Cov Mills raj yog cov khoom siv tseem ceeb hauv kev tsim khoom lag luam, siv rau kev ua ntau hom tubular khoom. Cov kev ua tau zoo ntawm cov mill mills yog qhov tseem ceeb cuam tshuam los ntawm kev siv vuam ua haujlwm, tshwj xeeb yog TIG (Tungsten Inert Gas) thiab ntshav vuam. Tsab ntawv no tshawb txog cov kev cuam tshuam ntawm cov kev vuam hlau ntawm kev ua yeeb yam ntawm Raj mills, qhia txog lawv cov txiaj ntsig, thiab qhov cuam tshuam uas cuam tshuam rau lawv txoj kev ua haujlwm.
1. Txheej txheem cwm ntawm ntawm cov neeg siv raj ua haujlwm
Cov Mills raj yog tsim los tsim cov puag ncig, square, lossis cov kab plaub hau thiab cov kav dej los ntawm coiled hlau ib daim. Lub sijhawm ua haujlwm ntsig txog uncoiling lub steel sawb, tsim nws mus rau hauv lub raj ci yas, thiab tom qab ntawd sizing thiab txiav lub raj rau lub sijhawm xav tau. Kev ua tau zoo thiab zoo ntawm cov khoom kawg yog nyob ntawm ntau yam khoom, suav nrog tsim cov raj zeb, cov khoom siv ntawm cov txheej txheem hlau, thiab cov kev siv vuam siv.
Qhov tseem ceeb ntawm cov raj mills
Lub Cheebtsam tseem ceeb ntawm cov raj zeb ua ntej:
- Lub chaw nres tsheb uncoiling: uncoils tus hlau sawb los ntawm ib tug coil.
- Ua Tshooj Ntu: Duab lub tiaj tiaj tiaj tiaj mus rau hauv lub raj.
- Vuam ntu: Koom nrog cov npoo ntawm lub raj siv vuam cov tswv yim.
- SITING Seem: ntau thiab tsawg lub raj rau cov cheeb tsam uas xav tau.
- Tej seem: txiav lub raj rau qhov yuav tsum tau ntev.
Qhov tseem ceeb ntawm Vuam hauv Raj Zeb Ua Haujlwm
Kev ua haujlwm vuam yog qhov ua haujlwm tseem ceeb hauv cov mills mills thaum nws txiav txim siab ncaj ncees thiab lub zog ntawm cov khoom kawg. Qhov zoo tshaj ntawm Weld sib koom tes cuam tshuam rau cov khoom siv tshuab ntawm lub raj, suav nrog nws lub zog tensile, ductility, thiab kev tiv taus rau corrosion. Yog li ntawd, xaiv cov txheej txheem vuam tsim nyog yog qhov tseem ceeb rau kev ua cov hlab loj-ua kom sib haum xeeb.
Hom hlab thiab lawv cov kev siv
Raum mills tsim ntau hom kev ntawm cov hlab, suav nrog:
- Kev Tsim Kho Vaj Teeb: Siv hauv kev tsim kho thiab cov phiaj xwm nruab nrog.
- Cov leeg hlau tshuab: siv nyob rau hauv chaw tsim khoom machinery thiab khoom siv.
- Roj thiab roj hlab: siv nyob rau hauv cov roj thiab roj kev lag luam rau kev thauj khoom ntawm cov kua dej.
- HVAC hlab: siv hauv cua sov, qhov cua, thiab cua txias.
Txhua hom ntawm lub raj muaj cov kev qhia tshwj xeeb hauv cov khoom siv cov khoom thiab vuam zoo, uas cuam tshuam kev xaiv ntawm cov tshuab raj.
2. VUAM cov txheej txheem hauv cov mills
Raj mills feem ntau siv ob lub vuam cov tswv yim: Tig (Tungsten Inert Roj) Vuam thiab Ntshav Vuam. Ob txoj kev muaj lawv cov txiaj ntsig zoo thiab raug xaiv raws li cov kev xav tau ntawm lub raj yog tsim tawm.
