Ductile Cast Iron Investment Casting

OEM tsika ductile cast iron castings neinvestment casting processkubva kuChina casting kambani. Tinogonawo kupa masevhisi eCNC machining, kusangana uye kurapwa kwepamusoro.

Cast irons ndiwo maferrous alloys ane carbon content inopfuura 2%. Kunyangwe simbi dzakakandwa dzinogona kuva nekabhoni muzana pakati pe2 kusvika 6.67, muganho unoshanda unowanzo pakati pe2 ne4%. Izvi zvakakosha zvakanyanya nekuda kwehunhu hwavo hwekukanda hwakanakisa. Iyo grey cast irons uye ductile cast irons (inonziwo nodular cast iron kana spheroidal graphite iron) ndiyo inonyanya kushandiswacasting foundry.

Iyo ductile cast iron is nodularized iron iyo graphite iripo sediki, denderedzwa, uye yakagovaniswa zvimedu, kushaya simba kwayo idiki uye simbi dzakakandwa dzakadaro dzinenge dzakakwirira ductility. 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 castings inogadzirwa nekukanda maitiro umo kudzora kurinani kwechikamu chimiro kunogona kuwanikwa kana ichienzaniswa nekudonha kwekugadzira. Nekudaro, zvakawanda zvinoumba senge crank shafts uye yekubatanidza tsvimbo inogadzirwa kazhinji nekudonhedza forging ndeyeinowedzera kutsiviwa ne ductile iron castings.
