Maitiro Parameters Of Ductile Iron Manhole Cover

Iyo mechanical properties ye grey iron yakabatana ne microstructure yematrix uye morphology ye graphite.Iyo girafu ine grey cast iron inotsemura matrix zvakanyanya, zvichikonzera kushushikana zviri nyore pamakona akapinza egraphite, zvichiita kuti kusimba kwesimbi, purasitiki, uye kuoma kwesimbi yegrey kuderera kupfuura iyo yesimbi.Nekudaro, simba rayo rekumanikidza rakafanana neresimbi, uye iri zvakare simbi yakakandwa ine yakaipisisa mechanicha zvinhu pakati pezvinowanzo shandiswa simbi yekukanda.Panguva imwecheteyo, iyo matrix chimiro zvakare ine imwe mhedzisiro pane mechaniki zvinhu zvegrey cast iron.Iyo graphite flakes yeferrite matrix grey cast iron yakaoma, ine simba rakaderera uye kuoma, saka haiwanzo kushandiswa;Iyo graphite flakes ye pearlite based grey cast iron idiki, ine simba rakawanda uye kuoma, uye inonyanya kushandiswa kugadzira zvakanyanya kukosha castings;Iyo graphite flakes yeferrite pearlite matrix grey cast iron yakakora zvishoma pane pearlite grey cast iron, uye kuita kwavo hakuna kunaka se pearlite grey cast iron.Naizvozvo, grey cast iron ine pearlite matrix inowanzoshandiswa muindasitiri.
