Nkedo nkedo nke igwe eji eme ihe

OEM omenala ductile nkedo ígwè nwereusoro nkedo itinye egositere na ụlọ ọrụ nkedo China. Anyị nwekwara ike ịnye ọrụ nkeCNC igwe, mgbakọ na ọgwụgwọ elu.

Igwe ihe nkedo bụ alloys ferrous nke nwere ọdịnaya carbon karịa 2%. Ọ bụ ezie na nkedo ígwè nwere ike ịnwe pasent carbon n'etiti 2 ruo 6.67, njedebe bara uru na-adịkarị n'etiti 2 na 4%. Ndị a dị mkpa karịsịa n'ihi àgwà nkedo ha mara mma. Ihe nkedo isi awọ na ígwè nkedo ductile (nke a na-akpọkwa ígwè nkedo nodular ma ọ bụ spheroidal graphite iron) bụ ihe a na-ejikarị eme ihe na ya.ebe a na-emepụta ihe nkedo.

Ihe nkedo nke ductile bụ ígwè nodularized nke graphite dị ka obere, gburugburu, na nkesa nke ọma, mmetụta ya na-adịghị ike dị ntakịrị na nkedo ndị dị otú ahụ ga-enwe ductility dị elu. Ụdị nkedo a ka a na-akpọ ductile ma ọ bụ nodular iron ma ọ bụ spheroidal graphite ma ọ bụ nanị SG iron. Enwere ike nweta ụdị graphite a site n'ịgbakwunye magnesium elemental ma ọ bụ cerium ma ọ bụ ngwakọta nke ihe abụọ ahụ iji gbazee ígwè. A na-agbakwunye Magnesium n'ogo 0.07 ruo 0. 10% na-esote mgbakwunye ferro-silicon iji kwalite graphitization. N'oge siri ike, magnesium na-enyere aka na nkesa graphite na metal.

Iron ductile nwere oke ike na ịdị arọ ka mma, nrụpụta ka mma yana uru mmetụta dị elu. Ọzọkwa, a na-emepụta ihe nkedo ígwè ductile site na usoro nkedo ebe enwere ike nweta njikwa kacha mma nke ọdịdị akụrụngwa ma e jiri ya tụnyere ntube.
