Kev kos duab hlau yog cov txheej txheem uas siv cov siab los deform cov khoom siv hlau hauv cov pwm kom tsim nyog. Hauv cov txheej txheem no, tsim kev xaiv tsim nyog ua ke thiab kev siv thev naus laus zis yog qhov tseem ceeb ntawm kev ua kom zoo tshaj plaws ntawm cov khoom kawg, kev tswj hwm ntau lawm thiab raug tswj hwm. Cov hauv qab no yog kev soj ntsuam ib qho kev xaiv ntawm cov khoom xaiv thiab kev ua cov txheej txheem hauv kev kos duab hlau.
Kawm paub ntau ntxiv txog kev kos hlau: kev xaiv thiab ua cov txheej txheem
Ua ntej, hais txog cov khoom xaiv ntawm tensile
Hauv cov txheej txheem kos duab hlau, cov yam ntxwv ntawm cov khoom ncaj qha cuam tshuam qhov zoo ntawm cov khoom tiav thiab cov txheej txheem ntau lawm. Cov khoom sib txawv hlau muaj cov khoom sib txawv xws li kev ncab, ductility thiab tensile muaj zog, yog li tseem ceeb kom xaiv cov khoom raug.
1. Hom thiab cov yam ntxwv ntawm cov khoom siv uas nquag siv
Stainless hlau
Nta: Stainless hlau muaj zoo corrosion tsis kam, muaj kub ua hauj, thiab muaj zog txhua yam muaj zog. Nws yog qhov tsim nyog rau cov khoom lag luam nrog cov kev xav tau ntawm cov tsos thiab corrosion tsis kam, xws li cov khoom siv hauv chav ua noj, ntu tsheb, thiab lwm yam.
Hom kev nquag: 304 stainless hlau, 430 stainless hlau, thaum muaj ntau lub durability yog tsim nyog rau kev siv nrog cov kev xav tau ntawm corrosion.
2. Qhov tseem ceeb rau kev cuam tshuam rau cov khoom siv xaiv
Ductility thiab cov yas: Hlau ncab yuav tsum muaj cov khoom siv kom muaj kev sib tw zoo thiab muaj kuab yas, yog li tsis muaj qhov tawg lossis tawg nrawm thaum lub sijhawm ncab. Qhov zoo dua qhov ductility ntawm cov khoom, qhov yooj yim dua nws yog kom sib sib zog nqus.
Lub zog tensile: tensile lub zog yog lub peev xwm ntawm cov khoom siv tensile, thiab lub zog ntau dua muaj qhov ua tiav tau txaus kom txaus thiab tsis muaj zog thaum siv.
Cov Khoom Thickness: Cov tuab ntawm cov khoom siv kuj cuam tshuam rau kev nyuaj ntawm kev kos duab. Thicker cov ntaub ntawv feem ntau yuav tsum muaj zog ntau dua los ncab, yog li txo cov duab nrawm lossis nrawm dua cov qhab nia yog qhov tsim nyog.
Cov kev kho deg thiab corrosion resistance: qee cov kev siv (xws li cov khoom siv kho mob, yuav tsum tau cov khoom siv kho mob), thiab cov ntaub ntawv txhuas lossis cov ntaub ntawv txhuas cov ntaub ntawv ntau dua.
Tus nqi tswj: Nyob rau ntawm kev ua tiav ntawm lub rooj sib tham txog cov khoom siv ua haujlwm, sim xaiv cov ntaub ntawv siv tau nqi kom tsis txhob siv cov khoom siv ntau ntawm cov nqi ntau dhau.
Thib ob, hlau kos duab ua tshuab
Cov txheej txheem kev kos duab hlau feem ntau ua cov khoom siv hlau mus rau hauv cov duab yam xav tau los ntawm ntau cov kauj ruam kev ua. Txhawm rau kom tau txais cov khoom lag luam siab tiav, nws yog qhov tsim nyog los siv cov cuab yeej siab ua ke nrog cov cuab yeej tsim nyog.
1. Cov qauv theem pib ntawm cov txheej txheem kos duab
Kev sib sib zog nqus duab
Kev sib sib zog nqus teeb duab yog txheej txheem uas cov ntawv hlau yog rub tawm mus rau hauv cov hollow qhov chaw nrog ntau qhov tob dhau los ntawm kev tawm tsam loj. Nws yog qhov tsim nyog rau tsim cov kab loj nrog cov duab sib txawv, xws li cov roj nruas roj, cov khoom tawg thiab yuav tsum muaj cov khoom loj dua.
Ib qho teeb duab (kos duab)
Kev kos duab yog tsim nyog rau kev tsim cov hlau ntiav lossis qhov tob thiab cov khoom vaj khoom siv, cov khoom siv hauv tsev, thiab lwm yam, thiab lwm yam.
Compound kos duab
Composite kos duab yog hais txog kev siv cov pwm los yog ntau lub tshuab los tsim cov duab ntawm cov txheej txheem hauv ib txheej txheem kos duab. Tus txheej txheem no yog tsim nyog rau ntu uas yuav tsum muaj ntau qhov tob lossis cov duab, feem ntau xav tau cov tshuab hluav taws xob siab tsim muaj peev xwm.
