Nyob rau hauv tsab xov xwm dhau los, peb tau qhia txog kev xaiv cov qauv ntawm ERW steel kav, weld seam zoo txoj kev txiav txim siab, thiab cov tswv yim kom tsis txhob muaj teeb meem zoo. Txawm li cas los xij, hauv kev tsim khoom siv hluav taws xob tiag tiag, ntau qhov teeb meem zoo tshwm sim tsis yog nyob rau "qib kev paub" tab sis thaum lub sijhawm ua tiav thiab nthuav dav tswj theem. Ua ke kev lag luam kev paub txog kev ua haujlwm, kab lus no ntxiv txheeb xyuas cov ntsiab lus yooj yim saib tsis taus hauv ERW steel yeeb nkab yuav khoom thiab muab cov kev daws teeb meem ntau dua.
1. Tus Txheej Txheem Tsis Txaus Siab: Dab tsi's Sau hauv Daim Ntawv Cog LusTsis yog Ib txwmDab tsi's Xa
Ib qho teeb meem tshwm sim hauv ERW steel kav kev yuav khoom yog: Daim ntawv cog lus qhia meej cov qauv, tab sis cov khoom xa tuaj tsis ua raws li lawv.
(1) Qhov sib txawv ntawm cov qauv qauv thiab cov ntsiab lus
Tib tus qauv feem ntau muaj cov ncauj lus kom ntxaws qhov sib txawv ntawm kev soj ntsuam piv, qhov ntev ntev, cov khoom kuaj, thiab lwm yam, nyob rau ntau xyoo thiab daim ntawv thov. Thaum lub sij hawm kev yuav khoom, qhia meej:
Ua kom tiav serial tooj ntawm tus qauv ua tiav
Seb puas muaj cov xwm txheej ntxiv ntxiv
Seb puas muaj qhov tshwj xeeb qhov yuav tsum tau ua
(2) Teb cov lus qhia
Qhia meej cov ntsiab lus tseem ceeb hauv kev pom zoo, xws li cov txheej txheem kev soj ntsuam vuam thiab cov kev ntsuas hydrostatic.
Thov ua kom tiav cov ntaub ntawv pov thawj zoo kom muab nrog cov khoom.
Ua thib peb- tog rov- tshuaj xyuas rau cov haujlwm tseem ceeb.
2. WeldSeamQuality Risk: "Vuam"Tsis sib npaug"Zoo Vuam"
Weld seam zoo yog qhov tseem ceeb ntawm kev ua haujlwm ntawm ERW steel kav, tab sis thaum lub sij hawm kev yuav khoom, weld teeb meem feem ntau zais los ntawm "kev tsim nyog tshaj plaws."
(1) Kev pheej hmoo zais
Lub weld seam zoo li tau txais, tab sis sab hauv fusion tsis txaus.
Kev hloov pauv hauv cov khoom siv vuam ua rau tsis zoo batch stability.
Cov qauv tsis sib xws nyob rau hauv qhov vuam cua sov- thaj tsam cuam tshuam.
Cov teeb meem no yuav tsis tshwm sim nyob rau lub sij hawm luv luv, tab sis cov kev pheej hmoo yuav maj mam nce nyob rau hauv ntev -lub sij hawm siab- bearing los yog complex ua hauj lwm tej yam kev mob.
(2) Teb cov lus qhia
Ua tib zoo saib seb cov chaw tsim khoom puas muaj qhov txuas txuas txuas txuas tsis tu ncua tswj kev muaj peev xwm.
Nkag siab yog tias ntawm - kev tshuaj xyuas kab vuam tau ua tiav.
Qhia meej qhov kev tshuaj xyuas qhov sib piv rau cov kav hlau siv hauv cov ntawv thov tseem ceeb.
Qhov teeb meem tsis txaus ntseeg ntawm Raw Material Batch Stability
Nyob rau hauv ntau qhov kev yuav khoom, sab nraud txoj kab uas hla, phab ntsa thickness, thiab weld ntawm steel kav raws li qhov yuav tsum tau, tab sis tag nrho cov kev ua tau zoo hloov pauv tshwm sim thaum siv. Lub hauv paus ua rau feem ntau yog nyob rau hauv tsis txaus raw khoom stability.
(1) Vim li cas Raw Materials tseem ceeb heev
ERW steel kav yog tsim thiab welded tsis tu ncua los ntawm steel strips. Kev hloov pauv hauv qhov muaj pes tsawg leeg thiab cov khoom tsis sib xws ntawm cov hlau nplaum ncaj qha cuam tshuam rau:
Vuam stability
Weld seam zoo
Kev sib raug zoo ntawm tag nrho - yeeb nkab zog
(2) Teb cov lus qhia
Ua ntej cov tuam txhab lag luam nrog cov khoom siv ruaj khov.
