China OEM egcizelele ductile iron imikhiqizo castings byinqubo yokukhipha isikhunta sesihlabathifuthiCNC imishini.
I-Ductile cast iron, emele iqembu le-cast iron, ebizwa nangokuthi i-nodular iron, i-spheroidal graphite cast iron noma i-SG iron. I-nodular cast iron ithola i-nodular graphite ngokusebenzisa i-spheroidization kanye nokwelashwa kwe-inoculation, okuthuthukisa ngokuphumelelayo izakhiwo zemishini yensimbi ekhonjiwe, ikakhulukazi i-plasticity nokuqina, ukuze uthole amandla aphezulu kune-carbon steel.
I-Ductile iron ayiyona into eyodwa kodwa iyingxenye yeqoqo lezinto ezingakhiqizwa ukuze zibe nezinhlobonhlobo zezakhiwo ngokulawula i-microstructure. Isici esivamile esichazayo saleli qembu lezinto zokwakha ukuma kwegraphite. Kuma-ayina ama-ductile, i-graphite isesimweni samaqhuqhuva esikhundleni sama-flakes njengoba isensimbi empunga. Ukuma okucijile kwama-flakes e-graphite kudala amaphuzu okugxilisa ingcindezi ngaphakathi kwe-matrix yensimbi kanye nesimo esiyindilinga samaqhuqhuva sibe sincane kakhulu, ngaleyo ndlela kuvinjwe ukudalwa kwemifantu futhi kunikeze i-ductility ethuthukisiwe enikeza ingxubevange igama layo.
Insimbi eyi-nodular cast iron ithuthuke ngokushesha yaba insimbi eyinsimbi yesibili emva kwe-grey cast iron futhi isetshenziswa kabanzi. Okubizwa ngokuthi "insimbi efaka esikhundleni sensimbi" ikakhulukazi ibhekisela ku-iron ductile. I-Ductile iron ivame ukusetshenziselwa ukukhiqiza izingxenye zama-crankshafts nama-camshaft ezimoto, ogandaganda, nezinjini ezivuthayo zangaphakathi, kanye nama-valve anomfutho omaphakathi wemishini ejwayelekile.
Esigabeni sokuklama semikhiqizo yokusakazwa kwe-iron ductile, ithimba lephrojekthi ekhethekile kufanele limiswe ukuze liqhube "Imodi Yokuhluleka Kwedizayini kanye Nokuhlaziywa Kwemiphumela" (DFMEA). Ithimba lephrojekthi ngokuvamile liqukethe abaklami bemikhiqizo, abaklami bezinqubo zokulingisa, nezingcweti zokuvikela imvelo. Okuqukethwe okuyinhloko kokuhlaziywa kwe-DFMEA kufanele kubandakanye ukuthi ingabe izidingo zekhwalithi yokulingisa yengxenye yesakhiwo, inqubo yokulingisa yesakhiwo sokulingisa, kanye nenqubo yokulingisa yezidingo zokuvikela imvelo konke kuyahlangatshezwana nayo.
Izici Zokusebenza Ze-Ductile Iron Castings:
• Uketshezi kanye nokushwabana komugqa we-iron ductile kusondele kakhulu kulokho okusansimbi empunga
• Ukuthambekela kokuncipha kwevolumu kanye nokwakheka kokucindezeleka kwangaphakathi kukhulu kune-grey cast iron, ejwayele ukuncipha kanye nokuqhekeka.
• Amandla, ipulasitiki, kanye ne-elastic modulus ye-ductile iron mikhulu kunaleyo ye-grey cast iron, futhi imelana kahle nokuhuzuka.
• Ukumuncwa ukushaqeka kubi kune-iron empunga
Izici Zesakhiwo Se-Ductile Iron Castings:
• Ngokuvamile yakhelwe ukuba iyunifomu odongeni ukushuba, futhi zama ingxenye ewugqinsi kufanele kugwenywe uma kungenzeka
• Ezingxenyeni ezithile eziwugqinsi nezinkulu, isakhiwo esingenalutho noma isakhiwo esinezimbambo eziqinisiwe kufanele kwamukelwe
Izinzuzo Zenqubo Yokusakaza Isihlabathi:
• Izindleko Eziphansi ngenxa yezinto zayo zokubumba ezishibhile nezikwazi ukugaywa kabusha kanye nemishini yokukhiqiza elula.
• Uhlu olubanzi lwesisindo seyunithi kusuka ku-0.10 kg kuya ku-500 kgs noma ngaphezulu.
• Isakhiwo Esihlukahlukene kusuka ohlotsheni olulula kuya ohlotsheni oluyinkimbinkimbi.
• Ifanele izidingo zokukhiqiza zobuningi obuhlukahlukene.
