Qauv Txheej txheem cej luam
En 10025-3 yog ib feem ntawm cov qauv siv hlau kub siv rau qhov qub \/ siv cov qauv vaj tsev zoo sib xws. Cov qauv no tau pom zoo los ntawm European Committee rau cov qauv (CEN) rau lub Plaub Hlis 1, 2004, hloov en {6}}: 1993.
1. Tsw
Siv tau rau ib txwm \/ no rolled weldable nplua-grained cov qauv txheej txheem hlau, thiab yog siv rau welded, bolted thiab riveted steel qauv ntawm huab cua sov.
2. Cov Qauv Ntawv
Cov qauv qauv: muaj cov qauv lossis tsis pub dhau los ntawm lwm cov ntawv tshaj tawm, thiab kev hloov kho nyob rau hnub, thiab kho dua tshiab tsis siv rau tus qauv no.
Qhov loj me thiab thev muaj cov qauv: muaj cov kev cai cuam tshuam hauv cov kab lus tshwj xeeb (xws li 7.7.1).
Cov Qauv Tshuaj Xyuas: Muaj cov qauv tshuaj xyuas cov qauv.
3. Cov lus thiab cov ntsiab lus txhais
Normever dov: Muaj lub ntsiab lus meej ntawm cov txheej txheem no.
Cov hlau nplej zom hlau: lub ntsiab lus ntawm cov nplej cov qoob loo hlau tau muab.
4. Kev faib tawm thiab lub npe
Kev sib faib
Cov pawg tseem ceeb: Muaj ib qho kev faib tawm ntawm cov khoom tseem ceeb.
Hom thiab qhov zoo: muaj cov ncauj lus kom ntxaws qhia txog ntawm hom thiab qhov zoo ntawm cov hlau.
Lub npe
Lub npe yuav tsum ua raws li en 10025-1.
Qhov muaj pes tsawg leeg ntawm lub npe tau teev tseg, thiab cov npe ntawm cov khoom lag luam yuav tsum ua raws li cov cim qhia, kom muaj lub cim tshwj xeeb thaum cov khoom lag luam tshwj xeeb hauv lub xeev (xws li + n lossis + ar).
5. Xav tau
Txheej txheem cej luam: Kev qhia dav dav ntawm cov kev xav tau rau hom hlau no.
Tshuaj lom neeg tshuaj lom neeg: muaj cov cai nruj ntawm cov tshuaj lom neeg muaj pes tsawg leeg.
Cov Khoom Siv Neeg Kho Tshuab
Txheej txheem cej luam: Kev qhia dav dav ntawm cov cai rau cov khoom siv kho tshuab.
Cov yam ntxwv cuam tshuam: Qhov yuav tsum muaj rau kev cuam tshuam kev nqus hluav taws xob kuaj hauv qhov chaw kub tsawg tsawg yog teev. Piv txwv li, S275NL xav tau kev cuam tshuam kev nqus hluav taws xob kev kuaj mob hauv qhov chaw tsawg 50 degrees tsis tsawg dua 27J.
Cov yam ntxwv hloov kho cov khoom ntawm cov khoom lag luam tawm ntawm cov khoom lag luam: Muaj kev sib tw yuav tsum tau rau cov hlau nrog cov yam ntxwv no.
Yam ntxwv
Weldability: Nrog rau nce cov khoom tuab thiab muaj zog, nws yog ib qho tsim nyog los txiav txim siab txias rau hauv held-cuam tshuam txog kev sib cais kub ntawm Weld sib koom tes. Nyob rau tib lub sijhawm, muaj qee yam kev xav tau rau lub weldability ntawm cov hlau.
DeFormancion: Muaj cov kev cai tshwj xeeb ntawm deformation kev ua tau zoo ntawm cov hlau.
Haum rau kub-dip Galvanized Sheet: Qhov kev ua kom haum rau cov hlau rau cov txheej txheem kub-dip.
Cov yam ntxwv saum npoo: sib txawv ntawm cov khoom steel xws li cov hlau strip muaj cov sib txawv yuav tsum muaj rau cov chaw saum npoo. Piv txwv li, yog tias tus txheej txheem sawb yog kho kom zoo, cov xwm txheej saum npoo yuav tsum tsis muaj zog ntawm cov hlau, thiab lwm yam.
