Thaum muab S335J0WP Corten Steel, qhia meej txog nws cov xwm txheej xa khoom (piv txwv li, kub- dov, thermo- tshuab dov) yog qhov tseem ceeb rau kev sib piv cov kev xav tau tom qab ua tiav-xws li kev tsim, vuam, lossis kev teeb tsa ncaj qha - thiab ua kom cov haujlwm ua haujlwm tau zoo. Txawm li cas los xij, raws li S335J0WP tsis yog qib qauv, tsis muaj cov lus qhia tshwj xeeb rau nws cov khoom xa tuaj, ua rau cov neeg yuav khoom tsis paub meej tias cov kev xaiv twg yog qhov zoo. Daim ntawv xa tuaj ntawm qib no yog dab tsi, thiab yuav xaiv lawv li cas? Lub ntsiab lus qhia ua ntej:S335J0WP tsis tau teev nyob rau hauv EN 10025-5 (lub ntsiab European qauv rau Corten Steel). Peb muab cov khoom xa tuaj raws li nws cov khoom pov thawj (tshwj xeeb tshaj yog cov lus "P") thiab European Corten Steel's universal delivery standards. Hauv qab no yog cov ntsiab lus, pov thawj -raws li kev tawg.
Lub Ntsiab Lus Tseem Ceeb: Qib Nature & Kev Xa Khoom Siv Hauv paus
Txhawm rau kom ntseeg tau tias muaj txiaj ntsig ntawm kev tshuaj xyuas, ob lub ntsiab lus tseem ceeb yuav tsum tau qhia meej ua ntej:
Qib Inference: Raws li European steel naming conventions, S335J0WP yog nruab nrab - tsis tshua muaj zog Corten Steel (yield zog ~ 235-}335MPa) nrog "W" ( huab cua tsis kam), "P" (thermo- tshuab dov), thiab "J0" (20℃J0) toughness ntau dua 2. Nws ua raws li EN 10025-5's design logic rau huab cua-resistant steels tab sis tsis muaj kev cai txheem.
Delivery Condition Definition: Kev xa khoom xa mus rau lub xeev ua haujlwm ntawm cov hlau ua ntej xa khoom, uas cuam tshuam ncaj qha rau nws cov khoom siv kho tshuab (lub zog, ductility) thiab nto zoo. Rau Corten Steel, cov xwm txheej kev xa khoom ntau yog txhais los ntawm European cov qauv (EN 10025 series) thiab kev coj ua lag luam, tsom rau cov txheej txheem dov thiab kev kho cua sov.
Kev xa khoom ntau rau S335J0WP Corten Steel
Raws li "P" suffix (thermo-mechanical dov) hauv S335J0WP lub npe qib thiab kev ua lag luam rau cov huab cua zoo sib xws-cov hlau tsis muaj zog, cov hauv qab no yog cov khoom xa tuaj ntau tshaj plaws, txheeb los ntawm kev siv tau:
1. Thermo-Mechanically Rolled (TMR, cim raws li "P") - Feem ntau Hom
Txheej txheem piav qhia: Qhov no yog qhov kev xa khoom tsis zoo uas tau hais los ntawm "P" suffix. Cov hlau yog dov ntawm qhov ntsuas kub (850-1050 degree) thiab txias sai sai tom qab dov, tsis muaj kev kho cua sov ntxiv. Cov txheej txheem no refines grain qauv, ntsuas lub zog thiab ductility.
Cov yam ntxwv tseem ceeb: Yield zog ~ 235-335MPa, zoo ductility (elongation Ntau dua los yog sib npaug rau 22%), thiab cov khoom zoo li qub. Nto zoo zoo dua li kub-kuav los tiag (HR) steel, tsis muaj qhov pom tseeb. Nws ua tau raws li "J0" 20℃cuam tshuam toughness yuav tsum tsis muaj kev kho cua sov ntxiv.
Siv tau Scenarios: Haum rau feem ntau cov ntawv thov, xws li kev txhawb nqa kev lag luam, cov khoom tsim vaj tsev, thiab nruab nrab -gauge daim hlau (6-25mm) uas yuav tsum tau ua ncaj qha los yog vuam yam tsis muaj kev kho cua sov ua ntej.
