Qhov Kev Tsim Nyog Qib Tiag Tiag Qhia rau tus neeg yuav khoom
S460NH tawg ua peb daim ntaub ntawv uas txhua qhov cuam tshuam rau kev xa khoom sib txawv. CovStsuas yog qhia txog cov qauv hlau. Cov460yog qhov tsawg kawg nkaus yield zog nyob rau hauv MPa - qhov no yog tus naj npawb uas cia ib tug structural engineer qhia ib tug me me, sib zog seem tshaj ib tug sib npaug S355 tus tswv cuab thaum tseem nqa tib lub tsim load, uas yog tag nrho vim li cas ib tug buyer xaus mus nrhiav S460 nyob rau hauv thawj qhov chaw es tsis txhob defaulting mus rau qhov deb ntau stocked S355. CovNHyog qhov chaw muab khoom tau yooj yim dua los npaj ib puag ncig: N txhais tau tias cov hlau xa mus rau qhov qub lossis zoo li qub -rolling mob, thiab H txhais tau tias nws yog qib hollow seem raws li EN 10219 tshwj xeeb (tsis yog S460NL, uas muaj qhov cuam tshuam qis dua - ntsuas kub rau txias{{0} 10} EN 1021} kev pabcuam kub, sib npaug).
Qhov yuav tsum tau normalizing yog ib feem buyers feem ntau underestimate. Nws yog cov kauj ruam kho cua sov uas ua kom zoo dua cov qauv nplej ntawm qhov txias - ua ntu kom rov ua kom tawv tawv uas ua haujlwm txias yuav txo qis - thiab nws txhais tau tias tsis yog txhua lub zeb uas tsim cov qauv S355 hollow seem tau teeb tsa los tseem tsim S460NH, vim tias cov kauj ruam ua ntxiv thiab cov tshuaj tiv thaiv nruj dua tswj nws xav tau cov kab ntau lawm. Sourcing S460NH ua tiav pib nrog kev lees paub lub zeb tshwj xeeb tau ua haujlwm zoo li qub- qib kev tsim khoom, tsis yog thov cov qib ntawm PO thiab xav tias muaj qhov khoob -section tus neeg muag khoom tuaj yeem sau nws.
Yog vim li cas ib qhov project qhia S460 Hloov S355 txhua
Lub zog tawm los siab dua tsis tuaj yeem ua rau S460 qhov kev xaiv zoo dua - nws ua rau kev nkag siab tshwj xeeb thaum tus qauv tsim muaj kev ntxhov siab - tswj hwm tsis yog deflection - lossis buckling - tswj hwm. Hauv kev ntxhov siab-cov tswvcuab tswj hwm (luv- ntu ntu thauj khoom hnyav, cov tswvcuab nruj, qee qhov truss chords), ntau dua - cov ntaub ntawv tawm los cia tus kws tshaj lij qhia txog tus ntoo khaub lig me me -section rau tib lub thauj khoom, ncaj qha txo cov hlau tonnage thiab, ntawm cov qauv loj, lub hauv paus thiab kev sib txuas ntawm tus kheej qhov hnyav.{10} Nyob rau hauv ib tug deflection- tswj los yog slenderness - tswj cov tswv cuab (ntev unbraced compression cov tswv cuab, cov tswv cuab qhov kev pab cuam deflection tswj tus tsim es tsis muaj zog), qib siab yield feem ntau tsis pab ntau, vim hais tias nruj nyob ntawm seem geometry thiab elastic modulus - ob qho tib si ntawm {5 thiab qhov tseem ceeb unchanged} yield zog. Qhov no yog vim li cas S460NH nthuav tawm hnyav rau ntawm ntug dej hiav txwv platforms, cov qauv kev lag luam hnyav, thiab ntev -span choj trusses qhov twg qhov hnyav txo tau cov nqi sib xyaw, thiab tsis tshua muaj nyob rau hauv qis qis - nce lub tsev framing qhov twg S355 twb muaj ntau tshaj qhov txaus thiab feem ntau yooj yim rau qhov chaw.
