| Okubalulekile | Izici Nezicelo |
| Grey cast iron | I-fluidity enhle, izinga lokushwabana elincane ngesikhathi sokupholisa, amandla aphansi, ipulasitiki kanye nokuqina, i-elastic modulus iyahlukahluka phakathi kuka-80000 ~ 140000MPa ngama-microstructures ahlukene, amandla okucindezela aphakeme izikhathi ezi-3 ~ 4 kunamandla aqinile, ukumelana nokugqokaukusebenza kanye nokumuncwa kokudlidliza.Ayizwani nokusikeka futhi inokusebenza okuhle kokusika.Ukusebenza kwe-welding kubi.Awukwazi ukusetshenziswa isikhathi eside ngaphezu kuka-300 ~ 400℃.85% ~ 90% izinga lemikhiqizo yensimbi ekhonjiwe. |
| Minsimbi ekhonjiwe | Ukusebenza kokulingisa kubi kakhulu kunokwensimbi empunga futhi kungcono kunokwensimbi.Isetshenziselwa ukukhiqiza ama-casting amancane anezindonga ezincane ezinezidingo ezithile zamandla nokuqina.Ukumelana nokugqwala okuhle nokusebenza okuhle kokucubungula.Ukuqina komthelela bukhulu ngokuphindwe izikhathi ezingu-3 ~ 4 kunokwensimbi empunga. |
| I-Ductile Iron | Ukusebenza kokulingisa kubi kakhulu kunokwensimbi empunga, futhi kujwayele ukuba namaphutha.Ukusebenza kokusika kuhle, futhi ukwelashwa kokushisa kungenza ukusebenza kwayo kushintshe ebangeni elibanzi.Amandla aqinile aphakeme kunalawo ensimbi esansimbi kanye nensimbi ecijile, futhi isilinganiso samandla esivuno kumandla aqinile singaphezu kwensimbi nensimbi ethambile ethambile.I-plasticity iyona engcono kunazo zonke ku-cast iron, futhi ukuqina komthelela akuwona kuhle njengokwensimbi, kodwa kukhulu kakhulu kunokwensimbi empunga.Inokusebenza okuhle kwezinga lokushisa eliphansi.Amandla okukhathala aphakeme, asondele ku-45 steel, kodwa ukuzwela ekugxilweni kwengcindezi kuphansi kunaleyo yensimbi.Ukumelana nokugqoka okuhle, ukumelana nokushisa nokumelana nokugqwala.Isilinganiso sokudlidliza sensimbi, i-ductile iron ne-grey iron ngu-1:1.8:4.3.esetshenziswa kabanzi njengezingxenye ezibalulekile. |
| I-Graphite Iron Ehlanganisiwe | Izakhiwo zemishini ye-vermicular graphite cast iron ziphakathi kwe-grey cast iron ne-ductile iron, futhi inokubumbana okuhle, ukumelana nokushisa nokumelana nokugqoka.Ukusebenza kwayo kokulingisa kungcono kunokwensimbi eyi-ductile futhi kusondele ku-grey cast iron.Amandla ayo afana nensimbi ye-ductile, futhi ine-anti-vibration efanayo, i-thermal conductivity kanye nezakhiwo zokuphonsa ku-grey iron, kodwa i-plasticity engcono nokumelana nokukhathala kune-grey iron.I-graphite cast iron ehlanganisiwe nakanjani izoqukatha inani elithile le-nodular graphite.Ukwanda kwe-graphite ye-nodular kuzokwandisa amandla ayo kanye nokuqina, kodwa ngezindleko zokuphazamisa ikhono lokubunjwa kwensimbi encibilikisiwe kanye nokuwohloka kokusebenza nokusebenza okushisayo kwe-castings. |
| insimbi | Ukusebenza kokulingisa kubi kakhulu, uketshezi olumanzi luphansi, futhi ukushwabana kukhulu, kodwa kunezinto eziphakeme eziphelele zemishini, okungukuthi, amandla aphakeme, ukuqina kanye nepulasitiki.Amandla aqinile namandla acindezelayo acishe alingane.Ezinye izinsimbi ezikhethekile zensimbi zinezakhiwo ezikhethekile ezifana nokumelana nokushisa nokumelana nokugqwala |
| Faka ingxube ye-aluminium | Ama-alloys e-aluminium angu-1/3 kuphela ukuminyana kwensimbi futhi asetshenziselwa ukwenza izakhiwo zokukhanya ezihlukahlukene.Amanye ama-alloys e-aluminium angaqiniswa ukwelashwa kokushisa ukuze abenze babe nezakhiwo ezihlanganisa kangcono.Njengoba ubukhulu bodonga bukhula, amandla ayancipha kakhulu. |
| ithusi elikhanyisiwe | Ihlukaniswe izigaba ezimbili: i-tin bronze ne-Wuxi bronze.Ithusi eliwuthayela linokuguga okuhle nokumelana nokugqwala, amandla aphezulu nobulukhuni, ukusebenza kabi kokulingisa, futhi lijwayele ukuhlukaniswa nokuncipha.Ukucisha akunawo umthelela oqinisayo.I-Wuxi bronze ivamise ukusetshenziswa kwi-aluminium bronze noma i-lead bronze, engasebenzi kahle ekubumbeni.I-Aluminium bronze inamandla aphezulu, ukumelana nokugqoka kanye nokumelana nokugqwala.I-bronze eholayo inamandla amakhulu okukhathala, amandla okushisa aqinile kanye nokumelana ne-asidi |
| I-Cast Brass | Ukuncipha okukhulu, amandla aphakeme ngokuvamile, ipulasitiki enhle, ukumelana nokugqwala okuhle nokumelana nokuguga.Ukusebenza okuhle kokusika |
