Aluminium ntawv ci yog ib yam khoom ntawm txhuas dov. Aluminium ntawv ci feem ntau yog hais txog thickness. Hauv kev lag luam, cov khoom siv txhuas uas muaj qhov tuab tsawg dua 0.2 hli feem ntau hu ua aluminium foil. Cov npoo feem ntau yog txiav vertically thiab xa hauv yob.
Aluminium ntawv ci tuaj yeem muab faib ua ob chav xoom ntawv, ib qho xoom ntawv ci thiab tuab ntawv txhuas sawb raws li tuab. Cov ntawv ci tuab yog {{0}}.1 ~ 0.2mm; single-zero foil hais txog txhuas ntawv ci nrog lub thickness ntawm 0.{{10}}1mm thiab tsawg dua 0.1mm/; double-zero foil yog hais txog ib daim ntawv nrog ob xoom tom qab tus lej taw tes thaum lub thickness ntsuas hauv mm, feem ntau lub thickness yog tsawg dua 0.01 txhuas ntawv ci, uas yog, 0.005 ~ 0.009mm txhuas ntawv ci. Cov khoom siv sib txawv kawg yuav muaj cov thickness sib txawv. Feem ntau hais lus, ob daim ntawv xoom yog siv rau kev ntim khoom noj, ntim luam yeeb, hluav taws xob kho qhov muag, thiab lwm yam; ib qho xoom ntawv ci yog siv rau qee qhov ntim khoom noj, ntim tshuaj, hluav taws xob hluav taws xob tiv thaiv hluav taws xob, ntawv ci cua txias, thiab lwm yam; tuab ntawv ci yog tsuas yog siv rau cua txias ntawv ci, Thawv ntawv ci, architectural kho kom zoo nkauj thiab muaj kev siv.
Cov txheej txheem aluminium ntawv ci yog cov khoom siv txhuas nrog cov txheej txheem ua tiav, qhov tsawg tshaj plaws thickness, thiab qhov nyuaj tshaj plaws hauv kev lag luam aluminium. Tam sim no, muaj ob txoj kev siv thev naus laus zis hauv kev lag luam: (1) Ingot kub dov txoj kev; (2) Ob chav-roller casting thiab dov txoj kev. Txoj kev ntxaib-yob casting thiab dov txoj kev yog dhau los ua txoj hauv kev tseem ceeb.
(1) Ingot kub dov txoj kev: Ua ntej, cov txhuas yaj yog cam khwb cia rau hauv lub tiaj tus ingot. Tom qab homogenization, kub dov, txias dov, intermediate annealing thiab lwm yam txheej txheem, nws yog txuas mus rau txias dov rau hauv lub phaj nrog ib tug tuab ntawm txog 0.4 ~ 1.0 hli raws li ib tug ntawv ci. Cov khoom tsis muaj (casting → kub dov thiab blanking → txias dov → ntawv ci dov).
(2) Muab ob npaug rau-roller casting thiab dov txoj kev: Piv nrog rau ingot kub dov txoj kev, cov txheej txheem ntws ntawm kev tsim txhuas ntawv ci blanks los ntawm casting thiab dov txoj kev yog kuj yooj yim; Nws tsis tas yuav mus dhau cov txheej txheem nyuaj xws li melting ingots, milling, homogenization thiab kub dov. Tsis tas li ntawd, cov txhuas yaj yog nchuav ncaj qha rau hauv ob lub rotating casting rollers (crystallizers), thiab ob txheej txheem ntawm solidification thiab kub dov yog ua tiav ib txhij nyob rau hauv lub casting thiab dov cheeb tsam li ntawm 2 mus rau 3 vib nas this, thiab ib tug phaj nrog ib tug tuab ntawm 4. mus 7 mm. Zoo ib yam li kub-dov txhuas ntawv ci billets, cam khwb cia dov daim hlau kuj yuav tsum tau mus los ntawm ib tug series ntawm txias dov thiab intermediate annealing txheej txheem, thiab thaum kawg dov rau hauv 0.3 ~ 0.7 hli tuab daim hlau raws li aluminium foil billets.
