Incazelo yokwenza insimbi: susa ukungcola kunsimbi yengulube kanye nezilahliwe nge-oxidation bese wengeza inani elifanele lezakhi ze-alloy ukuze wenze insimbi enamandla aphezulu, ukuqina noma ezinye izici ezikhethekile.Le nqubo ibizwa ngokuthi "i-steelmaking".
Kuma-alloys e-iron carbon anokuqukethwe kwekhabhoni ≤ 2.0%, ukubaluleka kuka-2.0% C kumdwebo wesigaba se-iron carbon.Ukushisa okuphezulu: i-austenite, ukusebenza okuhle kokusebenza okushisayo;Izinga lokushisa elijwayelekile: ikakhulukazi i-pearlite.
Kungani kwenziwa insimbi: insimbi yengulube ayikwazi ukusetshenziswa kabanzi.Okuqukethwe kwekhabhoni ephezulu: akukho austenite ekushiseni okuphezulu;Ukusebenza okungalungile: okuqinile futhi okuqinile, ukuqina okubuthakathaka, ukusebenza kabi kwe-welding, ayikwazi ukucubungula;Ukungcola okuningi: okuqukethwe okuphezulu kwe-S, P kanye nokufakiwe.
Izakhi ezivamile ensimbi: izakhi ezinhlanu: C, Mn, s, P kanye no-Si (kuyadingeka).Ezinye izakhi: V, Cr, Ni, Ti, Cu, njll. (ngokwezinga lensimbi).Izizathu ezikhona: ① umkhawulo wenqubo: s kanye no-P azikwazi ukususwa ngokuphelele;② Izinsalela zezinto ezingavuthiwe: Izinsalela ezilahliwe Cu, Zn;③ Izakhiwo ezithuthukisiwe: UMn uthuthukisa amandla futhi u-Al ucwenga okusanhlamvu.Okuqukethwe kwe-elementi: ① Izimfuneko ezijwayelekile zikazwelonke: GB;② Izinga lebhizinisi: linqunywa ibhizinisi;③ Amanye amazinga kazwelonke: swrch82b (Japan).
Umsebenzi oyinhloko wokwenza insimbi: umsebenzi oyinhloko wokwenza insimbi ukucwenga insimbi encibilikisiwe kanye nezinsimbi ezilahliwe zibe insimbi enokwakheka kwamakhemikhali adingekayo, futhi kuyenze ibe nezinto ezithile ze-physicochemical kanye nemishini.Umsebenzi oyinhloko ufinyezwa ngokuthi "ukususwa okune, ukususwa okubili kanye nokulungiswa okubili".
4. I-Decarbonization, i-desulfurization, i-dephosphorization kanye ne-deoxidation;
Ukususwa okubili: ukususa amagesi ayingozi nokungcola;
Ukulungiswa okubili: lungisa izinga lokushisa lensimbi ye-liquid kanye nokwakheka kwe-alloy.
