China OEM tsika ductile kukanda simbi castings kubudikidzayakarasika wax investment kukanda muitiro. Ductile iron, inozivikanwawo sekuti ducitle cast iron, nodular iron, spheroidal graphite iron, spheroidal graphite cast iron, kana kungoti SG iron kwenguva pfupi.Kana graphite iripo sediki, denderedzwa, uye yakagovaniswa zvidimbu, kushaya simba kwayo idiki uye simbi dzakakandwa dzakadaro dzinenge dziine ductility yakakwirira. Iri rudzi rwesimbi yakakandwa inonzi ductile kana nodular iron kana spheroidal graphite kana kungoti SG iron. Iyi fomu yegraphite inogona kuwanikwa nekuwedzera elemental magnesium kana cerium kana musanganiswa wezvinhu zviviri izvi kusimbi yakanyungudutswa. Magnesium inowedzerwa muhuwandu hwe0.07 kusvika 0. 10% inoteverwa nekuwedzera kweferro-silicon kukurudzira graphitization. Munguva yekusimba, magnesium inobatsira mukugovera graphite mukati mesimbi yese.
Ductile iron ine zvirinani simba-ku-huremu reshiyo, zvirinani machinability uye yakakwirira kukanganisa kukosha. Uyezve, iyo ductile iron zvikamu zvinogadzirwa nekukanda maitiro umo kudzora kurinani kwechikamu chimiro kunogona kuwanikwa kana ichienzaniswa nekudonha kwekugadzira. Nekudaro, zvakawanda zvinoumba senge crank shafts uye machira ekubatanidza anogadzirwa kazhinji nekudonhedza madonhwe ari kuwedzera kutsiviwa ne ductile iron castings.
