Taw qhia rau ABS / DH40 Marine Steel PhajTxhais thiab Classification

ABS (American Bureau of Shipping) - DH40 yog lub siab-lub zog marine steel phaj. Lub "DH40" qhia nws qib, nrog "D" feem ntau sawv cev rau cov khoom tshwj xeeb uas muaj feem xyuam nrog kev tsim nkoj thiab "H40" qhia txog nws cov yam ntxwv siab zog. Qhov "40" feem ntau yog hais txog qhov tsawg kawg nkaus cov txiaj ntsig muaj zog (hauv kgf / mm² lossis lwm yam sib npaug). Nyob rau hauv cov ntaub ntawv no, nws implies ib tug kuj siab lub zog haum rau kev thov marine daim ntaub ntawv.

General PropertiesMechanical Properties

Lub zog: Nws muaj lub zog ua haujlwm siab, feem ntau nyob ib puag ncig 390 MPa lossis ntau dua. Lub zog tensile kuj tseem ceeb, feem ntau yog nyob rau hauv ntau yam uas tuaj yeem tiv taus cov khoom hnyav thiab kev ntxhov siab hauv cov dej hiav txwv xws li hydrostatic siab ntawm seawater, qhov hnyav ntawm lub nkoj cov qauv thiab cov khoom thauj, thiab cov dynamic rog ntawm nthwv dej thiab nkoj txav.

Toughness: Lub phaj steel nthuav tawm zoo toughness los tiv thaiv kev cuam tshuam thiab kev thauj khoom sai. Qhov no yog qhov tseem ceeb vim tias cov nkoj tau raug cuam tshuam los ntawm nthwv dej, kev sib tsoo nrog cov khib nyiab ntab, thiab lwm yam kev npaj txhij txog. Lub toughness yog ntsuas los ntawm kev ntsuam xyuas zoo li Charpy V - qhov ntsuas qhov cuam tshuam los xyuas kom meej tias nws tuaj yeem tiv taus cov xwm txheej no yam tsis muaj pob txha tawg.

 

Kev tsim khoomMelting thiab Refining

Kev tsim khoom ntawm ABS / DH40 marine steel phaj pib nrog melting ntawm raw cov ntaub ntawv nyob rau hauv lub cub tawg. Hluav taws xob arc furnaces (EAF) lossis cov pa oxygen yooj yim (BOF) feem ntau yog siv. Cov khoom siv raw, suav nrog cov hlau ore, cov hlau seem, thiab cov hlau alloying, tau ua tib zoo xaiv thiab yaj ua ke. Thaum lub sij hawm melting txheej txheem, qhov kub thiab muaj pes tsawg leeg raug saib xyuas thiab kho kom ntseeg tau tias cov tshuaj muaj pes tsawg leeg xav tau.

Casting thiab Rolling

Tom qab melting thiab refining, cov hlau molten yog cam khwb cia rau hauv semi-tiav khoom xws li slabs los yog billets. Cov no yog tom qab ntawd rov ua dua thiab dhau los ntawm cov txheej txheem dov mills. Cov txheej txheem dov txo cov thickness thiab ua cov hlau rau hauv daim hlau. Qhov ntsuas kub thiab qhov txo qis thaum lub sij hawm dov yog ua tib zoo tswj kom ua tiav cov khoom siv kho tshuab uas xav tau thiab nplua - grained microstructure.

Cov ntawv thov hauv Marine IndustryShipbuilding

Hull Kev Tsim Kho: Nws yog dav siv nyob rau hauv kev tsim cov nkoj hulls, tshwj xeeb tshaj yog rau cov nkoj loj xws li thawv nkoj, cov nqa khoom loj, thiab cov roj tankers. Lub zog siab ntawm DH40 steel phaj ua rau lub nkoj kom tiv taus cov khoom hnyav thiab hnyav marine tej yam kev mob. Cov phaj hauv qab tuaj yeem dais lub siab hydrostatic thiab qhov hnyav ntawm cov khoom thauj, thaum cov phaj sab tuaj yeem tiv taus qhov cuam tshuam yoj thiab tuaj yeem sib tsoo.

Superstructure thiab Internal Compartments: Nyob rau hauv lub nkoj superstructure, nrog rau cabins, txuas hniav, thiab lwm yam chaw, ABS / DH40 steel phaj muab ib tug muaj zog thiab ruaj khov qauv. Nws kuj yog siv nyob rau hauv kev tsim kho ntawm internal compartments xws li bulkheads. Cov bulkheads yuav tsum muaj lub zog txaus los cais cov khoom sib txawv thiab tiv taus qhov sib txawv ntawm qhov sib txawv thiab muaj peev xwm muaj zog thaum muaj xwm txheej.
