Kayayyaki, Fa'idodi da Aikace-aikacen Iron Ductile

Iron Ductile, wanda kuma aka sani da spheroidal ko nodular iron, rukuni ne na ƙarfe na baƙin ƙarfe tare da ƙananan ƙananan ƙwayoyin cuta wanda ke ba su ƙarfin ƙarfi, sassauci, karko, da elasticity. Ya ƙunshi fiye da kashi 3 cikin dari na carbon kuma ana iya lanƙwasa, murɗawa, ko gurɓatacce ba tare da karye ba, godiya ga tsarin flake ɗin sa na graphite. Ƙarfe mai ɗumbin yawa yana kama da ƙarfe a cikin kayan aikin injinsa kuma ya fi ƙarfi fiye da daidaitaccen simintin ƙarfe.

Ana ƙirƙira simintin ƙarfe na ƙarfe ta hanyar zuba narkakkar baƙin ƙarfe a cikin gyaggyarawa, inda ƙarfen ya yi sanyi da ƙarfi don samar da sifofin da ake so. Wannan aikin simintin yana haifar da ƙaƙƙarfan abubuwa na ƙarfe tare da kyakkyawan karko.

Me Ya Sa Ductile Iron Ya Keɓanta?

An ƙirƙira ƙarfen ƙarfe a cikin 1943 a matsayin haɓaka na zamani akan simintin ƙarfe na gargajiya. Ba kamar simintin ƙarfe ba, inda graphite ya bayyana a matsayin flakes, ductile iron yana da graphite a cikin nau'in spheroids, saboda haka kalmar "spheroidal graphite." Wannan tsarin yana ba da damar ƙarfe na ductile don jure lankwasa da girgiza ba tare da tsagewa ba, yana ba da ƙarfin juriya fiye da simintin gyare-gyare na gargajiya, wanda ke da haɗari ga raguwa da karaya.

An yi ƙarfen ƙarfe da farko daga ƙarfen alade, ƙarfe mai tsafta mai tsafta mai sama da kashi 90% na baƙin ƙarfe. An fi son baƙin ƙarfe na alade saboda yana da ƙarancin ragowar abubuwa ko abubuwa masu cutarwa, daidaitaccen sinadarai, kuma yana haɓaka mafi kyawun yanayin slag yayin samarwa. Wannan kayan tushen shine babban dalilin da ya sa ductile iron foundries fi son alade baƙin ƙarfe a kan sauran kafofin kamar guntun karfe.

Abubuwan Abubuwan Iron Ductile

Ana ƙirƙira maki daban-daban na baƙin ƙarfe ductile ta hanyar sarrafa tsarin matrix a kusa da graphite yayin simintin gyare-gyare ko ta ƙarin jiyya na zafi. Waɗannan ƙananan bambance-bambancen bambance-bambance an tsara su don cimma ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙaƙƙarfan ƙarfe, wanda hakanan ke tantance kaddarorin kowane nau'in ƙarfe na ductile.

Ana iya tunanin ƙarfen ƙarfe a matsayin karfe tare da spheroids masu zane-zane. Halayen matrix na ƙarfe da ke kewaye da spheroids na graphite suna da tasiri sosai ga kaddarorin ƙarfe na ductile, yayin da graphite kanta ke ba da gudummawa ga elasticity da sassauci.

Akwai nau'ikan matrices da yawa a cikin baƙin ƙarfe na ductile, tare da waɗannan su ne mafi yawanci:

1. 1. Ferrite- Matrix ƙarfe mai tsafta wanda yake da ductile sosai kuma mai sassauƙa, amma yana da ƙarancin ƙarfi. Ferrite yana da juriya mara kyau, amma juriya mai girman tasirinsa da sauƙi na machining ya sa ya zama muhimmin abu a cikin maki ductile baƙin ƙarfe.
2. 2. Pearlite- Kundin na ferrite da iron carbide (Fe3C). Yana da matukar wahala tare da matsakaicin ductility, yana ba da ƙarfi mai ƙarfi, juriya mai kyau, da juriya mai matsakaicin tasiri. Har ila yau, Pearlite yana samar da kayan aiki mai kyau.
3. 3. Pearlite/Ferrite- Tsarin gauraye tare da duka pearlite da ferrite, wanda shine mafi yawan matrix a cikin maki na kasuwanci na ƙarfe ductile. Ya haɗu da halaye na duka biyu, samar da daidaitaccen tsarin kula da ƙarfi, ductility, da machinability.
