Arc vuam yog cov txheej txheem siv dav hauv kev tsim cov kav dej, tshwj xeeb tshaj yog rau cov ntawv thov uas muaj cov khoom siv hauv av. Txawm li cas los xij, zoo li txhua txoj kev lag luam, nws los nrog nws tus kheej cov teeb meem nyuaj. Hauv qhov blog no, peb yuav tshawb nrhiav cov kev cov nyom uas tau ntsib thaum lub sij hawm lub raj xa hluav taws xob arc vuam thiab muab cov kev daws teeb meem zoo los xyuas kom meej cov khoom zoo, ruaj khov.
Peb lub Hoobkas nyob hauv Cangzhou, Hebei Xeev thiab tau nyob rau hauv pem hauv ntej ntawm kev tsim yeeb nkab txij li xyoo 1993. Peb lub Hoobkas npog thaj tsam ntawm 350,000 square meters thiab muaj 680 tus neeg ua haujlwm tshaj lij. Peb txaus siab los siv cov txheej txheem spiral submerged arc vuam thev naus laus zis, uas ua kom muaj txiaj ntsig zoo thiab ua haujlwm ntev ntawm peb cov khoom. Lub tshuab thev naus laus zis niaj hnub no yog tsim los ua kom tau raws li cov qauv siab tshaj plaws ntawm cov dej hauv av, ua rau peb cov kav dej muaj kev ntseeg siab thiab siv tau ntev rau ntau yam kev siv.
Common Challenges ntawm ArcWelded yeeb nkab
1. Tsis zoo weld zoo: Ib qho ntawm cov teeb meem tshwm sim hauv arc vuam yog ua tiav qhov zoo sib xws. Kev hloov pauv hauv cov khoom siv hluav taws xob, kev mus ncig ceev, thiab lub kaum sab xis electrode tuaj yeem ua rau lub vuam tsis muaj zog lossis tsis tiav.
Kev daws: Siv cov kev tswj xyuas nruj nruj thiab siv cov tshuab vuam tshuab tuaj yeem pab tswj tau qhov sib xws. Kev cob qhia tsis tu ncua ntawm welders ntawm kev coj ua zoo tshaj plaws thiab siv cov cuab yeej saib xyuas qib siab tuaj yeem txhim kho qhov zoo ntawm vuam.
2. Deformation thiab dabtsi yog khoov: Lub tshav kub tsim thaum lub sij hawm vuam yuav ua rau cov yeeb nkab khoov los yog deform, uas ua rau misalignment thiab tej zaum tsis ua hauj lwm nyob rau hauv daim ntawv thov.
Kev daws: Preheating cov yeeb nkab ua ntej vuam thiab siv cov txheej txheem clamping kom zoo tuaj yeem txo qhov cuam tshuam. Tsis tas li ntawd, kev siv cov txheej txheem vuam ntau dhau tuaj yeem pab faib cov cua sov kom sib npaug, txo qhov kev pheej hmoo ntawm kev sib tsoo.
3. Porosity thiab Inclusions: Lub xub ntiag ntawm cov hnab tshos huab cua (porosity) lossis cov khoom txawv teb chaws (suav nrog) hauv cov vuam tuaj yeem cuam tshuam qhov kev ncaj ncees ntawm cov yeeb nkab.
Kev daws: Ua kom lub chaw ua haujlwm huv si thiab siv cov khoom siv ua kom zoo tuaj yeem txo qhov kev pheej hmoo ntawm porosity thiab kev suav nrog. Kev tshuaj xyuas tsis tu ncua ntawm cov khoom siv vuam thiabarc vuam yeeb nkabNws tseem yog ib qho tseem ceeb los tswj kev huv.
4. Kev sib tsoo: Vim yog qhov txias txias los yog cov txheej txheem vuam tsis raug, kev tawg tuaj yeem tshwm sim, ua rau cov txheej txheem tsis ua haujlwm ntawm cov kav dej.
Kev daws: Kev tswj cov cua txias thiab siv cov txheej txheem preheating tuaj yeem pab tiv thaiv kev tawg. Tsis tas li ntawd, xaiv cov khoom muab tub lim kom zoo uas haum rau cov khoom siv niam txiv tuaj yeem txhim kho qhov kev sib txuas ntawm kev sib tsoo.
5. Kev nkag mus tsis txaus: Kev nkag mus tsis txaus tuaj yeem ua rau muaj kev sib koom ua ke tsis muaj zog uas yuav ua tsis tau raws li qhov siab.
Kev daws: Kho qhov vuam tsis xws li qhov hluav taws xob thiab qhov tam sim no tuaj yeem ua rau qhov tob ntawm qhov vuam. Kev tshuaj xyuas kom meej thiab ntsuas qhov vuam yuav pab txheeb xyuas thiab kho txhua yam teeb meem ua ntej lub raj xa dej raug muab tso rau hauv kev pabcuam.
nyob rau hauv xaus
Ntawm peb qhov chaw Cangzhou, peb nkag siab qhov tseem ceeb ntawm kev kov yeej cov kev sib tw arc vuam no los tsim cov yeeb nkab uas ua tau raws li cov qauv siab tshaj plaws ntawm kev ua tau zoo thiab kav ntev. Los ntawm kev siv cov kauv submerged arc vuam tshuab, peb xyuas kom meej tias peb cov khoom tsis yog tsuas yog txhim khu kev qha tab sis kuj muaj peev xwm ua tau raws li qhov xav tau ntawm ntau yam kev siv, tshwj xeeb tshaj yog nyob rau hauv cov dej hauv av.
Los ntawm kev ntsib cov kev cov nyom no mus rau thiab siv cov kev daws teeb meem zoo, peb tuaj yeem txuas ntxiv muab peb cov neeg siv khoom nrog cov khoom zoo uas sawv cev rau lub sijhawm. Txawm hais tias koj xav tau cov kav dej rau kev tsim kho, kev tsim kho vaj tsev lossis kev siv hauv kev lag luam, peb txoj kev cog lus rau kev ua tau zoo thiab kev tsim kho tshiab ua kom koj tau txais cov kev daws teeb meem zoo tshaj plaws rau koj cov kev xav tau.
