Cast simbi ishoko rakajairwa resimbi-based alloys inoshandiswa kugadzira castings iyo isingaite eutectic shanduko panguva yekusimba. Rudzi rwekandwa alloy. Iwo makuru alloying zvinhu zvesimbi yakakandwa isimbi uye kabhoni sezvinhu zvikuru, uye kabhoni yemukati ndeye 0-2%. Simbi yakakandwa inokamurwazve kuita mapoka matatu: cast carbon steel, cast low low alloy simbi uye kukanda yakakosha simbi.
1. Kanda carbon steel. Kanda simbi nekabhoni sechinhu chikuru chekubatanidza uye zvidiki zvezvimwe zvinhu. Kukanda simbi yakaderera kabhoni ine kabhoni iri pasi pe0.2%, ichikanda simbi yepakati kabhoni ine kabhoni ye0.2% kusvika 0.5%, uye inokanda simbi yakakwira kabhoni ine kabhoni inodarika 0.5%. Nekuwedzera kwekabhoni yemukati, kusimba uye kuoma kwekabhoni kabhoni simbi inowedzera. Cast carbon simbi ine simba rakawanda, plastiki uye kuoma, uye mutengo wakaderera. Inoshandiswa mumichina inorema kugadzira zvikamu zvinotakura zvinorema, sezvigayo zvinotenderedza, hydraulic press bases, etc. Zvikamu zvinokanganiswa zvakare semabolster, mafuremu epadivi, mavhiri nemacouplers.
2. Kanda yakaderera alloy simbi. Kanda simbi ine alloying zvinhu zvakaita se manganese, chromium, uye mhangura. Huwandu hwese hwezvinhu zvealloying kazhinji kacho isingasviki 5%, iyo ine hukuru hwekuita kuoma uye zvirinani zvemakanika zvivakwa kuburikidza nekupisa kurapwa. Kukanda yakaderera alloy simbi ine kuita kurinani pane kabhoni simbi, iyo inogona kuderedza kunaka kwezvikamu uye kugadzirisa hupenyu hwesevhisi.
3. Kanda simbi yakakosha. Alloy cast simbi yakagadzirwa kuti isangane nezvinodiwa zvakakosha ine zvakasiyana-siyana, kazhinji iine imwechete kana kupfuura yakakwirira-alloying element kuti iwane zvimwe zvakakosha zvivakwa. Semuyenzaniso, high manganese simbi ine 11% kusvika 14% manganese inoshingirira pakupfeka uye inonyanya kushandiswa pakupfekwa kwezvikamu zvemichina yemigodhi nemichina yekuvaka; simbi dzakasiyana-siyana dzisina tsvina dzine chromium kana chromium-nickel sezvinhu zvikuru zvinosanganiswa zvinoshandiswa mukuora kana 650 Zvikamu zvinoshanda pasi pemamiriro ekushisa akanyanya pamusoro pe ℃, senge miviri yemakemikari mavharuvhu, pombi, midziyo kana chiutsi turbine casings emagetsi emagetsi makuru.
