Yakarasika foam sand kugadzira muchina kukwikwidza grey iron castings
Grey cast iron inoreva kukanda simbi ne flake graphite, inotumidzwa zita rayo rakasviba grey fracture. Zvikamu zvikuru zvesimbi, kabhoni, silicon, manginese, Sulfu, uye phosphorous. Ndiwo anonyanya kushandiswa mhando yesimbi yakasvibiswa, accounting yeanopfuura 80% yehuwandu hwakakomberedza simbi kugadzirwa. Zvichienderana nenzira ye graphite, grey clak simbi inogona kuiswa se: zvakajairika grey cast iron, ine flake grapitite; ductile cast simbi, ine fritual graphite; kuvhenekerwa kuraswa iron, ine flaky graphite; uye honye ikakanda simbi, negwenzi rakafanana nehonye.
Nekuchenjera Sarudza zvinhu
Iko kushanda kweScource Hardness yekukanda Iron HT200-300 / QT350-50-40
Kurongeka kwechiyero
Iyo ndege yekuyera chishandiso chinoshandiswa pakurasikirwa kwekushandiswa kana mutsara kudhirowa iri yakawanda-nhanho yakasimba yekuongorora maitiro ekunyora scraping kuyerwa
Kumhanya zvakanaka
Chimiro chakasimba, kugona kwemutoro kwakakwirira, kurapwa kwemvura kuri nyore uye nekumhanya kwebasa kuri kutsanya
Kwete nyore nyore mashura
Kuyerwa kunogona kufambiswa zvakanaka pasina kukanganiswa nekunyorova uye nguva yekushandisa yakareba
Kune akawanda anowanikwa marangi ekushandisa akawanda
Inoshandiswa zvakanyanya mumachina yekugadzira, makemikari / fenicha / petroleum / metallurgy indasitiri, motokari yekugadzira uye mamwe maindasitiri
