Insimbi ye-Cast yigama elivamile lama-alloys asekelwe ku-iron asetshenziselwa ukukhiqiza izinto ezisakazwayo ezingenzi ukuguqulwa kwe-eutectic ngesikhathi sokuqina. Uhlobo lwe-cast alloy. Izakhi eziyinhloko ze-alloying yensimbi ekhonjiwe ziyinsimbi nekhabhoni njengezici eziyinhloko, kanti okuqukethwe kwekhabhoni kungu-0-2%. I-Cast steel iphinde ihlukaniswe izigaba ezintathu: i-cast carbon steel, insimbi ephansi ye-alloy kanye nensimbi ekhethekile.
1. Cast carbon steel. Insimbi esakazwa ngekhabhoni njengengxenye eyinhloko yengxubevange kanye namanani amancane ezinye izakhi. Isakaza insimbi yekhabhoni ephansi enokuqukethwe kwekhabhoni engaphansi kuka-0.2%, isakaza insimbi ye-carbon steel enokuqukethwe kwekhabhoni engu-0.2% kuya ku-0.5%, futhi iphonsa insimbi ephezulu yekhabhoni enokuqukethwe kwekhabhoni enkulu kuno-0.5%. Ngokukhula kokuqukethwe kwekhabhoni, amandla nobulukhuni bensimbi ye-cast carbon kuyanda. Insimbi ye-Cast carbon inamandla aphezulu, ipulasitiki nokuqina, nezindleko eziphansi. Isetshenziswa emishinini esindayo ukwenza izingxenye ezithwala imithwalo esindayo, njengezitendi zokugaya, izisekelo zokunyathelisa ezisebenza ngogesi, njll. Izingxenye ezithintekayo njengama-bolster, amafreyimu asemaceleni, amasondo nama-couplers.
2. Insimbi ye-alloy ephansi. Insimbi esakazwayo equkethe izakhi ze-alloying ezifana ne-manganese, i-chromium, nethusi. Inani eliphelele lama-elementi engxubevange ngokuvamile lingaphansi kuka-5%, elinokuqina komthelela omkhulu kanye nezakhiwo ezingcono zemishini ngokwelashwa kokushisa. Ukusakaza insimbi ye-alloy ephansi kunokusebenza okungcono kune-carbon steel, okunganciphisa ikhwalithi yezingxenye futhi kuthuthukise impilo yesevisi.
3. Sakaza insimbi ekhethekile. Insimbi eyingxubevange eyenziwe ukuhlangabezana nezidingo ezikhethekile inezinhlobonhlobo eziningi, ngokuvamile equkethe i-elementi eyodwa noma ngaphezulu ene-alloying ukuze kutholwe izakhiwo ezithile ezikhethekile. Isibonelo, insimbi ephezulu ye-manganese equkethe u-11% kuya ku-14% we-manganese imelana nokuguga futhi isetshenziselwa kakhulu izingxenye ezingagugi zemishini yezimayini nemishini yokwakha; izinsimbi ezihlukahlukene ezingenasici ezine-chromium noma i-chromium-nickel njengezici eziyinhloko ze-alloying zisetshenziswa ekugqwaleni noma ezingxenyeni ezingu-650 ezisebenza ngaphansi kwezimo zokushisa ezingaphezulu kuka-℃, njengemizimba yama-valve amakhemikhali, amaphampu, iziqukathi noma ama-casings e-turbine emusi yezitshalo zamandla amakhulu.