2. Kub-Rolled (HR) - Nqis -Txoj Kev Xaiv Zoo
Txheej txheem piav qhia: Cov hlau yog dov ntawm qhov kub thiab txias (siab dua qhov kub ntawm recrystallization, ~ 1000-1200 degree) thiab txias lawm tom qab dov, tsis muaj kev tswj cua txias lossis kev kho cua sov ntxiv.
Cov yam ntxwv tseem ceeb: Tus nqi tsim khoom qis dua TMR. Lub zog tawm los qis dua me ntsis (~ 235-315MPa) tab sis tseem ua tau raws li qhov xav tau ntawm lub zog nruab nrab. Qhov saum npoo yuav muaj txheej nyias ntawm oxide nplai (mill scale), uas yuav tsum tau ntxuav ua ntej vuam lossis pleev xim. Ductility qis dua me ntsis (elongation Ntau dua lossis sib npaug li 20%) dua TMR.
Siv tau Scenarios: Suitable for non-critical load-bearing components, thick-gauge plates (>25mm), los yog tej yaam num nrog nruj nqi pob nyiaj siv. Yuav tsum tau ntxuav qhov chaw (piv txwv li, txhaj tshuaj blasting) ua ntej tom qab ua tiav.
3. Normalized (N) - Rau Siab -Cov Kev Xav Tau Ua Tau Zoo
Txheej txheem piav qhia: Cov hlau yog rhuab mus rau 890-950℃(austenitization kub) tom qab dov, tuav ntawm qhov kub no rau ib lub sijhawm, thiab tom qab ntawd txias hauv huab cua. Cov txheej txheem no tshem tawm cov kev ntxhov siab sab hauv thiab ua kom cov qauv zoo ib yam.
Cov yam ntxwv tseem ceeb: Qhov siab tshaj plaws ductility (elongation Ntau dua lossis sib npaug li 24%) ntawm peb qhov xwm txheej, nrog kev ruaj khov 20℃cuam tshuam toughness (Ntau dua lossis sib npaug rau 30J). Lub zog tawm los zoo ib yam li TMR (~ 235-335MPa), tab sis kev ntxhov siab sab hauv yog qhov qis dua, txo qhov kev pheej hmoo tawg thaum lub sij hawm tsim.
Siv tau Scenarios: Suitable for components requiring complex forming (e.g., curved beams, special-shaped brackets) or thick-gauge plates (>20mm) uas xav tau siab ductility kom tsis txhob ua cov kab nrib pleb.
Cov txheej txheem tsim khoom & Kev Tshawb Fawb
Qhia meej txog qhov xav tau ntawm kev xa khoom: Qhia meej meej txog yam khoom xa tuaj (TMR/P, HR, lossis N) hauv daim ntawv cog lus yuav khoom. Rau feem ntau cov haujlwm, TMR / P yog qhov kev xaiv zoo tshaj plaws vim nws qhov kev ua tau zoo thiab tus nqi sib npaug.
Tshawb xyuas nrog cov ntaub ntawv xa khoom: Thov kom paub meej Cov Ntaub Ntawv Cov Ntaub Ntawv (MDS) thiab EN 10204 Hom 3.1 zeb xeem daim ntawv qhia los ntawm cov chaw muag khoom, uas yuav tsum tau qhia meej txog cov khoom xa tuaj, cov khoom siv sib xws (lub zog, elongation, cuam tshuam lub zog), thiab qib zoo.
Zam kev tsis meej pem: Yog tias tus neeg muag khoom tsis tuaj yeem lees paub qhov kev xa khoom lossis muab cov ntaub ntawv xeem, xyuas seb "S335J0WP" puas yog typo (piv txwv li, npaj S355J0WP, tus qauv EN 10025-5 qib nrog cov ntsiab lus ntawm kev xa khoom meej).
Hauv cov ntsiab lus, cov xwm txheej ntawm kev xa khoom rau S335J0WP Corten Steel yog cov thermo- tshuab dov (TMR/P, feem ntau), kub- dov (HR, nqi- zoo), thiab normalized (N, siab ductility). Xaiv qhov xwm txheej yog nyob ntawm qhov kev xav tau ntawm kev ua haujlwm, kev ua haujlwm nyuaj, thiab tus nqi. Qhia meej txog kev xa khoom nrog cov neeg xa khoom thiab tshawb xyuas los ntawm cov ntaub ntawv raug cai yog cov kauj ruam tseem ceeb los xyuas kom meej cov khoom tsim nyog.
