Kev ua haujlwm ntawm P355GH Welded yeeb nkab tuaj yeem faib ua cov kev pabcuam kub ntev thiab luv luv kub raws li kev ua haujlwm, raws li hauv qab no:
1. Kev ntsuas kub thiab txias
| Yam Kub | Qhov ntsuas kub ntau | Kev Ua Tau Zoo Yuav Tsum Tau |
|---|---|---|
| Kev pabcuam ntev ntev | -10℃~ +400 degree | Tswj cov cuab yeej siv tau ruaj khov thiab cov creep |
| Lub sijhawm luv luv ntsuas kub | Tsawg dua los yog sib npaug rau 540 degree | Pub luv luv-ua haujlwm hnyav (xws li cov xwm txheej sib tsoo) |
2. Qhov kub-cuam tshuam txog kev ua haujlwm
Kev kub siab kub lub zog khaws nyiaj khaws cia:
300 degree: Tawm lub zog ntau dua los yog sib npaug 285 MPa (khaws ntau dua 80% ntawm chav nyob lub zog);
350 Qib: 10⁵ teev kev ua siab ntev ntev dua lub zog ntau dua los yog sib luag rau 110 MPa (tseem ceeb rau cov neeg nkag mus rau cov neeg nkag).
Tsawg kub kub ua tau lav:
-20℃cuam tshuam lub zog: ntau dua lossis sib luag rau 27 j (txhawm rau paub tseeb tias muaj peev xwm tiv taus brittle juracture nyob ib puag ncig me me).

3. Qhov kub txwv kev ceev faj
Tsawg tsawg kub qis dua:
Thaum qhov kev tsim tawm qhov ntsuas kub yog qis dua-10 degree, kev ntsuam xyuas ntxiv txog kev cuam tshuam rau qhov kub tsawg dua;
Kev kub siab loj tshaj:
Thaum siv rau lub sijhawm ntev ntawm> 400 degree, qib kev ntxhov siab yuav tsum tau tswj kom tsawg dua lossis sib npaug rau 80% ntawm qhov kub kom muaj zog;
Thaum cov khoom siv oxidation tus nqi nce ntau heev ntawm> 450℃(anti-corrosion txheej yuav tsum tau)
4. Cov ntaub ntawv raug xwm txheej ntawm kub
| Cov Ntawv Thov | Kev khiav hauj lwm kub | Rooj plaub |
|---|---|---|
| Lub Chaw Nres Tsheb Hluav Taws Xob Cov Hluav Taws Xob Cov Hluav Taws Xob | 300-400 degree | Supercritical chav nyob 540℃luv-lo lus sib tshooj |
| Cov Tshuaj Txhuam Reactor Thaum Tshav Kub Kub | 200-350 degree | Lub sijhawm ua haujlwm ntev hauv Sulphur-muaj qhov nruab nrab nruab nrab |
| DEJ NTSUAS | 280-400 degree | 100,000 teev lub neej ntawm lub neej ntawm 17.5MPA siab |
