Ukwelashwa kokushisa kwensimbi ngokuvamile kuhlanganisa ukucisha, ukufudumeza kanye nokudonsa.Ukwelashwa kokushisa kwensimbi kuthinta izakhiwo zezinto zensimbi.
1, Ukucisha: Ukucisha ukushisa insimbi ku-800-900 degrees, uyigcine isikhathi esithile, bese uyipholisa ngokushesha emanzini noma emafutheni, okungathuthukisa ubulukhuni futhigqoka ukumelana kwensimbi, kodwa ukwandisa ukubola kwensimbi.
Izinga lokupholisa linquma umphumela wokucisha.Lapho ukupholisa kushesha, kukhuphuka ubulukhuni nokuqina kwensimbi, kodwa kukhulu ukuqina.Impahla yokucisha yensimbi iyanda ngokwanda kokuqukethwe kwekhabhoni.Insimbi enokuqukethwe kwekhabhoningaphansi kuka-0.2% akukwazi ukucinywa futhi kuqiniswe.
Lapho ipayipi lishiselwe nge-flange, ukushisa eduze kwe-weld kufana nokucisha, okungase kubangele ukuqina.Kodwa-ke, insimbi ye-carbon ephansi enokuqukethwe kwekhabhoni engaphansi kuka-0.2% ngeke iqiniswe ngokucisha, okungesinye sezizathu zokuthi kungani insimbi ephansi ye-carbon ibe nokushisela okuhle.
2. I-Tempering: Insimbi ecishiwe iqinile futhi iyashwabana, futhi idala ukucindezeleka kwangaphakathi.Ukuze kuncishiswe le brittleness eqinile futhi kuqedwe ukucindezeleka kwangaphakathi, insimbi ecishiwe ivame ukushiswa ibe ngaphansi kuka-550 ° C, bese ipholisa ngemva kokugcinwa kokushisa ukuze kuthuthukiswe ukuqina kanye nepulasitiki yensimbi futhi ihlangabezane nezidingo zokusetshenziswa.
3. Anealing: Ukuze unciphise ubulukhuni futhi uthuthukise ipulasitiki yensimbi, lula ukucubungula, noma uqede ukuqina okunzima nokucindezeleka kwangaphakathi okukhiqizwa ngesikhathi sokupholisa nokushisela, insimbi ingashiswa ibe ngama-800-900 degrees, futhi ipholiswe kancane kancane ngemva kokugcinwa kokushisa ukuhlangabezana nezidingo zokusetshenziswa.Isibonelo, insimbi emhlophe efakwe ku-900-1100 degrees inganciphisa ubulukhuni nokuqina futhi ithole ukusebenziseka kalula.
