kev ntxhib dov, qhov hluav taws xob tuab yog nruab nrab ntawm 0.013 thiab 0.05 rau nruab nrab dov, thiab qhov hluav taws xob tuab yog tsawg dua 0.013mm rau ib qho khoom tiav thiab ob chav dov tiav cov khoom rau kev ua tiav dov. Qhov ntxhib dov zoo ib yam li cov yam ntxwv dov ntawm aluminium strips. Lub thickness tswj tsuas yog nyob ntawm lub dov quab yuam thiab tom qab nro. Qhov ntxhib dov ua tus nqi thickness yog tsawg heev. Nws cov yam ntxwv dov yog txawv kiag li los ntawm dov ntawm txhuas strips. Nws muaj qhov tshwj xeeb ntawm aluminium foil dov. Nws cov yam ntxwv yog feem ntau nyob rau hauv cov nram qab no yam:
(1) Aluminium sawb dov. Ua kom cov txhuas sawb thinner, nws tsuas yog nyob ntawm lub zog dov. Yog li ntawd, lub phaj thickness tsis siv neeg tswj txoj kev yog ib txoj kev tswj nrog tas li yob sib txawv raws li lub ntsiab lub cev ntawm AGC. Txawm hais tias lub zog dov hloov, qhov sib txawv ntawm qhov yob tuaj yeem hloov kho txhua lub sijhawm kom cov yob sib txawv ntawm ib qho nqi kom tau txais lub phaj nrog tuab tuab. Thaum cov ntawv ci txhuas yog dov mus rau qhov nruab nrab ua tiav dov, vim qhov nyias nyias ntawm cov ntawv ci aluminium, nws yooj yim dua los ua kom lub zog dov thaum dov kom cov menyuam ua elastic deformation dua li cov khoom siv dov ua cov yas deformation. Lub elastic flattening ntawm cov menyuam tsis tuaj yeem tsis quav ntsej. Lub elastic flattening ntawm cov menyuam txiav txim siab tias nyob rau hauv dov ntawm txhuas ntawv ci, lub dov quab yuam tsis plays tib lub luag hauj lwm raws li lub dov ntawm phaj. Aluminium foil dov feem ntau yog ib qho yob gapless dov nyob rau hauv lub siab tsis tu ncua. Kev hloov kho ntawm cov tuab ntawm aluminium ntawv ci feem ntau yog nyob ntawm kev hloov kho ntawm qhov nro thiab dov ceev.
(2) Overlap dov. Rau cov ntawv ci txhuas nyias nyias nrog lub thickness tsawg dua 0.012mm (qhov tuab yog cuam tshuam nrog txoj kab uas hla ntawm cov yob ua haujlwm), vim yog elastic flattening ntawm cov menyuam, nws nyuaj heev. siv ib daim ntawv dov txoj kev. Yog li ntawd, ob txoj kev dov yog saws, uas yog, ntxiv lubricating roj ntawm ob nplooj ntawv ntawm txhuas ntawv ci thiab ces dov lawv ua ke (tseem hu ua overlap rolling). Cov txheej txheem sib tshooj dov tuaj yeem tsis tsuas yog tsim cov ntawv txhuas nyias nyias uas tsis tuaj yeem tsim los ntawm ib daim ntawv dov, tab sis kuj txo cov strips so thiab txhim kho kev ua haujlwm. Cov txheej txheem no tuaj yeem tsim cov khoom tsim ib leeg ib sab du aluminium ntawv ntawm 0.006mm txog 0.03mm.
(3) Kev nrawm nrawm. Thaum lub sij hawm dov txheej txheem ntawm txhuas ntawv ci, qhov tshwm sim uas lub thickness ntawm cov ntawv ci yuav thinner li dov ceev 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 yog peb yam hauv qab no:
1) Kev sib txhuam lub xeev ntawm kev ua haujlwm yob thiab cov khoom siv dov hloov pauv. Raws li lub dov ceev nce, tus nqi ntawm cov roj lubricating tau nce, yog li hloov lub xeev lubrication ntawm yob thiab cov khoom siv dov. Kev sib txhuam coefficient txo qis, cov roj zaj duab xis yuav thicker, thiab lub thickness ntawm aluminium ntawv ci txo raws li.
2) Kev hloov pauv hauv lub tshuab dov nws tus kheej. Rau lub tshuab dov siv cylindrical bearings, raws li qhov dov ceev nce, lub caj dab yob yuav ntab rau hauv cov kabmob, kom ob qho kev sib cuam tshuam yob yuav txav mus 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. Nrog rau qhov nce ntawm dov ceev, qhov kub ntawm qhov dov deformation cheeb tsam nce. Nws yog xam tias 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 cov txheej txheem softening tshwm sim ntawm cov khoom dov.
Lub hauv paus ntsiab lus rau kev tsim cov txheej txheem aluminium foil dov
① Kev txiav txim siab ntawm tag nrho cov txheej txheem tag nrho Tus nqi ua tiav yog hais txog tag nrho cov deformation degree ntawm cov ntawv ci los ntawm recrystallization annealing rau dov tawm cov khoom tiav. Feem ntau hais lus, tag nrho cov txheej txheem ua tiav ntawm 1 series tuaj yeem ncav cuag ntau dua 99%, thiab qee qhov 8 series khoom kuj tuaj yeem ncav cuag tus nqi no, tab sis tag nrho cov txheej txheem ntawm aluminium alloy ntawv ci feem ntau qis dua 90%.
② Kev txiav txim siab ntawm kev ua tiav qhov kev txiav txim siab ntawm kev ua tiav yog qhov tseem ceeb ntawm cov txheej txheem dov. Rau cov khoom lag luam ntshiab aluminium series, qhov kev ua tiav tuaj yeem ncav cuag 65%. Rau thawj kis tom qab lub billet yog annealed, nws tsis yog pom zoo kom siv loj heev tus nqi ua, feem ntau txog 50%.
Rolling thickness
Lub ntsiab thickness ntsuas txoj kev rau txhuas ntawv yob yob yog eddy tam sim no thickness ntsuas, isotope ray thickness ntsuas thiab X-ray thickness ntsuas. X-ray thickness ntsuas yog feem ntau siv thickness ntsuas txoj kev nyob rau hauv txhuas ntawv ci ntau lawm, tshwj xeeb tshaj yog nyob rau hauv high-ceev aluminium foil dov mills. Thickness tswj txoj kev thaum lub sij hawm txhuas ntawv yob yob muaj xws li: dov quab yuam tswj, nruj tswj, dov ceev tswj, nro / ceev, ceev / nro tswj. [1]
