Cov qauv siv nyob rau hauv ntau lub teb chaws los teeb tsa cov kev cai rau cov hlau txias - xws li EN 10130, EN 10268, EN 10209, ASTM A1008 / A1008M, DSTU 2834, GOST 16523, GOST 9045 thiab GOST 17066, thiab lwm yam. ntau yam, lawv daim ntawv thov (profiling, txias forming, enamelling, dav siv, thiab lwm yam), mechanical zog, nto zoo thiab lwm yam tsis.
Cov ntawv txias-dov raws li European qauv
Feem ntau ua raws li European qauv rau kev tsim khoom yog EN 10130, EN 10268 thiab EN 10209.
EN 10130 yog siv los ua cov pa roj carbon tsawgdc01 ua, DC03, DC04, DC05, DC06 thiab DC07 steel qib rau txias sib sau tsis muaj txheej nrog qhov dav yam tsawg kawg nkaus ntawm 600 hli thiab qhov tsawg kawg nkaus thickness ntawm 0.35 hli

Cold-rolled steel ntawvtsim nyob rau hauv raws li tus qauv no feem ntau muab cov tawv nqaij-dhau; Txawm li cas los xij, raws li kev pom zoo, cov khoom tuaj yeem muab tau yam tsis muaj daim tawv nqaij dov. Ib yam yog qhov tseeb ntawm oiling siv los tiv thaiv xeb. TS EN 10130 Cov kev cai rau qhov zoo ntawm qhov chaw (А, B) thiab kev ua tiav (gloss b, semi-gloss g, matte m, ntxhib r) nrog rau lwm yam tsis muaj cov ntawv txias txias. Kev lees txais qhov loj me thiab cov duab zoo yuav tsum ua raws li EN 10131.
EN 10268 hais txog cov khaub thuas dov ca steel nrog lub thickness ntawm 3 hli los yog tsawg dua thiab muaj zog yield zog haum rau txias txias. Cov ntaub ntawv siv tau siv rau cov qib txias-dov steel hauv qab no nrog cov tshuaj sib txawv thiab cov khoom siv tshuab:
- B - cov hlau kho cua sov (HC180B, HC220B, HC260B, HC300B), uas qhia tau tias muaj qee qhov kev nce qib hauv kev siv cov khoom siv zog tom qab lawv cov cua sov mus rau 170 ° C rau 20 feeb
- LA - low-alloyed / micro-alloyed steels (HC260LA, HC300LA, HC340LA, HC380LA, HC420LA, HC460LA, HC500LA), uas muaj ib los yog ob peb alloying ntsiab nyob rau hauv lawv muaj pes tsawg leeg, xws li niobium, vanadium los yog titanium, kom ua tau raws li qhov yuav tsum tau muaj. zog
- Y - inclusion-free steels (HC180Y, HC220Y, HC260Y), uas nws muaj pes tsawg leeg yog tswj los txhim kho cov yas deformation r thiab strain hardening n
- I - isotropic hlau (HC220I, HC260I, HC300I) nrog me me parameter rau yas deformation r
Cov ntawv tsuas yog muab los ntawm cov khoom siv tawv nqaij. Feem ntau, dov steel los oiled. Nyob rau hauv cov ntaub ntawv no, ib tug homogeneous txheej ntawm nruab nrab tsis qhuav huv si roj yog siv rau ob sab rau xeb tiv thaiv kom tsis txhob muaj corrosion nyob rau hauv peb lub hlis ntawm ib txwm packing, tsheb thauj mus los, tuav thiab cia. Cov roj yuav tsum tau muab tshem tawm los ntawm cov tshuaj alkaline lossis cov kuab tshuaj ntau. Cold-dov daim hlau yog muab nrog rau saum npoo zoo А lossis B raws li EN 10130, tshwj tsis yog rau LA steel, uas tsuas muaj А hom nto zoo. Cov ntawv txias-dov tuaj yeem siv ntxiv rau cov txheej txheem hlau los ntawm submerging cov khoom rau hauv da dej hlau, siv cov txheej txheem electrolytic deposition, thiab / los yog siv cov organic thiab lwm hom txheej. Yog tias yuav tsum tau txheej txheej, qhov no yuav tsum tau qhia hauv qhov kev thov lossis kev txiav txim. Qhov loj thiab cov duab kam rau ua rau cov khoom dov mus rau ib lub thickness ntawm 600 hli los yog ntau tshaj sib haum mus rau cov uas qhia nyob rau hauv EN 10131, thaum kam rau ua rau cov khoom dov mus rau ib tug tuab ntawm tsawg tshaj li 600 hli sib haum mus rau EN 10140.
EN 10209 yog siv los tsim los ntawm DC01EK, DC04EK, DC06EK, DC03ED, DC04ED thiab DC06ED steel qib rau vitreous enamelling ntawm dov hlau nrog qhov dav ntawm 600 mm lossis ntau dua thiab tuab ntawm 3 hli lossis tsawg dua. Tus qauv qhia txog cov kev cai tseem ceeb rau cov tshuaj muaj pes tsawg leeg, cov khoom siv kho tshuab, qhov zoo ntawm qhov chaw thiab cov qauv kev sim rau cov kuav los tiag plstes. Qhov loj thiab cov duab kam rau ua rau cov khaub thuas dov steel yog teev nyob rau hauv ЕN 10131.
