Simbi - yakakwira chromium kupfeka-inodzivirira bimetallic composite pombi
Chigadzirwa chacho chinoshandisa yakajairwa madziro simbi isina musono, yakakwira chrome yakakandwa simbi yakamisikidzwa inoumbwa ne centrifugal molding process kuti iumbe. Kupisa gokora rinokotamisa madziro ekunze, sarudzo yemukati meye-chromium simbi, high alloy simbi ine zvese kusapfeka, asiwo pressure, ine michanicha yepamusoro.
1. Kuita kwakanaka kwese. Wear-resistant composite pombi series kushandiswa kwembiri-metal composite casting process, yakajairika carbon steel pipe chubhu wall, yakarukwa nehigh-chromium alloy. Ose ari maviri ane yakakwira kupfeka kupikisa alloy casting, asi zvakare ane yakakwira mechanical simba uye kukanganisa kupikisa, kushandiswa kwekuchengetedza uye kuvimbika.
2. High kupfeka resistance. Yakakwira chromium yakakandwa yakaoma yeM7C3 mhando carbide, ine kusimba kwepamusoro uye kuomarara kwakanyanya (HV150-180), Rockwell kuomarara HRC50 kana kupfuura, uye nekudaro zvakanaka kupfeka kuramba.
3. Kuramba kwakasimba kwecorrosion, kupisa kwepamusoro, kupfeka kwakanyanya. Nekuti Ka carbide kuumbwa uye hunhu hwemaumbirwo pamwe nehupamhi hweCr solid solution matrix ine yakanyanya kupisa kupisa, corrosion resistance, tembiricha yakakwira kana nharaunda inoparadza inogona kuratidza kuramba kukora. Kana pakanyorova, pane corrosive media and particle erosion effect ye cross-phase conditions, kushandiswa kwewhite cast vachishandisa 28Cr simbi. Pasi pemamiriro akaoma ekushanda, sarudzo inogona kuwanikwa nekupisa kurapwa martensitic matrix yeyakakwira chromium cast simbi zvinhu.
