Qib DC07 yog dab tsi?
Qib DC07 nthuav tawm qhov sib sib zog nqus zoo heev - kos peev xwm nyob rau hauv txhua hom deformation. Qhov no super sib sib zog nqus nqus qib yog tsim rau cov kev xav tau loj heev thiab yog ib qho ntawm cov siab -zoo, qis-carbon Ti alloy IF steels. DC07 yog li tshwj xeeb tshaj yog haum rau kev sib sib zog nqus tob- kos duab thiab ncab- ua ntu xws li sab phab ntsa, roj lauj kaub thiab cov phaj hauv qab.
Txias-rolled steel yog ib yam khoom uas tau txias txo, as opposed to kub-rolled, nyob rau hauv thiaj li yuav impart tej yam khoom, deg tiav, gauge kam rau ua thiab strip puab. Cov txiaj ntsig ntawm cov ntawv txias -rolled ntawv yog qhov ua tau zoo hauv kev ua haujlwm uas yuav tsum tau kos duab sib sib zog nqus thiab sib sib zog nqus bending thiab sib sau.
Txias- dov yog yooj yim rau welding thiab kev npaj ntawm nws cov khaubncaws sab nraud povtseg rau daim ntawv thov ntawm finishes yog yooj yim thiab pheej yig. High-lub zog, txias- dov cov ntawv hlau yog siv los txo qhov hnyav thaum ua kom muaj zog thiab kav ntev uas tuaj yeem ua rau txo nqi rau cov neeg siv khoom.

1) Yog tias tsis muaj lub zog tawm los yog txhais tau, cov txiaj ntsig zoo yuav tsum siv rau 0.2% pov thawj kev ntxhov siab (Rp0.2) lossis qis dua lub zog (ReL). Rau cov thicknesses tsawg dua los yog sib npaug li 0.7 hli tab sis> 0.5 hli, qhov siab tshaj tawm lub zog qhov tseem ceeb yuav yog 20 MPa siab dua. Nyob rau hauv cov ntaub ntawv ntawm thicknesses tsawg tshaj li los yog sib npaug zos rau 0.5 hli, qhov siab tshaj tawm los txwv tej zaum yuav 40 MPa siab dua.
2) Rau thicknesses tsawg dua los yog sib npaug rau 0.7 hli tab sis> 0.5 hli, qhov tsawg kawg nkaus elongation ntawm pob txha yuav yog 2 units qis dua. Rau thicknesses Tsawg dua los yog sib npaug rau 0.5 hli, qhov tsawg kawg nkaus elongation ntawm pob txha yuav yog 4 units qis dua.
3) r90 thiab n90 qhov tseem ceeb siv rau cov khoom thicknesses Ntau dua lossis sib npaug li 0.5 hli nkaus xwb.
4) Rau thicknesses> 2 hli, r90-tus nqi raug txo los ntawm 0.2.
FAQ
1. Qhov txawv ntawm DC07 thiab DC01, DC03, DC04, DC05, thiab DC06 yog dab tsi?
Lub ntsiab sib txawv ntawm cov qib no yog nyob rau hauv lawv formability. DC01 yog tsim rau kev ua haujlwm yooj yim; Raws li qib qib nce, cov kev tsim thiab kev muaj peev xwm kuj nce ntxiv, nrog rau DC07 yog qhov ultra-cov qib kos duab sib sib zog nqus hlau nrog lub zog tshaj plaws formability.
2. Cov tshuaj muaj pes tsawg leeg ntawm DC07 yog dab tsi?
DC07 yog ib qho qis -carbon titanium alloy IF steel (interstitial-dawb steel). Nws cov tshuaj muaj pes tsawg leeg (xws li, qhov siab tshaj plaws feem pua ntawm cov pa roj carbon, manganese, silicon, phosphorus, thiab sulfur) ua raws li cov qauv tsim xws li EN 10130.
3. Dab tsi yog cov khoom siv kho tshuab ntawm DC07?
Cov khoom siv kho tshuab ntawm DC07 feem ntau suav nrog: tensile lub zog ntawm kwv yees li 250 - 310 MPa, tawm lub zog ntawm kwv yees li 100 - 150 MPa, thiab elongation ntawm kev tawg feem ntau ntau dua lossis sib npaug li 44% (nyob ntawm qhov tuab).
4. Puas yuav DC07 steel daim hlau xeb?
Yog lawm, lawv yuav xeb. DC07 yog carbon hlau, uas nws lub ntsiab yog hlau, thiab nws yuav oxidize nyob rau hauv cov huab cua ntub los ua xeb. Kev kho deg (xws li galvanizing, oiling, lossis pleev xim) yog xav tau rau kev tiv thaiv corrosion.
