Inqubo yokwelapha ukushisa kwepayipi lensimbi ihlanganisa ikakhulukazi izigaba ezi-5 ezilandelayo:

1, ukucima + ukushisa okuphezulu (okwaziwa nangokuthi ukucima kanye nokushisa)

Ipayipi lensimbi lishiswa lifinyelele ekushiseni kokucima, ukuze isakhiwo sangaphakathi sepayipi lensimbi siguqulwe sibe yi-austenite, bese sipholiswa ngokushesha kunesivinini sokucima esibucayi, ukuze isakhiwo sangaphakathi sepayipi lensimbi siguqulwe sibe yi-martensite, bese siqiniswa ngokushisa okuphezulu, ekugcineni, isakhiwo sepayipi lensimbi siguqulwe sibe yi-sopranite eqiniswayo efanayo. Le nqubo ayikwazi nje ukuthuthukisa amandla nokuqina kwepayipi lensimbi, kodwa futhi ihlanganise ngokwasemzimbeni amandla, ukuqina kanye nokuqina kwepayipi lensimbi.

2, ukwenza kube ngokwejwayelekile (okwaziwa nangokuthi ukwenza kube ngokwejwayelekile)

Ngemva kokushisa ipayipi lensimbi ukuze lishintshe izinga lokushisa, isakhiwo sangaphakathi sepayipi lensimbi siguqulwa ngokuphelele sibe isakhiwo se-austenite, bese inqubo yokwelapha ukushisa ipholiswa ngomoya njengendlela ephakathi. Ngemva kokushintsha, kungatholakala izakhiwo zensimbi ezahlukene, njenge-pearlite, i-bainite, i-martensite, noma ingxube yazo. Le nqubo ayikwazi nje kuphela ukucwenga okusanhlamvu, ukwakheka okufanayo, isuse ukucindezeleka, kodwa futhi ithuthukise ubulukhuni bepayipi lensimbi kanye nokusebenza kwayo kokusika.

Ukulungisa + ukulinganisela

Ipayipi lensimbi lishiswa lifinyelele ezingeni lokushisa elijwayelekile, ukuze isakhiwo sangaphakathi sepayipi lensimbi siguqulwe ngokuphelele sibe yisakhiwo se-austenite, bese sipholiswa emoyeni, bese sishiswa. Isakhiwo sepayipi lensimbi sishiswa i-ferrite + pearlite ethambile, noma i-ferrite + bainite, noma i-bainite ethambile, noma i-martensite ethambile, noma i-sortensite ethambile. Inqubo ingazinzisa isakhiwo sangaphakathi sepayipi lensimbi futhi ithuthukise ukuqina kwayo.

4, ukubopha

Kuyinqubo yokwelapha ukushisa lapho ipayipi lensimbi lishiswa khona lifinyelele ekushiseni okubandayo futhi ligcinwe isikhathi esithile, bese lipholiswa lifinyelele ekushiseni okuthile ngesithando somlilo. Nciphisa ubulukhuni bepayipi lensimbi, uthuthukise ukwakheka kwalo, ukuze kube lula ukucubungula ukusika noma ukuguquka okubandayo okulandelayo; Cwenga okusanhlamvu, ususe amaphutha esakhiwo esincane, isakhiwo sangaphakathi kanye nokwakheka okufanayo, uthuthukise ukusebenza kwepayipi lensimbi noma ulungiselele inqubo elandelayo; Susa ukucindezeleka kwangaphakathi kwepayipi lensimbi ukuvimbela ukuguquka noma ukuqhekeka.

5. Ukwelashwa kwesisombululo

Ishubhu lensimbi lishiswa lifinyelele izinga lokushisa lesisombululo, ukuze ama-carbide nezinto ezixubayo zincibilike ngokuphelele nangokulinganayo ku-austenite, bese kuthi ishubhu lensimbi lipholiswe ngokushesha, ukuze izinto zekhabhoni nezinto ezixubayo zingabi nesikhathi sokuzinza, futhi kutholakale inqubo yokwelapha ukushisa kwesakhiwo esisodwa se-austenite. Umsebenzi wenqubo: isakhiwo sangaphakathi esifanayo sepayipi lensimbi, ukwakheka okufanayo kwepayipi lensimbi; Susa ukuqina enkambisweni yokucubungula ukuze kube lula ukucubungula okulandelayo kokuguqulwa kokubanda; Buyisela ukumelana nokugqwala kwensimbi engagqwali.
