Ukukhishwa kwensimbi kubhekisela ekubunjweni okukhiqizwe yinsimbi ye-alloy kuhlanganise namakhulu ezinhlobo zamamaki ensimbi, akhiqizwa izinqubo eziningi zokuphonsa ezifana nokusakazwa kwesihlabathi, ukubunjwa kwamagobolondo,ukutshala imali, ukukhishwa kwegwebu okulahlekile nokukhipha i-vacuum cast. Ukukhishwa kwensimbi kungasetshenziswa ezimweni ezihlukahlukene zokusebenza ezihlukene, futhi izici zayo ezibanzi zemishini zingcono kunanoma yikuphi okunye ukukhishwa kwe-alloy. Futhi kunezinhlobonhlobo zezinsimbi eziphezulu ze-alloy ezifanele izinjongo ezikhethekile.Izinsimbi zensimbizisetshenziswa ngokukhethekile kulezi zimo: izingxenye ezingaphansi kokucindezeleka okukhulu noma umthwalo oguquguqukayo, ukusakazwa kwemikhumbi yokucindezela okubalulekile, izingxenye ezingaphansi kwemithwalo emikhulu emazingeni okushisa aphansi noma aphezulu kanye nezinye izingxenye ezibalulekile. Izingxenye ezisebenza ngaphansi komthelela nezimo zokugqoka kufanele ziphonswe ngensimbi ephezulu ye-manganese.
Izinsimbi zensimbi zihlukaniswa ngokwamakhemikhali azo futhi zihlukaniswe izingxenye ze-cast carbon steel, izingxenye zensimbi ye-alloy kanyeinsimbi engagqwali izingxenye. Ngokuya ngezigaba zezici zokusetshenziswa, izinsimbi zensimbi zingahlukaniswa zibe insimbi yobunjiniyela nesakhiwo (insimbi ye-carbon alloy ne-alloy structural steel), inkatho yensimbi ekhethekile (insimbi engagqwali engagqwali, insimbi engashi, insimbi engagugi, ingxubevange esekwe nickel ) kanye nensimbi yensimbi yokuphonsa (insimbi yethuluzi, insimbi yokufa). Embonini ye-Foundry, izinto ezisetshenziselwa ukukhishwa kwensimbi ngokuvamile zihlukaniswa ngale ndlela elandelayo:
1) Faka i-carbon steel: insimbi ye-carbon ephansi, insimbi ye-carbon medium, insimbi ephezulu ye-carbon steel (insimbi ye-carbon steel ephezulu)
2) Insimbi ye-Medium-alloy kanye nensimbi ye-alloy ephansi yokusakaza: cast manganese steel, cast silico-manganese steel, cast manganese-molybdenum steel, cast manganese-molybdenum-vanadium copper steel, cast chromium steel, chromium-molybdenum cast steel, chromium-manganese-silicon cast steel, chromium-manganese cast iron Molybdenum , i-chromium molybdenum vanadium cast steel, i-chromium copper cast steel, i-molybdenum cast steel, i-chromium nickel molybdenum cast steel, njll. Izakhi zamakhemikhali ezihlukene zingadlala indima ehlukile ekuthuthukiseni ukusebenza okuhambisanayo. Ezihlokweni ezilandelayo, sizokwethula izakhiwo zezinsimbi ze-alloy ezihlobene kanye nezindima ezidlalwa izakhi zamakhemikhali ngayinye ngayinye.
3) Insimbi engagqwali engagqwali: insimbi engagqwali ye-ferritic, insimbi engagqwali ye-martensitic, insimbi engagqwali ye-austenitic kanyeinsimbi engagqwali ye-austenitic-ferritic duplex.
4) Insimbi ekwazi ukumelana nokushisa: insimbi ephezulu ye-chromium, insimbi ye-nickel ephezulu ye-chromium nensimbi ephezulu ye-nickel chromium.
5) Insimbi engagudluki engagqoki: insimbi ye-manganese engagugi, insimbi engagugi ye-chromium
6) Ukusakaza insimbi ekhethekile kanye nensimbi yobungcweti: insimbi ekhonjiwe enezinga lokushisa eliphansi, insimbi yensimbi etholakalayo (insimbi yokufa), insimbi yokucindezela, insimbi yokufaka enembile, ipayipi lensimbi eliyi-centrifugal cast.
Kodwa-ke, ukumuncwa ukushaqeka, ukumelana nokugqoka, uketshezi kanye nezakhiwo zokuphonsa zensimbi zimbi kakhulu kunezoinsimbi empungakanye ne-ductile cast iron. Ngesikhathi esifanayo, izindleko ze-castings zensimbi ziphakeme kunezinsimbi zensimbi. Ukwengeza, ngaphansi kwezimo ezifanayo zokuqina, isisindo esihlobene sokusakazwa kwensimbi siphindwe kabili kune-aluminium alloy castings. Ngakho-ke, lapho ukhetha insimbi ekhonjiwe, kuyadingeka ukuthi ucabangele ngokuphelele ukusetshenziswa kwangempela nokusebenza kwezindleko, futhi wenze ukukhetha okunengqondo kakhulu.
