1. I-Beryllium oxide:I-beryllium oxide ayilahleki nje kuphela insimbi eningi, kodwa futhi yehlisa izinga eliphezulu lezinto zokubumba kanye nempilo yesevisi yeukufa kobumba. Uma ucindezelwe ensimbi, iama-forgingsizolahlwa. Ukwehluleka ukususa i-beryllium oxide kuzothinta inqubo yokujika.
2. I-Decarburization:I-Decarburization ibhekisela esimweni sokuthi yonke noma ingxenye yekhabhoni engaphezulu kwensimbi iyashiswa. I-Decarburization yenza ingaphezulu le-workpiece libonakale izindawo ezithambile, linciphise ubulukhuni bobuso, ukumelana nokugqoka kanye namandla okukhathala.
3. Ukushisa ngokweqile kanye nokushiswa ngokweqile:Ukushisa okweqile kubhekisela ensimbi ekushiseni okungaphezu kwezinga lokushisa elivumelekile, ukuze ukukhula okusanhlamvu kube amaholoholo. Ukushisa ngokweqile akusizi ekwelapheni ukushisa, ukuze ama-forging abe ama-brittle futhi izakhiwo zemishini zincishiswe, kodwa zingaqedwa ngokujwayelekile noma ngokufaka i-annealing ngemva kwalokho.ukuqamba. Ukushiswa ngokweqile kubhekisela entweni yama-oxides noma ukuncibilika kwezinsimbi ngenxa yesikhathi sokushisisa sibe side kakhulu nezinga lokushisa liphezulu kakhulu. Umkhuhlane awukwazi ukulungiseka.
4. Ingcindezi:ngenxa yomehluko phakathi kwangaphakathi nangaphandle kwensimbi, ukunwetshwa akulingani, futhi ukucindezeleka kwangaphakathi kukhiqizwa, okubizwa ngokuthi ukucindezeleka okushisayo. Ukushintsha okulandelanayo kwesakhiwo se-metallographic okubangelwa ukushisa nakho kubangela ukucindezeleka, okubizwa ngokuthi i-microstructure stress. Lokhu kuzokwenza i-workpiece ekuqhumeni kokushisa, kubangele umshini wokusebenza ngemuva kokucubungula imoto nokuqhekeka.
5. Ukuphuka kwengxenye yesiphambano:leli phutha libhubhisa ukubunjwa kwamakhemikhali kanye nokufana kwe-microstructure yensimbi, kunciphisa ubulukhuni bokucisha futhi kulimaze izakhiwo zemishini. Uma izinga lokushisa le-annealing liphezulu kakhulu futhi liholela esigabeni se-graphite, ngeke kube lula ukusika nokucisha ukushisa nokuguqulwa. Kodwa uma i-annealing ngaphansi kokushisa noma izinga lokushisa eliphansi, i-pearlite ayikwazi ukuqedela ukuhwebelana kwembulunga yonke, ayihambisani nokusika nokwelashwa kokushisa okwalandela.
6. i-hard and brittle mesh carbide: yenza buthaka amandla okubopha phakathi kwezinto ze-crystal, izakhiwo zemishini zibi kakhulu, ikakhulukazi ukuqina komthelela kuyancipha, kodwa kungathuthukiswa noma kuqedwe ngokujwayelekile. Uma kukhona i-carbide eboshwe, izokwenza ubulukhuni nesakhiwo sokucisha nokushisa kungalingani, futhi kube lula ukuguquguquka, okubuye kube isici sesakhiwo esinebhande se-pearlite ne-ferrite eduze nokuqondisa kokucubungula ukuguquguquka. Ngesikhathi esifanayo, kuzophinde kunciphise i-plasticity nokuqina kwensimbi, ukuze ubukhulu bemishini bungazinzile, ukugqoka kwamathuluzi okusheshayo.
