Qauv Txheej txheem cej luam
1.} EN10025 yog tus qauv rau kev tsim cov qauv steel thiab yog qhov tseeb} Tus qauv steel hlau thiab yog dav siv hauv kev tsim kho, txuas hniav, kev tsim khoom siv machinery, tshuab ua haujlwm, nkoj thiab lwm yam kev lag luam .
2.}} kev siv tshuaj lom neeg muaj pes tsawg leeg
Muaj cov cai nruj rau cov tshuaj lom neeg ntawm cov hlau, tshwj xeeb tshaj yog cov kab mob hlau (mnc), si), sidicon (xws li S235, S275, et1 {{{5 5}}) muaj qhov sib txawv ntawm cov khoom siv tshuaj lom neeg thiab cov khoom siv corrosion ntawm cov hlau {}}
{{03. cov khoom siv mecharical
Cov kev cai qhia ntxaws yog ua rau cov cuab yeej siv tshuab ntawm cov hlau, ua kom muaj zog, ua kom muaj zog, cuam tshuam rau cov khoom siv sib txawv hauv cov khoom siv sib txawv, piv txwv li:
S235 steel: tensile muaj zog yog 360 - 510 mpa mpa mpa, lub zog (tsawg kawg tus nqi).
S275 steel: tensile muaj zog yog {}} mpa}} Tus nqi tsis tshua muaj nyob ntawm qib ntawm cov hlau1.
{{04. qhov ntev thiab kev ua kom muaj nuj nqis
Qhov ntev thiab kev ua tsaug ntawm cov hlau tau hais meej los xyuas kom meej qhov tseeb thiab cov khoom siv tuab tuaj yeem sib txawv, cov khoom siv kub sib txawv, nyob ntawm 400 hli, nyob ntawm qib thiab siv cov hlau; Qhov dav ntawm kub-rolled sawb hlau feem ntau yog 1000mm txog 2500mm, nyob ntawm qhov kev teeb meem; Qhov ntev ntev ntawm cov hlau sib txawv raws li cov qib sib txawv cov qib, thiab kev pabcuam dav dav dav dav yog ± 5mm.
5. Kev Kho Mob Kub Kub
Cov kev xav tau yog tsim rau txheej txheem kho cua sov, tshwj xeeb yog tsim los kho nws cov txheej txheem S355 thiab saum toj no, uas tuaj yeem txhim kho nws lub zog thiab lub zog; annealing feem ntau yog siv rau cov phiaj hlau thicker los pab tshem tawm sab hauv kev ntxhov siab thiab txhim kho lub tshuab luam ntawv ntawm cov hlau {}}
6. npoo zoo thiab kho tsis xws luag
Cov yam yuav tsum ua nruj yog raug tsim tawm ntawm qhov chaw zoo ntawm cov hlau:
Oxide Nplai: Yuav tsum tsis muaj Oxide nplai lossis cov khoom paug yuav cuam tshuam rau kev ua yeeb yam vuam thiab corrosion tsis kam .
Cov kab nrib pleb thiab cov quav: cov nplaim hluavtaws yuav tsum tau muaj qhov tawg, quav lossis lwm yam tsis xws luag, uas yuav zoo dua txo lub zog thiab durability ntawm steel .
Cov npoo av tiaj tiaj: Yuav tsum khaws cia hlau yuav tsum khaws cia kom tsis txhob muaj teeb meem uas tsis muaj teeb meem vim yog cov khoom ua tsis ncaj vim yog {}}
Vuam Txoj Kev Ua Tau Zoo
Rau cov hlau uas yuav tsum tau welded, cov hlau yuav tsum tau weldred lub vuam ua raws li qhov kub thiab kev kub siab ib puag ncig tsis muaj kev tawg lossis lwm yam tsis xws luag .
