Taw qhia
Corten B Steel Phaj yog cov khoom kub dov ntawm cov qauv hlau hauv kev xa khoom nrog kev txhim kho atmospheric corrosion kuj.
Cov hlau qib Corten B yog raws li ASTM tus qauv uas muaj lub zog tawm los ntawm 355MPa thiab 345MPa uas yog raws li qhov sib txawv thickness.
Corten B - huab cua tiv taus hlau uas zoo dua rau cov qauv hnyav thiab thauj khoom.
Cov khoom tsim nws tus kheej tiv thaiv txheej thaum raug rau atmospheric ntsiab. Qhov tseem ceeb, txheej sab saum toj corrodes uas tom qab ntawd tiv thaiv cov hlau hauv qab nws. Lub ntuj tiav tsis tas yuav tsum muaj kev saib xyuas xws li kev pleev xim, uas ua rau cov khoom siv tau zoo heev rau lwm cov qauv hlau.
Kev pleev xim thiab kev saib xyuas yuav xav tau yog tias cov qauv tseem ntub tas li vim tias cov txheej txheem tiv thaiv yuav tsis tsim. Ib qho piv txwv zoo yog qhov twg lub hauv paus ntawm cov qauv sib ntsib nrog hauv av los yog ib nrab submerged.
Vuam txoj kev
| Vuam txoj kev | Haum Thickness | Cov ntsiab lus tseem ceeb |
|---|---|---|
| SMAW (Shielded Hlau Arc Vuam) | >10 hli | Siv tsawg-hydrogen electrodes sib xws nrogCorten B, tswj cov cua kub nkag |
| GMAW (Gas Metal Arc Welding) | 5-20 hli | Muab cov hlaws zoo sib xws thiab kev tsim khoom sai |
| GTAW / TIG (Gas Tungsten Arc Welding) | <10mm | Precise tswj, txo warping ntawm nyiashuab cua steel |
Kev soj ntsuam:Kev siv vuam kom zoo95-100% ntawm lub hauv paus hlau zogthaum khaws cia tsim patina.
Preheating thiab cua sov tswj
Preheat kub: 100–150°C for plates >20 hli
Interpass Kub:Khaws 150-250 degree
Thaum tshav kub kub input Control:Zam kom tsis txhob muaj cua sov ntau dhau los tiv thaiv micro- tawg thiab txheej txheej xeb tsis sib xws
Kev nkag siab ntawm cov ntaub ntawv:Tswj cua sov txoncej-weld crackingqhov tshwm sim dhau los30%, kom ntseeg tau tias zoo ib yamxeb-resistant steel phajkhoom.
Cov lus pom zoo ua haujlwm
| Hom kev ua haujlwm | Kev pom zoo | Sau ntawv |
|---|---|---|
| Txiav | Plasma lossis laser txiav nyiam dua | Txo cov cua sov- thaj tsam cuam tshuam, tiv thaiv kev cuam tshuam |
| Khoov | Yam tsawg kawg khoov vojvoog Ntau dua lossis sib npaug rau 1.5 × tuab | Tsis txhob tawg los yog qhov chaw puas |
| Drilling / Punching | Cov cuab yeej ntse thiab qeeb qeeb | Tiv thaiv burrs thiab khaws cia corrosion kuj |
Ncej - Weld thiab Post- Kev Kho Mob
Kev tshem tawm cov khib nyiab:Maj mam tshem tawm slag yam tsis muaj cov cuab yeej abrasive
Patina Development:Tawm welds lossis txiav ib txwm tsim cov txheej txheem tiv thaiv xeb hauv 6-12 lub hlis
Kev tshuaj xyuas:Siv NDT txoj kev zoo li ultrasonic lossis sib nqus particle kuaj kom muaj kev ncaj ncees yam tsis muaj kev puas tsuaj patina
Cov ntaub ntawv siv:Kev sim teb hauv thaj chaw muaj kev lag luam qhia tau tias ua tau zoo -Corten B steel phajtswj tshaj90% ntawm thawj corrosion kujtom qab 20 xyoo.
Kev siv vuam zoo thiab kev ua haujlwm yog qhov tseem ceeb rau kev ua kom zoo tshaj plaws ntawm cov qauv thiab corrosion-cov khoom zoo ntawmCorten B steel phaj.
Preheating, tswj cua sov, tsim nyog electrodes, thiab ua tib zoo ua cov txheej txheem ua kom ntev -lub sij hawm durability, tsawg kawg nkaus tu, thiab aesthetic patina tsim.
Ua raws li cov kev coj ua no tau lees tias siab - zoo, qis- tuhuab cua steelcov qauv tsim nyog rau kev txuas hniav, kev lag luam moj khaum, thiab sab nraum zoov architectural tej yaam num.