Thov steel strip cov ntaub ntawv pov thawj.
Rau qhov ntev - tej yaam num, ua tib zoo saib seb puas siv cov mills ruaj khov rau kev muab khoom.
4. Qhov teeb meem ntawm qhov ntev thiab qhov ncajQhia tawm ThaumKev teeb tsa
ERW steel kav feem ntau muaj qhov zoo ntawm qhov tseeb dua li cov kav hlau welded feem ntau, tab sis yog tias tsim thiab tswj qhov loj me tsis txaus, cov teeb meem hauv qab no tseem tuaj yeem tshwm sim:
Ntau dhau ovality
Localized dabtsi yog khoov
Cov yeeb nkab kawg bevel cuam tshuam lub pob tw
Cov teeb meem no yuav raug saib xyuas thaum lub sijhawm tshuaj xyuas lub Hoobkas tab sis yuav ua rau muaj teeb meem kev tsim kho ncaj qha thaum ntawm - qhov chaw teeb tsa.
Teb cov lus qhia
Qhia meej meej qhov yuav tsum tau muaj qhov ntev thiab ncaj nraim hauv cov txheej txheem kev yuav khoom.
Ua random soj ntsuam ntawm cov khoom siv lub cev es tsis txhob cia siab rau cov ntaub ntawv soj ntsuam.
Rau cov haujlwm uas xav tau siab precision, ua cov qauv kev pom zoo ua ntej.
CovQhov tseem ceeb ntawm Kev Tswj Xyuas Zoo Ua Ntej Anti-CorrosionKev kho mob
Hauv ntau qhov haujlwm, ERW steel kav tau txais kev tiv thaiv- kev kho corrosion tom qab tawm hauv lub hoobkas. Thaum nkag mus rau cov txheej txheem tiv thaiv -corrosion, weld seam lossis cov khoom siv hauv paus yuav raug them, ua rau kev kho tom ntej yuav luag tsis yooj yim sua.
Teb cov lus qhia
- Ua kom tiav tag nrho cov vuam thiab puv - yeeb nkab tshuaj xyuas ua ntej los tiv thaiv - corrosion.
- Zoo dua, kev tiv thaiv - corrosion thiab cov yeeb nkab tsim yuav tsum ua tiav los ntawm tib lub chaw tsim khoom.
- Khaws cov ntaub ntawv tshuaj xyuas kom tiav ua ntej los tiv thaiv -corrosion.
6. NqeKev ntsuam xyuas: Tus nqi qis Feem ntauXav txog"Tsis pom"Tus nqi
Muaj qhov pom tseeb tus nqi sib txawv hauv ERW steel yeeb nkab kev lag luam, feem ntau tshwm sim hauv:
- Qhov sib txawv ntawm qib raw khoom
- Variations nyob rau hauv weld soj ntsuam Proportions
- Cov txheej txheem tswj tau yooj yim
- Yooj yim ua raws li cov qauv
Hauv kev tsim khoom engineering, qhov kev pheej hmoo ntawm cov nqi qis- cov khoom siv feem ntau tsis tshwm sim thaum lub sijhawm xa khoom tab sis thaum lub sijhawm ua haujlwm.
Xaus
Raws li ib tug paub tab thiab dav siv hom welded steel yeeb nkab, ERW steel kav lawv tus kheej tsis muaj "zoo qib"; qhov sib txawv tiag tiag nyob rau hauv cov chaw tsim khoom muaj peev xwm tswj tau thaum lub sijhawm tsim khoom thiab tus neeg yuav khoom qhov kev txiav txim siab thaum lub sijhawm yuav khoom.
Los ntawm kev tsim kom muaj kev xaiv meej meej raws li cov qauv, cov khoom siv raw, vuam seams, kev tshuaj xyuas, thiab kev tswj xyuas kom meej, cov neeg yuav khoom tuaj yeem txo qhov kev pheej hmoo ntawm qhov project thiab ua kom lub sijhawm ntev - ruaj khov ntawm ERW steel kav hauv kev siv tiag tiag.
Hauv cov haujlwm ua tau zoo, xaiv cov tuam txhab lag luam nrog ntev -lub sij hawm tsom rau ERW steel yeeb nkab raug tsim, txhim kho cov txheej txheem zoo, thiab kev nplua nuj ntau lawm feem ntau muaj txiaj ntsig rau qhov project dua li kev sib piv cov nqi.
