Kunezindlela eziyishumi ezivame ukusetshenziswa zokucisha ezinqubweni zokwelashwa kokushisa, okuyi-single medium (amanzi, amafutha, umoya) ukucisha; Ukucisha okuphakathi kabili; Ukuqedwa kwe-martensite ngezigaba; Ukucinywa ngokwezigaba kwe-martensite ngaphansi kwephuzu likaNksz; I-Bainite isothermal quenching indlela; Indlela yokuqeda inhlanganisela; Indlela yokucisha i-isothermal ngaphambi kokupholisa; Indlela yokucisha ukupholisa ebambezelekile; Indlela yokunciphisa umzimba kanye nokunciphisa umzimba; Indlela yokucisha isifutho, njll.

1、 I-Single medium (amanzi, amafutha, umoya) ivala

Ukucisha okukodwa (amanzi, uwoyela, umoya): Ukucisha izinto zokusebenza ezishiselwe ukucisha izinga lokushisa endaweni yokucisha ukuze zizipholise ngokuphelele. Lena indlela elula yokucisha, evame ukusetshenziselwa insimbi ye-carbon kanye nezinsimbi zokusebenza ze-alloy ezinezimo ezilula. Indawo yokucisha izokhethwa ngokuya nge-coefficient yokudlulisa ukushisa, ukuqina, usayizi, ukuma, njll. kwengxenye.

3、 Isinyathelo sokucisha i-martensite Isinyathelo sokucisha i-martensite: insimbi iyaqinisekiswa, bese icwiliswa endaweni ewuketshezi (ibhavu likasawoti noma okugeza nge-alkali) ngezinga lokushisa elingaphezudlwana noma eliphansi kunephuzu lensimbi elingenhla le-martensite, futhi ligcinwe isikhathi esifanele. . Lapho izingqimba zangaphakathi nezingaphandle zezingxenye zensimbi zifinyelela izinga lokushisa eliphakathi, zikhishwa ukuze ziphole komoya, futhi i-austenite epholile kancane iguqulwa ibe i-martensite. Ngokuvamile esetshenziselwa ama-workpieces amancane anezimo eziyinkimbinkimbi kanye nezidingo eziqinile zokuguquguquka, le ndlela ibuye isetshenziselwe ukucisha insimbi enesivinini esikhulu kanye nesikhunta sensimbi ye-alloy ephezulu. 4、 Ukucinywa okulinganiselwe kwe-martensite ngezansi kwephuzu likaNks kucinywa ngokwezinga le-martensite ngaphansi kwephuzu likaNks: lapho izinga lokushisa lokugeza liphansi kunoNks wensimbi esetshenziselwa ucezu lokusebenzela kodwa liphakeme kune-Mf, i-workpiece iphola ngokushesha ebhavini, futhi imiphumela efanayo isengakwazi. kutholwe uma usayizi mkhulu. Okuvame ukusetshenziselwa izingcezu zokusebenza zensimbi ezinosayizi omkhulu ongaqinile. 5、 I-Bainite isothermal quenching Indlela ye-Bainite yokucisha isothermal: cisha ucezu lokusebenza endaweni yokugeza ezingeni lokushisa eliphansi le-bainite lensimbi ukuya ku-isothermal, ukuze likwazi ukuguqulwa okuphansi kwe-bainite, futhi ngokuvamile liyigcine kubhavu imizuzu engama-30~60. Inqubo yokucisha i-isothermal ye-bainite inezinyathelo ezintathu eziyinhloko: ① austenitizing; ② Ukupholisa ukwelashwa ngemva kwe-austenitization; ③ Ukwelashwa kwe-isothermal ye-Bainite; Ivame ukusetshenziswa ensimbi ye-alloy, insimbi ephezulu ye-carbon steel izingxenye ezincane, kanye ne-ductile iron castings. 6、 Indlela yokuqeda inhlanganisela

Indlela yokucisha inhlanganisela: i-workpiece icinywa ibe ngaphansi kukaNks ukuze kutholwe i-martensite enengxenye yevolumu engu-10% ~ 30%, bese i-isothermal endaweni ephansi ye-bainite ukuze kutholwe izakhiwo ze-martensite kanye ne-bainite yezingxenye zokusebenza ezinezingxenye ezinkulu eziphambanayo, ezivame ukusetshenziselwa ingxubevange ithuluzi steel workpieces. 7、 Indlela Yokucima Ngaphambi Kokupholisa Kwe-Isothermal Ukupholisa Ngaphambili Indlela Yokuqeda I-Isothermal: Eyaziwa nangokuthi I-Temperature Rise Isothermal Quenching, izingxenye ziqale zipholiswe endaweni yokushisa ephansi (enkulu kunoNks), bese zidluliselwa kubhavu lokushisa eliphezulu ukuze zibhekane nokuguqulwa kwe-isothermal ye-austenite. Ifanele izingxenye zensimbi ezinokuqina okubi noma izinto zokusebenza ezinobukhulu obukhulu obudinga ukucinywa kwe-isothermal.

8、 Indlela yokucisha ukupholisa ibambezelekile

Indlela yokucisha ukupholisa ebambezelekile: Izingxenye zipholiswa ngaphambili zibe izinga lokushisa elingaphezudlwana kwe-Ar3 noma i-Ar1 emoyeni, emanzini ashisayo, noma kubhavu kasawoti, bese zifakwa ngaphansi kokucinywa okuphakathi nendawo okukodwa. Ijwayele ukusetshenziselwa izingxenye ezinobumo obuyinkimbinkimbi, ukujiya okuhlukahlukayo ezingxenyeni ezihlukahlukene, futhi ezidinga ukuwohloka okuncane.

9, Indlela yokuzicisha: Shisisa zonke izinto zokusebenza ezicutshunguliwe, kodwa ngesikhathi sokucisha, izingxenye kuphela ezidinga ukuqina (imvamisa izingxenye ezisebenzayo) ezicwiliswa kwisisombululo sokucisha ukuze kuphole. Linda kuze kunyamalale izingxenye ezingacwilisiwe, bese uzikhipha ngokushesha ukuze ziphole emoyeni. Indlela yokuzicisha neyokuzishisa isebenzisa ukushisa okungapholiswanga ngokuphelele phakathi nendawo ukuze kudluliselwe phezulu, okubangela ukuthi ingaphezulu lizole. Amathuluzi avame ukusetshenziswa ukumelana nomthelela, njengamashizolo, izibhakela, izando, njll. 10、 Indlela yokucisha isifutho: Indlela yokucisha lapho amanzi efafazwa khona endaweni yokusebenza, futhi ukugeleza kwamanzi kungaba kukhulu noma kube kuncane, kuye ngokujula okudingekayo kokucisha. Indlela yokucisha isifutho ayenzi ifilimu yomhwamuko ebusweni bomsebenzi, oqinisekisa ukuthi kutholakala ungqimba oluqinile olujulile kunokucisha emanzini e-Xitong. Isetshenziselwa kakhulu ukucisha indawo yendawo.
