Rolling yog txheej txheem uas lub ingot yog rub mus rau hauv lub rotating yob los ntawm kev sib txhuam. Lub ingot yog txo nyob rau hauv cross section los ntawm lub siab thov los ntawm cov yob, cov duab yog hloov, lub thickness yog thinned, thiab qhov ntev yog nce. Rolling txheej txheem yas deformation.
Raws li cov lus qhia sib txawv ntawm cov yob, cov dov tuaj yeem muab faib ntxiv rau hauv ntsug dov, hla dov thiab hla dov. Nyob rau hauv lub longitudinal dov, cov rolls ua hauj lwm tig nyob rau hauv opposite lus qhia, thiab longitudinal axis ntawm dov Tshuag yog perpendicular mus rau lub axis ntawm cov yob. Longitudinal dov yog txoj kev siv ntau tshaj plaws rau kev sib tw tiaj tus dov ntawm aluminium alloy nplooj ntawv, strips thiab foils; Hauv kev sib tw dov, cov rolls ua hauj lwm tig mus rau tib qho kev taw qhia, thiab cov axis longitudinal ntawm cov khoom dov yog sib npaug rau cov yob axis. Hla dov yog tsis tshua muaj siv nyob rau hauv aluminium alloy ntawv sawb dov; Nyob rau hauv cov ntaub ntawv ntawm tus ntoo khaub lig dov, cov rolls ua hauj lwm tig nyob rau hauv tib txoj kev, thiab lub longitudinal axis ntawm dov Tshuag yog inclined ntawm ib tug tej lub kaum sab xis nrog lub yob axis. Hla- dov feem ntau yog siv rau kev tsim cov kav dej aluminium alloy thiab qee cov khoom zoo li tus.
Nyob ntawm cov txheej txheem yob, aluminium alloy dov tuaj yeem muab faib ua ob - yob dov, ntau- yob dov thiab tshwj xeeb dov (xws li planetary dov, V- dov, thiab lwm yam) dov. Nyob ntawm cov duab ntawm cov yob, aluminium alloy dov tuaj yeem muab faib ua cov yob yob thiab lub qhov yob yob. Raws li cov khoom sib txawv, aluminium alloy dov tuaj yeem muab faib ua phaj, siv thiab ntawv ci dov, bar, tiaj bar thiab profiled profile dov, yeeb nkab thiab hollow profile dov.
