OEM Tsika Grey Iron Kukanda
Product Description
Grey iron, kana grey cast iron, imhando yemhando yesimbi yakakandwa ine graphic microstructure.Tinodaidza rudzi urwu rwegrey iron nekuda kwegrey ruvara rwekutsemuka.Kune iyo graphite inozora iyo yakachekwa nekupwanya machipisi, grey simbi ndeye yakajairika cast alloy nekuda kwemutengo wakaderera uye machinability yakanaka.Kunze kwezvo, nekuti iyo graphite inodzima yega, ine zvakare yakanaka galling uye kupfeka kuramba.
Grey iron ine zvakare kushomeka kushoma kuderera kupfuura mamwe masimbi akakanda nekuda kweiyo graphite microstructure.Iyo yekukanda, iyo silicon element inogona kukurudzira yakanaka corrosion kuramba uye kuwedzera fluidity pakukanda.Grey iron inowanzoonekwa seyakapusa kupinza.Kuenzaniswa nemamweiron castings, simbi yegrey ine simba rakaderera uye ductility;ndosaka kukanganisa uye kushomeka kuramba kwemhando iyi yezvinhu kunenge kusipo.
Inowanzo Kushandiswa Grey Iron Grades

Mune yedu yekutanga, isu tinokwanisa kugadzira grey iron castings mumhando mbiri pazasi:
Yakarasika Foam Kukanda: Iyo cheteInvestment castingmaitirwo emidziyo yesimbi yakakandwa, iyo ine zvakawanda zvakanakira kugadzira diki grey iron invesmtent castings, senge yakachengetedzwa mold mutengo, kupfupisa kutenderera kwekugadzira uye kunatsiridza kugadzirwa kwakanaka.Nekurasikirwa kwefuro kukanda maitiro, isu tinogona kubatsira vatengi vedu kuwana yakakwirira chaiyo zvigadzirwa zvine yakanakisa kupedzisa kwepamusoro, uye kushoma machining mashandiro achaitwa.
Resin Sand Kukanda: Main jecha maitiro ekukanda madiki uye epakati castings.Enzanisa nemamwe maitiro ekukanda jecha, resin jecha kukanda inzira chaiyo yekukanda padyo nekukanda kwekudyara.Sekusimba kwakanaka kwejecha resin uye kusimba kwakakwirira kwejecha mold panguva yekutanga kukanda, saka tinokwanisa kubvisa zvinobudirira shrinkage cavity, shrinkage defects yegrey iron castings.
