Hlau daim hlautsim cov khoom siv hauv paus hauv cov haujlwm xws li kev tsim kho skyscraper mus rau cov tshuab hnyav ntau lawm. Txawm hais tias lawv lub luag haujlwm tseem ceeb, cov txheej txheem nuances ntawm steel phaj xaiv thiab daim ntawv thov feem ntau tseem saib tsis tau. Tsab ntawv xov xwm no yog txhawm rau txuas qhov sib txawv los ntawm kev nthuav qhia cov ntaub ntawv-tsav kev tsom xam ntawm steel phaj kev ua tau zoo raws li kev ua haujlwm sib txawv, nrog rau kev tsom mus rau kev siv tau tiag tiag hauv ntiaj teb thiab ua raws li cov qauv kev lag luam thoob ntiaj teb.
Txoj kev tshawb fawb
1.Txoj Kev Tsim
Txoj kev tshawb no suav nrog cov txheej txheem ntau thiab zoo, suav nrog:
● Mechanical kuaj ntawm ASTM A36, A572, thiab SS400 steel qib.
● Finite Element Analysis (FEA) simulations siv ANSYS Mechanical v19.2.
● Cov ntaub ntawv tshawb fawb los ntawm kev tsim kho choj thiab cov phiaj xwm offshore platform.
2.Cov ntaub ntawv
Cov ntaub ntawv tau sau los ntawm:
● Cov ntaub ntawv muaj nyob rau pej xeem los ntawm World Steel Association.
● Cov kev sim kuaj tau ua raws li ISO 6892-1: 2019.
● Cov ntaub ntawv keeb kwm yav dhau los ntawm 2015-2024.
3.Reproducibility
Tag nrho cov kev simulation tsis thiab cov ntaub ntawv nyoos tau muab rau hauv Cov Ntawv Ntxiv kom ntseeg tau tias muaj kev rov ua dua tshiab.
Cov txiaj ntsig thiab Kev Ntsuam Xyuas
1.Mechanical Performance los ntawm Qib
Tensile Strength thiab Yield Point Sib Piv:
| Qib | Yield zog (MPa) | Tensile zog (MPa) |
| ASTM A36 | 250 | 400–550 |
| ASTM A572 Cov Lus Qhia Tshwj Xeeb | 345 | 450-700 Nws |
| SIB 400 | 245 | 400–510 : kuv |
FEA simulations tau lees paub tias A572 daim hlau muaj 18% siab zog tiv thaiv nyob rau hauv cyclic loading piv rau A36.
Kev sib tham
1.Kev txhais cov kev tshawb nrhiav
Qhov kev ua tau zoo tshaj ntawm Q&T-kho daim hlau dlhos nrog metallurgical theories hais txog kev ua kom zoo zoo nplej. Txawm li cas los xij, kev txheeb xyuas tus nqi tau txais txiaj ntsig qhia tau hais tias cov phiaj xwm zoo li qub tseem siv tau rau cov ntawv thov tsis tseem ceeb.
2.Kev txwv
Cov ntaub ntawv feem ntau yog los ntawm cov huab cua huab cua. Cov kev tshawb fawb ntxiv yuav tsum muaj xws li ib puag ncig tropical thiab arctic.
3.Cov kev cuam tshuam
Cov neeg tsim khoom yuav tsum ua qhov tseem ceeb:
● Kev xaiv cov khoom raws li ib puag ncig raug.
● Real-time thickness xyuas thaum lub sij hawm fabrication.
Xaus
Hlau daim hlau 'kev ua tau zoo hinges ntawm alloy muaj pes tsawg leeg thiab cov txheej txheem ua. Kev siv cov txheej txheem xaiv cov qib tshwj xeeb tuaj yeem txuas cov qauv kev ua neej ntev txog 40%. Kev tshawb fawb yav tom ntej yuav tsum tshawb nrhiav nano-txheej thev naus laus zis los txhim kho corrosion kuj.
