Gray cast iron ndiye zinthu zomwe zimagwiritsidwa ntchito mu mapaipi achitsulo a SML. Ndi mtundu wachitsulo womwe umapezeka muzojambula, zomwe zimadziwika ndi maonekedwe ake otuwa chifukwa cha kusweka kwa graphite muzinthuzo. Mapangidwe apaderawa amachokera ku ma graphite flakes omwe amapangidwa panthawi yozizira, chifukwa cha mpweya wa carbon mu chitsulo.
Ikawonedwa pansi pa maikulosikopu, chitsulo chotuwira chimawonetsa mawonekedwe owoneka bwino. Tinthu tating'ono tating'ono tating'ono ta graphite timapatsa chitsulo chotuwa mtundu wake komanso chimathandizira kusinthika kwake komanso kugwetsa mpweya. Makhalidwewa amapangitsa kuti ikhale yotchuka pamasewera ovuta omwe amafunikira makina olondola komanso mapulogalamu omwe kuchepetsa kugwedezeka ndikofunikira, monga pamakina, midadada ya injini, ndi ma gearbox.
Gray cast iron imayamikiridwa chifukwa cha kusinthasintha kwake, kulimba kwamphamvu, kulimba kwa zokolola, komanso kukana mphamvu. Izi zimapangitsa kuti zikhale zoyenera kugwiritsa ntchito zosiyanasiyana m'mafakitale monga magalimoto, zomangamanga, ndi makina opanga mafakitale. Ma graphite omwe ali mu chitsulo chotuwira amakhala ngati mafuta achilengedwe, opatsa makina osavuta, pomwe kugwedezeka kwake kumachepetsa phokoso komanso kugwedezeka kwamakina. Kuphatikiza apo, kulimba kwa chitsulo chotuwira kutentha ndi kuvala kumapangitsa kukhala koyenera pazinthu monga ma brake rotor, manifolds a injini, ndi ma grate ang'anjo.
Ponseponse, kusinthasintha kwachitsulo cha grey cast iron komanso kutsika mtengo kumapangitsa kukhala chisankho chodziwika bwino pamagwiritsidwe osiyanasiyana. Ngakhale kuti imapereka mphamvu yabwino yopondereza, mphamvu yake yokhazikika imakhala yochepa kusiyana ndi chitsulo cha ductile, zomwe zimapangitsa kuti zikhale zoyenera kunyamula katundu m'malo mopanikizika. Makhalidwewa, pamodzi ndi kukwanitsa kwake, amaonetsetsa kuti chitsulo cha imvi chikupitiriza kugwira ntchito yaikulu m'mafakitale ambiri ndi kupanga.