Tig vuam: Qhov zoo thiab txwv
Tig vuam, Kuj tseem hu ua Roj Tungsten Arc Vuam (GTaw), siv cov tsis muaj neeg siv tungsten elegsten elegsten eldsten eld. Lub cheeb tsam weld yog tiv thaiv los ntawm kev paug los ntawm cov roj inert, feem ntau argon lossis helium.
Qhov Zoo:
- Cov Khoom Siv Zoo Tshaj Plaws Cov Ntawv: Tig Vuam Ua Rau Cov Khoom Siv Huv Si, muaj zog, thiab meej meld nrog tsawg heev.
- Versatility: Nws tuaj yeem siv rau ntau cov ntaub ntawv, suav nrog cov hlaus tsis quav, txhuas, thiab cov roj av alloys.
- Tswj: muab kev tswj zoo tshaj cov lus tawm tshiab thiab pas dej ua ke weld.
Txwv:
- Ceev: Tig vuam yog qeeb qeeb piv rau lwm txoj kev vuam, uas tuaj yeem cuam tshuam rau cov khoom lag luam ntawm cov raj zeb.
- Kev Txawj Ntse: Yuav tsum muaj theem siab ntawm kev txawj thiab kev paub los ntawm tus neeg teb xov tooj.
Plasma Vuam: Qhov zoo thiab cov kev txwv
Ntshav vuam yog qhov sib txawv ntawm Tig vuam uas siv lub arc txwv los tsim cov ntshav kub hnyav. Hom no yog tshwj xeeb tshaj yog tsim nyog rau vuam nyias cov ntaub ntawv.
Qhov Zoo:
- Kev siv hluav taws xob siab: Plasma Vuam yog sai dua li Tig vuam, uas tuaj yeem nce kev tawm ntawm lub raj zeb.
- Nkag mus tob: Nws muab qhov tob tob tob, ua rau nws zoo tagnrho rau cov khoom tuab tuab.
- Txoj kev tswj hwm zoo: Muaj kev tswj kom zoo ntawm lub pas dej weld thiab cov lus tawm tshiab.
Txwv:
- Cov khoom siv them nqi: Plasma vuam cov khoom siv yog kim kim dua li cov khoom siv vuam.
- Cov txheej txheem nyuaj: Cov txheej txheem yog cov khoom siv ntau dua thiab yuav tsum tau cov cuab yeej siv ntau dua.
Yam cuam tshuam rau kev xaiv vuam cov txheej txheem
Qhov kev xaiv ntawm TIG thiab ntshav vuam yog nyob ntawm ntau yam, suav nrog:
- Cov khoom siv thiab cov tuab: cov ntaub ntawv tuab tuab yuav xav tau ntshav vuam rau kev nkag mus tob.
- Yuav tsum muaj Weld Zoo: Rau cov zoo, meej welds, Tig vuam yuav nyiam.
- Ntau lawm ceev: yog ntau dua cov kev nrawm nrawm yog qhov yuav tsum tau, ntshav vuam yuav yog qhov kev xaiv zoo dua.
- Cov kev txiav txim siab tus nqi: Cov nqi siv thiab cov nqi ua haujlwm yuav cuam tshuam rau kev xaiv vuam cov txheej txheem.
3. Kev cuam tshuam ntawm TIG thiab Ntshav Vuam ntawm Raj Zeb Ua Haujlwm
Kev ua yeeb yam ntawm Raum mills yog cuam tshuam loj heev los ntawm kev xaiv vuam txheej txheem. Seem no tshawb nrhiav seb yuav ua li cas tsov thiab ntshavfa vuam cuam tshuam cuam tshuam rau ntau yam ntawm cov zeb ua haujlwm.
