Txheej txheem ntawm tooj liab thiab tooj liab alloy daim ntawv, sawb thiab ntawv ci

Txheej txheem ntawm tooj liab thiabtooj liab alloyntawv, strip thiab foil:
Rolling yog txoj kev yooj yim rau kev tsim cov tooj liab thiab tooj liab alloy strips.Rolling yog nyob rau hauv qhov sib txawv ntawm ob lub yob uas muaj qee qhov siab ntawm ib leeg thiab tig mus rau cov lus qhia tawm los yob tawm cov khoom, thiab cov tuab ntawm cov khoom siv raw yuav thinner.Cov txheej txheem dov deformation.Raws li cov kev sib txawv ntawm kev muab cov khoom siv, cov khoom siv tooj liab hlau nplaum tuaj yeem muab faib ua plaub hom: ingot dov txoj kev, ingot forging dov txoj kev, nruam casting billet dov txoj kev, thiab extrusion billet dov txoj kev.
1. Txoj kev ingot dov, feem ntau yog kub dov, yog thawj cam khwb cia tooj liab thiab tooj liab alloys rau hauv loj ingots, thiab ua kom sov rau ib tug tej yam kub, uas yog, siab tshaj qhov recrystallization kub ntawm cov khoom alloy, uas feem ntau yog heev ntawm 0.8. ~ 0.9 ntawm lub melting point ntawm cov hlau, nws yog kub dov rau hauv ib lub slab los yog sawb.Qhov no yog txoj kev ua ib txwm ua rau tooj liab ua daim hlau thiab strips, thiab nws kuj yog ib txoj kev uas tseem niaj hnub siv.Nws muaj peev xwm loj thiab ua haujlwm siab, thiab tsim nyog rau ntau yam thiab loj-teev ntau lawm.
2. Cov txheej txheem extrusion dov feem ntau yog hais txog cov txheej txheem txuas ntxiv extruding lub billet rau hauv ib lub strip los ntawm kev siv tus pas nrig nruam nruam.Txoj kev no tau qhia pom tseeb qhov zoo hauv kev tsim cov tooj liab tuav.Tam sim no, qee cov tuam txhab tooj liab alloy tau ua tiav cov khoom ntawm 300mm wide-band billets.Yog vim li cas rau qhov kev txaus siab nyob rau hauv txoj kev no yog feem ntau vim hais tias cov peev ntawm txoj kev no yog ntau npaum li cas qis dua qhov kub ingot dov txoj kev.
3. Lub ingot forging thiab dov txoj kev tsuas yog siv nyob rau hauv ob peb qhov tshwj xeeb, xws li tooj liab alloy slabs nrog siab zog thiab siab conductivity.Lub plasticity ntawm ingot yog txhim kho los ntawm kub forging;qhov chaw hla ntu kuj tuaj yeem nthuav dav los ntawm kev ntxhov siab los tsim cov xwm txheej kom ntseeg tau tias qhov txias deformation ua tus nqi;cov kev taw qhia ntawm cov khoom tiav kuj tuaj yeem txhim kho los ntawm kev hloov cov kev taw qhia forging, thiab lwm yam.Cov txheej txheem ntawm tooj liab alloy daim ntawv, sawb thiab ntawv ci yog tsim los ntawm kub dov, milling, txias dov, kho cua sov, deg tu, ncab, khoov, thiab shearing.Ntawm lawv, kev tsim cov khoom siv hauv lub thawv tuaj yeem tau txais los ntawm electrolysis ntxiv rau kev ua haujlwm siab.
