Bead- ungweru wa frey wa grey wakupangika na chisulo
Grey cast iron ni mtundu wa iron cast. Carbon ilipo mu vitsulo vya visulo pa graphite ya sheet. Mulomo wakuphyoka ni wa grey. Muŵe na kuponya makora, kudumura, kuseŵera makora. Pakupanga ma rack, mabokosi, na vinyake. Grey cast iron graphite ni pepala, malo ghawemi ghakunyamulira ni ghachoko waka, nsonga ya graphite njambura kusuzga kupanga mtundu wa kusuzgika maghanoghano, ntheura nkhongono, pulasitiki na kukhora kwa chisulo cha grey cast ni vichoko kuluska vya chitsulo chinyake cha cast. Kweni, ili na kugwedezeka makora, kugwedezeka kwa notch kwakucepa ndiposo kukana vyakuvwara vyapachanya.
Grey cast iron ili na carbon yinandi (2.7% ~ 4.0%), iyo yingawoneka nga ni matrix ya chisulo cha carbon na graphite ya sheet. Malinga na wupu wa matrix wakupambanapambana wa mtundu wa mtundu wa grey wakugaŵika mu vigaŵa vitatu: chisulo cha iron grey cast iron; nga ni chitsulo cha matrix cha ngale cha nga ni chitsulo cha grey; nga ni chitsulo cha matrix matrix grey.
Pearl {{0} frey iron yili mu mkanda na ferrite matrix wakusakanizgika, kugaŵika na pepala la graphite lakukhola, nkhongono na kukhora kwa chisulo ichi ni vichoko kuluska vyakwamba, kweni vikukwaniska kukwaniska ivyo thupi la ŵanthu wose, likupangika, kugwedezeka kwake, ndipo nchakusuzga yayi kusungunuka, ndicho chitsulo cha mtundu wa grey icho chikugwiriskirika nchito chomene.
Tizirombo tuchokotuchoko uto tukuŵa na chisulo cha grey ni mtundu wakupambanapambana wa carbon uwo uli mu chisulo. carbon iyo yili mu iron ya grey yikupangika na carbon wakusazgikana (Fe3C) na carbon ya graphite. Para carbon wakusazgika ni 0.8%, ni chisulo cha mtundu wa grey; para carbon wakusazgikana ni pasi pa 0.8%, ni chitsulo cha grey cha ferrite; para carbon yose yili mu graphic, ni chisulo cha grey.
Katundu wa makina wa iron wa grey wakupangika na gulu la matrix na kawonekero ka graphite. The sheet graphite mu iron ya grey yikupatula chomene matrix, iyo njambura kusuzga kupangiska kuti munthu waŵe na suzgo la kusuzgika maghanoghano pa nsonga ya graphite Angle, mwakuti nkhongono ya tensile, pulasitiki na kukhora kwa chisulo cha grey cast ni pasi chomene kuluska vya chisulo, kweni nkhongono yakukhozga yikuyana na iyo ya chisulo, ndiposo ni chitsulo chakupangika na chitsulo chakupangika chomene mu chitsulo icho chikugwiriskirika nchito chomene. Pa nyengo yeneyiyo, viwaro vya matrix navyo vikukhwaska chomene katundu wa makina wa iron cast iron. Pepala la graphite la chisulo cha grey lili lakukhora ndipo graphite sheet ya matrix yili na nkhongono zinandi na kukhora, ndipo yikugwiriskirika nchito chomene pakupanga vithuzithuzi vyakuzirwa; graphite sheet ya chisulo cha grey cha matrix ni chikuru pachoko kuluska chisulo cha grey cast, icho nchapasi ku iron cast iron. Ntheura, chisulo cha grey cast cha thupi la mkanda chikukura chomene chikugwiriskirika nchito chomene mu mafakitale.
