Njengengxenye eyinhloko yokuxhumeka kweketango, ikhwalithi yesixhumi ihlobene ngokuqondile nokuthembeka kokusebenza nokuphepha kwalo lonke uhlelo lwamaketanga. Kungakhathaliseki ukuthi iketango lokuthutha elisindayo ezimayini noma izinhlobonhlobo zamaketanga okudlulisa, ukubaluleka kwekhwalithi yesixhumanisi sokuxhuma kuyabonakala ngokwakho Ngakho, ungahlulela kanjani ngokunembile ikhwalithi yeizixhumi zeketango?
Okokuqala, impahla iyitshe legumbi elinquma ikhwalithi yesixhumanisi.Izixhumi zekhwalithi ephezuluiningi lenziwe ngensimbi ye-alloy high-strength, lapho isilinganiso sezakhi ze-alloying sibalulekile. Ngokuhlaziywa kwe-spectral nezinye izindlela zobuchwepheshe, okuqukethwe kwezakhi ze-alloying kunganqunywa ngokunembile, futhi noma ngabe okokusebenza kusezingeni elifanele kungahlulelwa kuqala. Ngesikhathi esifanayo, ukuhlanzeka nokufana kwezinto ezibonakalayo akunakunakwa. Insimbi ehlanzekile enokungcola okumbalwa inganciphisa ingozi yokugxila ekucindezelekeni, futhi ngosizo lwe-microscope ye-metallographic ukuze ibuke i-microstructure, isigaba se-alloy esatshalaliswa ngokulinganayo siyinkomba ebalulekile yezixhumi zekhwalithi ephezulu, ezingaqinisekisa ukuthi zonke izingxenye zezixhumi zeketango zisebenza ndawonye lapho zicindezelwa ukugwema ukwehluleka kwendawo.
Inqubo yokukhiqiza iwukhiye wekhwalithi yezixhumi zamaketango. Ngokuphathelene nenqubo yokubumba, inqubo yokubumba enengqondo ingenza ukusabalalisa kwensimbi kuhlangabezane nezidingo zamandla esixhumanisi, futhi ukwelashwa kokushisa okungaphezulu njengobuchwepheshe be-carburizing kungathuthukisa ubulukhuni bobuso bezixhumi nokumelana nokugqoka. Phakathi kwamabhizinisi amaningi anikezelwe ekukhiqizeni izixhumi zeketango lezimayini,I-SCIC-AIDinokulawula okuqinile kanye nezinzuzo eziyingqayizivele kuzo zonke izici zokukhiqiza izixhumi zamaketango nethimba layo lokucwaninga nokuthuthukiswa kobuchwepheshe obuthuthukisiwe kanye neminyaka eminingi yesipiliyoni sembonini.
Mayelana nokukhethwa kwempahla, i-SCIC-AID isebenza nabahlinzeki bekhwalithi ephezulu ukuze kuqinisekiswe ukuthi izinto zokusetshenziswa zensimbi yengxubevange ziyahlangabezana noma zidlule ngisho namazinga emboni mayelana nenani le-alloying element, ubumsulwa kanye nokufana. Inqubo yokubumba yamukela imishini ethuthukisiwe kanye nesistimu yokulawula izinga lokushisa enembile, futhi ilandela ngokuqinile izidingo zokushisa zokuqala nezokugcina, okwenza ukusatshalaliswa kwensimbi kube okunengqondo futhi kuthuthukisa kakhulu amandla nokuthembeka kwezixhumi zeketango. Enqubweni yokwelapha ukushisela nokushisa, sethule okokusebenza okuhamba phambili emhlabeni kokuhlola nobuchwepheshe ukuze kuqashwe ikhwalithi yokushisela ngendlela ehlanganisa yonke indawo ukuze kuqinisekiswe ukuthi ukushisela ngakunye kuhlangabezana nezindinganiso eziphakeme, futhi ngesikhathi esifanayo kuthuthukisa amapharamitha wokwelapha ukushisa ukuze kuthuthukiswe ukusebenza okuphelele kwezixhumi.
Ngaphezu kwalokho, ukunemba kobukhulu kanye nekhwalithi yendawo akumele ithathwe kancane. Ukunemba kobukhulu bezixhumanisi zokuxhuma kuhlobene ngokuqondile nokunemba okuhambisanayo neketango lokuthutha, futhi ngesikhathi esifanayo, kuyadingeka ukuqinisekisa ukunemba okuhle komumo, njengokuyindilinga, flatness, njll., nokulinganisa ngokusebenzisa ama-calipers, ama-micrometers namanye amathuluzi wokulinganisa ukuqinisekisa usayizi onembile futhi ugweme amandla angalingani abangelwa ukulingana okungalungile. Ubuso kufanele busheleleke futhi bube bushelelezi, bungabi nemihuzuko ebonakalayo, ama-burrs kanye nemigodi, okungaba amaphuzu okugxilisa ukucindezeleka, kubangele ukuqhekeka noma kuthinte ukuqina kwelunga. Izixhumi zeketango lezimayini ze-SCIC-AID zinenani lezitifiketi zekhwalithi ezigunyaziwe, okubonisa ukuthi silandela ngokuqinile izindinganiso nezicaciso ezihlukahlukene enqubweni yokukhiqiza, okunikeza isiqinisekiso esiqinile sekhwalithi yomkhiqizo. Lapho kukhethwa isixhumi, lezi zici kufanele zicatshangelwe, ikakhulukazi emikhiqizweni ekhiqizwa izinkampani ezifana ne-SCIC-AID, ehamba phambili kuzo zonke izici, ukuze ikhwalithi yahlulelwe ngokunembe kakhudlwana, ukuze kukhethwe izixhumanisi ezithembekile zokuxhuma zohlelo lweketanga lokudlulisa ezimayini zamalahle ezinde kanye nokukhiqizwa kwezimboni, futhi uqinisekise ukusebenza okuphephile nokusebenza kahle kwemisebenzi yokukhiqiza.
