Hauv kev tsim cov kav dej roj av, kev xaiv cov khoom siv thiab cov txheej txheem vuam yog qhov tseem ceeb rau kev ua kom muaj kev nyab xeeb thiab kev ua haujlwm zoo. SSAW (Spiral Submerged Arc Welded) cov kav hlau yog ib qho ntawm cov ntaub ntawv siv ntau tshaj plaws hauv kev lag luam no. Hauv tsab ntawv blog no, peb yuav tshawb nrhiav qhov tseem ceeb ntawm cov txheej txheem vuam kom zoo rau kev teeb tsa cov kav dej roj av siv cov kav hlau SSAW thiab muab cov lus qhia yooj yim rau kev nkag siab txog qhov tseem ceeb no ntawm kev tsim cov kav dej.
SSAW Yeeb Nkab Hlau yog dab tsi?
SSAW yeeb nkab hlauyog ua los ntawm cov hlau uas tau vuam ua ke los tsim cov yeeb nkab loj uas muaj zog thiab ruaj khov. Hom yeeb nkab no nrov heev hauv kev lag luam roj thiab roj vim nws tiv taus kev kub siab thiab xeb. Nws cov txheej txheem tsim khoom siv kev vuam submerged arc, uas tsim cov vuam huv thiab muaj zog, ua rau nws zoo tagnrho rau cov ntawv thov tseem ceeb xws li cov kav dej roj av.
Qhov Tseem Ceeb ntawm Cov Txheej Txheem Vuam Kom Zoo
Kev vuam yog ib kauj ruam tseem ceeb hauv cov txheej txheem teeb tsa cov kav dej roj av, thiab qhov zoo ntawm qhov vuam tuaj yeem cuam tshuam rau qhov kev ncaj ncees ntawm cov kav dej. Cov txheej txheem vuam kom zoo yog qhov tseem ceeb kom ntseeg tau tias cov yeeb nkab hlau SSAW muaj zog thiab tsis xau. Nov yog qee yam tseem ceeb uas yuav tsum xav txog thaum vuam cov yeeb nkab hlau SSAW rau cov kav dej roj av:
1. Kev Siv Vuam: Kev xaiv cov txheej txheem vuam cuam tshuam rau qhov zoo ntawm qhov vuam. Nyob ntawm qhov xav tau tshwj xeeb ntawm qhov project, cov txheej txheem xws li TIG (Tungsten Inert Gas) lossis MIG (Metal Inert Gas) tuaj yeem siv tau. Txhua txoj kev muaj nws qhov zoo thiab qhov tsis zoo, thiab kev xaiv cov txheej txheem zoo yog qhov tseem ceeb kom ua tiav kev sib txuas zoo.
2. Kev Npaj Khoom Siv: Ua ntej vuam, yuav tsum npaj qhov chaw ntawm cov yeeb nkab hlau uas muaj kauv uas tau muab tso rau hauv qab dej. Qhov no suav nrog kev ntxuav qhov chaw thiab tshem tawm cov khoom tsis huv uas yuav ua rau qhov vuam tsis muaj zog, xws li xeb, roj lossis av qias neeg. Tsis tas li ntawd, cov yeeb nkab yuav tsum tau teeb tsa kom zoo kom ntseeg tau tias qhov vuam sib npaug.
3. Cov kev ntsuas vuam: Cov yam xws li kev vuam ceev, qhov hluav taws xob thiab tam sim no yuav tsum tau tswj hwm kom zoo thaum lub sijhawmyeeb nkab hlau rau vuamCov kev ntsuas no cuam tshuam rau qhov cua sov nkag thiab qhov txias, uas ua rau muaj kev cuam tshuam rau cov khoom siv kho tshuab ntawm qhov vuam.
4. Kev Tshuaj Xyuas Tom Qab Vuam: Tom qab vuam, yuav tsum tau ua kev tshuaj xyuas kom meej kom pom qhov tsis zoo lossis qhov txuas tsis muaj zog hauv qhov vuam. Cov txheej txheem kuaj tsis ua puas tsuaj xws li kev kuaj ultrasonic lossis kev kuaj radiographic tuaj yeem siv los xyuas kom meej tias qhov vuam ruaj khov.
Peb Txoj Kev Cog Lus Rau Qhov Zoo
Nyob hauv Cangzhou, Hebei Xeev, lub tuam txhab tau ua tus thawj coj hauv kev lag luam tsim cov yeeb nkab hlau txij li xyoo 1993. Lub tuam txhab npog thaj tsam ntawm 350,000 square meters, muaj tag nrho cov cuab tam ntawm RMB 680 lab, thiab muaj 680 tus kws tshaj lij mob siab rau kev tsim cov yeeb nkab hlau zoo. Peb cov kev paub nplua nuj thiab cov khoom siv siab heev ua rau peb ua tau raws li cov kev cai nruj ntawm kev lag luam roj av.
