Ob. Cov txheej txheem ntau lawm cov ntsiab lus ntawm txoj kab uas hla loj lsaw steel yeeb nkab
1. Ua haujlwm ua ntej tsim
Cov khoom siv raw yog steel coils, vuam hlau, thiab flux. Yuav tsum tau mus dhau kev kuaj lub cev thiab tshuaj lom neeg ua ntej kev nqis peev. Cov pob qij txha ntawm cov hlau strips yog welded nrog monofilament los yog ob chav hlau submerged arc vuam. Tom qab lub raj steel yog dov, tsis siv neeg submerged arc vuam yog siv rau vuam.

2. Moulding txheej txheem
Lub tshuab hluav taws xob tiv tauj lub ntsuas hluav taws xob yog siv los tswj lub siab ntawm lub tog raj kheej compression ntawm ob sab ntawm lub conveyor kom ntseeg tau tias kev xa khoom zoo ntawm cov sawb. Lub tshuab tseem ceeb yog nyob ntawm qhov chaw. Yog li ntawd, kev hloov kho ntawm cov menyuam ntsug (tshwj xeeb tshaj yog ua ntej thiab tom qab lub taub hau) yuav tsum tau kuaj xyuas ntau zaus kom ntseeg tau tias qhov kev xa khoom nruj ntawm lub sawb. Khiav ntawm txoj kev teev tseg los ntawm cov txheej txheem thiab dhau qhov tsim meshing point. Kev tswj sab nraud lossis kev tswj sab hauv yob txoj kev yog siv los xyuas seb qhov perimeter, ellipticity, straightness, thiab lwm yam ntawm cov yeeb nkab steel ua raws li tus qauv yuav tsum tau ua. Yog tias nws tsis ua raws li qhov yuav tsum tau ua, nws yuav raug kho ntxiv mus txog thaum nws ua tau raws li qhov yuav tsum tau ua.

3. Vuam txheej txheem
Weld gap control device yog siv los xyuas kom meej tias qhov sib txawv weld ua tau raws li qhov xav tau ntawm vuam. Cov yeeb nkab txoj kab uas hla, tus nqi ntawm misalignment, thiab qhov sib txawv weld yog txhua yam nruj me ntsis tswj. Qhov zoo ntawm kev sib sau seam yuav tsum tau soj ntsuam tas li, thiab nws yuav tsum pom tias cov npoo tsis zoo, qhib seams, thiab lwm yam. Fine-tune lub kaum sab xis ntawm lub rear qag nyob rau hauv lub sij hawm los xyuas kom meej qhov zoo ntawm kev sib sau; Thaum qhov xwm txheej yog txawv txav, xyuas seb qhov kev ua haujlwm dav ntawm lub sawb puas, qhov kev kho ua ntej ntawm lub ntug, txoj hauj lwm ntawm txoj kab xa khoom, lub kaum sab xis ntawm cov menyuam me, thiab lwm yam tau hloov, thiab kho cov kev ntsuas hauv lub sijhawm. Hebei ncaj seam steel yeeb nkab manufacturers tam sim no siv lub tebchaws United States Lincoln vuam tshuab rau ib tug hlau los yog ob chav hlau submerged arc vuam nyob rau hauv thiaj li yuav tau ruaj khov vuam zoo. Ncaj seam steel yeeb nkab manufacturers yuav tsum tsis tu ncua saib xyuas qhov zoo ntawm kev sib sau cov pob qij txha, thiab yuav tsum tam sim ntawd fine-tune lub rear qag lub kaum sab xis kom lub molding zoo nyob rau hauv cov ntaub ntawv ntawm misaligned npoo, qhib seams, thiab lwm yam.; yog tias cov xwm txheej txawv txav, xyuas qhov dav ntawm kev ua haujlwm, ntug kev khoov ua ntej, thiab xa cov hlau sawb. Txawm hais tias muaj kev hloov pauv hauv txoj haujlwm ntawm txoj kab, lub kaum sab xis me me, thiab lwm yam, thiab siv cov kev ntsuas kom raug raws sijhawm.

4. Kev kuaj xyuas
Cov welded welds tau soj ntsuam tag nrho hauv online los ntawm lub tshuab tsis siv neeg ultrasonic tsis zoo los xyuas kom meej 100% kev tshuaj xyuas tsis muaj kev puas tsuaj ntawm cov kauv vuam. Yog tias muaj qhov tsis xws luag, lawv yuav raug ceeb toom thiab pleev xim rau. Cov neeg ua haujlwm tsim khoom yuav kho cov txheej txheem tsis tu ncua txhua lub sijhawm kom tshem tawm qhov tsis xws luag hauv lub sijhawm. Thaum lub nominal txoj kab uas hla D ≥ 426mm, qhov tsis xws luag ntawm cov yeeb nkab steel yuav tsum tau muab ntxuav thiab kho sab hauv; Thaum D ≤ 426mm, qhov tsis xws luag sab hauv tuaj yeem raug tshem tawm los ntawm sab nraud los ua cov vuam sab nraud. Tom qab kho vuam, cov vuam yuav tsum yog hauv av thiab cov phab ntsa seem tom qab kev sib tsoo yuav tsum nyob rau hauv cov txheej txheem phab ntsa thickness kam rau ua. Ua ntej kho cov welded steel yeeb nkab rau hauv cov txheej txheem tom ntej, nws yog ib qho tsim nyog yuav tsum tau ua tib zoo tshuaj xyuas seb puas muaj ib qho kev ploj lossis tsis muaj qhov tsis zoo ntawm cov yeeb nkab steel thiab kho nws ua ntej mus rau cov txheej txheem tom ntej. Lub pob tw-welded pob qij txha ntawm lub pob tw-welded pob qij txha thiab cov kauv welds tau kuaj xyuas los ntawm X-ray TV lossis zaj duab xis. Txhua cov yeeb nkab tau kuaj hydrostatically thiab lub siab yog radial kaw. Kev ntsuas siab thiab lub sijhawm yog nruj me ntsis tswj los ntawm cov yeeb nkab steel hydraulic siab ntsuas cov cuab yeej. Cov ntsuas ntsuas tau raug luam tawm thiab kaw.

5. Ntim tawm ntawm lub tsev qiv ntawv
Pipe kawg machining, kom lub ntsej muag kawg perpendicularity, zawj lub kaum sab xis thiab blunt ntug yog tswj kom raug. Cov cua plasma cutter txiav cov raj steel rau hauv ib tus neeg. Tom qab cov hniav yog blunt los yog puas lawm, cov hniav tshiab yuav tsum tau hloov tam sim ntawd. Cov hniav tshiab yuav tsum tau sharpened nrog ib lub pob zeb ua ntej siv, thiab nws yuav tsum tsis txhob yuav av nrog ib tug grinder. Tom qab cov hniav tawg lawm, nws tuaj yeem siv tau tom qab siv cov pob zeb sib tsoo dua tom qab sib tsoo nrog lub grinder.
