Dab tsi yog qhov tsawg kawg nkaus lub zog thiab tensile zog yuav tsum tau rau SPA-H Corten Steel raws li tus qauv JIS G 3125? Cov lus nug no yog qhov tseem ceeb rau kev xaiv cov khoom siv, kev tsim qauv, thiab kev txheeb xyuas qhov zoo hauv cov haujlwm txawv teb chaws. Hauv qab no yog cov lus qhia luv luv uas qhia meej txog cov qauv kev qhia tshwj xeeb, cov ntawv tseem ceeb, thiab cov txheej txheem ua pov thawj kom ntseeg tau tias ua raws.
1. Cov ntsiab lus tseem ceeb: Yam tsawg kawg nkaus tawm los & Tensile Strength
JIS G 3125 tus qauv qhia meej meej lub zog txhua yam yuav tsum tau ua rau SPA-H Corten Steel, tsis muaj qhov sib txawv raws qhov tuab (rau cov ntsuas ntau yam 3-20mm):
Yam tsawg kawg nkaus Yield Strength (YS): Ntau dua lossis sib npaug rau 345 MPa (megapascals). Qhov no yog qhov tseem ceeb tshaj plaws rau kev tiv thaiv kom tsis txhob deformation nyob rau hauv load, tshwj xeeb tshaj yog ib qho tseem ceeb rau load- bearing yam ntxwv yam (xws li, kab teeb, kab).
Yam tsawg kawg Tensile Strength (TS): 480 - 620 MPa. Qhov no yog hais txog qhov siab tshaj plaws ntawm cov khoom siv tuaj yeem tiv taus ua ntej tawg, ua kom muaj kev ncaj ncees hauv cov khoom hnyav.
Cov lus ceeb toom ntxiv: JIS G 3125 kuj yuav tsum tau SPA-H kom muaj qhov tsawg kawg nkaus elongation ntawm Greater dua lossis sib npaug li 21% (rau cov qauv nrog qhov ntev ntawm 50mm), uas zoo sib xws rau lub zog thiab ua kom cov khoom siv ductility rau kev ua haujlwm (xws li, khoov, vuam).
2. Cov Lus Qhia Tseem Ceeb ntawm Kev Xav Tau Lub Zog
Tsis muaj Thickness -Txoj kev txo qis: Tsis zoo li qee cov qib steel, SPA-H qhov tsawg kawg nkaus yield thiab tensile zog yuav tsum tsis txhob txo nrog nce thickness (hauv 3-20mm). Qhov no ua kom yooj yim cov qauv tsim thiab kev tswj kom zoo rau cov haujlwm txawv teb chaws siv cov khoom siv sib xyaw.
Kev kho cua sov cuam tshuam: SPA-H feem ntau yog muab los ua kub- dov steel. Ib qho kev tshaj tawm -kev kho cua sov (piv txwv li, rau vuam lossis kev sib sau) yuav tsum tsis txhob siab tshaj 600 degree, vim tias qhov kub thiab txias tuaj yeem txo nws lub zog qis dua tus qauv yuav tsum tau ua.
3. Cov txheej txheem ua pov thawj rau kev xa khoom txawv teb chaws
Txhawm rau kom ntseeg tau tias SPA yuav khoom-H ua tau raws li qhov yuav tsum tau muaj zog, ua raws li ob kauj ruam pov thawj tseem ceeb no:
Mill Test Report (MTR) Review: Thov MTRs los ntawm tus neeg muag khoom rau txhua tus xov tooj cua sov. Paub meej tias cov txiaj ntsig thiab tensile lub zog qhov tseem ceeb tau teev tseg los yog tshaj qhov tsawg kawg nkaus yuav tsum tau (YS Ntau dua lossis sib npaug rau 345MPa, TS 480-620MPa). Xyuas kom lub MTR dais lub zeb lub thwj cim thiab phim cov khoom cov khoom kub thiab specifications.
Thib peb-Kev kuaj xyuas tog neeg: Rau cov haujlwm tseem ceeb (piv txwv li, cov qauv hauv ntug dej hiav txwv, cov tsev loj -} nplai), tso siab rau cov koom haum kuaj thoob ntiaj teb (xws li, SGS, BV) los ua rau - qhov chaw sampling thiab tensile tests. Qhov no txheeb xyuas qhov tseeb ntawm MTR thiab ua kom cov khoom sib xws.
Cov lus qhia rau Cov Ntawv Thov Kev Pabcuam Txawv Tebchaws
Qhia meej meej txog JIS G 3125 lub zog yuav tsum tau muaj nyob rau hauv daim ntawv cog lus yuav khoom, thiab ntxiv cov nqe lus uas yuav tsum tau tus neeg muag khoom tau txais kev lav phib xaub rau cov khoom tsis raug cai (piv txwv li, xa rov qab, nyiaj them poob haujlwm).
Thaum tsim cov load-cov kabmob, tsis txhob siv qhov tsawg kawg nkaus lub zog qhov tseem ceeb ncaj qha-tso tseg qhov kev nyab xeeb (feem ntau yog 10-15%) los suav rau ib puag ncig (xws li, corrosion, tsis tshua muaj kub) hauv kev pabcuam ntev.
Hauv cov ntsiab lus, SPA-H Corten Steel qhov tsawg kawg nkaus lub zog yuav tsum tau ua rau JIS G 3125 yog Ntau dua lossis sib npaug rau 345MPa rau lub zog tawm los thiab 480-620MPa rau lub zog tensile. Kev soj ntsuam nruj me ntsis ntawm cov ntsuas no los ntawm MTR kev tshuaj xyuas thiab kev ntsuas ntsuas ua kom cov khoom ua tau raws li qhov kev nyab xeeb thiab kev ua haujlwm xav tau hauv cov ntawv thov txawv teb chaws.