Weldability thiab Fabrication Considerations ntawm S460
Siab dua - lub zog steel tsis yog "cov hlau qub, muaj zog dua" los ntawm kev tsim cov qauv tsim - carbon sib npaug (CE) ua qhov kev txiav txim siab tiag tiag ntawm S460 nyob rau hauv ib txoj kev nws feem ntau tsis yog ntawm S355. Cov pa roj carbon ntau dua yuav ua rau muaj kev pheej hmoo ntawm hydrogen-induced cracking nyob rau hauv lub tshav kub- cuam tshuam cheeb tsam thaum vuam, uas txhais tau hais tias qhov chaw los yog khw welding txheej txheem rau S460NH kev sib txuas feem ntau xav tau preheat, tswj interpass kub, thiab tsawg- hydrogen consumables tau teev meej meej {{5} fabricator yuav siv tsis tau 3 qhov yuav tsum tau ua. lawv cov txheej txheem vuam txheej txheem specification. Cov neeg yuav khoom yuav tsum paub meej tias daim ntawv pov thawj zeb tus nqi sib npaug ntawm cov pa roj carbon monoxide (tsis yog tsuas yog paub meej tias qib dhau) thiab dhau daim duab ntawd mus rau tus kws tsim cov khoom siv vuam ua ntej lub khw kos duab tiav, vim tias cov txheej txheem vuam tsim nyog yuav tsum tau ua kom haum rau qhov tshwj xeeb ntawm cov cua sov chemistry, tsis yog ib qho kev xav ntawm S460.
FAQ
Q: Puas yog S460NH muaj zog dua S355 los ntawm qhov piv ntawm 460 rau 355?
A: Tsis siv tau ncaj qha rau kev tsim qauv - qhov sib piv ntawm lub zog tsis tau txhais ib qho - rau - ib qho rau hauv ib qho kev faib ua feem me me, vim tias Eurocode tsim cov tshev nyiaj kuj suav nrog buckling, slenderness hauv zos, thiab kev sib txuas tsim, uas tsis suav nrog lub zog tawm los. Qhov loj me me tuaj yeem ua tiav nyob ntawm seb hom twg tsis ua haujlwm tswj hwm tus tswv cuab tshwj xeeb, uas yog kev suav cov txheej txheem engineering, tsis yog qhov piv txwv yooj yim.
Q: Cov S460NH thiab S355 puas tuaj yeem txuas rau ib leeg hauv tib lub qauv?
A: Yog, qhov no yog ib qho kev xyaum ua - piv txwv li, lub siab -load kem nyob rau hauv S460NH txuas mus rau qis dua -kev nyuaj siab bracing nyob rau hauv S355 - tab sis cov txheej txheem vuam yuav tsum tsim nyog rau siab dua -carbon- khoom sib npaug, thiab cov weldatch muab tub lim rau cov hlau me ntsis los yog strengthly xaiv ntau dua dua tus qis.
Q: Vim li cas EN 10219 qhia qhov ntsuas qhov ntsuas qhov tsawg kawg nkaus rau kev cuam tshuam toughness ntawm S460NH?
A: Txias-tsim hollow seem ua haujlwm- tawv ntawm cov ces kaum thaum lub sijhawm tsim, uas tuaj yeem txo qhov hnyav hauv zos piv rau lub ntsej muag tiaj tus, thiab siab dua - lub zog steels feem ntau yog ntau dua notch- rhiab dua cov qib qis. Qhov kev ntsuam xyuas qhov cuam tshuam ntawm -20℃paub meej tias cov khoom khaws cia muaj zog txaus tiv thaiv kev tawg ntawm qhov kub thiab txias, uas tseem ceeb dua li cov khoom muaj zog nce ntxiv.
Q: Puas yog S460NH tus nqi sib npaug ntau dua S355 ib tonne?
A: Tus nqi ib -tonne tus nqi yog tiag tiag tab sis feem ntau me dua li cov hlau muaj peev xwm - hnyav txuag ntawm qhov kev ntxhov siab tiag tiag-tsim qauv, uas yog cov ntaub ntawv nyiaj txiag rau kev qhia nws hauv thawj qhov chaw - tab sis tus hwm yog loj dua li qhov sib piv ntawm lub zog ib leeg xav, vim hais tias ntawm qhov ntxiv normalizing kauj ruam thiab qis ntau lawm ntim, tsis yog vim lub hauv paus chemistry ntau dua.
