High alloy zitsulomwatsatanetsatane ang'onoang'ono m'mimba mwake opanda chitsulo chitoliropafupifupi sagwiritsa ntchito mwachindunji quenching ndondomeko;Pamene kuchuluka kwa austenite yosungidwa kumafunika kwambiri, chitsulo chochepa cha alloy sichidzazimitsidwa mwachindunji.Vuto lenileni ndi mawonekedwe a ma ripples pamwamba pa amwatsatanetsatane ang'onoang'ono m'mimba mwake opanda chitsulo chitoliro(monga magiya ozungulira kapena a hypoid) pansi pa katundu wogwira ntchito.
Kuti muchepetse kuchuluka kwa austenite yosungidwa ndi mapindikidwe pakuzimitsidwa mwachindunji, kuziziritsa kusanachitike kungagwiritsidwe ntchito kuyandikira kutentha kwa Ar1 mutatha kuzimitsa ndikuzimitsa.Chitoliro cholondola chaching'ono chachitsulo chosasunthika chimathanso kuzimitsidwa poyamba chikasamutsidwa kung'anjo yokwera pang'ono kuposa kutentha kwa Ar1.Pambuyo pozimitsa ndi kuzimitsa, chitoliro chaching'ono cholondola chachitsulo chosasunthika chimatha kuyatsanso kutentha pamwamba pa Ac1, kupititsa patsogolo tirigu ndikuchepetsa kuchuluka kwa austenite yotsalira.
The mwatsatanetsatane yaing'ono awiriozizira adagulung'undisa zitsulo chitoliroimazimitsidwa mwachindunji kuti ipeze mphamvu yapamwamba kwambiri ndi kuuma, koma kulimba kwake sikwapamwamba.Kuuma kwa carburized layer kungayesedwe ndi fayilo.Kuuma kungathe kuchepetsedwa chifukwa cha kukhalapo kwa austenite yotsalira mu chitoliro chaching'ono chosasunthika chachitsulo cha aloyi.Njirayi imathanso kuchepetsa simenti pamalire ambewu.Pamene Machining ndi carburized pamwamba mwatsatanetsatane yaing'ono caliberChitoliro chachitsulo chosasinthikapakufunika, kuziziritsa pang'onopang'ono kapena kuzizira kumatengedwa.
Ngati mkulu hardenability zitsulo amasankhidwa kapena kukhudzidwa ndi zipangizo, ngakhale kuzirala pang'onopang'ono, pamwamba yaing'ono m'mimba mwake mwatsatanetsatane chowala wandiweyani khoma chitoliro akadali ndi mkulu kuuma.Pankhaniyi, chithandizo chofewa chiyenera kutengedwa.Kuti mupewe mvula yamtaneti ya carbide, kuzizira kwapakatikati kuyenera kutengedwa.Samalani kuti mupewe decarburization panthawi yozizila pang'onopang'ono.Pambuyo pake, zitsulo zozimitsidwa ndi madzi ziyenera kugwiritsidwa ntchito.Pambuyo pobisa, kuziziritsa pang'onopang'ono kapena kuzimitsa mafuta kungagwiritsidwe ntchito kuyenga mbewuzo pakati pa chitoliro chaching'ono chopanda msoko popanda kupindika kapena kusweka.
Munjira yochizira kutentha kwa kuzimitsa kambiri, carburizing ndi kuziziritsa kutsatiridwa ndikuzimitsanso kuziziritsa, kuzimitsa pamwamba kumatha kuzindikirika ndi kuzimitsa pamwamba, ndipo njirazi zitha kugwiritsidwanso ntchito.Pakuti mwatsatanetsatane mipope yaing'ono yopanda msokonezo zitsulo okhutira mkulu aloyi, ndi bwino kutengera njira njira pafupi quenching mwachindunji, ndiye kutenthetsanso kwa 15 ~ 25 ℃ (25 ℃ ~ 50 ℃) pamwamba chapakati kusintha mfundo kutentha (ndithudi, kupitirira kusintha kwapamwamba).
The kutentha ndondomeko maximizes mphamvu ya pachimake ya yaing'ono m'mimba mwake mkulu-mwatsatanetsatane msoko chitoliro ndipo ali kulimba wabwino.Pafupifupi ma carbide onse otsala padziko lapansi amasungunuka.Ngakhale zotsalira za austenite zili mu ndondomeko yotereyi mwatsatanetsatane yaing'ono m'mimba mwake ozizira adagulung'undisa opanda chitsulo chitoliro ndi zochepa kuposa kuzimitsa mwachindunji, izo zidzasungidwa pang'ono.The deformation ndi yaikulu kuposa ya kuzimitsidwa mwachindunji, koma mkati mwa njira yovomerezeka.Mofanana ndi kuzimitsa kwachindunji, njira iyi siigwiritsidwe ntchito ngati chitsulo cha carbon wamba.
Pambuyo pang'onopang'ono kuzirala kapena kuzimitsa, ndi madzi zitsulo akhoza reheated kuti gawo kusintha kutentha pang'ono kuposa wosanjikiza carburized.Mwachitsanzo, yaing'ono m'mimba mwake aloyi mwatsatanetsatane msokonezo chitoliro akhoza reheated pambuyo carburizing ndi pang'onopang'ono kuzirala, chifukwa sangathe yeretsani njere ndi kuzimitsa, kuti kuuma kwake ndi otsika, mapindikidwe ang'onoang'ono, ndi kulimba ndi zolimbitsa;Chosanjikiza chapamwamba chimakhala ndi ma carbides osasunthika, motero amakhala ndi kuuma kwakukulu ndi kuphulika;Mwachitsanzo, chitoliro chaching'ono chachitsulo chosasunthika cholondola chimatenthedwanso pambuyo pobisa ndi kuzimitsa, ndipo njereyo imayengedwa bwino.Pakatikati imakhala yolimba kwambiri, yotsika kwambiri, ndipo pamwamba ilibe simenti ya maukonde, kotero kuuma kumakhala kwakukulu komanso kulimba kwake ndikwabwino, koma choyipa ndichakuti mapindikidwewo ndi akulu.
