Tsika Grey Kanda Iron Jecha Kukandira

Kana isu tikakanda grey iron, isu tinonyatso kutevedzera kemikari kuumbwa uye michina zvivakwa zvinoenderana nenyeredzi kana zvinodiwa kubva kune vatengi. Kunze kwezvo, isu tine kugona uye midziyo yekuyedza kana paine kukanganisa kwekukanda mukati megrey iron jecha.

Iyo ferrous alloys ine kabhoni yemukati inopfuura 2% inonzi iron iron. Kunyangwe simbi dzakakandwa dzinogona kuva nekabhoni muzana pakati pe2 kusvika 6.67, muganho unoshanda unowanzo pakati pe2 ne4%. Izvi zvakakosha zvakanyanya nekuda kwehunhu hwavo hwekukanda hwakanakisa.

Gray iron castings yakachipa kupfuuraductile iron castings, asi ine simba rakaderera uye ductility pane ductile iron. Grey iron haigone kutsiva iyo kabhoni simbi, nepo ductile iron inogona kutsiva iyo kabhoni simbi mune imwe mamiriro ezvinhu nekuda kwekusimba kwakanyanya, kusimba kwegoho uye kurebesa kweiyo ductile iron.

Kubva pane iron-carbon equilibrium diagram, zvinogona kucherechedzwa kuti simbi dzakakandwa dzine simenti uye ferrite. Nekuda kwehuwandu hwakakura hwekabhoni, huwandu hwesimende hwakakwira zvichikonzera kuoma kwakanyanya uye brittleness hunhu hwesimbi yakakandwa.

▶ Main Production Procedure
• Mapeteni & Madhizaini Ekushandisa → Kugadzira Mapeteni → Maitiro ekuumba → Kuumba Kemikari Ongororo → Kunyunguduka & Kudira → Kuchenesa, Kukuya & Kuputika Kupfura

▶ Jecha Kukandira Kuongorora Mano

• • Spectrographic uye manual quantitative analysis
• • Metallographic analysis
• • Brinell, Rockwell uye Vickers kuoma kwekuongorora
• • Kuongororwa kwemidziyo yemagetsi
• • Low uye zvakajairika tembiricha kukanganisa kuedza
• • Kuongororwa kweutsanana
• • UT, MT uye RT kuongorora

▶ Post-Casting Maitiro
