Kev soj ntsuam ntawm Kev Ua Haujlwm Zoo Ib puag ncig ntawm S690QL1 tsis tshua muaj siab kub siab lub nkoj steel phaj

Hauv cov xwm txheej xws li kev siv roj thiab roj, kev khaws tshuaj thiab kev thauj mus los hauv cheeb tsam polar thiab alpine,S690QL1 tsis tshua muaj siab siab lub nkoj steel phajtau dhau los ua cov khoom siv tseem ceeb rau kev tsim khoom qis -kub siab cov hlab ntsha vim nws qhov zoo heev uas tsis tshua muaj - kub toughness. Piv nrog rau cov phaj siab zoo tib yam steel phaj, S690QL1 (L1 nruab nrab yog qis- qib kub) tuaj yeem tswj tsis muaj kev pheej hmoo ntawm pob txha tawg hauv qhov tsis tshua muaj siab - qhov kub thiab txias ntawm -40℃. Nws cov txiaj ntsig kev ua tau zoo yog los ntawm kev tswj cov khoom muaj pes tsawg leeg thiab cov txheej txheem kev kho cua sov kom nruj.

Ua ntej,los ntawm qhov kev xav ntawm kev tsim qauv, S690QL1 nruj me ntsis tswj cov ntsiab lus ntawm cov khoom tsis zoo xws li phosphorus (P Tsawg dua lossis sib npaug li 0.025%) thiab leej faj (S Tsawg dua lossis sib npaug li 0.015%) - cov ntsiab lus no feem ntau ua rau cov khoom tawg yooj yim hauv qis - qhov kub thiab txias hauv ib puag ncig, low-kub toughness ntawm cov khoom. Nyob rau tib lub sijhawm, npib tsib xee (Ni tsawg dua lossis sib npaug li 2.0%) yog ntxiv los txhim kho qis -kub toughness, thiab nws yog synergistically ntxiv dag zog rau cov ntsiab lus xws li manganese thiab molybdenum. Qhov no enablesS690QL1 tsis tshua muaj siab siab lub nkoj steel phajkom ua tau raws li lub zog tawm los ntawm 690MPa thaum muaj qhov qis - qhov kub thiab txias ntawm lub zog (-40 degree) Ntau dua lossis sib npaug rau 60J, deb tshaj qhov yuav tsum tau ua ntawm cov khoom siv hluav taws xob qis qis qis qis steel (kev cuam tshuam lub zog loj dua lossis sib npaug rau 27J).

• Tshuaj muaj pes tsawg leeg rau S690QL1 Steel Phaj

Hauv kev kho cua sov,S690QL1 tsis tshua muaj siab siab lub nkoj steel phajtxais yuav ob-theem "quenching + tempering" kev kho: qhov kub thiab txias yog tswj ntawm 880-950℃kom siab homogenize austenite, thiab martensitic matrix yog tsim tom qab txias ceev; tempering kub yog teem rau ntawm 550-650℃kom tshem tawm quenching nyob rau hauv kev nyuaj siab thiab precipitate nplua carbonitrides, uas tsis tsuas yog ua kom lub zog tab sis kuj txhim kho toughness. Cov txheej txheem no tswj cov qoob loo loj ntawm cov khoom siv saum toj no qib 6, thiab cov qauv zoo -grained ntxiv txhim kho qhov kub-kub los tiv thaiv cov pob txha tawg.

Hauv qhov sib piv, qhov cuam tshuam lub zog ntawm aboiler steel phajntawm tib lub thickness nyob rau hauv tib qhov chaw tsuas yog 22J, uas yog nyob ze rau qhov tseem ceeb ntawm cov pob txha tawg.

Ntxiv rau qhov qis -kub toughness,S690QL1 tsis tshua muaj siab siab lub nkoj steel phajkuj muaj zoo weldability. Thaum vuam nrog qis -hydrogen electrodes (xws li E9018-G), qhov kub thiab txias tau tswj tau ntawm 100-150 degree, thiab kev kho kev ntxhov siab ntawm 200-250℃yog ua tom qab vuam, uas tuaj yeem ua tau zoo kom tsis txhob muaj qhov kub thiab txias ntawm vuam sib txuas. Nyob rau tib lub sijhawm, nws muaj qhov sib txuam siab ntawm cov txiaj ntsig ntawm lub zog thiab lub zog tensile (yield ratio Tsawg dua lossis sib npaug li 0.85), thiab tuaj yeem nqus tau kev ntxhov siab hauv qhov kev hloov pauv siab kom tsis txhob muaj kev cuam tshuam hauv zos ntawm lub nkoj.

Hais txog cov qauv ntsuas rau qis -kub siab cov hlab ntsha,S690QL1 tsis tshua muaj siab siab lub nkoj steel phajyuav tsum xeem dhau ntau yam kev xeem xws li Charpy V-kev ntsuas qhov cuam tshuam, Ultrasonic Testing (UT), thiab Sib Nqus Particle Testing (MT) kom tsis txhob muaj qhov tsis xws luag.
