A516Gr70 {- Hlau {}}}} Tus neeg siv phau ntawv qhia.pdf
A516Gr70 yog ib tug pa roj carbon steel phaj rau cov vesss kub thiab qis kub nyob hauv qab Astm tus qauv. Nws yog dav siv vim nws qhov kev ua tau zoo vuam ua tau zoo, qis - kub ua thiab lub zog compressive. Cov tshuaj lom neeg tshuaj lom neeg yog C tsawg dua lossis sib npaug nrog 0.035%, nrog tensile lub zog ntau dua lossis sib npaug nrog 260 MPa.
Ceev faj rau kev siv
1. Vuam Cov Txheej Txheem Tswj Xyuas
Tsawg - hydrogen electrodes (xws li E7018) yuav tsum tau siv thiab pre-00℃((rau cov phaj tuab ntau dua lossis sib npaug nrog kev tawg.
Nws raug nquahu kom ua kev ntxhov siab annealing ntawm 600 - 620℃tom qab vuam (tshwj xeeb tshaj yog rau cov phaj nrog lub thickness loj tshaj 30mm).
2. Daim ntawv thov nyob rau hauv qis-} qhov chaw ib puag ncig
Nws ua tau zoo nyob rau hauv ib puag ncig saum - 30 degree. Txawm li cas los xij, rau qhov ntsuas kub hauv qab no, cov txiaj ntsig ntawm Charpy V-Meych cuam tshuam kev ntsuas (feem ntau yuav tsum muaj ntau dua los yog sib npaug ntawm 5J ntawm -30 degree).
3. Ua thiab sib sau
Thaum txias - bading, nws raug nquahu tias kev khoov ntsuas hluav taws xob tsawg dua ob zaug lub phaj tuab kom tsis txhob muaj cov kab nrib pleb.
Qhov kub ua ntsuas kub yuav tsum tau tswj tsis pub dhau 900-950℃kom zam cov qoob loo grainening los ntawm overheating.
4. Kev tiv thaiv corrosion
Tsis - huab cua huab cua yuav tsum tau coated nrog epoxy thee painings (xws li epoxy thee pil enamel pleev xim) hauv epoxy plooj av enamel) hauv -}}}}}} muaj ib puag ncig.
5. Cia thiab tuav
Zam kev sib cuag nrog chlorides (xws li salts). Khaws rau ntawm pallets los tiv thaiv ya raws.
Raug Daim Ntawv Teev Lus
Siab Hlaws Raug
Petrochemical Kev Lag Luam: Cov hlab ntsha cov tshuaj tiv thaiv, distillation yees (kev ua haujlwm kub -30 txog 400 degree).
Linefied roj tso tsheb hlau luam (yuav tsum ua raws li ASME Seem VIII Cov Qauv).
2. Cov khoom siv zog zog
Cov khoom siv Boiler Chav, Nuclear Zog Ua Khoom Siv (Tsis {{0} Badiation cheeb tsam).
3. Cov Txheej Txheem
Choj bearings, loj- nplai stand qauv steel qauv (xav tau anti- corrosion tsim).
Tuam Tshoj ib {- nres hlau ua khoom siv
Los ntawm xyoo ntawm kev nkag siab thiab nag lossis daus ntawm cov hlau, pab lwm cov khoom lag luam, muab ntau yam qauv tsim kho thoob ntiaj teb. Ua tsaug rau Yuxin Group txoj kev tshaj lij thiab kev ncaj ncees, nws tau dhau los ua lub ntiaj teb -} lub npe nrov lag luam.
