Qhov tseem ceeb ntawm Sawn thiab Welded yeeb nkab nyob rau hauv niaj hnub Infrastructure, nyob rau hauv lub plawv ntawm Cangzhou, Hebei xeev, zaum ib tug steel zeb uas yog lub hauv paus ntawm cov steel yeeb nkab kev lag luam txij li thaum nws nrhiav tau nyob rau hauv 1993. Lub tuam txhab npog 350,000 square meters, boasts tag nrho cov cuab tam ntawm 680 lab RMB, thiab 68 neeg ua hauj lwm mob siab rau. Ntawm nws cov khoom siv ntau yam yog sawn thiab welded kav, ib qho tseem ceeb ntawm cov khoom siv niaj hnub no, tshwj xeeb hauv kev thauj mus los hauv av.
Hauv avPom Welded Yeeb NkabNws yog ib qho tseem ceeb rau kev thauj dej kom zoo thiab muaj kev ntseeg siab ntawm ntau qhov chaw. Lawv tsim cov pob txha ntawm peb cov txheej txheem niaj hnub no, ua kom cov dej huv tuaj txog hauv tsev, kev lag luam, thiab thaj chaw ua liaj ua teb. Kev xaiv cov khoom siv rau cov kav dej no yog qhov tseem ceeb, vim tias lawv yuav tsum tiv taus cov kev kub ntxhov ntawm ib puag ncig hauv av thaum tuav lawv txoj kev ncaj ncees mus ntev. Ib qho kev xaiv nrov tshaj plaws rau cov ntawv thov no yog spirally welded carbon steel yeeb nkab, muaj npe nrov rau nws lub zog thiab kav ntev.
S235 JR kauv steel yeeb nkab thiab X70 SSAW (Spiral Submerged Arc Welded) kab yeeb nkab yog ob yam khoom siv dav siv hauv cov kav dej hauv av. S235 JR yeeb nkab tau txais txiaj ntsig zoo rau nws cov khoom siv zoo heev, ua rau nws tsim nyog rau ntau yam kev siv, suav nrog kev thauj mus los hauv dej. Nws lub peev xwm los tiv thaiv deformation nyob rau hauv kev ntxhov siab ua kom nws ua tau raws li qhov xav tau ntawm cov chaw hauv av.
Niaj hnub no, nrog rau cov txheej txheem ceev nrooj hauv nroog, kev txhim khu kev xa dej hauv av tau dhau los ua tus yuam sij los ua kom tib neeg txoj sia nyob. Raws li lub tuam txhab ua lag luam hauv kev lag luam steel yeeb nkab, qee yam steel cog hauv Cangzhou City, Hebei Xeev, tau muab cov kav hlau zoo Saw Welded kav rau ntiaj teb no infrastructure txij li thaum nws tsim nyob rau hauv 1993. Nws S235 JR kauv steel kav thiab X70 submerged arc welded kauv kav, nrog rau lawv zoo heev mechanical zog, tau los ua cov dej num hauv av.
1. Lub zog siab thiab corrosion kuj ua kom muaj kev nyab xeeb ntawm kev xa dej mus sij hawm ntev. S235 JR kauv yeeb nkab: Nws nta zoo heev tiv thaiv kev nyuaj siab deformation thiab yog haum rau complex geological ib puag ncig, kom ntseeg tau lub sij hawm ntev kev ruaj ntseg ntawm cov kav dej. X70 SSAW yeeb nkab: Ua los ntawm cov hlau muaj zog thiab qib siab kauv vuam thev naus laus zis, nws yog lub zog-resistant thiab corrosion-resistant, haum rau kev sib kis dej mus ntev thiab ib puag ncig hnyav.
2. Cov thev naus laus zis siab ua ke nrog kev tswj xyuas nruj tsim kom muaj kev ruaj ntseg kav dej. Lub Hoobkas no tau txais cov khoom siv spiral submerged arc welding (SAW) kom ua tiav cov khoom loj-ntev, nyias-walled raj, optimizing cov khoom siv thaum ua kom muaj zog. Nyob rau hauv kev koom tes nrog ib pab neeg ua hauj lwm ntawm 680 tus neeg thiab ib tug niaj hnub ntau lawm kab tsim nyog 680 lab yuan, peb xyuas kom meej tias txhua txhua steel yeeb nkab ua tau raws li thoob ntiaj teb cov qauv, pab rau kev loj hlob ntawm ntsuab infrastructure. Nrog kev hloov kho tshiab ntawm kev tswj hwm dej thoob ntiaj teb xav tau, cov kav dej saw-welded ntawm Cangzhou Steel Plant yuav txuas ntxiv muab cov kev daws teeb meem siab thiab tsis tshua muaj nqi rau kev thauj mus los hauv nroog, kev ua liaj ua teb thiab kev lag luam dej, txhawb kev tsim kho cov dej txuag dej kom ruaj khov.
cov kav dej sawn-thiab-welded tsim los ntawm Cangzhou Steel Mills yog ib qho tseem ceeb ntawm cov dej hauv av. S235 JR thiab X70 muab kauv submerged arc welded kav, nrog rau lawv cov khoom zoo heev thiab ua haujlwm rau ib puag ncig, yog qhov tseem ceeb rau kev ua kom muaj kev thauj mus los zoo. Saib tom ntej, qhov tseem ceeb ntawm cov khoom no yuav loj hlob ntxiv, qhia txog kev lag luam steel yeeb nkab xav tau kev tsim khoom zoo thiab cov kev daws teeb meem tshiab.
