Dab tsi yog qhov tseem ceeb ntawm DC06 steel phaj?
A: DC06 yog ib qho ultra- kos duab sib sib zog nqus qib txias- dov qis- cov pa roj carbon steel, uas yog cov khoom siab tshaj -kawg ntawm cov khoom txias- dov steel phaj. Nws cov txiaj ntsig tseem ceeb yog ductility siab, zoo heev formability, thiab siab saum npoo zoo, tshwj xeeb yog tsim rau kev sib sib zog nqus nqus ntawm complex- zoo li qhov chaw.
Dab tsi yog cov cim tseem ceeb ntawm DC06 qhov kev ua tau zoo "ultra-" tob tob?
A: Cov ntsiab lus tseem ceeb suav nrog: yield zog 100-180MPa, lub zog tensile Ntau dua lossis sib npaug rau 250MPa (qee cov qauv 270-370MPa), elongation tom qab tawg ntau dua los yog sib npaug rau 39%-42% (nce nrog thickness), yas strain ratio r Zoo dua los yog sib npaug rau 2. 0.22. Cov ntsuas no xyuas kom meej tias nws tuaj yeem tiv taus qhov loj tensile deformation yam tsis muaj tawg.
Dab tsi yog cov yam ntxwv ntawm DC06 cov tshuaj muaj pes tsawg leeg?
A: Cov tub ntxhais yog "ultra-} qis carbon" tsim: carbon (C) Tsawg dua lossis sib npaug li 0.03% (siab-kawg tus qauv Tsawg dua lossis sib npaug li 0.006%), manganese (Mn) Tsawg dua lossis sib npaug li 0.30%, phosphorus (P) Tsawg dua lossis sib npaug rau 0.00% sulfur (S20%) aluminium (Al) Ntau dua tshaj los yog sib npaug rau 0.015% -0.020%, nrog qee qhov titanium (Ti) / niobium (Nb) Tsawg dua lossis sib npaug li 0.20% ( txhim kho cov qauv nplej). Tsis tshua muaj impurity cov ntsiab lus ua kom siab plasticity thiab corrosion kuj.
Dab tsi yog qhov txawv ntawm DC06 thiab DC01-DC05? A: Qhov sib txawv tseem ceeb nyob hauv qhov sib sib zog nqus- kos duab kev ua tau zoo thiab purity: DC06 yog ultra- sib sib zog nqus- qib kos duab (qib siab tshaj), nrog cov ntsiab lus qis tshaj plaws thiab qhov siab tshaj plaws elongation thiab r-tus nqi; DC01-DC04 yog cov qhab nia zoo tib yam / sib sib zog nqus kos duab, nrog kev ua kom muaj zog tab sis txo qis formability. DC06 yog qhov tsim nyog rau ntau qhov kev kos duab (xws li cov tsheb sab nrauv), thaum DC01-DC05 feem ntau yog siv rau qhov yooj yim khoov thiab stamping qhov chaw.
Dab tsi yog cov qib zoo ntawm DC06?
A: Muaj peb qib: ①FB (O3): Tso cai rau cov khawb me me thiab cov ntaub ntawv tsis cuam tshuam rau txheej txheem molding; ②FC (O4): Tsis muaj qhov tsis pom tseeb ntawm ib sab, thiab sab nraud ua tau raws li tus qauv FB; ③FD (O5): Tsis muaj qhov tsis xws luag ntawm ib sab (ua tau raws li kev kos duab / electroplating), thiab sab nraud ua tau raws li FB tus qauv. Qib O5 feem ntau yog siv rau tsheb sab nrauv lub cev panels.
