Ingcindezi eyinsalela ngaphakathiizinsimbi zensimbikuyinkinga ebalulekile engathinta ukusebenza nokuphila isikhathi eside kwezingxenye zensimbi. Ukubikezela nokuphatha lokhu kucindezeleka kubalulekile ekuqinisekiseni ikhwalithi nokuqina komkhiqizo wokugcina.
Ukubikezela Kokucindezeleka Okusalela Ekusakazeni
Ingcindezi eyinsalela ekulingiseni ingabikezelwa kusetshenziswa izindlela zokubala ezifana nokuhlaziywa kwesici esilinganiselwe (FEA). Lezi zifaniso zicabangela izinqubo ezishisayo nezomshini ngesikhathi sokusakaza, okuhlanganisa ukuqiniswa nokupholisa.
Ukunciphisa Ukwakhiwa Kokucindezeleka Okusele
Ukunciphisa ukwakheka kwengcindezi eyinsalela ekubunjweni, izindlela eziningi zingasetshenziswa. Ukupholisa okulawulwayo kuyindlela eyodwa, lapho ukulingisa kupholiswa ngezinga elifanayo ukuze kuvinjelwe ukufinyela okuhlukile. Ukuthuthukisa idizayini yokulingisa ukuze ugweme amakhona acijile nezingxenye eziwugqinsi nakho kungasiza, njengoba lezi zindawo zithambekele ekugxilweni kwengcindezi ephezulu. Ukwengeza, ukulungisa ukwakheka kwe-alloy ukuze kufinyelele ukuqina okufanayo kunganciphisa ukucindezeleka.
Ukutholwa Kwe-Residual Stress
Ukuthola ingcindezi eyinsalela ekulingiseni kungafinyelelwa ngezindlela zokuhlola ezingezona ezonakalisayo. I-X-ray diffraction (XRD) iyindlela evamile ekala ukuhlukana kwezindiza zekristalu kundaba ukuze kunqunywe isimo sokucindezeleka. Ukuhlolwa kwe-Ultrasonic nakho kungasetshenziswa ukuthola izinguquko ezimpahleni ezibonakalayo ezibonisa ingcindezi. Amageji e-strain angasetshenziswa ukukala i-surface strains ngokuqondile.
Ukunciphisa Ingcindezi Ku-Cast Iron Castings
Ukuze kuqedwe ukucindezeleka okusele kuInsimbi, i-annealing iyindlela esetshenziswa kakhulu. Lokhu kuhlanganisa ukushisisa ukusakaza ezingeni lokushisa elingaphansi kwendawo yakho yokuncibilika, ukuyibamba kulelo zinga lokushisa ukuze uvumele ukunethezeka kwengcindezi, bese ukupholisa kancane. Le nqubo ivumela ukucindezelwa kwangaphakathi ukuthi kukhululeke ngaphandle kokushintsha kakhulu izakhiwo zentokozo.
Ukunciphisa Ingcindezi Ekufakweni Kwensimbi
Ngobasteel utshalomali castings, ukwehlisa ukucindezeleka kuyasebenza futhi. Le nqubo ifana naleyo yensimbi ekhonjiwe, kodwa amazinga okushisa ahilelekile ngokuvamile aphezulu ngenxa yezakhiwo ezishisayo ezihlukene zensimbi. Ukushisisa okulawulwayo nokupholisa kubalulekile ukuze kuvinjelwe ukwethulwa kokucindezeleka okusha phakathi nenqubo.
Ukunciphisa Ingcindezi Ekusakazeni Kwengxubevange Engeyona Insimbi
Ama-alloys angewona ayoni, njenge-aluminium nama-alloys ethusi, nawo adinga ukukhululeka kwengcindezi ukuze athuthukise ukusebenza kwawo. Lezi zinto ngokuvamile zikhulula ingcindezi ngokusebenzisa izindlela ezishisayo ezifana nensimbi eyinsimbi kodwa ngokuvamile emazingeni okushisa aphansi. Ukwengeza, amanye ama-alloys angewona ayoni angazuza kumasu okusebenza okusiza ukucindezeleka, okufana nokudlidliza kwengcindezi, esebenzisa ukudlidliza komshini ukuze kwabiwe kabusha futhi kudambise ukucindezeleka kwangaphakathi.
