Muab kauv cov yeeb nkab yog ib qho loj- dexeter steel yeeb nkab los ntawm cov kauv cov txheej txheem. Nws yog dav siv hauv cov phiaj xwm kev nyab xeeb hauv cov roj hauv cov roj, roj, tshuaj, thiab cov khoom txuag dej. Cov txheej txheem tsim khoom feem ntau feem ntau koom nrog cov khoom tseem ceeb xws li txheej txheem tseem ceeb thiab shearing, vuam, vuam, vuam, thiab kuaj thiab kuaj zoo. Txhua kauj ruam tshwj xeeb cuam tshuam qhov zoo thiab ua tau zoo ntawm cov khoom kawg.
1. Cov Khoom Siv Khoom Raw
Thawj cov khoom siv raw rau kauv steel yeeb nkab yog kub}} {{{{- lub zog steel. Ua ntej ntau lawm, cov hlau coils yauv tshuaj ntsuam xyuas, xws li cov kab nrib kev ntsuas tshuaj (xws li cov qauv tshuaj ntsuam (xws li GB / T 9711 thiab API 5L).
2. Sawb Leveling thiab shearing
Vim tias cov sawb yuav khoov los yog tsis nco qab thaum lub sijhawm tsheb thauj mus los lossis dov, nws yuav tsum yog cov txheej txheem ua tau raws li kev yuav tsum tau ua. Tom qab, nyob ntawm cov specifications ntawm kauv steel yeeb nkab, cov sawb yog sheared mus rau qhov kev xav tau ntev uas siv ib lub suab shear kom ntseeg tau kev sib txuas ntxiv thaum ua tiav.
3. Muab kauv sib
Txoj kev sib sau yog cov tseem ceeb ntawm cov kauv yeeb nkab steel yeeb lawm. Cov kab txaij yog maj coiled rau hauv kauv raj los ntawm lub tshuab sib zog (feem ntau yog cov tswj hwm sab nraud (feem ntau tswj cov kev sib ntaus tshuab) thaum lub tshuab txuas ntxiv. Txoj kev sib sau tshuab cov rollers tau hloov kho ntawm lub kaum sab xis tshwj xeeb (feem ntau yog 1.5℃rau qib 3 degree) kom maj mam nqa cov sawb sawv ua ke thiab ua tus kauv ruaj khov. Thaum lub sij hawm tsim cov txheej txheem, sawb nro, nrawm, thiab cov menyuam cov raj suav, ncaj, thiab sib zog weld sib txawv.
4. VUAM Txheej Txheem
Muab kauv steel kav yog feem ntau welded siv submerged arc vuam (pom), uas tau muab faib ua ob kauj ruam: vuam vuam thiab sab nraud vuam.
Sab hauv Vuam: Ib Leeg {- xaim los yog ntxig hauv paus ntawm weld sab hauv cov yeeb nkab kom ntseeg tau tias kev nkag mus.
Sab nraud vuam: Ntau- xaim kaw (feem ntau yog twin lossis triple xov hlau) yog siv nyob rau sab nraud txhawm rau txhim kho lub zog vuam thiab ua kom muaj zog thiab zoo nkauj.
Vuam qhov tsis (xws li tam sim no, voltage, thiab nrawm) yuav tsum tau kho qhov tsis xws luag raws li porosity, thiab tsis muaj fusion. Qee qhov siab -}} xaus kauv steel kav tseem tseem tau siv lub siab ua ntej weld, ua raws li submerged rau lub arc vuam rau qib kawg weld.
5. Kev Kho Mob Weld
Tom qab vuam, Weld Seam yuav tsum tau ua tiav thiab tshuaj xyuas:
Weld Seam Sib Tsoo: Qhov no tshem tawm weld ntau dhau, tsim kom muaj kev hloov pauv ntawm Weld thiab cov khoom siv hluav taws xob, thiab txo cov khoom muaj kev ntxhov siab. Kev Kuaj Ultrasonic (ut): Tshawb nrhiav Welds rau sab hauv tej yam (xws li pores thiab nrib pleb).
X-ray Testing (RT): Performs non-destructive testing of critical areas to ensure weld quality meets standards.
6. Kev nthuav dav thiab ncaj
Txhawm rau tshem tawm cov kab hlau ntxhov siab thiab txhim kho cov kav hlau sib txawv, cov kauv steel kav feem ntau undergo nthuav dav (hydraulic lossis nthuav tawm cov yeeb nkab lub cev). Lawv yog ces ncaj qha los xyuas kom lawv tau raws li txoj haujlwm teeb tsa txoj haujlwm.
7. Lub sijhawm ua haujlwm thiab tshuaj xyuas
Nyob ntawm cov neeg xav tau cov neeg siv khoom, cov xaus ntawm kauv hlau kav yuav xav tau Beveling (rau vuam) lossis flange sib txuas). Thaum kawg, cov kav dej yauv tau kev soj ntsuam kev ua tau zoo, suav nrog:
Kev tshuaj ntsuam sab nrauv (txheej uas cov uas hla, phab ntsa thickness, thiab ovality);
Siab ntsuas (dej lossis cua siab sim kuaj xyuas cov siab tiv thaiv);
Anti - kev kho corrosion (xws li epoxy hmoov txheej lossis 3pe txheej los txhim kho corrosion tsis kam).
8. Sau npe thiab cov zaub mov xa tuaj
Tsim Nyog Kauv Khoom Siv Hlau Steel yog sau npe raws li cov qauv (xws li cov ntaub ntawv (specificaged, thiab muab ntau lawm backing ua ntej cov zaub mov xa tuaj mus rau lub vev xaib rau kev teeb tsa thiab siv.
Tag
Cov txheej txheem ntau lawm rau kauv hlau cov kav hlau cuam tshuam nrog ntau cov kauj ruam, thiab kev tswj hwm nruj heev los ntawm cov khoom raw los ua cov khoom tiav. Cov txheej txheem kev siv thev naus laus zis, suav nrog kev sib tw ua haujlwm, muaj kev cuam tshuam ntxiv, thiab tsis muaj peev xwm ntxiv ntawm cov khoom siv hlau kauv hauv cov khoom siv niaj hnub ua rau cov xa hluav taws xob niaj hnub.
