Preheating Specifications los ntawm Phaj Thickness (Cov qauv dav dav rau cov nkoj siab)
Thickness <25 hli:Tsis tas yuav tsum tau preheating ntawm ambient kub tshaj 5 degree; Thaum lub ambient kub yog qis dua 0 degree, preheat rau qhov tsawg kawg nkaus ntawm 50℃los tiv thaiv brittle fracture vim ceev ceev.
Thickness 25-50 hli:Yuav tsum preheating rau 50-100 degree; heat uniformly nyob rau hauv ib tug 75 hli ntau yam ntawm ob sab ntawm weld. Thaum lub sij hawm multi- hla welding, qhov kub ntawm interpass yuav tsum tsis txhob poob qis dua 50℃.
Thickness > 50 hli:Yuav tsum tau preheating rau 100-150 degree; siv ib daim pam cua sov kom zoo ib yam preheating ntawm tag nrho cov seem; tswj qhov ntsuas kub ntawm 100-200 degree; yog tias qhov kub thiab txias poob qis dua, rov ua dua ua ntej txuas ntxiv vuam.
Cov ntsiab lus tseem ceeb ntxiv rau Vuam
Tswj lub siab txwv ntawm qhov ntsuas kub ntawm 250 degree; Kev kub siab heev tuaj yeem ua rau cov nplej coarsening hauv tshav kub- thaj tsam cuam tshuam, cuam tshuam qhov tseem ceeb ntawm SA612 qhov zoo-grained qis- kub cuam tshuam toughness;
Rau cov khoom siv nrog lub thickness ntawm 32 hli los yog ntau dua kev khiav hauj lwm nyob rau hauv qis - kub, siab - siab tej yam kev mob, post-weld stress- kev kho cua sov yog pom zoo: tuav ntawm 590-650℃rau 1 teev ib 25 hli thickness, ua raws li los ntawm qeeb txias nrog rau lub cub tawg kom tshem tawm cov residual welding;
Rau cov phaj tuab 25 hli lossis siab dua, nws raug nquahu kom cia lub vuam sawv ntsug rau 24 teev ua ntej ua MT / UT uas tsis yog- kuaj kev puas tsuaj kom tsis txhob muaj kev ncua hydrogen- ua rau cov kab mob khaub thuas.
ASME SA612 vs SA516 Qib 70: Siab zog
| Qib | Yam tsawg kawg nkaus Yield Strength |
|---|---|
| TIAB SA 516 Gr70 | 260 MPa |
| SIB 612 | 345 MPa ua |
SA612 nta ntau dua qhov tsawg kawg nkaus tawm lub zog piv rau SA516 Gr70 cov pa roj carbon nkoj phaj, nqa ntau tus nqi & cov qauv zoo rau cov tuam txhab siab:
Kev tsim kev ntxhov siab ntau dua Raws li kev tsim qauv siab, tsim qhov kub thiab txias ntawm lub nkoj, SA612 tuaj yeem ua rau muaj kev ntxhov siab ntau dua li ASME VIII code. Nws ua tau raws li siab -siab ua hauj lwm yuav tsum tsis muaj oversize cov khoom xaiv.
Txo cov phaj thickness Ua tsaug rau nws 345 MPa tawm los lub zog, cov neeg tsim qauv tuaj yeem siv cov phab ntsa tuab dua qub rau lub plhaub thiab lub taub hau, thaum tseem txaus siab rau cov qauv kev nyab xeeb. Cov phaj tuab tuab nrog cov khoom kim heev thiab cov nqi ua haujlwm siab tuaj yeem zam tau.
Cov khoom siv sib dua tag nrho qhov hnyav Nyias steel phaj loj heev txiav qhov hnyav tuag ntawm cov hlab ntsha ua tiav. Nws txo cov nqi tsheb thauj mus los, nqa cov nqi thiab kev tsim kho hauv paus rau cov neeg siv kawg.
