Q550nhure yaam hlau tuaj yeem tawg thaum khoov yog tias siv tau, tab sis muaj kev pheej hmoo tswj tau nrog kev coj ua. Ntawm no yog phau ntawv qhia luv luv kom tiv thaiv kev tawg:
1. Qhov tseem ceeb txaus ntshai rau kev tawg
Siab Zog: Tawm lub zog loj dua los yog sib npaug rau 550 MPA nce siab tawv versus me hlau.
QUILITY: Elongation (ntau dua lossis sib npaug rau 17%) yog qis dua cov hlau hlau, xav kom ceev faj hom plaw kev tswj hwm.
Qhov tuab: Plates >12 hli muaj ntau dua rau ntug kev tawg.
2. Dab neeg kev coj ua zoo tshaj plaws
Dabtsi yog khoov khoov (chav kub)
Tsawg kawg nkaus khoov vojvoog: Loj dua los yog sib npaug rau 2 × Cov Khoom Thooj thickness (piv txwv, 24 hli rwb rau 12 mm phaj).
Preheating (yog xav tau): 100–150°C for thick sections (>20 hli) lossis nruj nreem.
Khoov kev taw qhia: Dlisp nrog cov kev taw qhia yob kom txo cov kev cuam tshuam anisotropy.
Dabtsi yog khoov (rau cov duab nyuaj)
Qhov ntsuas kub ntau: 850-950℃(zam dhau 1,100℃los tiv thaiv cov noob qoob loo).
KUB CUA TXIAS: CUA {- txias rau chav kub; Zam kev tso dej quenching.
3. Kev tiv thaiv tseem ceeb
Lub tuam txhab: Siv cov ntse, polished tuag kom tsis txhob muaj saum npoo xis (kev ntxhov siab cov kev xav).
Tshaj tawm - bend soj ntsuam: Txheeb xyuas cov microcacks ntawm cov xim nkag mus kuaj (PT) ntawm ntu tseem ceeb.
Zam dhau -} khoov: Tshaj cov khoom siv elongation txwv ua rau pob txha.
4. Khoom npaj npaj
Li Qub: Xav li ib txwm q550nh dhau ntawm -}} rolled rau kev ntaus nqi zoo dua.
Ntug zoo: Debur thiab kev txiav kev txiav du ua ntej khoov.
5. Thaum tawg tau tshwm sim
Me sib tsoo: Grind tawm thiab sib tov zoo.
Cov txheej txheem qauv: Tsis lees txais ntu; Tsis txhob weld -}}} kho tsis muaj kev ntxhov siab.
