BV Marine Steel Phaj Qib B

Qhov sib txawv ntawm BV Marine Steel Phaj Qib E, Qib D, thiab Qib B:
Impact toughness test kub thiab kev ua haujlwm:
Qib B: Qhov ntsuas qhov ntsuas kub yog {{0}} degree . Qhov no txhais tau hais tias thaum qhov kev ntsuam xyuas qhov cuam tshuam tau ua tiav ntawm 0 degree, cov hlau yuav tsum muaj peev xwm ncav cuag qhov cuam tshuam qhov toughness index. Piv nrog rau Qib A steel (kev cuam tshuam qhov kub thiab txias yog 20 degree), nws hloov tau mus rau qhov kub thiab txias ib puag ncig zoo dua.
Qib D: Qhov ntsuas qhov ntsuas kub yog -20 degree . Thaum cov qib no ntawm cov hlau no raug rau qhov kev ntsuas cuam tshuam hauv qhov chaw qis qis ntawm qhov kub ntawm 20 degree, nws tseem tuaj yeem tswj tau qhov zoo thiab tsim nyog rau cov nkoj caij nkoj hauv cov huab cua txias lossis cov qauv marine siv nyob rau hauv qhov kub thiab txias.
Qib E: Qhov ntsuas qhov ntsuas kub yog -40 degree . Nws muaj qhov zoo tshaj plaws kub-kub toughness ntawm peb qib no thiab muaj peev xwm tuav tau zoo cuam tshuam nyob rau hauv ib qho chaw txias heev ntawm rho tawm 40 degree. Nws yog ib qho tseem ceeb heev rau kev siv engineering marine nyob rau hauv cov dej hiav txwv txias heev los yog cov uas tsis tshua muaj siab xav tau rau kev ua haujlwm qis.
Qhov sib txawv me ntsis ntawm cov tshuaj muaj pes tsawg leeg: Txawm hais tias peb qib ntawm cov hlau no tag nrho yog cov khoom siv dav dav hauv nkoj tsim steel, tej zaum yuav muaj qee qhov sib txawv ntawm cov tshuaj lom neeg tshwj xeeb. Piv txwv li, tej zaum yuav muaj kev tswj sib txawv rau cov ntsiab lus ntawm qee yam alloying ntsiab lus, thiab qhov sib txawv no yuav cuam tshuam rau kev ua haujlwm ntawm cov hlau. Txawm li cas los xij, feem ntau, lawv cov tshuaj lom neeg tseem ceeb yog hlau, carbon, silicon, manganese, thiab lwm yam, thiab cov ntsiab lus tseem ceeb xws li cov ntsiab lus ntawm cov pa roj carbon monoxide yog khaws cia nyob rau hauv ib qho kev ua kom muaj zog thiab lub zog ntawm cov hlau.
Ua kom pom tseeb ntawm daim ntawv thov scenarios:
Qib B: Tsim nyog rau kev tsim cov nkoj zoo tib yam uas tsis muaj kev xav tau tshwj xeeb rau kev ua haujlwm kub qis, xws li cov qauv hull thiab lawj ntawm cov nkoj me me lossis nruab nrab ntawm kev caij nkoj hauv hiav txwv sov, thiab qee qhov chaw ua haujlwm hauv hiav txwv. uas tsis muaj kev xav tau siab rau kev ua haujlwm qis-kub ntawm steel.
Qib D: Feem ntau siv hauv kev tsim nkoj hauv hiav txwv nrog cov huab cua txias, xws li Hiav Txwv North thiab hiav txwv Baltic. Hauv kev tsim khoom hauv dej hiav txwv, nws kuj tseem tsim nyog rau qee cov qauv uas yuav cuam tshuam los ntawm qhov kub thiab txias, xws li offshore platforms ze rau thaj tsam polar.
 

 

 

 

Qib E: Feem ntau yog siv rau hauv nkoj thiab marine engineering cov qauv ua haujlwm hauv hiav txwv txias heev, xws li cov nkoj hauv thaj chaw txias heev xws li dej hiav txwv Arctic thiab cov roj hauv hiav txwv tob. Cov qauv no xav tau cov hlau kom muaj qhov kub thiab txias zoo heev los xyuas kom muaj kev nyab xeeb thiab kev ntseeg siab hauv qhov chaw hnyav.
Shipbuilding steel qib ntawv pov thawj los ntawm Bureau Veritas:
General-strength steel qib: Muab faib ua plaub qib A, B, D, thiab E. Qhov yuav tsum tau muaj zog tensile, yield zog, thiab elongation yog roughly tib yam, tab sis qhov cuam tshuam toughness ntsuas kub sib txawv. Los ntawm Qib A mus rau Qib E, qhov yuav tsum tau muaj rau qhov kub thiab txias toughness maj mam nce.
High-strength steel qib: Muab faib ua ob theem zog thiab peb qib zoo, tshwj xeeb xws li AH32, DH32, EH32, AH36, DH36, EH36, thiab lwm yam. Cov hlau uas muaj zog muaj zog ntau dua nyob rau hauv cov ntsiab lus ntawm lub zog thiab toughness thiab tsim nyog rau nkoj thiab marine engineering cov qauv nrog cov kev xav tau ntau dua rau kev ua haujlwm steel, xws li cov nkoj loj hauv hiav txwv mus thiab cov ntug dej hiav txwv siab platforms.
