Lokacin kwatanta simintin simintin gyare-gyare da ductile iron, yana da mahimmanci a fahimci cewa yayin da duka biyun nau'in baƙin ƙarfe ne, suna da kaddarorin da suka dace kuma sun dace da aikace-aikace daban-daban. Ga cikakken kwatance:
1. Abun Haɗin Kai da Tsarin
Ƙarfin simintin gyare-gyare:
Abun da ke ciki:Ƙarfin simintin gyare-gyarean ƙirƙira shi ta hanyar farin ƙarfe na simintin gyaran zafi, wanda ya ƙunshi carbon a cikin nau'in carbide baƙin ƙarfe (Fe3C). Maganin zafi, wanda aka sani da annealing, yana rushe ƙarfe na carbonide, yana barin carbon ya samar da graphite a cikin nodular ko rosette form.
Tsarin: Tsarin annealing yana canza tsarin ƙananan ƙarfe na ƙarfe, yana haifar da ƙananan ƙananan ƙwayoyin graphite marasa tsari. Wannan tsarin yana ba da kayan tare da wasu ductility da tauri, yana mai da shi ƙasa da gatse fiye da simintin ƙarfe na gargajiya.
Ƙarfin Ƙarfi:
Abun Haɗawa: Ƙarfin ƙarfe, wanda kuma aka sani da nodular ko spheroidal graphite iron, ana samar da shi ta hanyar ƙara abubuwa masu ƙima kamar magnesium ko cerium zuwa narkakken ƙarfe kafin yin simintin. Wadannan abubuwa suna sa carbon ya zama kamar spheroidal (zagaye) nodules graphite.
Tsarin: Tsarin graphite mai siffar zobe a cikin baƙin ƙarfe na ductile yana haɓaka ductility da juriya mai tasiri, yana ba shi kaddarorin injiniya mafi girma idan aka kwatanta da baƙin ƙarfe maras nauyi.
2. Kayayyakin Injini
Ƙarfin simintin gyare-gyare:
Ƙarfin Ƙarfin Ƙarfin Ƙarfi: Ƙarfin simintin gyare-gyare yana da matsakaicin matsakaicin ƙarfi, yawanci daga 350 zuwa 450 MPa (megapascals).
Ductility: Yana da ma'ana mai ma'ana, wanda ke ba shi damar lanƙwasa ko lalacewa a ƙarƙashin damuwa ba tare da fashe ba. Wannan ya sa ya dace da aikace-aikace inda ake buƙatar wasu sassauci.
Juriya Tasiri: Yayin da yake da ƙarfi fiye da simintin ƙarfe na gargajiya, simintin simintin gyare-gyare ba shi da juriya idan aka kwatanta da baƙin ƙarfe.
Ƙarfin Ƙarfi:
Strowerarfin tensile: baƙin ƙarfe na duhun da ke da ƙarfi mai yawa, galibi yana faruwa daga 400 zuwa 800 MPa, ya danganta da daraja da magani mai zafi.
Ductility: Yana da matuƙar ductile, tare da adadin haɓakawa yawanci tsakanin 10% da 20%, ma'ana yana iya shimfiɗa sosai kafin fashe.
Tasirin Tasiri: An san ƙarfen ƙarfe don kyakkyawan juriya mai tasiri, yana mai da shi manufa don aikace-aikacen da ke ƙarƙashin ɗaukar nauyi ko babban damuwa.
3. Aikace-aikace
Ƙarfin simintin gyare-gyare:
Amfani na gama gari: Ana amfani da ƙarfe mai yuwuwa sau da yawa a cikin ƙarami, ƙarin ƙaƙƙarfan simintin gyare-gyare kamar kayan aikin bututu, braket, da kayan masarufi inda ake buƙatar matsakaicin ƙarfi da wasu sassauƙa.
Muhalli na yau da kullun: Ana amfani da shi a cikin aikin famfo, bututun iskar gas, da aikace-aikacen masana'antu masu haske. Ƙarfin kayan don ɗaukar girgiza da girgiza ya sa ya dace da shigarwa da ya shafi motsin inji ko faɗaɗa zafi.
Ƙarfin Ƙarfi:
Amfani na yau da kullun: Saboda ƙarfin ƙarfinsa da taurinsa, ana amfani da baƙin ƙarfe a cikin manyan aikace-aikace masu buƙata kamar kayan aikin mota (misali, crankshafts, gears), tsarin bututu mai nauyi, da sassa na gini a cikin gini.
Muhalli na yau da kullun: Ƙarfin ƙarfe yana da kyau don amfani a cikin bututun matsa lamba, ruwa da tsarin najasa, da kuma yanayin da abubuwan da aka haɗa su ke fuskantar matsanancin damuwa na inji ko lalacewa.
Kammalawa
Ƙarfe mai yuwuwa da baƙin ƙarfe ba iri ɗaya ba ne. Waɗannan nau'ikan baƙin ƙarfe ne daban-daban waɗanda ke da kaddarori da aikace-aikace daban-daban.
Iron malleable ya dace da ƙarancin aikace-aikacen da ake buƙata inda ingancin farashi da matsakaicin kaddarorin inji suka wadatar.
Sabanin haka, an zaɓi baƙin ƙarfe na ductile don ƙarin ƙalubalen muhalli inda ake buƙatar ƙarfin ƙarfi, ductility, da juriya mai tasiri.
