Chii chinonzi casting process
Yakatumirwa naAdmin
Kukanda (casting) inzira yekunyungudutsa simbi kuita mvura inoenderana nezvimwe zvinodiwa woidira muforoma.Mushure mekutonhora, kusimba uye kuchenesa, kukanda (chikamu kana chisina) chine chimiro chakafanotemerwa, saizi uye kuita kunowanikwa.
Nzira yekukanda kazhinji inosanganisira:
1. Kugadzirira kwe mold (mudziyo wekugadzira simbi yemvura mukati mekukanda kwakasimba).Molds inogona kupatsanurwa kuita jecha, simbi, ceramic, ivhu, graphite, nezvimwe zvinoenderana nezvinhu zvinoshandiswa, uye zvinogona kukamurwa kuita kamwe zvichienderana nehuwandu hwekushandisa.Zvinhu zvikuru zvinokanganisa kunaka kwekukanda ndeyemhando yecastings, semi-permanent uye zvachose.
2. Kunyunguduka nekudururwa kwesimbi yakakandwa.Masimbi ekukanda (casting alloys) anonyanya kusanganisira simbi yakakandwa, simbi yakakandwa uye isiri-ferrous alloys.
3. Kuongororwa kwekukanda kushandiswa, kukanda kushandiswa kunosanganisira kubvisa zvinhu zvekunze pamusoro pepakati uye kukanda pasi, kubvisa dumping risers, foshoro burrs uye overhanging joints nezvimwe zvinoputika, pamwe chete nekupisa kupisa, kuumba, kudzivirira ngura uye rough processing.
Forging inzira yekugadzira iyo inoshandisa muchina wekufogisa kuisa kumanikidza kune simbi isina chinhu kuti iburitse deformation yepurasitiki kuti uwane mafogi ane mamwe ma mechanic properties, mamwe maumbirwo uye saizi.
Kuburikidza nekugadzira, iyo as-cast looseness yesimbi uye maburi ewelding anogona kubviswa, uye ma mechanic zvimiro zveakafodhiwa zvikamu zvinowanzove zviri nani pane izvo zvekukanda zvechinhu chimwe chete.Kune akakosha mamechani zvikamu zvine mutoro wakakwira uye nehutsinye mamiriro ekushanda, kuwedzera kune akareruka maumbirwo, maprofiles kana welded zvikamu zvinogona kukungurutswa, forgings inonyanya kushandiswa.
