Indlela yokushisa nokuphatha ama-camshafts?

1. Ukucisha okuqondile ngemva kokungcwatshwa kwe-carburizing kunezinzuzo zokusebenza kahle kokukhiqiza, izindleko eziphansi, kanye ne-oxidative decarburization. Kodwa-ke, ngenxa yokushisa okuphezulu kwe-carburizing, okusanhlamvu kwe-austenite kuyakhula, i-martensite i-coarser ngemva kokucisha, futhi i-austenite egciniwe Kukhona nemizimba eminingi, ngakho-ke ukumelana nokugqoka kanye nokuqina akubi. Ifanele kuphela insimbi enohlamvu oluhle kanye nezingxenye ezinezidingo eziphansi zokumelana nokugqokwa noma izingxenye ezithwala umthwalo ophansi

2. Ukucisha kanye nje kungemva kokuba i-carburizing ipholiswe kancane kancane, bese ishisisa kabusha ezingeni lokushisa elingaphezu kwezinga lokushisa elibucayi bese liyacinywa. Uma kuqhathaniswa nokucisha okuqondile, ukucisha ngesikhathi esisodwa kungacwengisa isakhiwo sensimbi ngezinga elithile. Uma izidingo zesakhiwo esiwumgogodla ziphezulu, izinga lokushisa lokushisa lokucisha lingaphezulu kancane kune-Ac3. Okwezingxenye ezingalayishiwe kakhulu kodwa ezinokumelana nokugqokwa okuphezulu kanye nezidingo zokusebenza kokuqina okuphezulu phezulu. Izinga lokushisa lokucisha kufanele libe ngu-30℃～50℃ ngaphezu kwe-Ac1, ukuze ungqimba olungaphezulu lwezinhlamvu lucwengisiswe, kodwa isakhiwo esiyinhloko ngeke sithuthukiswe kakhulu, futhi ukusebenza kuzoba kubi kakhulu.

3. Ukucisha okwesibili Ngensimbi enezakhiwo eziphezulu zemishini noma insimbi eqinile eqinile, ukucisha okwesibili kufanele kusetshenziswe. Inhloso yokucisha kokuqala ukuthuthukisa isakhiwo esiwumgogodla, futhi izinga lokushisa lokushisa lingu-30℃～50℃ ngaphezu kwe-Ac3. Inhloso yokucisha kwesibili iwukucwenga ukwakheka kongqimba olungaphezulu ukuze kutholwe i-martensite ecolekile kanye nosimende wesibili osatshalaliswe ngokulinganayo. Izinga lokushisa lokushisisa lingu-30℃～50℃ ngaphezu kwe-Ac1.
