DC06 Cov Khoom Siv Neeg Kho Tshuab

DC06 Cov Khoom Siv Neeg Kho Tshuab
Raws li lub siab - cov ntawv txias txias (Raws li cov khoom siv hlau sib sib zog nqus (ua haujlwm siab heev (siab elongation). Qhov no ua rau nws haum rau kev sib sib zog nqus duab, kev sib tw, thiab lwm yam kev ua rau cov ntu. Cov hauv qab no muab cov ncauj lus kom ntxaws tshuaj xyuas ntawm nws cov khoom siv ntawm plaub qhov kev xav: cov qauv ntsuas, kev ua tau zoo, thiab thov kom haum:
1. Cov ntsuas kev ua haujlwm txhua yam ua tau zoo (ua raws li EN 10130)
DC06 cov khoom siv tshuab cov tshuab raug sim los ntawm kev kuaj ntshav Tensile. Tus qauv cim qhia txog cov cai muaj zog, thiab elongation muaj zog raws li qhov tuab me me (thicker tuab tuab me ntsis thiab me ntsis qis elongation). Hauv qab no yog cov qauv tseem ceeb thiab cov nqi sib tw uas nquag muaj rau cov tuab tuab (0.5-2.0 hli):
Cov Cuab Yeej Siv Cov Neeg Kho Tshuab Chav Tsev Yuav Tsum Tau Ua (EN 10130) cov txiaj ntsig ntau lawm
Yield Strength (Rp0.2) MPa<=140 110-135 Extremely low yield strength reduces forming resistance and prevents part cracking.
Tensile Lub Zog (RM) Mpa270-350 280-340 Balances muaj zog thiab cov yees siv kom ntseeg tau tias muaj kev sib sau tom qab sib sau.
Elongation thaum so (A80mm)% ntau dua lossis sib npaug nrog38 40-45 siab} Cov khoom muaj peev xwm txaus cuam tshuam rau kev kos duab kom sib sib sib zog nqus.
Yas strain piv (r {- tus nqi)-}} 2}}}} 2.0 (ntau dua qhov muaj nuj nqis sib sib zog ua kom tiv taus ntau dua).
Lim hardening exponent (n {{- tus nqi)-}} l} 0.28 yog cov khoom tsis muaj txiaj ntsig. Qhov siab dua N tus nqi n tus nqi, ntau dua qhov tsis zoo uas muaj peev xwm deformation thiab tsawg zaus hauv zos thinning.
Ii. Cov yam ntxwv ua kev ua tau zoo thiab qhov tseem ceeb engineering
DC06 cov khoom siv tshuab tau tsim los ntawm cov cai ntawm cov kev cai sib sib nqus. Cov yam ntxwv ntawm txhua qhov ntsuas ncaj qha txiav txim siab nws cov khoom lag luam uas haum:
1. Tsis tshua muaj txiaj ntsig tsawg zog zog (RP0.2 tsawg dua lossis sib npaug ntawm 140MPA)
Nta: Qhov no yog qis dua li hais tias ntawm dist disty cold {{rolled steel tsawg dua los yog sib npaug ntawm 280mpa), ua rau "muag muag nyuaj".
Engineering Tseem Ceeb: Kev teeb duab qis dua thiab kev sib tw busces yog qhov yuav tsum tau thaum lub sij hawm ua, txo kev tuag hnav thiab cov cuab yeej thauj khoom. Qhov no kuj zam kev tawg lossis pob hauv ntu tshwm sim los ntawm kev ntxhov siab hauv ib cheeb tsam.
2. High elongation (a80mm ntau dua los yog sib npaug rau 38%)
Nta: Qhov no elongation yog 1.5- 2 zaug uas muaj cov txheej txheem zoo tib yam (piv txwv li yog kwv yees li 21%), ua rau muaj peev xwm deformation siab. Engineering Qhov tseem ceeb: Cov ntaub ntawv tuaj yeem tiv taus cov kev sib nqus tseem ceeb (piv txwv li cov txheej txheem sib sib zog nqus dej (piv txwv li, cov tshuab roj carrobile thiab tshuab nqus tsheb tshuab).
3. Zoo r thiab n qhov tseem ceeb (Qaum sib sib zog nqus teeb meem)
Yas Strain Piv (R tus nqi): Refease cov ntaub ntawv "Planar anisotropy" (r {} transverse hlab / tuab quav).
