| Grey cast iron | Kuthamanga kwabwino, kuchepa kwazing'ono panthawi yozizira, mphamvu yochepa, pulasitiki ndi kulimba, modulus zotanuka zimasiyanasiyana pakati pa 80000 ~ 140000MPa ndi ma microstructures osiyanasiyana, mphamvu yopondereza ndi 3 ~ 4 nthawi zambiri kuposa mphamvu zamakokedwe, zosavala bwinomayamwidwe ndi kugwedera.Simakhudzidwa ndi mabala ndipo imakhala ndi ntchito yabwino yodula.Kuwotcherera sikokwanira.Sichingagwiritsidwe ntchito kwa nthawi yayitali kuposa 300 ~ 400℃.85% ~ 90% mlingo wa zinthu zitsulo zotayidwa. |
| Mchitsulo chosungunuka | Kuchitapo kanthu kumakhala koyipa kwambiri kuposa chitsulo chotuwira komanso chabwino kuposa chachitsulo chonyezimira.Amagwiritsidwa ntchito popanga ma castings ang'onoang'ono okhala ndi mipanda yopyapyala yomwe ili ndi zofunika zina kuti ikhale yamphamvu komanso yolimba.Kukana bwino kwa dzimbiri komanso ntchito yabwino yopangira.Kulimba kwake ndi 3-4 kuwirikiza kawiri kuposa chitsulo chotuwa. |
| Chitsulo cha Ductile | Kuchitapo kanthu kumakhala koyipa kwambiri kuposa chitsulo chotuwira, ndipo chimakhala ndi zolakwika.Ntchito yodula ndi yabwino, ndipo chithandizo cha kutentha chingapangitse kuti ntchito yake isinthe mosiyanasiyana.Kulimba kwamphamvu ndikwambiri kuposa chitsulo chonyezimira ndi chitsulo chonyezimira, ndipo chiŵerengero cha mphamvu ya zokolola ku mphamvu yamphamvu ndi yapamwamba kuposa chitsulo chosungunuka ndi chitsulo.Pulasitiki ndi yabwino kwambiri muzitsulo zotayidwa, ndipo kulimba kwake sikuli bwino ngati chitsulo, koma chachikulu kwambiri kuposa chachitsulo chotuwa.Imakhala ndi kutentha kwapang'onopang'ono.Mphamvu ya kutopa ndipamwamba, pafupi ndi zitsulo za 45, koma kukhudzidwa kwa kupsinjika maganizo kumakhala kochepa kuposa chitsulo.Kukana kuvala bwino, kukana kutentha ndi kukana dzimbiri.Chiyerekezo cha kugwedera kwachitsulo chachitsulo, chitsulo cha ductile ndi chitsulo imvi ndi 1:1.8:4.3.zogwiritsidwa ntchito kwambiri ngati zigawo zofunika. |
| Iron Yopangidwa ndi Graphite | The makina zimatha vermicular graphite kuponyedwa chitsulo ndi pakati imvi kuponyedwa chitsulo ndi ductile chitsulo, ndipo ali compactness wabwino, kukana kutentha ndi kuvala kukana.Kapangidwe kake kabwinoko kuposa kachitsulo ka ductile komanso pafupi ndi chitsulo chotuwa.Mphamvu yake ndi yofanana ndi chitsulo cha ductile, ndipo imakhala ndi anti-vibration yofananira, kutentha kwa kutentha ndi kuponyedwa kwachitsulo chachitsulo, koma pulasitiki yabwino komanso kukana kutopa kusiyana ndi chitsulo chotuwira.Chophatikizika cha graphite kuponyedwa chitsulo mosalephera chimakhala ndi kuchuluka kwa nodular graphite.Kuwonjezeka kwa nodular graphite kudzawonjezera mphamvu zake ndi kusasunthika, koma kuwononga luso lachitsulo chosungunuka ndi kuwonongeka kwa ntchito ndi matenthedwe ma conductivity a castings. |
| kuponya zitsulo | Kuponyera kwake kumakhala kocheperako, madziwa ndi osauka, ndipo kuchepa kwake ndi kwakukulu, koma kumakhala ndi makina apamwamba kwambiri, ndiko kuti, mphamvu zambiri, kulimba ndi pulasitiki.Kulimba kwamphamvu ndi mphamvu zopondereza ndizofanana.Zitsulo zina zapadera zimakhala ndi zinthu zapadera monga kukana kutentha ndi kukana kwa dzimbiri |
| Onjezani aluminium alloy | Aluminiyamu aloyi ndi 1/3 kokha kachulukidwe chitsulo ndipo amagwiritsidwa ntchito popanga zowala zosiyanasiyana.Mafuta ena a aluminiyamu amatha kulimbikitsidwa ndi chithandizo cha kutentha kuti akhale ndi katundu wokwanira.Pamene makulidwe a khoma akuwonjezeka, mphamvu imachepa kwambiri. |
| kuponya mkuwa | Iwo agawidwa m'magulu awiri: malata mkuwa ndi Wuxi mkuwa.Mkuwa wa malata umavala bwino komanso kukana dzimbiri, kulimba kwamphamvu komanso kulimba, kusachita bwino pakuponya, ndipo sachedwa kupatukana ndi kucheperachepera.Kuzimitsa kulibe kulimbikitsa.Mkuwa wa Wuxi umagwiritsidwa ntchito kwambiri mumkuwa wa aluminiyamu kapena mkuwa wotsogola, womwe sugwira bwino ntchito.Mkuwa wa aluminiyamu uli ndi mphamvu zambiri, kukana kuvala komanso kukana dzimbiri.Mkuwa wotsogolera uli ndi mphamvu zotopa kwambiri, kutenthetsa kwamphamvu kwamafuta komanso kukana kwa asidi |
| Ikani Brass | Kuchepa kwakukulu, mphamvu zambiri, pulasitiki yabwino, kukana kwa dzimbiri komanso kukana kuvala.Kuchita bwino kwa kudula |
