Cast steel ndi liwu lodziwika bwino la ma alloys opangidwa ndi chitsulo omwe amagwiritsidwa ntchito popanga ma castings omwe samasinthidwa eutectic panthawi yolimba. Mtundu wa alloy cast. Zinthu zazikuluzikulu zopangira zitsulo zotayidwa ndi chitsulo ndi kaboni monga zinthu zazikuluzikulu, ndipo kaboni ndi 0-2%. Chitsulo chotaya chimagawidwa m'magulu atatu: chitsulo choponyera mpweya, chitsulo chochepa cha alloy ndi chitsulo chapadera.
1. Ponyani zitsulo za carbon. Ponyani chitsulo chokhala ndi kaboni ngati chinthu chachikulu cholumikizira ndi zinthu zina zazing'ono. Kuponyera chitsulo chochepa cha carbon chokhala ndi mpweya wochepera 0.2%, kuponyera chitsulo chapakati cha carbon chokhala ndi mpweya wa 0.2% mpaka 0.5%, ndikuponyera chitsulo chochuluka cha carbon chokhala ndi mpweya woposa 0.5%. Ndi kuchuluka kwa mpweya wa carbon, mphamvu ndi kuuma kwa chitsulo cha carbon steel kumawonjezeka. Cast carbon steel ili ndi mphamvu zambiri, pulasitiki ndi kulimba, komanso mtengo wotsika. Amagwiritsidwa ntchito m'makina olemera kupanga zida zonyamula katundu wolemetsa, monga zoyimilira mphero, makina osindikizira a hydraulic, ndi zina. Zigawo zomwe zimakhudzidwanso monga ma bolster, mafelemu am'mbali, mawilo ndi ma couplers.
2. Ponyani chitsulo chochepa cha aloyi. Chitsulo choponyera chomwe chili ndi zinthu monga manganese, chromium, ndi mkuwa. Kuchuluka kwa zinthu zopangira ma alloying nthawi zambiri zimakhala zosakwana 5%, zomwe zimakhala ndi mphamvu zolimba komanso zida zabwino zamakina kudzera pakuchiritsa kutentha. Kuponyera chitsulo chochepa cha alloy kumagwira ntchito bwino kuposa chitsulo cha carbon, chomwe chingachepetse ubwino wa zigawo ndikusintha moyo wautumiki.
3. Ponyani chitsulo chapadera. Chitsulo cha aloyi chopangidwa kuti chikwaniritse zosowa zapadera chimakhala ndi mitundu yosiyanasiyana, nthawi zambiri chimakhala ndi chinthu chimodzi kapena zingapo zopangira zinthu zambiri kuti zipeze zinthu zina zapadera. Mwachitsanzo, chitsulo chokwera cha manganese chokhala ndi 11% mpaka 14% manganese sichimva kuvala ndipo chimagwiritsidwa ntchito kwambiri pazigawo zosagwira ntchito zamakina amigodi ndi makina omanga; zitsulo zosapanga dzimbiri zosapanga dzimbiri zokhala ndi chromium kapena chromium-nickel monga zinthu zazikuluzikulu zomwe zimagwiritsidwa ntchito pakuwonongeka kapena 650 Parts zomwe zimagwira ntchito pansi pa kutentha kwambiri pamwamba pa ℃, monga matupi amadzimadzi, mapampu, zotengera kapena ma turbine turbine casings amagetsi opanga mphamvu zazikulu.
