Forgingskweinqubo yokuqamba, ukwelashwa ukushisa isixhumanisi esibaluleke kakhulu, ukwelashwa ukushisa cishe annealing, normalizing, quenching futhi tempering izinqubo ezine eziyisisekelo, ngokuvamile eyaziwa ngokuthi metal ukushisa ukwelashwa "umlilo ezine".

okukodwa, ukwelashwa kokushisa kwensimbi komlilo - annealing:
I-1, i-annealing iwukushisa i-workpiece ezingeni lokushisa elifanele, ngokusho kwempahla kanye nosayizi we-workpiece usebenzisa isikhathi sokubamba esihlukene, bese ukupholisa kancane, inhloso ukwenza inhlangano yangaphakathi yensimbi ifinyelele noma isondele esimweni sokulingana, ukuthola. ukusebenza kahle kwenqubo nokusebenza, noma ukucisha okwengeziwe ukulungiselela izicubu.
2, inhloso yokukhishwa:

① Ukuthuthukisa noma ukuqeda insimbi ekubunjweni, ukubumba, ukugingqa kanye nenqubo yokushisela okubangelwa ukukhubazeka okuhlukahlukene kwenhlangano kanye nengcindezi eyinsalela, ukuvimbela ukuwohloka komsebenzi, ukuqhekeka.

② Thambisa ucezu lokusebenza ukuze usike.

③ Cwenga okusanhlamvu futhi uthuthukise isakhiwo ukuze uthuthukise izakhiwo zemishini ze-workpiece.(4) Lungiselela ukwelashwa kokushisa kokugcina (ukucisha, ukushisa).
Okwesibili, ukwelashwa kokushisa kwensimbi komlilo wesibili - ukujwayelekile:
I-1, i-normalization iwukushisa i-workpiece ezingeni lokushisa elifanele ngemva kokupholisa emoyeni, umphumela wokulinganisa ufana no-annealing, kodwa isakhiwo sihlanzekile, ngokuvamile sisetshenziselwa ukuthuthukisa ukusebenza kokusika kwezinto, kodwa futhi ngezinye izikhathi sisetshenziselwa izingxenye ezithile. ngezidingo eziphansi njengokwelashwa kokushisa kokugcina.
2, inhloso normalizing:
①Ingakwazi ukuqeda ukwakheka okusanhlamvu okushisayo okushisa kakhulu kanye nesakhiwo se-widnells sokuphonsa, ukubumba nokushisela izingxenye, kanye nesakhiwo esinebhande ezintweni ezigoqayo;Ukucwenga okusanhlamvu;Futhi ingasetshenziswa njengendlela yokwelashwa kwangaphambi kokushisa ngaphambi kokucisha.
② Ingakwazi ukuqeda i-cementite yesibili yenethiwekhi, futhi icwenge i-pearlite, ingathuthukisi izakhiwo zemishini kuphela, kodwa futhi ivumelane nekusasa le-spheroidizing annealing.
③Usimende wamahhala emngceleni wokusanhlamvu ungasuswa ukuze kuthuthukiswe ukusebenza komdwebo ojulile.
Okwesithathu, ukwelashwa kokushisa kwensimbi komlilo wesithathu - ukucisha:
I-1, ukucisha ukushisa i-workpiece ngemva kokugcina ukushisa, emanzini, uwoyela noma omunye usawoti wezinto ezingaphili, isixazululo samanzi aphilayo nokunye ukupholisa okuphakathi kokucisha ngokushesha.Ngemva kokucisha, insimbi iba nzima, kodwa ngesikhathi esifanayo iba brittle.
2. Inhloso yokucisha:
①Thuthukisa izakhiwo zemishini zezinto zensimbi noma izingxenye.Isibonelo: thuthukisa ubulukhuni nokugqoka ukumelana kwamathuluzi, ama-bearings, njll., thuthukisa umkhawulo wokunwebeka weziphethu, uthuthukise izakhiwo ezibanzi zemishini yezingxenye ze-shaft, njll.
②, thuthukisa izakhiwo ezibonakalayo noma izakhiwo zamakhemikhali zensimbi ethile ekhethekile.Njengokuthuthukisa ukumelana nokugqwala kwensimbi engagqwali, kwandisa uzibuthe unomphela wensimbi kazibuthe, njll.
Okwesine, ukwelashwa kokushisa kwensimbi komlilo wesine - ukushisa:
1, ukushisa ukuze kuncishiswe ukuqina kwensimbi, ukucisha insimbi ezingeni lokushisa elithile elifanele ngaphezu kwezinga lokushisa elingaphezu kwegumbi nangaphansi kuka-710 ℃ isikhathi eside, bese ukupholisa, le nqubo ibizwa ngokuthi i-temering.
2, inhloso yokunciphisa:
①, yehlisa ukucindezelwa kwangaphakathi futhi inciphise ukuqina, kunokuningi ukucindezelwa kanye nokuba brittleness kwezingxenye ezicishayo, njengokungathulisi okufika ngesikhathi kuvame ukukhiqiza ukuwohloka ngisho nokuqhekeka.
② Lungisa izakhiwo zemishini yesiqeshana sokusebenza.Ngemva kokucisha, i-workpiece inobulukhuni obuphezulu kanye ne-brittleness.Ukuze kuhlangatshezwane nezidingo ezahlukene zokusebenza ze-workpiece ehlukahlukene, ubulukhuni, amandla, ipulasitiki kanye nokuqina kungalungiswa ngokushisa.
③, zinzisa usayizi wocezu lokusebenza.Ngokuthambisa, isakhiwo se-metallographic singazinziswa ukuze kuqinisekiswe ukuthi ukuguquguquka ngeke kwenzeke enqubweni yokusebenzisa esikhathini esizayo.
④, thuthukisa ukusebenza kwensimbi ye-alloy.
