Kunezindlela eziyishumi ezivame ukusetshenziswa zokucisha inqubo yokwelapha ukushisa, okuhlanganisa okukodwa okuphakathi (amanzi, amafutha, umoya) ukucisha; ukucisha okubili okuphakathi; i-martensite graded quenching; indlela yokucisha i-martensite graded ngezansi kwephuzu lika-Ms; indlela yokucisha isothermal; indlela yokuqeda i-compound; precooling isothermal quenching indlela; ukubambezeleka ukupholisa indlela yokucisha; ukucima indlela yokuzibamba; indlela yokucisha isifutho, njll.
1. I-Single medium (amanzi, amafutha, umoya) ivala
Ukucima okukodwa-okumaphakathi (amanzi, uwoyela, umoya): Indawo yokusebenza eshiselwe ezingeni lokushisa elicishayo icinywa ibe yindawo yokucisha ukuze iphole ngokuphelele. Lena indlela elula yokucisha futhi ivame ukusetshenziselwa insimbi ye-carbon steel kanye nensimbi yokusebenza yealloy enomumo olula. I-medium quenching ikhethwa ngokuya nge-coefficient yokudlulisa ukushisa, ukuqina, ubukhulu, ukuma, njll kwengxenye.
2. Ukucisha okuphakathi kabili
Ukucisha okukabili-okumaphakathi: Ucezu lokusebenza olushiselwe kuzinga lokushisa lokucisha lupholiswa kuqala ukuze luvale iphoyinti lika-Ms endaweni yokucisha enamandla okupholisa ngamandla, bese ludluliselwa endaweni yokupholisa epholile kancane ukuze luphole kuya kuzinga lokushisa elilingana negumbi ukuze kufinyelele ukupholisa okuhlukile kokucisha. amazinga okushisa futhi anezinga lokupholisa elifanele Ngokulinganiselwe. Le ndlela ivame ukusetshenziselwa izingxenye ezinobunjwa obuyinkimbinkimbi noma ama-workpieces amakhulu enziwe nge-high-carbon steel ne-alloy steel. Izinsimbi zamathuluzi ekhabhoni nazo zivame ukusetshenziswa. Imidiya yokupholisa evame ukusetshenziswa ihlanganisa uwoyela wamanzi, amanzi-nitrate, umoya-manzi, nomoya kawoyela. Ngokuvamile, amanzi asetshenziswa njengendawo yokucisha yokupholisa ngokushesha, futhi uwoyela noma umoya usetshenziswa njengendlela yokucisha ukupholisa kancane. Umoya awuvamile ukusetshenziswa.
3. Martensite graded quenching
I-Martensitic graded quenching: insimbi iyaqinisekiswa, bese icwiliswa endaweni ewuketshezi (ibhavu likasawoti noma i-alkali bath) enezinga lokushisa eliphakeme kancane noma eliphansi kancane kunephuzu elingenhla le-Martensite lensimbi, futhi igcinwe isikhathi esifanele kuze kube ngaphakathi futhi. izindawo zangaphandle zezingxenye zensimbi Ngemva kokuba izendlalelo zifinyelele izinga lokushisa eliphakathi nendawo, zikhishwa ukuze zipholiswe umoya, futhi i-austenite epholile iguqulwa kancane ibe yi-martensite ngesikhathi sokupholisa. inqubo yokucima. Ngokuvamile isetshenziselwa ama-workpieces amancane anezimo eziyinkimbinkimbi kanye nezidingo eziqinile zokuguqulwa. Le ndlela iphinde isetshenziselwe ukucisha insimbi enesivinini esikhulu namathuluzi ensimbi anengxubevange ephezulu kanye nezibunji.
4. Indlela yokucisha i-Martensite graded ngezansi kwephoyinti likaNksz
I-Martensite graded quenching indlela engaphansi kukaNks phuzu: Uma izinga lokushisa lokugeza liphansi kunoNks wensimbi yokusebenzela futhi liphakeme kune-Mf, ucezu lokusebenza luphola ngokushesha kubhavu, futhi imiphumela efanayo nokucisha okuhleliwe kusengatholakala uma usayizi mkhulu. Ivamise ukusetshenziselwa izingcezu zensimbi ezinkulu ezinokuqina okuphansi.
