Lesi sihloko sidingida izakhiwo kanye nezakhi ze-alloying zensimbi nokuthi zisetshenziswa kanjani ekwenzeni izinsimbi zensimbi.Sizophinde sithinte izindleko ezihambisana nokusakazwa kwensimbi.Qhubeka ufunde ukuze ufunde kabanzi!Uhlu olungezansi yizinyathelo ezihlukene ezihilelekile ekwenziweni kokusakazwa kwensimbi.Uma usuqedile, ungaphuma uyothenga insimbi yakho yokulingisa.Okubhalwe ngezansi ezinye zezinyathelo ezibaluleke kakhulu ezihilelekile ekukhiqizeni ukukhishwa kwensimbi.Izakhi ze-alloying ngensimbiInsimbi yakhiwe izakhi ezihlukahlukene ze-alloying ezithuthukisa izakhiwo zayo zemishini.Esigabeni se-austenite, cishe asakazwa ngokufanayo.Lapho i-austenite ishisa esifundeni se-austenitic, ijwayele ukubola ibe yingxube ye-ferrite ne-carbide.I-carbide forming element ikhetha ukungena esigabeni sikasimende.Ezinye izakhi ezakha ingxubevange ziphinde zisakazwe phakathi kwezigaba ze-ferrite nezesimenti ngokusakazwa.Benza futhi ukuguqulwa kwe-austenite ku-pearlite kube nzima futhi bandise isikhathi esidingekayo ukuze sikufeze.Inqubo yokwenza ama-castings ensimbiInqubo yokwenza ama-castings ensimbi ihlanganisa ukuthela insimbi ewuketshezi esikhunjeni bese uyiyeka ibe yiqhwa.Ekupheleni kwenqubo, i-tundish cishe ayinalutho futhi i-strand iqinile.Bese, amaroli ashayelwayo ahambisa iketango lesiqalo endaweni yokupholisa yesibili.Phakathi nalesi sinyathelo, i-starter chain inqanyulwa ku-strand futhi ipholile.I-push-out roll ibe isihanjiswa phezulu esibunjeni bese iketango lokuqala lidonselwa phansi.Izakhiwo zensimbiIzakhiwo eziqinile zokubunjwa kwensimbi ziyisilinganiso sekhono lensimbi lokuthwala imithwalo ngaphansi kwezimo zokulayisha kancane.Lezi zakhiwo zikalwa ngokubeka isampula elimele ukulingisa ekulayishweni okuqinile okulawulwayo, okuwukuthi ukudonsa amandla kubha eqinile kuze kube yilapho ingxenye yehluleka.Indawo yesiphambano esincane kakhulu ngemva kokwehluleka isilinganiso samandla okudonsa okusansimbi.Ngaphezu kwalokhu, ukulingwa kwensimbi kubonisa izinga elifanayo lokuqina njengozakwabo bensimbi.Izindleko zokubunjwa kwensimbiUkufakwa kwensimbi kwenziwa kusetshenziswa izinqubo ezahlukahlukene, futhi eziningi zazo zingaphansi kokuhlolwa.Isampula elimele abalingisi lingaphansi kokulayishwa kwe-tensile okulawulwayo.Lokhu kuhlanganisa ukusebenzisa amandla okudonsa engxenyeni eyodwa ye-tensile bar ize ihluleke.Ibha egobileyo ewumphumela ihlolelwa noma yikuphi ukuqhekeka okungabazisayo.Olunye uhlobo lokuhlola ukuhlola umthelela, okubandakanya ukukala inani lamandla adingekayo ukuze kuphulwe isampula elinophawu olujwayelekile.Lapho izinga lamandla liphakeme, izinto ezisansimbi ziyaqina.Ukuhlanekezela ama-castings ensimbiIngxenye ebalulekile yekhwalithi yensimbi yokusakazwa yikhono labo lokumelana nokuhlanekezela ngesikhathi senqubo yokwelapha ukushisa.Le nqubo yaziwa ngokuthi i-annealing.Ibanga lokushisa elidingekayo ukuze kufakwe insimbi yokufaka insimbi liphakathi kuka-300掳C no-700掳C.Lolu hlu lwezinga lokushisa luyadingeka kuma-casting amakhulu anezici zokucindezeleka ezibucayi.Inqubo yokwelapha ukushisa ivamise ukwenziwa ngokuwashisisa kusengaphambili futhi ukuwapholisa kancane uma ukudonsa sekuqediwe.
