Tsis ntev los no, cov xov xwm hais tias kuv lub teb chaws thib peb lub dav hlau thauj khoom, lub nkoj Fujian, tau raug tso tawm, ib zaug ntxiv txhawb txhua lub paj hlwb ntawm cov neeg Suav. Txawm li cas los xij, nyob rau hauv cov txheej txheem tsim khoom ntawm lub dav hlau thauj khoom, ib qho ntawm cov txheej txheem tsis meej tshaj plaws yuav muaj txiaj ntsig zoo kawg nkaus rau kev ua tau zoo thiab kev nyab xeeb. Koj xav li cas yog tus txheej txheem? Qhov ntawd yog vuam.
Hauv kev tsim cov txheej txheem ntawm cov neeg nqa dav hlau, qhov zoo ntawm cov welds tsis yog qhov tseem ceeb rau cov neeg nqa dav hlau xwb, tab sis kuj yog qhov tseem ceeb tshaj plaws nyob rau hauv ntau yam lag luam xws li nuclear fais fab nroj tsuag, siab hlab ntsha, shipbuilding, thiab high-speed rail. Vim yog qhov me me vuam tsis xws luag, tej zaum yuav yog Lub hauv paus ntawm kev ruaj ntseg txaus ntshai, lub embankment ntawm ib txhiab mais, pib nrog cov ntsaum zes. Yog li ntawd, nws yog conceivable yuav ua li cas tseem ceeb qhov zoo ntawm weld yog.
Yog li, 50 hli tuab dav dav dav dav dav dav li cas kom nws cov vuam zoo?
Ua ntej tshaj plaws, cia peb nkag siab txog yam khoom siv lub lawj ntawm lub dav hlau thauj khoom yog dab tsi. Aircraft carrier decks feem ntau siv high-strength alloy steel daim hlau nrog ib tug yield zog ntawm tshaj 400 MPa thiab ib tug tuab ntawm 30 thiab 50 hli. Tam sim no, HY series ntawm Tebchaws Meskas thiab AK series ntawm Russia yog qhov zoo tshaj plaws. Lwm cov tuam txhab steel hauv kuv lub teb chaws kuj tau ua tiav hauv daim teb no, thiab tau siv cov hlau hauv tsev hauv kev tsim kho cov tsheb thauj khoom hauv tsev. Tam sim no, aircraft carrier lawj steel feem ntau dov los ntawm cov dov loj mills. kuv lub teb chaws muaj lub ntiaj teb loj tshaj 5.5-meter dav dav dav phaj dov zeb.
Txij li lub lawj cheeb tsam ntawm lub dav hlau thauj khoom feem ntau ncav cuag ntau dua 15, 000 square meters, cov hlau phaj yuav tsum tau welded ua ke. Yog li, cov txheej txheem vuam twg siv rau vuam ntawm lub lawj no?
Peb txhua tus paub tias qhov tseeb, ntau yam txheej txheem vuam zoo sib xws, tab sis qhov peb xav tau yog kev ua haujlwm siab thiab zoo vuam. Yog li ntawd, ntawm tag nrho cov arc vuam txoj kev siv rau aircraft carrier decks (zoo ib yam li HSLA-100 steel), GTAW (tungsten electrode Inert gas shielded welding) muaj tsawg kawg nkaus inclusions nyob rau hauv lub vuam, tab sis cov txheej txheem vuam no muaj tsawg efficiency thiab yog. zoo dua rau nyias phaj vuam. Yog li ntawd, txhawm rau tiv thaiv lawj steel nrog lub thickness ntawm ntau tshaj 30 hli, BGTAW (submerged arc gas tungsten arc vuam) tuaj yeem siv. , Cov txheej txheem no tsis tas yuav grooves thaum vuam tuab daim hlau, thiab tag nrho cov cua sov nkag yog me dua li ntawm cov txheej txheem vuam zoo tib yam, yog li qhov ua tau zoo ntawm vuam aircraft carrier decks yog siab heev, tab sis nyob rau hauv txhua rooj plaub, nruj vuam txheej txheem specifications yuav tsum tau formulated. los tswj cov kev sib txuas ntawm vuam. Txhawm rau kom ntseeg tau tias qhov tawg tsis kam thiab cov khoom siv kho tshuab ntawm cov vuam, NG-SAW nqaim qhov sib txawv submerged arc vuam tuaj yeem raug xaiv rau cov txheej txheem vuam zoo sib xws.
Tsis tas li ntawd, raws li peb txhua tus paub, vuam yuav ua rau deformation, thiab yuav ua li cas kom lub lawj flatness ntawm qhov loj ntawm lub lawj vuam yog tsawg dua peb txhiab, qhov no yog ib qho tseem ceeb technology, thiab tsis muaj cov ntaub ntawv tseem ceeb tau pom, nws yuav tsum. khaws cia tsis pub leej twg paub. Raws li kev tswj cov kev tswj ntawm vuam deformation muaj kev txhawj xeeb, cov kws tshaj lij vuam tuaj yeem txheeb xyuas yuav ua li cas tswj nws, yog li kuv yuav tsis mus rau hauv cov ntsiab lus ntawm no.
