Careburizing txhim kho kev nyuaj tag nrho ntawm DC06?
Carburizing tsis cuam tshuam ntau dua qhov nyuaj ntawm DC06. Nws cov nyhuv tawv yog feem ntau muaj nyob hauv txheej txheej saum npoo av, tawm hauv cov tub ntxhais hluas tawv tsis hloov. Qhov no yog vim muaj cov yam ntxwv ntawm tus txheej txheem carburizing thiab cov khoom siv ntawm DC06. Cov laj thawj tshwj xeeb yog raws li hauv qab no:
1. Lub hauv paus ntsiab lus thiab cov qauv ntawm carburizing
Kev kho mob carburizing yog cov txheej txheem kho cua sov kev kho mob uas nkag rau hauv cov txheej txheem DC06 ntawm cov ntsiab lus ntawm cov txheej txheem ntawm cov txheej txheem ntawm cov txheej txheem ntawm cov txheej txheem ntawm cov txheej txheem ntawm cov txheej txheem ntawm cov thawj ultrasonic), nce ntxiv}} Tom qab, quenching thiab qis-kub femer fement ferting freat
Txawm li cas los xij, carburizing muaj qhov tob tob (feem ntau 0.1 -}}}}}}} mm, nyob ntawm lub sijhawm kho thiab kub). Tshaj li no qhov tob, cov pa roj carbon cov ntsiab lus sai sai rau thawj theem pib cov khoom siv (tsawg dua lossis sib npaug nrog 0.008%). Yog li ntawd, cov nyhuv tawv me me tsuas yog txo qis txheej saum npoo av tsis pub dhau ob peb cov qauv tseem ceeb, thaum muaj kev hloov pauv ntawm lub hardness.
Ii. Hardness muab faib cov yam ntxwv ntawm DC06 Hlau Tom qab Carburizing
Noj ib tug 1.0mm tuab dc06 steel phaj ua piv txwv, lub zog hluav taws xob tom qab carburizing (0.2mm carburized txheej) yog raws li hauv qab no:
Txheej Txheej (0-0.2mm): Tom qab quenching, lub hardness mus txog 55-65 hrc (kwv yees li 530-700 hv), txhim kho kev txhim kho kev coj tawm;
Kev hloov txheej (0.2-0.3mm): cov ntsiab lus carbon: thiab lub hardness dauv kom sai rau 30-40 teev;
Core (>0.3mm): cov ntsiab lus carbon: tsawg dua li lossis sib npaug nrog 0.008%, tus qauv yog ferrite, thiab lub hardness tseem yog thawj lub xeev (50-70 HRB, kwv yees li 80-130 hv).
Raws li tuaj yeem pom, tom qab carburizing dc06, tsuas yog tawv tawv, thaum lub siab tsis zoo (tshwj xeeb tshaj yog cov tsis hloov pauv, ua rau "nyuaj, cov me nyuam mos" mob.
III. Cov Tub Ntxhais Ua Vim Li Ua Tsis Tau Txhim Kho Kom Yooj Yim Ntau
Txwv ntawm tus txheej txheem carburizing:
Cov pa roj atoms diffuse maj mam hauv cov hlau, thiab vim qhov ntsuas kub thiab sijhawm kub thiab sijhawm tsis tau nkag mus rau hauv cov khoom siv (tshwj xeeb yog cov phiaj tuab). Cov txheej txheem no tsuas yog ntxiv dag zog rau saum npoo, tsis muaj hloov tag nrho cov muaj kev sib xyaw ua ke thiab cov qauv.
DC06's Ultra - Cov yam ntxwv muaj roj carbon):
DC06 muaj qhov tsis tshua muaj cov pa roj carbon (tsawg dua los yog sib npaug rau 0.008%). Txawm hais tias tom qab quenching, cov tub ntxhais tsis tuaj yeem tsim cov ntsiab lus yuav tsum muaj cov ntsiab lus carbon ntau dua lossis sib npaug rau 0.2%), tswj cov qauv ferrite mos. Yog li ntawd, carburizing tsis tuaj yeem nce cov tub ntxhais ua kom tawv tawv.
IV. Cov Ntawv Thov thiab Lwm Yam
Cov ntawv thov ntawm carburizing: Qhov uas yuav tsum tau ua tsuas yog cov nplaim dej tsis kam thaum tswj cov txheej txheem tawv (xws li cov npoo hnav txheej ntawm lub zog thiab bushings). Lub meej yas ntawm DC06 core tuaj yeem siv los nqus cov kev cuam tshuam loads, thaum ib txhij txhim kho kev tsis kam ua tsis kam los ntawm saum npoo hardening. Lwm txoj kev xaiv rau kev txhim kho nyuaj tag nrho: Yog tias qhov kev xav tau yooj yim heev ntawm DC06 yog qhov xav tau (piv txwv li cas, txias dua tshiab Yog tias cov khoom xa tuaj yeem ua tau, cov hlau roj carbon-carbon (piv txwv li, 1045) tuaj yeem siv, thaum lawv muab ntau qhov carburizing hardening nyhuv.
Hauv cov ntsiab lus, carburizing yog "nyob hauv zos muaj zog ntxiv txoj kev" rau DC06, tsis yog "tag nrho cov txheej txheem nyuaj." Nws cov tseem ceeb tus nqi lus dag nyob rau hauv lub rooj sib npaug hnav kev tiv thaiv tsis kam thiab cov tub ntxhais muaj kev nruj, tsis yog nce zuj zus kev nyuaj.
