Njengengxenye ebalulekile yokuxhumeka kweketanga, ikhwalithi yesixhumi ihlobene ngqo nokuthembeka kokusebenza kanye nokuphepha kohlelo lonke lweketanga. Kungakhathaliseki ukuthi kuyiketanga elithwala umthwalo osindayo ekumbeni noma ezinhlobonhlobo zeketanga lokudlulisa, ukubaluleka kwekhwalithi yesixhumanisi esixhumanisayo kuyabonakala. Ngakho-ke, ungahlulela kanjani ngokunembile ikhwalithi yeketangaizixhumi zeketanga?
Okokuqala, izinto zokwakha ziyitshe lesisekelo elinquma ikhwalithi yesixhumanisi.Izixhumi zekhwalithi ephezuluNgokuvamile zenziwe ngensimbi ye-alloy enamandla amakhulu, lapho isilinganiso sezinto ezixubayo sibalulekile khona. Ngokuhlaziywa kwe-spectral kanye nezinye izindlela zobuchwepheshe, okuqukethwe kwezinto ezixubayo kunganqunywa ngokunembile, nokuthi ngabe izinto zisezingeni elifanele yini kungahlulelwa kusengaphambili. Ngesikhathi esifanayo, ubumsulwa kanye nokufana kwezinto akunakwa. Insimbi ehlanzekile kakhulu enokungcola okuncane inganciphisa ingozi yokuxineka, futhi ngosizo lwe-microscope ye-metallographic ukuze kubonwe isakhiwo esincane, isigaba se-alloy esatshalaliswa ngokulinganayo siyisibonakaliso esibalulekile sezixhumi zekhwalithi ephezulu, ezingaqinisekisa ukuthi zonke izingxenye zezixhumi zeketanga zisebenza ndawonye lapho zicindezelwe ukuze kugwenywe ukwehluleka kwendawo.
Inqubo yokukhiqiza ibalulekile ekhwalithini yezixhumi zeketanga. Ngokuphathelene nenqubo yokufaka, inqubo yokufaka efanele ingenza ukusatshalaliswa kwensimbi kube lula ukuhlangabezana nezidingo zamandla zeketanga, futhi ukwelashwa kokushisa komhlaba njengobuchwepheshe be-carburizing kungathuthukisa ubulukhuni bomphezulu wezixhumi kanye nokumelana nokuguguleka. Phakathi kwamabhizinisi amaningi azinikele ekukhiqizeni izixhumi zeketanga lezimayini,Usizo lwe-SCICinelawulo oluqinile kanye nezinzuzo eziyingqayizivele kuzo zonke izici zokukhiqiza izixhumi zeketanga ngethimba layo locwaningo nokuthuthukiswa kobuchwepheshe obuthuthukisiwe kanye neminyaka eminingi yesipiliyoni embonini.
Ngokuphathelene nokukhethwa kwezinto, i-SCIC-AID isebenzisana nabahlinzeki bekhwalithi ephezulu ukuqinisekisa ukuthi izinto zokusetshenziswa zensimbi ye-alloy ezisetshenziswayo ziyahlangabezana noma zidlule amazinga embonini ngokwesilinganiso se-alloying element, ubumsulwa kanye nokufana. Inqubo yokwakha isebenzisa imishini ethuthukisiwe kanye nohlelo lokulawula izinga lokushisa olunembile, futhi ilandela ngokuqinile izidingo zokushisa zokuqala nezokugcina, okwenza insimbi ilulaze ukusatshalaliswa okunengqondo futhi ithuthukise kakhulu amandla nokuthembeka kwezixhumi zeketanga. Enqubweni yokushisela nokwelapha ukushisa, sethule imishini yokuhlola ehamba phambili emhlabeni kanye nobuchwepheshe bokuqapha ikhwalithi ye-weld ngendlela ephelele ukuqinisekisa ukuthi i-weld ngayinye ihlangabezana nezindinganiso eziphakeme, futhi ngesikhathi esifanayo sithuthukise amapharamitha okwelapha ukushisa ukuze sithuthukise ukusebenza okuphelele kwezixhumi.
Ngaphezu kwalokho, ukunemba kobukhulu kanye nekhwalithi yobuso nakho akufanele kuthathwe kancane. Ukunemba kobukhulu bezixhumanisi ezixhumanisayo kuhlobene ngqo nokunemba okufana nochungechunge lokuhambisa, futhi ngesikhathi esifanayo, kuyadingeka ukuqinisekisa ukunemba kwesimo esihle, njengokuyindilinga, ukuba yisicaba, njll., kanye nokulinganisa ngama-caliper, ama-micrometer kanye namanye amathuluzi okulinganisa ukuqinisekisa usayizi onembile nokugwema amandla angalingani abangelwa ukungalingani kahle. Ubuso kufanele bube bushelelezi futhi bube yisicaba, bungabi nemihuzuko ebonakalayo, ama-burrs kanye nemigodi, okungaba izindawo zokugxila ekucindezelekeni, kubangele imifantu noma kuthinte ukuqina kwejoyinti. Izixhumi zeketanga lezimayini ze-SCIC-AID zinezitifiketi eziningi zekhwalithi ezigunyaziwe, okubonisa ukuthi silandela ngokuqinile amazinga ahlukahlukene kanye nemininingwane enqubweni yokukhiqiza, enikeza isiqinisekiso esinamandla sekhwalithi yomkhiqizo. Uma ukhetha isixhumi, lezi zici kufanele zicatshangelwe, ikakhulukazi emikhiqizweni ekhiqizwa izinkampani ezifana ne-SCIC-AID, ezinhle kakhulu kuzo zonke izici, ukuze ikhwalithi ikwazi ukwahlulelwa ngokunembile, ukuze kukhethwe izixhumanisi zokuxhuma ezinokwethenjelwa zesistimu yokudlulisa uchungechunge ezimayini zamalahle ezindongeni kanye nokukhiqizwa kwezimboni, futhi kuqinisekiswe ukusebenza okuphephile nokusebenza kahle kwemisebenzi yokukhiqiza.
