Kauv steel kav yog tsim los ntawm dabtsi yog khoov sawb hlau los yog coils mus rau hauv ib tug kauv puab thiab welding lub puab thiab sab seams siv ob-sided submerged arc vuam. Vim yog cov laj thawj hauv qab no, lawv tau siv dav hauv kev lag luam xws li dej, hluav taws xob, thiab tshuaj lom neeg: Los ntawm kev kho lub kaum sab xis yooj yim, ntau txoj kab uas hla ntawm cov yeeb nkab steel tuaj yeem tsim los ntawm tib qhov dav ntawm sawb hlau, ua kom yooj yim hloov.
Txij li thaum cov tsim yog nruam thiab nkhaus, qhov ntev ntawm kauv kav tsis txwv thiab tuaj yeem kho raws li qhov xav tau. Lub kauv weld seam yog sib npaug sib npaug nyob ib ncig ntawm tag nrho lub voj voog ntawm cov yeeb nkab, uas ua rau muaj qhov tseeb qhov tseeb thiab lub zog. Tsis tas li ntawd, nws yog ib qho yooj yim los kho qhov ntev, ua rau nws haum rau me me-batch, ntau hom kev tsim cov kav kav dej.
Lub weld seam ntawm kauv steel kav yog ntev tshaj li ntawm ncaj seam kav ntawm tib tus qauv. Nyob rau hauv tib lub phab ntsa tuab, kauv steel kav tuaj yeem tiv taus qhov siab tshaj plaws. Txawm li cas los xij, qhov tsis zoo ntawm cov kav hlau kav yog nyob hauv lawv "oblique defects" hauv cov vuam seam. Thaum siv, qhov sib npaug ntawm qhov tsis xws luag ntev nyob rau hauv cov kev taw qhia ntawm lub ntsiab kev nyuaj siab, piv txwv li, lub axis ntawm cov yeeb nkab, yog me dua li ntawm ncaj seam kav. Tsis tas li ntawd, txij li cov yeeb nkab steel feem ntau yog dov daim hlau, muaj anisotropy tseem ceeb hauv kev cuam tshuam toughness. Tus nqi CVN nyob rau hauv qhov kev taw qhia dov tuaj yeem yog peb zaug siab dua li qhov perpendicular mus rau dov kev taw qhia.
Txhawm rau ua kom tau raws li qhov xav tau ntawm kev tsim khoom niaj hnub no, kev cob qhia steel qauv tau tshwm sim. Piv nrog rau cov kev cob qhia thaum ntxov, kev cob qhia steel qauv muaj ntau qhov zoo, nrog rau lub sijhawm luv luv, cov nqi qis dua, thiab kev ua haujlwm tau zoo. Feem ntau, steel qauv rhiav encompass steel kem, steel beams, steel foundations, steel ru tsev trusses, steel ru tsev, thiab lwm yam nyob rau hauv xyoo tas los no, steel kem tau maj hloov los ntawm kev siv channel steel, uas tau pom tias muaj kev txwv nyob rau hauv kev tsim kho, mus rau kauv. cov kav hlau.
Hauv kev cob qhia steel qauv, kauv steel kav muaj ntau yam zoo. Lawv yog cov adaptable heev nyob rau hauv cov nqe lus ntawm cov qauv, tso cai rau zus tau tej cov kav dej ntawm txhua tus qauv. Qhov ntev ntawm kauv steel kav kuj tuaj yeem kho tau, nrog qhov ntev tshaj plaws ncav cuag 30 meters. Tsis tas li ntawd, kauv steel kav tuaj yeem tsim rau hauv cov ncej ua ke, muab kev ua tau zoo dua piv rau cov hlau channel thiab ntawm tus nqi pheej yig dua.
