Thaum koj muaj qhov project engineering, nws yog ib qho tseem ceeb rau xaiv cov khoom lag luam steel uas haum rau koj. Ntau hom hlau tsim cov khoom lag luam nrog cov ntaub ntawv thov. Kev tsim khoom thiab kev tsim qauv txheej txheem ntawm kub {{2} {rolled thiab txias} {rolled steel kev cuam tshuam rau tag nrho cov kev ua tau zoo ntawm cov hlau.
Xav tau high -} zoo kub lossis txias rolled steel rau koj txoj haujlwm tom ntej?
Dab tsi yog qhov sib txawv ntawmKub -} rolled steelthiabtxias -} rolled steel? Nkag siab cov teeb meem no tuaj yeem pab cov lag luam txuag nyiaj tau ntau ntau!
Cia peb ua ib qho kev sib tw ua ntej: kub dov steel yog zoo li freshly ci pancakes, mos thiab yooj yim rau cov duab; Txias cov hlau yog zoo li lub ncuav mog qab zib txias, nyuaj thiab smoother. Txawm hais tias tib cov hmoov nplej (steel billet) yog siv, cov txheej txheem kev ua tau txawv, ua rau cov khoom sib txawv ntawm cov khoom lag luam.
Yuav ua li casKub -} rolled steelLos txog?
Ua kom sov cov hlau billet mus rau saum toj 1200℃thiab nias nws mus rau hauv ib lub phaj steel nrog lub zeb dov thaum nws hloov liab. Qhov no zoo li Kneading Roj Hmab Av, cov hlau tshwj xeeb yog mloog ntawm cov kub thiab tuaj yeem ua tau sai.
Txias Rolled Steelyog ua si nrog kev khiav thev naus laus zis
Tom qab kub dov steel txias cia, nws yuav yog precision dov dua nyob rau hauv chav tsev kub. Ib yam li siv hlau rau cov khaub ncaws ncaj, saum npoo ntawm cov hlau phaj ua nyob rau hauv txoj kev no tuaj yeem saib hauv daim iav, nrog tus tuab tuab yuam kev zoo dua li cov plaub hau ntawm plaub hau.
Xim: Kub Rolling thiab Dhuav Txias thiab tsuas yog kev ua txoj hauv kev, thiab tsis muaj dab tsi ua nrog qhov zoo ntawm cov hlau nws tus kheej. Zoo li tib daim nqaij tuaj yeem kib, do kib, thiab kib, cov hau kev tsuas yog sib txawv
Kub - rolled steel: ib qho yooj yim piav qhia
Kub -} dovPuas yog cov txheej txheem siv nyob rau hauv cov hlau mills uas cov hlau yog dov thiab puab thaum nws kub heev, uas ua rau nws muaj peev xwm los tsim cov roj ntau npaum li cas.
Tom qab tau zoo li tus kheej, cov hlau tau tso cai kom txias qeeb qeeb ntawm chav sov. Qhov no maj mam txias, hu ua kev ntxhov siab sab hauv uas tuaj yeem tshwm sim thaum steel txias dhau lawm (zoo li hauv quenching) lossis thaum nws yog qhov tawv los ntawm kev ua tshuab.
Ib qho poob qis ntawm kub - rolling yog tias raws li cov hlau txias, nws shrinks tsis ncaj. Qhov no txhais tau tias cov khoom kawg yuav tau muaj tsawg dua qhov ntev dua thiab cov duab piv rau lwm txoj kev.
Lwm tus yam ntxwv ntawm kub - rolled steel yog nws cov ntxhib thiab me ntsis nro av. Qhov kev ntxhib los mos yog qhov tshwm sim ntawm kev ua kom rov cuam tshuam nrog cov pa oxygen ntawm qhov kub. Yog tias ib qho smoother saib lossis zoo dua qub yog xav tau, ntsuas tau muab tshem tawm los ntawm cov txheej txheem xws li:
Pickment - kho cov hlau uas muaj kua qaub kom ntxuav cov nplaim dej.
· Sib tsoo - siv abrasives kom du nws.
· Saltland {- blasting - blasting nto nrog cov xuab zeb lossis lwm yam.
Vim tias cov khoom no,Kub -} rolled steelMuaj tshwj xeeb tshaj yog pab tau nyob rau hauv cov ntawv thov uas siab qhov tseeb thiab zoo meej tsos tsis yog qhov kev txhawj xeeb tseem ceeb. Nws muaj zog, nqi -}}}}}}} Siv tau zoo, thiab siv dav hauv cov txheej txheem thiab kev lag luam xws li:
Track kev tsheb ciav hlau
{{- kab teeb (siv hauv kev tsim kho)
Tshuab ua liaj ua teb
Daim ntawv hlau (feem ntau siv hauv kev tsim khoom)
· Automotive thav lug
Nws kuj yog pom hauv kev tsim cov thav ntawv, cia lub hauv paus, thiab lwm yam hnyav - teeb meem ntau dua ib qho kev ua tiav.
Txias - rolled steel: ib qho yooj yim piav qhia
Tsis zoo li kub - rolled steel {{{1} {rolled steel yog ua tiav ntawm chav sov {}} tsis muaj cua sov heev. Lub npe tuaj yeem ua tsis tau me ntsis, vim nws tsis yog khov los yog chilled; Hloov chaw, "khaub thuas" tsuas yog txhais tau tias cov hlau tsim muaj cov ntaub pua uas siv tau rhuab.
Txoj kev no tau nce ntxiv lub zog ntawm cov hlau -} los ntawm ib qho kev hu ua strain hardening, qhov twg siab ua rau cov steel muaj zog thiab nyuaj.
Cov txheej txheem cuam tshuam ntau theem, xws li:
Nkawv nroo poob nkoj
· Semi -} txhij
· Sizing
· Rouging
· Tiav
Cov kauj ruam no pab tau tsim cov qauv hlau kom raug thiab nrog cov chaw zoo dua qub.
Vim tias txias - rolling ua tiav tsis muaj cua sov, tus hlau tsis shrink thaum txias. Qhov no tso cai rau kev tswj ntau dua tig dhau ntawm cov duab zaum kawg thiab qhov ntev, ua rau nws zoo tagnrho rau cov phiaj xwm qhov twg precision tseem ceeb.
Lwm qhov zoo dua yog nws txoj kev du thiab txaus nyiam nto. Txias - rolled steel feem ntau zoo nkaus li huv thiab yog zoo-}}}}}} d haum rau cov ntawv thov uas yog qhov tseem ceeb.
Txawm li cas los xij, ib qho kev txwv yog tiastxias -} rolled steelfeem ntau tsuas yog muaj nyob rau hauv cov duab yooj yim xws li:
Hauv cov plaub ntug
Puag ncig
Tsev tiaj
thiab lawv cov kev sib txawv me ntsis.
Cov siv sib xws li suav nrog:
· TEJ TUB THIAB CARMS
Put bods
Cov khoom siv hauv tsev (zoo li cov tshuab ntxhua khaub ncaws thiab tub yees)
Panels A-as Cov Khaub Ncaws
Tog hluav taws xob hluav taws xob (rooj zaum, txee, khoom)
· Aerospace cov txheej txheem sib xyaw (rau cov dav hlau thiab lub ntuj ceeb tsheej)
Nws tseem muaj dav siv hauv cov khoom siv hluav taws xob, cov khoom siv hluav taws xob, thiab ntau tus neeg siv khoom siv qhov uas xav tau ua tiav zoo.