5. I-Bainite isothermal quenching indlela
Indlela yokucisha i-Bainite isothermal: Isiqephu sokusebenza sicinywa kubhavu enezinga lokushisa eliphansi le-bainite lensimbi ne-isothermal, ukuze uguquko oluphansi lwe-bainite lwenzeke, futhi ngokuvamile lugcinwa kubhavu imizuzu engama-30 kuya kwengama-60. Inqubo ye-bainite austempering inezinyathelo ezintathu eziyinhloko: ① ukwelashwa kwe-austenitizing; ② ukwelashwa kokupholisa kwangemva kwe-austenitizing; ③ bainite ukwelashwa isothermal; evame ukusetshenziswa ensimbi ye-alloy, insimbi ephezulu ye-carbon steel izingxenye ezincane kanye ne-ductile iron castings.
6. Indlela yokucisha inhlanganisela
Indlela yokucisha inhlanganisela: qala ngokucisha i-workpiece ibe ngaphansi kukaNks ukuze uthole i-martensite enengxenye yevolumu engu-10% kuya ku-30%, bese i-isotherm endaweni ephansi ye-bainite ukuze uthole izakhiwo ze-martensite kanye ne-bainite zezingxenye zokusebenza ezinkulu ze-cross-section. Kuvame ukusetshenziswa i-Alloy tool steel workpieces.
7. Indlela yokupholisa kuqala kanye ne-isothermal quenching
Indlela yokucisha i-isothermal yangaphambi kokupholisa: ebizwa nangokuthi ukushisa kwe-isothermal quenching, izingxenye ziqale zipholiswe ebhavini elinezinga lokushisa eliphansi (elikhudlwana kunoNks), bese lidluliselwa kubhavu elinokushisa okuphezulu ukuze kubangele ukuthi i-austenite ibe nokuguqulwa kwe-isothermal. Ifanele izingxenye zensimbi ezinobunzima obumpofu noma ama-workpieces amakhulu okumele aqiniswe.
8. Indlela yokupholisa ebambezelekile nendlela yokucisha
Indlela yokucisha ukupholisa ebambezelekile: Izingxenye ziqala zipholiswe kusengaphambili emoyeni, emanzini ashisayo, noma kubhavu kasawoti ezingeni lokushisa elingaphezudlwana kwe-Ar3 noma i-Ar1, bese kwenziwa ukucisha okukodwa okumaphakathi. Ivame ukusetshenziselwa izingxenye ezinobunjwa obuyinkimbinkimbi kanye nobukhulu obuhlukahluka kakhulu ezingxenyeni ezihlukahlukene futhi ezidinga ukuguqulwa okuncane.
9. Indlela yokucisha nokuzithiba
Indlela yokucisha nokuzithiba: Yonke into yokusebenza okufanele icutshungulwe iyashiswa, kodwa ngesikhathi sokucisha, ingxenye kuphela edinga ukuqina (imvamisa ingxenye esebenzayo) icwiliswa oketshezini olucishayo bese ipholiswa. Lapho umbala womlilo wengxenye engacwilisiwe unyamalala, ngokushesha uwukhiphe emoyeni. Ukupholisa okumaphakathi inqubo yokucisha. Indlela yokucisha nokuzithiba isebenzisa ukushisa okusuka kumongo okungapholiswanga ngokuphelele ukuze kudluliselwe phezulu ukuze kuthukuthelise indawo engaphezulu. Amathuluzi avame ukusetshenziselwa ukumelana nomthelela njengamashizolo, izibhakela, izando, njll.
10. Futha indlela yokucisha
Indlela yokucisha isifutho: Indlela yokucisha lapho amanzi efafazwa khona endaweni yokusebenza. Ukugeleza kwamanzi kungaba kukhulu noma kuncane, kuye ngokujula okudingekayo kokucisha. Indlela yokucisha isifutho ayenzi ifilimu ye-steam ebusweni bomsebenzi, ngaleyo ndlela iqinisekise ungqimba oluqinile olujulile kunokucisha amanzi. Isetshenziselwa kakhulu ukucisha indawo yendawo.
