Cov cuab yeej cuab tam thiab kev tsim khoom ntawm ABS Certificate A36 thiab AH36 Shipbuilding Steel Phaj

Nyob rau hauv lub realm ntawm shipbuilding, qhov zoo thiab kev ua tau zoo ntawm steel phaj yog qhov tseem ceeb heev. Ntawm ntau hom hlau phaj, ABS Certificate A36 thiab AH36 Shipbuilding Steel Phaj sawv tawm rau lawv cov khoom tshwj xeeb thiab cov txheej txheem ntau lawm.

Cov khoom siv hluav taws xob ntawm ABS Certificate A36 Shipbuilding Steel Phaj ua rau nws muaj kev ntseeg siab rau ntau daim ntawv thov kev tsim khoom. Nws feem ntau nthuav tawm lub zog tawm ntawm ib ncig ntawm 250 MPa thiab lub zog tensile xws li 400 txog 550 MPa. Lub elongation ntawm kev tawg yog kwv yees li 20% mus rau 23%, qhia tias nws cov ductility zoo thiab muaj peev xwm tiv taus deformation yam tsis tau tawg yooj yim. Cov khoom siv kho tshuab no ua rau lub phaj muaj peev xwm los tswj cov kev xav tau ntawm cov qauv thiab cov khoom hnyav uas tau ntsib hauv kev tsim nkoj.

Ntawm qhov tod tes, AH36 Shipbuilding Steel Phaj muaj kev txhim kho kev ua haujlwm zoo. Nws muaj lub zog tawm los ntau dua, feem ntau tshaj 355 MPa, thiab lub zog tensile nyob rau hauv thaj tsam ntawm 490 txog 620 MPa. Lub elongation ntawm kev tawg yog khaws cia ntawm qhov txaus siab, ua kom muaj zog thiab ductility. Qhov no ua rau AH36 haum rau cov cheeb tsam ntawm lub nkoj uas xav tau ntau dua cov qauv kev ncaj ncees thiab ua haujlwm rau cov khoom hnyav thiab hnyav marine.

Cov txheej txheem ntau lawm ntawm cov hlau daim hlau no yog ib qho nyuaj thiab tswj tau qib ntawm cov kauj ruam. Nws pib nrog kev xaiv cov khoom zoo raw, nrog rau cov hlau ore, coke, thiab alloying ntsiab. Cov ntaub ntawv raw yog melted nyob rau hauv lub moj tej tawg rauv nyob rau hauv ua tib zoo tswj tej yam kev mob kom ua tau raws li qhov xav tau cov tshuaj muaj pes tsawg leeg.

Tom ntej no, molten steel yog refined kom tshem tawm impurities thiab kho cov ntsiab lus alloy precisely. Cov txheej txheem refining no feem ntau suav nrog cov txheej txheem xws li ladle metallurgy thiab nqus degassing kom ntseeg tau tias homogeneity thiab purity ntawm cov hlau.

Tom qab refining, cov hlau yog cam khwb cia rau hauv slabs los yog paj. Cov txheej txheem casting yog ua tib zoo tswj los tswj tus nqi solidification thiab microstructure tsim, uas muaj kev cuam tshuam loj heev rau cov khoom siv hlau kawg ntawm cov phaj steel.

Cov khoom cam khwb cia tom qab kub dov, qhov uas lawv tau dhau los ntawm cov txheej txheem ntawm cov chais ntawm qhov kub thiab txias kom txo cov thickness thiab zoo li lub phaj. Intermediate annealing lossis normalizing kev kho mob tuaj yeem ua tiav thaum lub sijhawm no txhawm rau txhim kho microstructure ntxiv thiab txhim kho cov khoom siv kho tshuab.

Cov kauj ruam tom ntej ua tiav suav nrog kev ua kom txias txias, yog tias xav tau, kom ua tiav qhov kawg tuab thiab nto tiav. Cov txheej txheem kev kho cua sov xws li quenching thiab tempering kuj tseem yuav ua haujlwm los txhim kho cov khoom siv ntawm AH36 steel phaj, txhim kho nws lub zog thiab tawv.

Thoob plaws hauv cov txheej txheem tsim khoom, kev ntsuas kev tswj kom zoo yog siv rau txhua theem. Tshuaj lom neeg muaj pes tsawg leeg tsom xam, kev ntsuam xyuas cov cuab yeej cuab tam, thiab kev soj ntsuam tsis muaj kev puas tsuaj xws li kev ntsuam xyuas ultrasonic thiab kev soj ntsuam cov hlau nplaum yog siv los xyuas kom meej tias cov hlau phaj ua tau raws li cov qauv nruj raws li ABS thiab cov kev xav tau ntawm kev lag luam shipbuilding.

Hauv kev xaus, cov khoom siv ntawm ABS Certificate A36 thiab AH36 Shipbuilding Steel Phaj, nrog rau lawv cov txheej txheem ntau lawm, ua rau lawv cov ntaub ntawv tseem ceeb hauv kev tsim cov nkoj txhim khu kev qha thiab nyab xeeb. Kev nce qib tsis tu ncua hauv kev tsim khoom siv thev naus laus zis thiab kev tswj hwm zoo kom ntseeg tau tias cov ntawv hlau no txuas ntxiv ua kom tau raws li cov kev sib tw hloov zuj zus thiab cov qauv ntawm kev tsim cov nkoj niaj hnub no.
