Momwe mungapangire carburize ndikuwotcha camshafts?

1. Kuzimitsa kwachindunji pambuyo pa kubisala kwa carburizing kuli ndi ubwino wopanga bwino kwambiri, mtengo wotsika, ndi oxidative decarburization. Komabe, chifukwa cha kutentha kwambiri kwa carburizing, mbewu za austenite zimakula, martensite imakhala yolimba itatha kuzimitsidwa, ndi kusungidwa kwa austenite Palinso matupi ochulukirapo, kotero kuvala kukana ndi kulimba kumakhala kosauka. Zoyenera zokha zitsulo zokhala bwino komanso zigawo zokhala ndi zofunikira zochepa zokana kuvala kapena magawo otsika onyamula katundu

2. Kuzimitsa kamodzi kokha ndi pambuyo pozimitsa carburizing pang’onopang’ono, ndikutenthedwanso ku kutentha pamwamba pa kutentha kwakukulu ndikuzimitsidwa. Poyerekeza ndi kuzimitsa kwachindunji, kuzimitsa kamodzi kokha kungathe kuyeretsa chitsulocho mpaka kufika pamlingo wina. Zofunikira zamapangidwe apakati zimakhala zapamwamba, kutentha kwa chozimitsa kumakhala kokwera pang’ono kuposa Ac3. Kwa magawo omwe sali olemedwa kwambiri koma amakhala ndi kukana kwamphamvu kovala komanso kulimba kwa magwiridwe antchito apamwamba. Kutentha kozimitsa kuyenera kukhala 30 ℃ ~ 50 ℃ pamwamba pa Ac1, kuti njere zosanjikiza pamwamba ziyeretsedwe, koma mawonekedwe apakati sangawongoleredwe bwino, ndipo magwiridwe ake azikhala oyipitsitsa pang’ono.

3. Kuzimitsa kwachiwiri Kwa zitsulo zokhala ndi makina apamwamba kwambiri kapena zitsulo zowonongeka kwambiri, kuzimitsa kwachiwiri kuyenera kugwiritsidwa ntchito. Cholinga cha kuzimitsa koyamba ndikuwongolera kapangidwe kake, ndipo kutentha kwa kutentha ndi 30 ℃ ~ 50 ℃ pamwamba pa Ac3. Cholinga cha kuzimitsidwa kwachiwiri ndikuwongolera mawonekedwe osanjikiza pamwamba kuti apeze martensite yabwino komanso kugawidwa kofananako simenti yachiwiri ya granular. Kutentha kwa kutentha ndi 30 ℃～50 ℃ pamwamba pa Ac1.
