Taw qhia rau Cov Qib SteelAH32 thiab AH36:

Cov no yog high-lub zog hull structural steels. Lub "A" sawv cev rau cov hlau rau cov qauv hull, thiab "H" qhia tias muaj zog heev. Cov lej "32" thiab "36" yog hais txog qhov tsawg kawg nkaus qhov muaj zog ntawm cov khoom muaj zog (hauv kgf / mm²) ntawm cov hlau. AH32 muaj qhov tsawg kawg nkaus yield zog ntawm 315 MPa (kwv yees 32 kgf / mm²), thiab AH36 muaj qhov tsawg kawg nkaus yield zog ntawm 355 MPa (kwv yees. 36 kgf / mm²). Lawv tau tsim los tiv thaiv cov khoom hnyav thiab kev ntxhov siab uas cov nkoj tau ntsib thaum lub sijhawm ua haujlwm, xws li qhov hnyav ntawm cov khoom thauj, qhov siab ntawm cov dej, thiab lub zog muaj zog los ntawm nthwv dej thiab navigation.

 

CCS A, B, D, E:

CCS sawv cev rau Tuam Tshoj Classification Society. Cov qib A, B, D, thiab E yog qhov sib txawv ntawm kev faib khoom ntawm lub nkoj - lub tsev steels raws li CCS cov qauv. Qib A yog qib pib nrog cov kev xav tau qis dua rau kev cuam tshuam rau kev nyuaj siab, thaum qib B, D, thiab E muaj kev xav tau ntau dua rau kev cuam tshuam, tshwj xeeb tshaj yog nyob rau hauv qis dua. Cov qib no yog siv los ua kom tau raws li qhov xav tau ntawm ntau hom nkoj thiab kev ua haujlwm.

Cov Khoom thiab Lawv Qhov Tseem Ceeb rau Lub Tsev NkojLub zog:

Lub siab - lub zog ntawm AH32, AH36, thiab DH36 tso cai rau kev tsim kho kom zoo dua qub thiab sib dua - qhov hnyav ntawm lub nkoj. Los ntawm kev siv cov hlau no, shipbuilders tuaj yeem txo qhov tuab ntawm daim hlau thaum tseem tuav lub zog tsim nyog. Qhov no tsis tsuas yog txuag cov nqi khoom siv xwb tab sis kuj txo qhov hnyav tag nrho ntawm lub nkoj, ua rau kom muaj roj zoo dua thiab nce cov khoom thauj - nqa lub peev xwm. Piv txwv li, hauv kev tsim kho cov nkoj loj loj lossis cov neeg nqa khoom loj, kev siv AH36 steel rau lub nkoj tuaj yeem txhim kho lub nra hnyav ntawm lub nkoj.

Toughness:

Qhov zoo toughness ntawm cov hlau no, tshwj xeeb tshaj yog qhov tsis tshua muaj kub toughness ntawm DH36, yog qhov tseem ceeb rau kev nyab xeeb ntawm cov nkoj. Cov nkoj tau raug cuam tshuam tas li rau ntau lub zog sab nraud xws li kev cuam tshuam yoj, kev sib tsoo nrog cov khoom ntab, thiab txawm tias cov dej khov nab kuab hauv cheeb tsam polar. Lub zog ntawm cov hlau ua kom nws nqus tau lub zog thaum muaj kev cuam tshuam, tiv thaiv kev tawg sai sai uas tuaj yeem ua rau muaj kev puas tsuaj loj xws li kev ua txhaum ntawm lub cev. Hauv cov cheeb tsam dej txias, lub peev xwm ntawm DH36 los tswj nws qhov hnyav yog qhov tseem ceeb rau kev ncaj ncees ntawm lub nkoj cov qauv.

 

Cov Qauv Txheej Txheem:

Lawv yog siv los tsim ntau yam khoom siv hauv lub nkoj, xws li thav duab, bulkheads, thiab pillars. Cov thav duab muab cov txheej txheem nruj ntawm lub hull, thiab kev siv cov high-lub zog steels tuaj yeem txo qhov loj thiab qhov hnyav ntawm cov thav duab thaum tuav lawv lub zog. Bulkheads, uas cais cov khoom sib txawv thiab muab kev ruaj ntseg thiab kev nyab xeeb, feem ntau yog tsim los ntawm cov hlau no kom ntseeg tau tias lawv muaj kev ncaj ncees. Cov ncej yog siv los txhawb cov decks thiab cov khoom siv nyiaj siv ua haujlwm, thiab lub zog ntawm cov hlau phaj yog qhov tseem ceeb rau lawv cov khoom thauj - kev muaj peev xwm.
