1.What yog cov tshuaj lom neeg muaj pes tsawg leeg ntawm DC07?
Cov pa roj carbon (c): tsawg dua lossis sib npaug rau 0.01%. Qhov no feem ntau cov ntsiab lus carbon muaj zog tshaj plaws muab kev ua siab loj thiab cov qauv zoo.
Manganese (MN): tsawg dua lossis sib npaug rau 0.25%. Qhov no yuav pab txhim kho lub zog thiab qhov nyuaj ntawm cov hlau.
Phosphorus (p): tsawg dua lossis sib npaug rau 0.020%. Cov ntsiab lus phosphorus ntau dhau lawm tuaj yeem txo cov plasticity thiab kev nruj ntawm cov hlau. DC07 nruj me ntsis tswj cov ntsiab lus no kom txo qis cov kev tsis zoo no.
Sulphur (s): tsawg dua los yog sib npaug rau 0.020%. Sulphur tuaj yeem ua rau kub brittleness hauv cov hlau. Cov ntsiab lus Sulfur Sulfur tsis muaj txiaj ntsig ua kom zoo rau cov hlau zoo.
Titanium (ti): tsawg dua los yog sib npaug rau 0.20%. Cov ntsiab lus no ua kom cov noob qoob loo thiab txhim kho cov plastonity thiab tawv ntawm cov hlau.
Aluminium (Al): Ntau dua lossis sib npaug rau 0.015%. Aluminium ua raws li deoxidizer hauv cov hlau, pab txhim kho nws cov qauv thiab cov khoom.
2.How yog qhov ua tau los ntawm DC07?
Kev sib sib zog nqus - Kev Qho: tuaj yeem kos rau hauv cylindrical seem (tob}), xws li tua hluav taws tsev thiab lub cev muaj zog.
Flanging: Tsis kam tawg thaum khoov cov npoo (xws li lub taub hau ntawm lub qhov rooj tsheb).
BULGUND: Tsim Bulges los ntawm kev ncab kev ncab (xws li lub tsheb headlight npog).
3.Yog li cas yog qhov chaw zoo ntawm DC07?
Qhov saum npoo roughness tom qab dov txias yog ra tsawg dua lossis sib npaug rau cov txheej txheem ncaj qha lossis cov electroplating (galvanized version yog tsim dc07+ z).
Nws yog pub dawb ntawm nplai tsis xws luag, ua kom lub loog ntawm cov khoom siv sab nraud hauv tsev (xws li lub tub yees qhov rooj (xws li cov qhov rooj tub yees txias).
4.What yog tus kws kos txuj ci thiab cov ntaub ntawv xaiv cov lus pom zoo rau DC07?
Ua ntej - stamping kev kho:
Lubrication yuav tsum tau (thov 1-3 g / m²) los txo kev tuag txhuam.
Vuam sib xyaw:
Tsawg -} cov ntsiab lus carbon monoxide yog tsim nyog rau chaw vuam thiab laser vuam, tab sis tshav kub yuav tsum tau tswj kom tsis txhob graining.
Lwm Yam Khoom:
Higher requirements: Choose DC06 (r-value>=2.3, ultra-deep drawing grade).
Rau kev nce zog: xaiv H220yd + Z (Galvanized siab {}} Lub zog hlau, muab ob qho tib si xeb ua haujlwm thiab thauj ob qho tib si.
5.Qhov dab tsi yog cov yam ntxwv ua kom zoo ntawm DC07?
Zoo heev: elongation ntau dua los yog sib npaug ntawm 44%, tswj cov kev tsim khoom zoo thiab ncab tsim kev ua haujlwm, thiab siv tau los tsim cov kev ua haujlwm ntawm- zoo qhov chaw.
Zoo heev weldability: tsawg cov ntsiab lus carbon: tsawg cov ntsiab lus tsis tshua muaj kev phom sij
Zoo heev nto zoo: Heev du nto ua rau nws yooj yim rau lub tsho loj thiab phaj, ua kom muaj xeb tsis kam.
Lub zog ruaj khov: tensile zog feem ntau yog li ntawm 250 mpa, tawm lub zog los ntawm 100-150 mpa, thiab hardness los ntawm 60-90 hrb. Qhov zoo tshaj plaws tag nrho cov khoom siv tshuab ua kom nws ua tau raws li cov cai ntawm kev ua haujlwm ntau yam.
