Ntchito zosiyanasiyana
Ndi mawonekedwe ake abwino kwambiri komanso zabwino zake zachuma,ductile ironpang'onopang'ono ikukhala chinthu chosankhidwa m'mafakitale ambiri, m'malo ambiri m'malo mwa zinthu zakale monga zitsulo zonyezimira, zitsulo zosindikizidwa, ma weldments, chitsulo chosungunuka,chitsulo chotuwandi chitsulo chachitsulo. Ku United States, zimenezi n’zoonekeratu. Chitsulo chachitsulo chatenga gawo lofunika kwambiri pamsika ndipo chasintha bwino magawo osiyanasiyana azinthu zomwe tazitchula pamwambapa, kuwonetsa kuthekera kwake kogwiritsa ntchito kosayerekezeka komanso mpikisano wamsika.

Kusanthula kapangidwe kazinthu
Kuchokera pamawonekedwe opangira, kupanga chitsulo cha ductile kumayang'aniridwa ndi matrix a ferrite, omwe amawerengera 60% yazotulutsa zonse, pomwe matrix a pearlite amatsata kumbuyo kwambiri ndipo amakhala ndi malo. Kuphatikiza apo, matrix osakanikirana a ferrite ndi pearlite amawerengeranso gawo lalikulu. Zitatuzi pamodzi zimapanga pafupifupi 95% ya zitsulo zonse zopangidwa ndi ductile iron, zomwe zimasonyeza malo akuluakulu a matrices awiriwa pakupanga chitsulo cha ductile.
Kusanthula kwamakina kwabwino kwambiri
Chifukwa chachikulu chomwe chitsulo cha ductile chimatha kuwoneka bwino pakati pa zinthu zambiri ndizomwe zimapangidwira. Ilibe zokolola mwanjira yanthawi zonse, ndipo piritsi la kupsyinjika likuwonetsa mayendedwe opitilira muyeso kuposa malire. Khalidwe limeneli limachokera ku khalidwe lapadera la mipira ya graphite pansi pa kupsinjika maganizo: pamene kupanikizika kumapitirira malire otanuka, ngakhale kuti mipira ya graphite ikuwoneka ngati mbali ya masanjidwewo, iwo salinso opunduka, kupanga mipata mu njira yotalikirapo, zomwe zimabweretsa kuwonjezeka kwa voliyumu. , ndipo kukulitsa uku sikungathe Kulipiridwa ndi kuponderezana kozungulira.
Kuyerekeza kwa magwiridwe antchito ndi zida zina
Chitsulo cha Gray cast: Pachikhalidwe, mphamvu yokhazikika yokha ndiyomwe imagwiritsidwa ntchito ngati chizindikiritso cha magwiridwe antchito, ndipo giredi yapamwamba imakhala ndi mphamvu zocheperako (350 MPa zokha). Mosiyana ndi zimenezi, chitsulo cha ductile chimasonyeza ubwino waukulu mu mphamvu ndi pulasitiki.
Chitsulo chosungunuka: Ngakhale chili ndi zizindikiro za pulasitiki, kaya ndi yakuda-core, pearlite kapena white-core malleable iron, makina ake osakanikirana sali abwino ngati chitsulo cha ductile.
Chitsulo choponyedwa ndi chitsulo chomangika: Ngakhale chimagwira ntchito bwino pakutalikirana kwapambuyo pakuthyoka komanso kulimba kwamphamvu, kulimba kwa zokolola sikofanana ndi chitsulo cha ductile, kuwonetsanso kupambana kwa chitsulo cha ductile mu ntchito zinazake.