2. Cov khoom siv tseem ceeb thiab thev naus laus zis
Nqus xovxwm
Daim duab xovxwm (tseem hu ua lub cav sib nqus) yog cov cuab yeej tseem ceeb ntawm cov txheej txheem kev kos duab hlau, feem ntau tsav los ntawm kev sib xyaw ua ke rau deform nyem cov ntawv hlau. Raws li cov nplai ntawm kev tsim khoom, kev kos duab tuaj yeem faib ua ib qho kev sib sau ua ke thiab ntau lub tshuab ua ntau.
Cov Tshuab Automation thiab Hlau
Nrog rau txoj kev txhim kho kev ntse, ntau dua thiab ntau cov kev ua haujlwm hlau siv cov tshuab hlau thiab cov neeg hlau kom txhim kho kev ua haujlwm tau ntau thiab raug. Cov neeg hlau tuaj yeem ua tiav txoj haujlwm ntawm cov chaw thau khoom tsis siv neeg, tsis siv neeg, nrhiav kom tau, hnav khaub ncaws thiab.
Pwm Tsim thiab Txhim Kho
Tus tsim ntawm cov tuag ncaj qha cuam tshuam cov khoom lag luam zoo hauv cov txheej txheem kos duab. Cov pwm zoo uas tau ua kom tau raws li cov cai ntawm cov hlau ntws, faib tawm, stripping thiab li ntawd. Kev ua kom zoo ntawm cov pwm tsim thiab cov txheej txheem txheej txheem los ntawm cov sim kev sim, xws li cov kev ntsuas zoo, tuaj yeem txo cov peev xwm thiab txhim kho ntau lawm.
Txheej txheem Multipass Ncab Ncab Ncej
Hauv kev tsim cov khoom ntawm qee qhov nrog cov duab nyuaj, nws yog feem ntau nyuaj ua kom tiav cov kev tsim zoo tshaj plaws nrog ib qho kev kos duab. Yog li no, ntau-kis cov teeb duab ntau yog siv los ua tiav qhov kev tsim kom tiav tiav los ntawm maj mam kos duab nyob rau theem. Lub siab thiab nrawm ntawm txhua cov txheej txheem yuav tsum tau ua kom meej kom ntseeg tau qhov tseeb thiab xwm yeem ntawm cov khoom kawg.
3. Kev kho cua sov thaum lub sijhawm ncab
Muaj qee kis, cov ntaub ntawv hlau xav tau kev kho cua sov kom txhim kho lawv cov yas thiab txo qhov kev pheej hmoo ntawm cov kab nrib pleb thaum nthuav dav. Cov Kev Kho Tshav Kub Cua Sov muaj xws li:
Annealing: los ntawm cov khoom cua kub rau ib qho kub thiab txias nws maj mam, tshem tawm sab hauv kev ntxhov siab thiab txhim kho kev sib cav sab hauv thiab kev sib zog ntawm cov khoom siv.
Li qub: Los cua sov cov hlau rau qhov tsim nyog kub thiab cua txias, cov qauv uas muaj cov nplej ntawm cov khoom siv tau txhim kho, ua rau nws muaj ntau.
Kev kho cua sov tsis tsuas pab los txhim kho txoj kev tsim kom zoo, tab sis kuj tseem yuav zam cov khoom siv tsis zoo thiab ua kom dhau los ua kev ua tom ntej.
Thib peb, kev xaiv cov khoom siv thiab kev siv thev naus laus zis
Xaiv cov ntaub ntawv zoo thiab kev ua cov txheej txheem, thiab hloov kho cov txheej txheem, thiab siv tau yooj yim raws li kev xav tau kev tsim khoom, yog tus yuam sij kom ntseeg tau tus txheej txheem hlau du. Nov yog qee cov qauv tshwm sim:
Stainless hlau kos duab: rau cov ntaub ntawv stainless hlau, vim tias nws cov kev ua kom zoo nkauj siab thiab siab tau txhim kho los ntawm polishing lossis sandblasting ntawm ib theem tom qab.
Aluminium Alloy Ncab: Lub ductility ntawm txhuas alloy yog qhov zoo, haum rau tob ncab hauv ntau qhov kev sib tw thiab lub zog loj. Rau txhuas alloy daim hlau nrog loj tuab, annealing kev kho yog xav tau los txhim kho cov qauv.
Titanium alloy tensile: lub zog siab thiab cov kua nplaum ntawm titanium alloys, nws yog feem ntau tsim nyog los tsim kho cov pwm thiab tswj lub tensile kom tsis txhob tawg.
Suav
Cov txheej txheem teeb tsa hlau ua lub luag haujlwm tseem ceeb hauv kev tsim, thiab ua kev tsim nyog ua ke ntawm cov khoom xaiv thiab kev siv thev naus laus zis yog tus yuam sij los ua kom zoo thiab txhim kho ntau dua. Los ntawm kev xaiv tsim nyog ntawm cov ntaub ntawv hlau uas haum, siv cov kev ua haujlwm tsim nyog, tuaj yeem txhim kho qhov tsis zoo ntawm cov hlau tensile, thiab ua kom tau raws li cov qhua tuaj noj mov
