Cold Rolled Steel Sib sib zog nqus kos daim ntawv hlau DC01 DC03 DC04 DC05 DC06 DC07

Txias- dov ca steel khoom ua si lub luag haujlwm tseem ceeb hauv kev lag luam niaj hnub tsim, tshwj xeeb tshaj yog nyob rau hauv kev ua kom txias. Yuav kom ntseeg tau qhov zoo thiab sib xws ntawm cov khoom no, cov qauv tshwj xeeb yog qhov tseem ceeb heev. Cov qauv DIN EN 10130 thiab DIN EN 10152 txhais cov kev cai rau cov khoom no thiab muab lub hauv paus rau kev tsim thiab siv.

DC01 - Qib no tuaj yeem siv rau kev ua haujlwm yooj yim, xws li khoov, embossing, hlaws thiab kos duab.
DC03 - Qib no tsim nyog rau kev tsim cov kev xav tau xws li kos duab sib sib zog nqus thiab nyuaj profileing.
DC04 - Qib no yog tsim nyog rau kev tsim kom muaj siab.
DC05 - Qhov sib sib zog nqus- qib kos duab no yog tsim nyog rau kev tsim cov ntawv ntau dua.
DC06 - Qhov tshwj xeeb sib sib zog nqus- qib kos duab no yog tsim nyog rau kev tsim ntau tshaj plaws.
DC07 - Qhov no super tob- qib kos duab yog tsim nyog rau cov kev xav tau loj heev.

• TS EN 10130

DIN EN 10130 tus qauv qhia txog cov txheej txheem kev xa khoom rau cov khoom txias - dov ca ua los ntawm cov hlau tsis zoo uas yog tsim los rau cov txheej txheem txias txias.

• Cov xwm txheej kev xa khoom

DIN EN 10130 piav qhia meej txog cov txheej txheem kev xa khoom rau cov khoom txias - dov ca. Cov no suav nrog cov tshuaj muaj pes tsawg leeg, cov khoom siv kho tshuab thiab qhov zoo ntawm cov khoom. Ua raws li cov xwm txheej no ua kom cov khoom ua tau raws li qhov xav tau thiab cov lus qhia tshwj xeeb.

• Tshuaj muaj pes tsawg leeg

Cov tshuaj muaj pes tsawg leeg yog qhov txiav txim siab rau cov khoom ntawm cov hlau. Raws li DIN EN 10130, cov ntsiab lus carbon rau cov hlau zoo xws li DC01 yuav tsum tsis pub tshaj 0.12%. Tsis tas li ntawd, cov ntsiab lus ntawm manganese thiab phosphorus yog nruj me ntsis tswj. Qhov muaj pes tsawg leeg no ua kom lub siab txias formability thiab qhov zoo tshaj plaws saum npoo zoo.

• Mechanical zog

Cov khoom siv kho tshuab ntawm cov khoom tsim ua raws li DIN EN 10130 tau ua kom zoo rau cov txheej txheem txias txias. DC01, piv txwv li, muaj lub zog tensile yam tsawg kawg nkaus ntawm 270-410 MPa thiab qhov tsawg kawg nkaus elongation ntawm 28%. Cov khoom no tso cai rau cov khoom siv ua haujlwm zoo yam tsis muaj kev tawg lossis tawg.

• Hom nto

Qhov saum npoo zoo ntawm cov khoom txias- dov ca yog lwm qhov tseem ceeb ntawm DIN EN 10130. Tus qauv txhais tau ntau yam kev ua tiav, xws li du lossis matt, kom ua tau raws li cov kev cai tshwj xeeb ntawm cov ntawv thov kawg. Qhov zoo ntawm qhov chaw zoo yog qhov tseem ceeb rau cov txheej txheem txheej txheej tom ntej lossis cov ntawv siv kho kom zoo nkauj.

Nto hom A
Qhov tsis xws luag xws li pores, me grooves, me me warts, me ntsis khawb thiab me ntsis discoloration uas tsis cuam tshuam qhov haum rau kev tsim thiab adhesion ntawm nto coatings yog tso cai.

Nto hom B
Qhov zoo dua yuav tsum tsis muaj qhov tsis xws luag rau qhov zoo li qhov tsis zoo ntawm cov txheej txheej zoo lossis cov txheej txheem electrolytically tsis muaj kev cuam tshuam. Lwm sab yuav tsum tsawg kawg ua tau raws li qhov yuav tsum tau ua rau saum npoo hom A.
