Dab tsi yog qib ntawm Steel siv hauv Shipbuilding? Phau Ntawv Qhia Txog Tswv Yim rau Marine Engineers thiab Pab Pawg Muag Khoom
Yog tias koj koom nrog hauv kev tsim nkoj, kho nkoj, lossis kev tsim kho sab nrauv, ib qho ntawm thawj cov lus nug uas koj yuav ntsib yog:Kuv yuav siv steel qib twg?
Cov lus teb tsis yooj yim li "ib qib haum txhua tus." Ntau qhov chaw ntawm lub nkoj ntsib cov kev ntxhov siab sib txawv, qhov kub thiab txias, thiab kev pheej hmoo. Xaiv cov qib hlau tsis raug tuaj yeem ncua kev pom zoo rau kev faib tawm, cuam tshuam kev nyab xeeb, lossis nce nqi.
Lus Teb luv luv: Nws nyob ntawm lub zog & Toughness
Shipbuilding steels poob rau hauv ob pawg loj:
General zog steels(Qib A, B, D, E) - Siv rau tsawg dua - thaj chaw tseem ceeb xws li cov tsev loj loj lossis cov khoom siv sab hauv.
Siab - steels(Qib AH32, DH32, EH32, mus txog FH40 thiab tshaj) - Siv rau lub nkoj, decks, thiab lwm yam thauj khoom-cov kabmob.
Tab sis qhov sib txawv tiag tiag los ntawmob txoj kev ntsuas kev ua haujlwm:
Yield zog(kev ntxhov siab npaum li cas nws tuaj yeem siv ua ntej khoov mus tas li)
Impact toughness(zoo npaum li cas nws tiv thaiv cracking ntawm qis kub)
| Qib | Yam tsawg kawg nkaus yield zog (MPa) | Tej yam tshwm sim ntsuas kub | Cov ntawv thov siv |
|---|---|---|---|
| General zog (A, B, D, E) | 235 | +20℃rau -40 degree | Superstructure, lub teeb bulkheads |
| Siab - zog 32 (AH32, DH32, EH32) | 315 | 0℃rau -40 degree | Hull plhaub, sab hauv qab |
| Siab - zog 36 (AH36, DH36, EH36) | 355 | 0℃rau -40 degree | Hnyav- chaw thau khoom, decks, longitudinal girders |
| Siab -lub zog 40 (AH40–FH40) | 390 | 0℃rau -40 degree | Cov chaw muaj kev ntxhov siab heev hauv cov nkoj loj |
Yog vim li cas "D36" yog ib qho ntawm cov Nrov Nrov Nkoj Tsim Qib Qib
Ntawm - lub zog steels,D36(thiab nws cov txheeb ze zeEH 36) yog neeg ua haujlwm. Noj covD36 shipbuilding steel phajua ib qho piv txwv:
Yield zog Ntau tshaj los yog sib npaug rau 355 MPa- kwv yees li 42% muaj zog dua li dav dav - zog Qib A.
Impact kuaj ntawm -20 degree- pov thawj toughness rau dej hiav txwv txias (North Hiav txwv, Baltic, Arctic txoj kev).
Carbon sib npaug (CEV) Tsawg dua lossis sib npaug li 0.38%- weldability zoo heev, txhais tau tias tsawg dua preheating los yog tom qab -weld cua sov cov kauj ruam.
Pom zoo los ntawm ABS, DNV, LR, BV, CCS, NK, KR, RINA– tsis muaj re- ntawv pov thawj qeeb thaum tsim rau cov kev cai sib txawv.

Yuav Ua Li Cas Xaiv Cov Qib Zoo rau Koj Qhov Haujlwm
Dab tsi yog qhov kub qis tshaj plaws uas cov hlau yuav ntsib hauv kev pabcuam?
Tshaj 0℃→ Qib A lossis AH32 tuaj yeem txaus.
Nqes mus rau -20℃→ Qib D lossis DH36 (zoo li D36) muaj kev nyab xeeb dua.
Nqes mus rau -40℃lossis qis dua → Qib E lossis EH36 / FH36 xav tau.
Cov qauv kev nyuab siab npaum li cas?
Kev ntxhov siab tsawg (piv txwv li, sab hauv bulkheads) → General zog (235 MPa).
Kev ntxhov siab siab (piv txwv li, lub hauv qab lub cev, lub cev ntaj ntsug) → Siab -lub zog 32 lossis 36 (315–355 MPa).
Kev ntxhov siab heev (piv txwv li, lub thawv nkoj hatch ces kaum) → Qib 40 (390 MPa) lossis siab dua.
Lub koom haum cais twg yuav pom zoo rau lub nkoj?
Txhua lub koom haum loj lees txais qib A, B, D, E thiab AH–FH, tab sisnco ntsoov xyuas cov ntawv qhia qib tshwj xeebnyob rau hauv phau ntawv txoj cai. Piv txwv li, qee lub zej zog xav tau EH36 rau dej khov- thaj chaw muaj zog, tsis yog DH36.
vim li cas ho xaiv peb?
Peb cog lus tias yuav muab cov ntaub ntawv pov thawj ntawm lub Hoobkas muaj tseeb thiab pov thawj los ntawm Lub Koom Haum Classification Society thiab cov ntawv pov thawj tshuaj xyuas cov khoom nrog rau cov khoom. Qhov no yog ib qho tseem ceeb heev uas yuav tsum tau rau lub shipyard warehouse txais txheej txheem.
Cov kev qhia tshwj xeeb (6-40mm) yog nyob rau hauv cov khoom txaus thiab tuaj yeem txiav mus rau qhov ntev raws li cov neeg siv khoom xav tau. Qhov tshwj xeeb no pab cov chaw nres nkoj txo cov khoom pov tseg los ntawm cov khoom seem thiab txo cov nqi yuav khoom.
Raws li qhov loj ntawm qhov kev txiav txim thiab keeb kwm ntawm kev koom tes, peb tuaj yeem muab cov nqe lus them nqi sib tw los pab lub nkoj ua kom zoo dua nws cov nyiaj ntsuab.

FAQ
01.Kuv puas tuaj yeem siv D36 steel rau txhua qhov chaw ntawm lub nkoj?
02.Dab tsi yog qhov txawv ntawm DH36 thiab D36?
Hauv kev xyaum, lawv xa mus rau tib lub hlau. "D36" yog lub npe nrov hauv cov qauv xws li ASTM A131, thaum "DH36" feem ntau siv rau hauv kev faib cov cai hauv zej zog (xws li DNV, ABS). Ob leeg qhia tias:
Yam tsawg kawg yield zog: 355 MPa
Kev ntsuas kub: -20 degree
Kev pom zoo rau kev tsim nkoj thiab kev siv sab nrauv
03. Kuv yuav ua li cas thiaj paub tseeb tias lub phaj D36 muaj ntawv pov thawj tiag?
Ib txwm thovDaim ntawv pov thawj zeb (EN 10204 Hom 3.2)uas suav nrog:
Thaum tshav kub kub tooj traceable rau steel phaj
Mechanical test results (yield, tensile, impact)
