Kenyelletso e Khutšoanyane:
DUctile iron, eo hape e tsejoang e le ductile cast iron, nodular cast iron, spherical graphite iron, spherical graphite cast iron and SG iron, ke mofuta oa tšepe e entsoeng ka graphite e ngata e fumanoeng ka 1943 ke Keith Millis.Le hoja mefuta e mengata ea tšepe ea tšepe e fokola ka tsitsipano le brittle, tšepe ea ductile e na le tšusumetso e ngata le ho hanyetsa mokhathala, ka lebaka la ho kenngoa ha eona ka nodular graphite.Tšepe ea ductile hase ntho e le 'ngoe empa ke karolo ea sehlopha sa lisebelisoa tse ka hlahisoang ka mefuta e mengata ea thepa ka ho laola microstructure ea bona.Tšobotsi e tloaelehileng e hlalosang sehlopha sena sa lisebelisoa ke sebōpeho sa graphite.Liaeneng tsa ductile, graphite e ka sebopeho sa maqhutsu ho fapana le li-flakes joalo ka tšepe e putsoa.Le hoja li-graphite flakes li etsa hore ho be le khatello ea kelello ka har'a matrix ea tšepe, li-nodule tse chitja li thibela ho thehoa ha mapetsong, kahoo li fana ka ductility e ntlafetseng e fanang ka lebitso la alloy.
Austempered ductile iron (ADI; ke hore, austenite tempered[7]) e ile ea sibolloa ka bo-1950 empa e ile ea rekisoa 'me ea atleha lilemo tse seng kae hamorao.Ka ADI, mohaho oa metallurgical o sebelisoa ka mokhoa o rarahaneng oa ho phekola mocheso.

HONGDA Ductile iron castings:
Mathoasong a 2021, HONGDA e ile ea haha fektheri e ncha ho hlahisa lisebelisoa le mohala oa tlhahiso bakeng sa Ductile Iron casting.
1. Boitsebiso: QT450#-10 le sekhahla sa Spheroidization se feta boemo ba III ho fumana boleng bo botle ba ho bapala ho tšehetsa kopo ea hau.
2. Mohala oa tlhahiso o ikemetseng ho fihlela katleho e phahameng le tlhahiso e kholo ea bokhoni, 550T / Khoeli, ho khutlisetsa tlhoko ea hau e potlakileng.
3. Likopo: li-ductile iron castings bakeng sa molala, bracket e sa sebetseng joalo ka likarolo tse ka hare ho 70KGS. Joalo ka lebaka la boits'oaro ba rona le tlhokomeliso ea ho lokisa, khoebo ea rona e hapile botumo bo holimo har'a bareki hohle tikolohong bakeng sa Factory e rekisoang ka ho chesa. China Cat Bulldozer Single Flange Roller HD400 HD450 Track Roller, Our Enterprise Core Principle: Ea pele ea botumo ;Tiisetso e tloaelehileng ; moreki o phahame.
Fektheri e rekisoang haholoChina Track Roller, Karolo ea Undercarriage, Khotsofalo ea bareki ke sepheo sa rona sa pele.Maikemisetso a rona ke ho hahamalla boleng bo phahameng ka ho fetesisa, ho hatela pele khafetsa.Re u amohela ka tieo ho hatela pele ka letsoho le rona, le ho aha bokamoso bo atlehileng hammoho.
