Maitiro ekukanda SimbiSemuenzaniso, kune maitiro ekutanga ekunyunguduka, kushandiswa kwemishonga yekupisa, uye mutengo wechigadzirwa chekupedzisira.Mukuwedzera, nzira dzekuchengetedza dzakakosha munharaunda yekushanda kwezuva nezuva mune imwe metalcasting nzvimbo.Ichi chinyorwa chinoongorora matekinoroji aya nezvimwe.Ichi chinyorwa chinosanganisirawo ruzivo rweGrey iron, Ductile iron, uye compacted graphite iron.Nzira yekukanda simbi inosanganisira matanho akawanda ekuchengetedza.Grey ironMaitiro akati wandei ekuumba anoshandiswa mugrey iron casting.Imwe neimwe ine yakasarudzika maitiro ekukanda.Kusarudzwa kwemaitiro kunoenderana zvakanyanya nekugadzirwa kwechigadzirwa chekupedzisira.Semuyenzaniso, kushandiswa kwejecha se mold media kune zvakafanana mhedzisiro pamazinga ekusimba, nepo kushandiswa kwechigarire mold process ine chiratidzo chechimiro.Nezvikonzero izvi, makambani ekukanda munzvimbo dzakasiyana anoshandisa nzira dzakasiyana dzekukanda.Ductile ironKuumbwa kwe ductile iron yekukanda simbi kunosiyana zvakanyanya.Iyo yakakosha kuumbwa isimbi, uyezve kune zvimwe zvinoumba, senge kabhoni.Mune ductile iron casting, kune kabhoni yakawanda kupfuura iyo simbi inogona kutora.Simbi, kune rumwe rutivi, inongova nekabhoni yakawanda sezvainokwanisa kutora.Mukuwedzera kune kabhoni, zvimwe zvinhu zvinowedzerwa kuti zvibudise mhinduro yakafanana.Carbon inobatsira kuumba spherical graphite zvimiro, asi inoda mamwe maalloying elements kuti igadzire.Yakasungirirwa graphite ironIko kushandiswa kwesimbi yakasungirirwa graphite yesimbi yakakandwa inopa huwandu hwezvakatipoteredza uye kushanda zvakanaka, kusanganisira kugona kushandisa zvakare zvinhu.Ichi chinyorwa chinosimbisawo nzvimbo yesimbi yakakandwa seyekutanga engineering zvinhu.Inoshandiswa zvakanyanya mukugadzirwa kwesimbi nesimbi zvikamu.Nyaya iyi inogona kugadzirwa kubva kujecha rakasvibira kana nesimbi uye inodhura.Simbi ye graphite inovimbisa inotsiviwa nesimbi inopfurwa.Alloys Graphite chinhu chakaumbwa chinesimbi uye zvisingawanzo zvinhu zvepasi.Inoumbwa nekuwedzera zvinhu zveproprietary kune iron iron isati yadira.Zvinhu izvi zvinoita kuti graphite iite machunduru ehukuru hwakasiyana.Kugovera uye saizi yemaflakes inogona kushandiswa kuti iwane izvo zvinodiwa.Muenzaniso wakanaka wegraphite ndeuyo unowanikwa musimbi isina tsvina.Mufananidzo 8 unoratidza muenzaniso we graphite flakes.Nzira yekugadziraKugadzirwa kwesimbi kunotanga nekudira simbi yakanyungudutswa muforoma.Maitiro ekukanda anogona kukamurwa kuita nhanho dzakasiyana zvichienderana nerudzi rwe molds inoshandiswa.Kune nzira dzakati wandei dzekudira dzinobva kugiravhiti kusvika kupasi-pressure.Kune mamwe akaomesesa molds, maitiro anoitwa pasi pevacuum kana kuderera kudzvinyirira.Nzira yekudira inogona kudzorwa zvakanyanya kana kushoma kuderedza chero kukanganisa kunogona kuitika musimbi.Pamusoro pezvo, ma castings akagadzirwa kubva kumarara simbi anogona kudzokororwa kuita simbi yenguruve.
