EN877 Cast Iron Zopangira
Gray cast iron imatanthawuza chitsulo chonyezimira chokhala ndi flake graphite, chomwe chimatchedwa chitsulo chotuwa chifukwa chothyokacho chimakhala chotuwa chakuda chikasweka. Zigawo zazikuluzikulu ndi chitsulo, carbon, silicon, manganese, sulfure, ndi phosphorous. Ndiwo chitsulo chogwiritsidwa ntchito kwambiri ndipo zotsatira zake zimaposa 80% ya chitsulo chonsecho. Chitsulo cha Grey chili ndi zida zabwino zoponyera ndi kudula komanso kukana kuvala bwino. Ntchito kupanga poyimitsa, makabati, etc. The graphite mu imvi kuponyedwa chitsulo mu mawonekedwe a flakes, ogwira kubala m'dera ndi yaing'ono, ndi nsonga graphite sachedwa kupsinjika maganizo ndende, kotero mphamvu, plasticity, ndi kulimba kwa imvi. zitsulo zotayidwa ndi zochepa kuposa zitsulo zina. Koma ili ndi kugwedera kwabwino kwambiri, kukhudzika kwa notch, komanso kukana kwambiri kuvala.
Gray cast iron imakhala ndi mpweya wambiri (2.7% mpaka 4.0%), womwe ukhoza kuwonedwa ngati matrix a carbon steel kuphatikiza flake graphite. Malinga ndi mapangidwe osiyanasiyana a masanjidwewo, chitsulo cha imvi chimagawidwa m'magulu atatu: chitsulo cha ferrite matrix imvi; pearlite-ferrite masanjidwewo imvi kuponyedwa chitsulo; pearlite masanjidwewo imvi kuponyedwa chitsulo
Pakali pano, mankhwala athu imvi kuponyedwa chitsulo makamaka kuponyedwa chitsulo ngalande zovekera chitoliro.