Weld zoo thiab nws qhov tseem ceeb
Qhov zoo tshaj ntawm Weld sib koom ua ke yog qhov tseem ceeb rau cov qauv kev cai ntawm lub raj. Cov ntaub ntawv zoo yog cov yam ntxwv los ntawm:
- Tsis xws li: tsis xws luag xws li porosity, kab nrib pleb, thiab undercut tuaj yeem ua rau muaj kev tiv thaiv weld.
- Cov ris tsho sib xyaw: zoo ib yam Weld hlaws duab thiab loj kom ntseeg tau cov khoom siv tshuab hluav taws xob uas tsis tshua muaj zog.
- Tsawg heev distortion: cov khoom siv zoo tsawg tsawg ntawm cov raj ntawm lub raj thaum lub sijhawm vuam.
Kev cuam tshuam rau ntawm cov khoom lag luam ceev thiab ua haujlwm
Qhov kev xaiv ntawm cov txheej txheem vuam tuaj yeem cuam tshuam ntau cov khoom siv ceev thiab ua haujlwm ntawm cov raj zeb:
- Tige vuam, thaum ua cov khoom siv zoo, yog qeeb qeeb thiab yuav txo cov nrawm tshaj qhov nrawm.
- Plasma vuam, ntawm qhov tod tes, muaj ntau dua vuam ceev, nce kev tawm ntawm lub raj zeb.
- Txhim kho kev ua tau zoo tuaj yeem ua rau cov nqi txuag tau thiab muaj txiaj ntsig zoo rau cov tshuab tuam ntxhab.
Kev Siv Zog thiab Tus Nqi Hluav Taws Xob
Kev noj hluav taws xob yog qhov tseem ceeb tshaj plaws hauv kev ua haujlwm ntawm kev ua haujlwm ntawm Raj Mills:
- Tig vuam feem ntau noj ntau lub zog vim nws txoj kev rov ua haujlwm qeeb dua.
- Plasma vuam, txawm hais tias nws cov cuab yeej siv siab dua, tuaj yeem muaj zog ntau dua vim nws qhov kev tawm suab nrawm dua thiab qis dua kev kub ceev.
- Txo kev siv hluav taws xob tsis tsuas yog cov nqi qis qis tab sis kuj txo qis qhov kev cuam tshuam ib puag ncig ntawm cov raj zeb ua haujlwm.
Nyhuv rau cov khoom siv tshuab ntawm welded leeg
Cov txheej txheem vuam siv nyob rau hauv cov mill mills cuam tshuam rau cov khoom siv me me ntawm Welded Tubes:
- Tig Vuam ua cov MicrDs Microstruction thiab cov kws kho hluav taws xob zoo, ua kom haum rau cov ntawv thov kom muaj zog thiab du.
- Plasma Vuam vuam muab tob nkag thiab tuaj yeem siv rau vuam tuab cov ntaub ntawv, tab sis tej zaum yuav ua rau coarser microstructure thiab sib txawv cov khoom siv.
- Nkag siab txog kev cuam tshuam ntawm vuam ntawm cov tshuab khoom siv yog qhov tseem ceeb rau kom ntseeg tau tias lub raj welded ua kom tau raws li cov qauv tshwj xeeb thiab cov qauv.
4. Xaus
Kev xaiv ntawm cov txheej txheem welding, txawm hais tias tsov lossis ntshav, muaj qhov cuam tshuam tseem ceeb ntawm kev ua haujlwm ntawm cov raj mills. Thaum Tig vuam muaj cov welds zoo thiab versatility, nws yuav txo cov khoom siv ceev thiab ua kom muaj zog siv hluav taws xob. Plasma vuam, ntawm qhov tod tes, muab kev siv vuam nrawm dua thiab tob nkag mus tab sis yuav ua rau sib txawv cov khoom siv. Cov kws tsim khoom yuav tsum ua tib zoo saib cov cuab yeej siv vuam kom ua kom tau zoo ntawm lawv cov raj thiab ua kom tau raws li cov ntawv thov tshwj xeeb.
