Leben alumina sare leh
Leben alumina sare leh
Faa’iidooyinka badeecada: dib -u -kicinta sare iyo heerkulka jilicsanaanta culayska, oo leh kororka waxyaabaha Al2O3, waxqabadka iska -caabbinta slag ayaa si weyn loo hagaajiyay.
Codsiga badeecada: Inta badan waxaa loo adeegsadaa dahaarka foornooyinka qarxa, foornooyinka qarxa kulul, korka foornada korontada, foornooyinka qarxa, foornooyinka dib -u -noqoshada, iyo foornooyinka wareega. Intaa waxaa dheer, lebenkii alumina ee sare ayaa sidoo kale si ballaaran loo adeegsadaa sida lebenkii hubiyaha dib -u -cusboonaysiinta dabka, bareesooyinka loogu shubo nidaamyada, lebenkii biiyaha, iwm.
sharaxaadda alaabta
Ku -rakibidda lebenkii alumina ee sarreenka ku jiray waa tiknoolajiyad aad u muhiim ah, gaar ahaan meelaha leh qaab -dhismeedyo qalafsan, is -beddel weyn oo qalooca iyo qaybo qaanso leh oo saqafka foornada ah. Rakibaadda liita ee lebenada alumina ee sare waxay u horseedi kartaa kulayl aad u sarreeya ama dab socda. Lebenkii jaban ee caadiga ahaa ayaa dhibaato weyn u keeni doona dhismaha. Sidaa darteed, waxaa lama huraan ah in la habeeyo lebiska aluminium-sare ee qaaska ah, kaas oo yarayn kara dhibka dhismaha iyo baabi’inta meelaha bannaan ee laga yaabo inay ka dhashaan dhibaatooyinka dhismaha marka la isticmaalayo lebenkii caadiga ahaa ee alumina sare. Nolosha dabka.
Tayada qaab-dhismeedka lebenkii sare ee alumina ee qaabka gaarka ah leh waa inay buuxiyaan shuruudaha soo socda:
(1) Dulqaadka cabbirka: dulqaadka dhererka ± 2%; dusha sare ee u-samayska weyn iyo dulqaad ballaadh ballaadhan ee madaxa ± 2mm; dulqaadka farqiga cabbirka ± 1mm; dulqaadka dhererka ± 1%. Lebenkii alumina sare ee sida gaarka ah loo sameeyay, farqigu waa 2mm.
(2) Luminta geeska. U oggolow dhinaca kulul ama qabow inay laba dhinac waxyeeleeyaan ilaa 40mm dherer iyo 5mm qoto dheer; laakiin looma oggola inuu dhaafo.
(3) Khasaare joogto ah. Waxaa jira hal dhaawac oo geeska ah oo lebenkii alumina-ka ahaa ee caadada u ahaa dusha sare iyo kulaylka, iyo dhererka guud ee saddexda daraf ee dhaawaca geeska waa inuusan dhaafin 50mm. Luminta xagasha oo aan ka badnayn 20mm lama tixgeliyo.
(4) Dildilaacyo. Dusha lebenku waxaa loo oggol yahay inuu yeesho dildilaacyo u eg timo; lama dillaacayo barbar -dhigga dushiisa oo la oggol yahay; dildilaacyo kale oo aan ka badnayn 40mm oo aan ka ballaarnayn 0.2mm ayaa la oggol yahay.
(5) Godad, calaamado dhalaalaya iyo burooyin. Godadka la oggol yahay iyo calaamadaha dhalaalaya waa 10mm dhexroor iyo 10mm qoto dheer; dhumucdiisuna waa 0.5mm. Lebenkii alumina ee sare oo leh cidhifyo kala duwan oo kala duwan oo ka kooban tiro leben ah kama badnaan doonaan 70% wadarta.
