Lisebelisoa tsa metallurgy tsa phofo le lihlahisoa tse ikhethileng, ho latela litlhoko tse fapaneng tsa ts'ebetso ea sehlahisoa, li tšoana le kalafo e tloaelehileng ea mocheso.Kamora ho futhumatsa le ho tima, ba tlameha ho halefa ho fokotsa khatello ea maikutlo le ho tima brittleness, ho tsitsisa sebopeho, le ho fihlela thepa e hlokahalang ea mochini.Hangata mocheso o tlase oa mocheso o etsoa.Mefuta e meraro ea induction tempering, mocheso oa sebōpi le ho itšehla thajana hangata li sebelisoa tlhahisong.
① Induction tempering The workpiece e tingoeng e futhumatsoa ka mokhoa o ts'oanelang ho fihlela sepheo sa ho futhumatsa, ke hore, ka mor'a hore mochini oa mosebetsi o futhusoe ke inductor le spray-pholile, ho futhumatsa le ho futhumatsa ho lokela ho etsoa hang-hang.Ka lebaka la nako e khutšoanyane ea ho futhumatsa, microstructure e na le ho hasana ho hoholo.E ka fumana khanyetso e phahameng ea ho roala le boima bo phahameng ba tšusumetso, joalo-joalo e loketse ka ho khetheha bakeng sa tempering ea li-shafts, li-sleeve le likarolo tse ling tse tsoelang pele ho futhumala le ho tima.
②Ho futhumala ka sebōping Mosebetsi oa ho sebetsa o halefile ka sebōping sa sekoting, sebōping sa oli kapa lisebelisoa tse ling ka mor'a ho tima maqhubu a phahameng.Mocheso oa mocheso o lokela ho khethoa ho ea ka boima bo hlokahalang le ts'ebetso, le mocheso oa mocheso le Nako, joalo ka lisebelisoa tse phahameng tsa k'habone le lisebelisoa tsa ho lekanya, tšepe e bohareng ea k'habone kapa lisebelisoa tsa tšepe tsa carbon alloy le spline shafts, alloy cast iron camshafts le likarolo tse ling. , e hloka sekhahla se tlase sa ho tima ho pholile, hangata ho sebelisoa ho qoelisoa ka metsing kapa metsing.Boholo ba bona bo halefile ho 150 ~ 250 ℃, 'me nako ka kakaretso ke 45 ~ 120min.E sebelisoa haholo bakeng sa tempering ea li-workpieces tse nang le boholo bo bonyenyane, sebōpeho se rarahaneng, lerako le tšesaane le lera le sa tebang le thata ho tiisa hore ho thata haholo le ho apara ho hanyetsa bokaholimo ba likarolo.Hloka.
③ Ho itšehla thajana Khaotsa ho pholisa ka mor'a ho fafatsa kapa ho qoelisoa, 'me u sebelise mocheso o teng ka hare ho workpiece e tingoeng ka mor'a ho tima ho etsa hore sebaka sa quenching se nyolohele mocheso o itseng hape ho finyella litlhoko tsa mocheso,' me mocheso oa oona o lokela ho ba o phahameng ho feta mocheso oa mocheso. seboping.Ka kakaretso, bokaholimo ba likarolo bo na le mocheso o phahameng ka mor'a ho pholile ka metsotsoana e 3 ho isa ho e 10.E le nako ea ho itšehla thajana, likarolo tse kholo ke 6s 'me tse nyenyane ke 40s ho qeta ho itšoara.
