Corten steel, ua kev zoo siab rau nws cov rustic tsos thiab corrosion kuj, yog ib qho kev xaiv nrov rau txuas hniav, facades, thiab sculptures. Tab sis thaum xav txog nws rau thawj qhov kev thauj khoom-cov qauv coj mus rau hauv qhov chaw xws li Northern Canada lossis Scandinavia, qhov twg qhov kub tuaj yeem poob mus rau -30 degree, cov lus nug tseem ceeb tshwm sim: nws puas muaj kev nyab xeeb thiab siv tau?
Cov lus teb luv luv yog:Yog, tab sis nrog kev ceev faj txog engineering tseem ceeb.Tus qauv, cov qib uas muaj nyob hauv Corten (xws li SPA-H, ASTM A588) tsis tuaj yeem haum rau huab cua txias.
Qhov Kev Sib Tw Core: Tsawg-Tsub Toughness
Qhov kev txhawj xeeb tseem ceeb tsis yog lub zog, tab sistawv- cov khoom muaj peev xwm nqus tau lub zog thiab tiv thaiv kev tawg thaum muaj kev cuam tshuam lossis kev ntxhov siab. Txhua steels undergo aDuctile -rau -Brittle Transition (DBT). Hauv qab qhov kub thiab txias, lawv tuaj yeem ua rau nkig tawg, ib qho kev ua tsis tiav tam sim nrog kev ceeb toom me ntsis.
Standard Corten steels muaj qhov kub thiab txias DBT. Thaum -30 degree, lawv qhov toughness tuaj yeem raug txo kom tsawg, ua rau muaj kev pheej hmoo rau cov tswv cuab ntawm cov qauv tsim muaj zog los yog muaj kev ntxhov siab heev.
Cov kev ceev faj tseem ceeb rau kev siv nyab xeeb
Qhia Qib Siab:Qhov no yog qhov tseem ceeb. Koj yuav tsum xaiv ibsub-qib tshwj xeeb tsim kho rau qis- kev pabcuam kub. Nrhiav cov npe xws li:
ASTM A588 Qib K(zoo dua qis-kub muaj peev xwm cuam tshuam ntau dua li qib qauv).
Tshwj xeeb normalized dov txheej txheemuas refine lub grain qauv los txhim kho toughness.
Kev lees paub meej ntawmCharpy V-Notch (CVN) cuam tshuam qhov tseem ceebntawm koj qhov ntsuas qhov tsawg kawg nkaus (piv txwv li, -30℃lossis qis dua). Cov ntaub ntawv xeem cov ntaub ntawv yuav tsum ua pov thawj txaus absorbed zog.
Tsim nrog nthuav dav hauv siab:
- Tsis txhob Notches thiab ntse Corners:Stress concentrators yog cov ntsiab lus pib rau cov kab nrib pleb. Siv cov kev hloov du thiab nthuav dav cov pob qij txha kom zoo.
- Nce Cov Qauv Tsim:Cov kws tshaj lij tuaj yeem siv ntau qhov kev nyab xeeb kev nyab xeeb rau kev sib txuas tseem ceeb thiab cov tswv cuab.
- Xav txog Load Hom:Dynamic, seismic, lossis siab - kev cuam tshuam kev thauj khoom yuav tsum tau tshuaj xyuas ntxiv piv rau cov khoom zoo li qub.
Fabrication & Vuam Expertise:
- Cov txheej txheem vuam (WPS)yuav tsum tsim nyog rau qib qis -kub. Siv cov khoom siv sib txuam lossis tshwj xeeb uas tau xaiv cov khoom siv vuam uas tsim cov hlau uas muaj zog sib npaug los yog zoo dua li cov phaj hauv qab.
- Kev ntxhov siab -Relieving:Tom qab-weld heat treatment tej zaum yuav tsim nyog rau cov ntu tuab kom txo tau cov kev ntxhov siab uas nyob rau hauv uas tuaj yeem ua ke nrog qis - kub embrittlement.
Hauv -Kev xav txog kev pabcuam:
- Patina Factor:Cov txheej tiv thaiv xeb (patina) tsim maj mam hauv cov huab cua txias, qhuav. Thawj qhov dej staining tseem tuaj yeem tshwm sim.
- Kev tshuaj xyuas:Kev tshuaj xyuas tsis tu ncua rau kev pib tawg, tshwj xeeb tshaj yog nyob rau hauv kev sib txuas, yog qhov ua tau zoo nyob rau hauv qhov chaw hnyav tshaj plaws.
- Xaus:Ib qho kev xaiv Engineered, tsis yog qhov qub
SPA-H Corten steel tuaj yeem siv tau zoo rau kev thauj khoom-cov kabmob hauv -30℃ib puag ncig, tab sis nws yuav tsum yogtxhob txwm tshaj tawm, teev kev xaiv, tsis yog tawm ntawm - lub - txee ib qho. Qhov tseem ceeb yog kev yuav cov khoom pov thawj qis- qhov kub thiab txias thiab koom tes nrog engineers thiab fabricators tau ntsib hauv Corten thiab txias - cheeb tsam tsim.
Ib txwm saib xyuas qhov tseem ceeb ntawm cov ntaub ntawv pov thawj cov ntaub ntawv xeem dhau qhov kev xav. Los ntawm kev ua raws li cov kev ceev faj no, koj tuaj yeem ua tiav ob qho tib si lub cim zoo nkauj ntawm Corten thiab tsis yog - qhov yuav tsum tau sib tham txog kev nyab xeeb ntawm cov qauv hauv qhov txias.
