Cov pa roj carbon tsawg thiab impurity cov ntsiab lus hauv DC04 txias dov steel kauj yog qhov tseem ceeb rau nws qhov tshwj xeeb ductility. Cov qib tswj ntawm phosphorus thiab sulfur txo cov khoom brittleness, thaum ntxiv ntawm txhuas (Ntau tshaj los yog sib npaug rau 0.015%) ua raws li ib tug deoxidizer, refining lub grain qauv thiab txhim kho nto tiav. Cov khoom siv kho tshuab- tsis muaj zog tawm los, siab elongation, thiab lub zog tensile sib npaug- pab kom cov khoom siv los ua cov yas deformation hnyav yam tsis muaj qhov tawg, qhov tseem ceeb tshaj plaws rau tsheb sib sib zog nqus - cov txheej txheem kos duab. Tsis zoo li tus qauv txias dov steel coils, DC04 qhov siab r-tus nqi thiab n- tus nqi xyuas kom tsis txhob muaj qhov sib txawv ntawm cov geometry nyuaj, txo cov thinning thiab springback thaum stamping.
Automotive Applications ntawm DC04 Cold Rolled Steel Chev
Kev lag luam automotive cia siab rau DC04 txias dov steel coil rau kev tsim khoom ntau yam, los ntawm cov vaj huam sib luag sab nrauv mus rau qhov sib txawv sab hauv. Raws li kev ntseeg siab txias dov steel coil chaw tsim tshuaj paus, GNEE STEEL's DC04 cov khoom raug tsim los daws cov teeb meem tshwj xeeb ntawm kev tsim tsheb, qhov twg precision, sib xws, thiab kev ua haujlwm tsis yog - sib tham.
DC04 txias dov steel kauj yog cov khoom ntawm kev xaiv rau qhov tseem ceeb sab nrauv tsheb qhov chaw uas yuav tsum tau complex shaping thiab flawless nto zoo. Cov no suav nrog:
- Qhov rooj panels: Lub siab formability ntawm DC04 tso cai rau cov creation ntawm du, nkhaus qhov rooj panels nrog nruj radii, tshem tawm defects nto thiab xyuas kom meej haum.
- Hoods thiab lub hau npog: Cov khoom loj, cov khoom siv no xav tau qhov sib sib zog nqus- kos duab muaj peev xwm, thiab DC04 qhov kev elongation zoo tshaj plaws ua rau ib qho - kauj ruam tsim, txo cov sij hawm tsim khoom thiab cov nqi.
- Fenders thiab sab panels: Cov khoom siv tiv thaiv kom nyias nyias thaum lub sij hawm ncab ua kom cov tuab tuab zoo ib yam ntawm cov - nkhaus qhov chaw, tuav cov qauv kev ncaj ncees thiab kev zoo nkauj.
Sab hauv thiab Cov Qauv Txheej Txheem
Tshaj li cov vaj huam sib luag sab nrauv, DC04 txias dov steel coil yog siv dav rau sab hauv thiab cov khoom siv tsheb uas xav tau ob qho tib si formability thiab lub zog:
- Instrument vaj huam sib luag substrates: DC04 qhov tseeb qhov tseeb thiab kev tsim ua kom nws zoo tagnrho rau kev tsim cov txheej txheem, cov txheej txheem recessed ntawm cov ntsuas vaj huam sib luag, txhawb ntau yam khoom siv hluav taws xob.
- Lub rooj zaum ncej thiab brackets: Cov khoom siv lub zog tensile sib npaug muab qhov tsim nyog kev txhawb nqa, thaum nws cov formability tso cai rau kev tsim cov duab zoo nkauj bracket.
