Txhim kho efficiency thiab zoo yog qhov tseem ceeb nyob rau hauv puas-evolving hnyav manufacturing kev lag luam. Ib qho kev nce qib tseem ceeb tshaj plaws hauv kev siv vuam tshuab tau tshwm sim nyob rau xyoo tas los no yog ob chav submerged arc vuam (DSAW). Lub tshuab tshiab no tsis yog tsuas yog txhim kho cov txheej txheem kev ncaj ncees ntawm cov khoom siv welded, tab sis kuj ua rau cov txheej txheem tsim khoom yooj yim, ua rau nws hloov pauv rau kev lag luam uas vam khom cov khoom hnyav.
Hauv plawv ntawm DSAW yog nws lub peev xwm los tsim cov welds zoo nrog qhov tsis xws luag. Txoj kev koom nrog ob lub arcs uas tau faus rau hauv qab ib txheej ntawm granular flux, uas tiv thaiv lub pas dej weld los ntawm kev sib kis thiab oxidation. Qhov tshwm sim yog ib qho huv si, muaj zog weld uas tuaj yeem tiv taus qhov nruj ntawm kev siv cov khoom siv hnyav. Qhov no tseem ceeb tshwj xeeb rau cov tuam txhab tsim khoomtxias tsim welded qauvhollow seem, xws li cov teev nyob rau hauv European qauv nyob rau hauv round, square los yog rectangular duab. Cov ntu no yog qhov tseem ceeb hauv ntau yam kev siv, suav nrog kev tsim kho, kev tsim kho vaj tse thiab cov tshuab hnyav.
Nyob rau hauv Cangzhou, Hebei Xeev, cov nroj tsuag ua kom pom qhov zoo ntawm DSAW hauv kev tsim khoom hnyav. Founded hauv 1993, cov nroj tsuag npog thaj tsam ntawm 350,000 square meters thiab muaj tag nrho cov cuab tam ntawm 680 lab yuan. Nrog rau 680 tus neeg ua haujlwm mob siab rau, cov nroj tsuag yog tus thawj coj hauv kev tsim cov txheej txheem hollow seem. Los ntawm kev koom ua ke DSAW rau hauv cov txheej txheem tsim khoom, cov nroj tsuag tau txhim kho kev ua tau zoo thiab cov khoom zoo.
Ib qho txiaj ntsig tseem ceeb ntawm DSAW yog kev ceev. Cov txheej txheem tso cai rau kev vuam nrawm dua li cov txheej txheem ib txwm siv, uas txo lub sijhawm ntau lawm. Qhov kev ua tau zoo no yog qhov tseem ceeb rau kev tsim khoom hnyav uas lub sijhawm feem ntau yog qhov tseem ceeb. Los ntawm kev txo lub sijhawm vuam, cov tuam txhab tsim khoom tuaj yeem nce ntau lawm thiab ua tau raws li qhov xav tau ntawm kev sib tw ua lag luam.
Tsis tas li ntawd, DSAW weld zoo nyob twj ywm siab. Cov txheej txheem submerged arc txo qhov kev pheej hmoo ntawm qhov tsis xws luag xws li porosity thiab suav nrog uas tuaj yeem cuam tshuam cov qauv kev ncaj ncees ntawm cov khoom kawg. Qhov no yog ib qho tseem ceeb tshwj xeeb tshaj yog rau qhov txias-tsim welded structural hollow seem, uas yuav tsum tau ua raws li cov qauv nruj nruj kom ntseeg tau tias muaj kev nyab xeeb thiab kev ntseeg siab ntawm lawv cov ntawv thov. Cangzhou cog siv cov thev naus laus zis no los xyuas kom meej tias nws cov khoom tsis yog tsuas yog ua tau raws li cov qauv kev lag luam, tab sis tshaj lawv.
Ntxiv rau kev txhim kho kev ua tau zoo thiab kev ua tau zoo, DSAW kuj pab txuag nqi. Nrog tsawg dua qhov tsis xws luag, tsis tas yuav tsum tau ua dua tshiab, uas txhais tau tias cov tuam txhab tuaj yeem faib cov peev txheej tau zoo dua. Qhov no tshwj xeeb tshaj yog muaj txiaj ntsig zoo rau kev tsim khoom loj, qhov twg cov nqi khoom siv thiab kev ua haujlwm yog qhov tseem ceeb hauv kev tsim khoom tag nrho.
Raws li kev lag luam hnyav kev lag luam txuas ntxiv mus ntxiv, kev siv cov thev naus laus zis thev naus laus zis xws liob submerged arc weldedyuav ua lub luag haujlwm tseem ceeb hauv kev tsim lub neej yav tom ntej. Cov tuam txhab uas nqis peev hauv cov thev naus laus zis no yuav tsis tsuas yog txhim kho kev ua haujlwm zoo tab sis kuj txhim kho cov khoom lag luam zoo, yog li tau txais txoj haujlwm tseem ceeb hauv kev lag luam sib tw.
Nyob rau hauv luv luv, ob chav submerged arc vuam yog revolutionizing hnyav manufacturing los ntawm kev txhim kho efficiency thiab zoo. Cov nroj tsuag no hauv Cangzhou City yog ib qho piv txwv tseem ceeb ntawm yuav ua li cas cov thev naus laus zis tuaj yeem ua haujlwm zoo rau hauv cov txheej txheem tsim khoom, ua kom muaj cov qauv zoo ntawm cov hollow seem uas ua tau raws li cov kev xav tau ntawm kev lag luam niaj hnub no. Raws li cov neeg tsim khoom siv zog rau kev ua tau zoo, kev siv cov thev naus laus zis tshiab xws li DSAW yuav yog qhov tseem ceeb rau kev vam meej hauv xyoo tom ntej.
