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

1, ukucisha + izinga lokushisa eliphezulu (okwaziwa nangokuthi ukucisha kanye nokushisa)

Ipayipi lensimbi lishiselwa ekushiseni okucisha, ukuze isakhiwo sangaphakathi sepayipi yensimbi siguqulwe sibe yi-austenite, bese sipholile ngokushesha kunesivinini esibucayi sokucisha, ukuze isakhiwo sangaphakathi sepayipi yensimbi siguqulwe sibe yi-martensite, bese sivutha ngokushisa okuphezulu, ekugcineni, isakhiwo sepayipi yensimbi siguqulwa sibe yi-sopranite eqinile. ukuqina kwepayipi lensimbi.

2, normalizing (owaziwa nangokuthi normalizing)

Ngemva kokushisa ipayipi yensimbi ekushiseni okujwayelekile, isakhiwo sangaphakathi sepayipi yensimbi siguqulwa ngokuphelele sibe isakhiwo se-austenite, bese inqubo yokushisa ukushisa ipholile ngomoya njenge-medium.Ngemva kokujwayelekile, izakhiwo zensimbi ezahlukene zingatholakala, njenge-pearlite, i-bainite, i-martensite, noma inhlanganisela yazo.Le nqubo ayikwazi nje ukucwenga okusanhlamvu, ukwakheka okufanayo, ukuqeda ukucindezeleka kwepayipi nokusebenza kwayo okuqinile.

I-normalizing + tempering

Ishubhu lensimbi lishiselwa ekushiseni okujwayelekile, ukuze isakhiwo sangaphakathi seshubhu lensimbi siguqulwe ngokuphelele sibe yisakhiwo se-austenite, bese sipholiswa emoyeni, bese siyabambisana. ubulukhuni.

4 , ukuthunga

Kuyinqubo yokwelapha ukushisa lapho ishubhu lensimbi lishiselwa lize lifinyelele izinga lokushisa le-annealing futhi ligcinwe isikhathi esithile, bese lipholiswa lize lifike ezingeni elithile lokushisa ngesithando somlilo. Yehlisa ubulukhuni bepayipi lensimbi, uthuthukise ipulasitiki yalo, ukuze kube lula ukucutshungulwa kokuguqulwa okubandayo noma okubandayo; Cwenga okusanhlamvu, susa amaphutha e-microstructure, ukwakheka okufanayo kwesakhiwo sangaphakathi kanye nokwakheka kwepayipi, ukuvimbela ukusebenza kwepayipi lensimbi elingaphansi noma ukuvimbela ukucindezeleka kwepayipi. deformation noma ukuqhekeka.

5. Ukwelashwa kwesixazululo

I-tube yensimbi ishiselwa ekushiseni kwesisombululo, ukuze i-carbides nezakhi ze-alloying zihlakazwe ngokugcwele futhi ngokulinganayo ku-austenite, bese ishubhu lensimbi selipholile ngokushesha, ukuze i-carbon ne-alloying izakhi abanaso isikhathi sokushona, futhi inqubo yokushisa ukushisa kwesakhiwo esisodwa se-austenite iyatholakala. ukucubungula i-deformation; Buyisela ukumelana nokugqwala kwensimbi engagqwali.