DC06's R tus nqi ntau dua los yog sib npaug rau 2.0 txhais tau tias thaum nqus tau ntau dua li cov ntawv nyias nyias los ntawm cov ntawv nyias nyias, xws li cov khoom siv nyias nyias los ntawm cov hauv qab los yog cov khoom siv sib sib zog nqus (piv txwv li, fillets ntawm cov vaj huam sib luag ntawm cov vaj tse hauv automorive).
Lim hardening exponent (n tus nqi): tsom kwm cov khoom siv "cov kev sib txawv ntawm cov khoom muaj peev xwm." Qhov siab dua N tus nqi n tus nqi, ntau dua cov khoom siv yog "uniformly harden" nyob rau hauv kev ntxhov siab, tsis yog undergoing unformation. DC06's N tus nqi ntau dua los yog sib npaug ntawm 0.22 txo qis "thining hauv zos" (ua kom ntxov dua nyob rau hauv ib thaj chaw tshwj xeeb) thaum lub sijhawm nqus phaj, kom muaj kev sib sib zog nqus tuab thoob plaws ib feem.
4. Tsis muaj Xil toj siab (tom qab npau taws dov)
Nta: Pa Annealed hlau nthuav qhia "los ua ke nrog kev ntxhov siab tas li), ua rau" lüders kab "(saum streaking tsis xws luag) thaum lub sij hawm sib sau. Tom qab kev npau taws (txo cov piv
Engineering Qhov tseem ceeb: Qhov no tshem tawm saum npoo deg xws li surneaks thiab dents ntawm cov ntaub ntawv sib sib zog nqus (xws li qhov ntsuas hluav taws xob sib sib zog nqus) lossis xav tau qhov siab txuas rau sab nrauv. III. Yam cuam tshuam kev ua tau zoo (kev sib raug zoo rau cov txheej txheem ntau lawm)
DC06's cov khoom siv mechanories tsis innate; Es, lawv tau ua tiav los ntawm kev tswj kom meej thoob plaws hauv tag nrho cov txheej txheem. Cov ntsiab lus tseem ceeb yog raws li hauv qab no:
Kev tswj kom muaj pes tsawg leeg: Ultra - Cov pa roj hmab qis (C tsawg dua li 0.015%) txo lub carbide nag lossis kom muaj zog;
Nruam Kev Ua Lag Luam: 750-800 DIBREED tso cai rau ua tiav cov recrystallization, tsim cov khaub ncaws hnav zoo (15-25μm), txhim kho elongation thiab R / N piv;
Qhov Kub Dov: Tshem Tawm Cov Sawv Daws Toj Siab thiab Finely Hloov Cov To Hardness (kom ua rau cov ntu tiv thaiv tom qab kev sib sau). IV. Daim Ntawv Thov Kev Ua Si thiab Kev Ua Tau Zoo
DC06's Cov Khoom Siv Cov Neeg Kho Tshuab Dictures Nws thawj daim ntawv thov rau cov kev sib tw siab tob tob tob tob {1} {kos cov chaw. Cov ntawv thov raug muaj xws li:
Kev lag luam roj tsheb: roj tso tsheb hlau luam, ntsuas cov kab vaj huam sib luag, thiab lub qhov rooj sab hauv thiab cov thickness sib sib sib zog nqus);
Kev lag luam hauv tsev Kev Lag Luam: Tshuab ntxhua khaub ncaws nruas, cua txias compressor tsev, thiab cov tub yees teb evapation (xav tau cov elongation siab thiab tawg tawm);
Cov chaw ua kom zoo: Cov tsev kho mob thiab cov thawv ntim tshuab thiab cov hlau tsis muaj tshuaj pleev ib ce thiab cov qauv ua kom zoo).
Hauv cov ntsiab lus, cov kws ua haujlwm tseem ceeb ntawm kev ua ke ntawm "Qis zog ntawm" lub zog qis, kev ua haujlwm siab, thiab zoo heev. " Los ntawm kev tswj kom ncaj ntawm cov txiaj ntsig los ntawm lub zog, elongation, thiab r / n piv, nws tau dhau los ua cov khoom ntawm kev xaiv rau cov khoom sib sib zog nqus. Nws cov kev ua tau zoo yog nyob ntawm cov txheej txheem ruaj khov thoob plaws lub statmaking, dov, thiab annealing cov txheej txheem.
