Mechanical Properties

 

Yield Strength thiab Tensile Strength: Lub hull qauv ntawm cov khoom thauj khoom loj yuav tsum tiv taus qhov siab loj. Yog li ntawd, lub zog tawm los thiab tensile lub zog ntawm high-lub zog steel daim hlau (xws li AH32 thiab AH36) yuav tsum ua raws li cov qauv nruj. Piv txwv li, lub zog tawm los ntawm AH32 steel phaj tsis tsawg dua 315 MPa, thiab lub zog tensile nyob nruab nrab ntawm 440 - 570 MPa; lub zog tawm los ntawm AH36 steel phaj tsis tsawg dua 355 MPa, thiab lub zog tensile nyob nruab nrab ntawm 490 - 621 MPa. Cov ntsuas lub zog no tuaj yeem ua kom ntseeg tau tias cov phaj hlau yuav tsis yooj yim rau cov yas deformation lossis tawg thaum nws dais ntau yam khoom xws li qhov hnyav ntawm cov khoom thauj loj hauv cov khoom thauj khoom thauj khoom thauj khoom, qhov siab ntawm seawater thaum navigation, thiab cuam ​​tshuam lub zog thaum thauj khoom thiab tshem tawm cov khoom thauj.

 

Elongation: Tus elongation tus nqi kuj yog ib qho tseem ceeb qhia. Rau siab-lub zog steel daim hlau siv nyob rau hauv tej nqa khoom, tus nqi elongation feem ntau yuav tsum tsis pub tsawg tshaj 22%. Tus nqi elongation ntau dua txhais tau hais tias cov phaj hlau tuaj yeem tsim tau qee yam ntawm cov yas deformation yam tsis muaj kev tawg thaum raug lub zog tensile. Qhov no yog qhov tseem ceeb heev thaum lub nkoj ntsib qhov kev npaj txhij txog muaj zog sab nraud (xws li kev sib tsoo thiab hauv av). Los ntawm qhov tsim nyog elongation deformation, cov phaj hlau tuaj yeem nqus tau lub zog thiab txo cov kev ntxhov siab, yog li tiv thaiv tag nrho kev ncaj ncees ntawm cov qauv hull.

 

 

 

Dimensional Accuracy thiab Surface Quality

 

Dimensional raug: Qhov tseeb qhov tseeb ntawm qhov tuab, qhov ntev, thiab qhov dav ntawm cov phaj steel yog qhov tseem ceeb rau kev tsim cov khoom thauj khoom loj. Nyob rau hauv kev tsim kho ntawm lub nkoj, cov hlau daim hlau nyob rau hauv ntau qhov chaw xav tau qhov ntev kom paub tseeb tias qhov tseeb ntawm kev sib dhos. Piv txwv li, yog hais tias lub thickness sib txawv ntawm lub hauv qab steel phaj loj heev, nws yuav cuam tshuam rau tag nrho lub zog thiab stability ntawm lub hull. Feem ntau hais lus, lub thickness kam rau ua ntawm steel phaj yuav tsum tau tswj nyob rau hauv ib tug nqaim ntau yam, thiab qhov sib txawv ntawm qhov ntev thiab qhov dav kuj yuav tsum tau ua raws li cov qauv tsim.

 

Nto Zoo: Qhov saum npoo ntawm cov hlau phaj yuav tsum tiaj tus thiab du yam tsis muaj qhov tsis xws luag xws li tawg, sib xyaw, thiab delamination. Cov phaj hlau uas tsis zoo ntawm qhov chaw yuav dhau los ua kev ntxhov siab - cov ntsiab lus concentration thaum siv, yog li ua rau tiam thiab nthuav tawm ntawm cov kab nrib pleb. Tshwj xeeb tshaj yog nyob rau hauv lub cargo tuav cheeb tsam ntawm ib tug bulk carrier, yog hais tias muaj tsis xws luag nyob rau hauv lub nto ntawm lub steel phaj, nws yog feem ntau yuav puas thaum coj lub siab thiab kev sib txhuam ntawm cov khoom thauj, cuam tshuam rau lub neej kev pab cuam thiab kev ruaj ntseg ntawm lub nkoj. Nyob rau tib lub sijhawm, qhov zoo ntawm qhov chaw zoo kuj tseem muaj txiaj ntsig zoo rau cov txheej txheem tom ntej ntawm kev kho deg xws li pleev xim, txhim kho kev ua haujlwm ntawm cov hlau phaj.

Vuam Performance

 

Weldability zoo: Cov txheej txheem vuam ntau yog siv rau hauv cov txheej txheem kev tsim kho ntawm cov cab kuj. Yog li ntawd, high-lub zog steel daim hlau yuav tsum muaj zoo weldability. Qhov no yuav tsum tau hais tias thaum lub sij hawm vuam txheej txheem, cov vuam hlau thiab lub hauv paus hlau tuaj yeem ua tau zoo - fused yam tsis muaj kev sib tsoo vuam, qhov pores, thiab lwm yam tsis xws luag. Zoo weldability yog ze ze rau cov tshuaj muaj pes tsawg leeg ntawm steel phaj. Raws li tau hais los saum no, kev tswj hwm cov ntsiab lus xws li carbon, phosphorus, thiab sulfur, nrog rau qhov tsim nyog ntawm cov ntsiab lus alloying, yog txhua yam los xyuas kom meej tias cov welds zoo tuaj yeem tau txais thaum lub sij hawm vuam ntawm cov hlau phaj.

 

Txhim kho cov cuab yeej cuab tam tom qab Vuam: Cov khoom siv hluav taws xob ntawm cov welded steel phaj nyob rau hauv lub vuam thiab cov cua sov - cuam tshuam cheeb tsam yuav tsum ua tau raws li qhov yuav tsum tau muaj ntawm cov qauv hull. Piv txwv li, lub zog tawm los, lub zog tensile, cuam tshuam toughness, thiab lwm yam kev ntsuas tom qab vuam yuav tsum tsis txhob txo qis vim qhov txheej txheem vuam. Qhov no yuav tsum muaj kev tswj xyuas nruj ntawm kev xaiv cov txheej txheem vuam tsis zoo (xws li vuam tam sim no, qhov hluav taws xob, thiab vuam ceev), thiab nws kuj tseem yuav tsim nyog los txais yuav cov khoom siv vuam tsim nyog thiab tom qab - vuam cua sov - txheej txheem kev kho mob kom ntseeg tau tias cov welded steel phaj. tuaj yeem tswj tau cov khoom siv kho tshuab zoo.
