Chitsulo chachitsulo, chomwe chimadziwikanso kuti chitsulo cha nodular cast kapena spheroidal graphite iron, ndi mtundu wa aloyi wachitsulo wonyezimira womwe umapangitsa kuti ductility ndi kulimba kwake zikhale zolimba chifukwa cha kukhalapo kwa tinthu tating'onoting'ono ta graphite.Zigawo zachitsulo zimagwiritsidwa ntchito m'mafakitale osiyanasiyana monga zamagalimoto, mafuta ndi gasi, zida zomangira, ndi makina aulimi.Ambiri azida za galimoto yamotondikuyimitsidwa mbalindi ductile iron.Zimaphatikiza mphamvu, kulimba, kukana kwamphamvu, kukana kwa dzimbiri komanso kutsika mtengo kwa kupanga zowonjezera.
Chimodzi mwazabwino zazikulu za chitsulo cha ductile ndi kulimba kwawo komanso kulimba kwawo.Amatha kupirira katundu wolemera ndi malo ovuta, kuwapanga kukhala abwino kuti agwiritsidwe ntchito pazinthu zomwe zimafuna kukana kwambiri kuvala, dzimbiri, ndi zotsatira.
Komanso, mbali zachitsulo zachitsulo zimapereka makina abwino ndipo ndizosavuta kuponya, zomwe zimapangitsa kuti zikhale zotsika mtengo poyerekeza ndi zipangizo zina monga chitsulo kapena aluminiyamu.Amakhalanso osinthika kwambiri, zomwe zimapangitsa kuti zitheke kupanga magawo okhala ndi mawonekedwe ovuta komanso mapangidwe.
Zigawo zachitsulo zachitsulo zakhala chisankho chodziwika bwino cha ntchito zomwe zimafuna mphamvu zambiri, kulimba, ndi zotsika mtengo, makamaka m'mafakitale omwe zipangizo zolemera ndi makina amagwiritsidwa ntchito.
Njira yachitsulo yachitsulo, yomwe imadziwikanso kuti ndondomeko yachitsulo ya nodular kapena spheroidal graphite iron process, imaphatikizapo kuwonjezera magnesiamu kapena zinthu zina zofanana ndi chitsulo chosungunuka.Izi zimapanga tinthu tating'onoting'ono ta graphite mkati mwa chitsulo, zomwe zimapatsa mphamvu zake zosiyana.
Njira yachitsulo ya ductile nthawi zambiri imayamba ndi kusungunuka kwa chitsulo mu ng'anjo, ndikutsatiridwa ndi kuwonjezera kuchuluka kwake kwa magnesium.Magnesium imakhudzidwa ndi kaboni muchitsulo, kupangitsa kupanga tinthu tating'ono ta graphite tokhala ndi mawonekedwe ozungulira.
Chitsulo chosungunukacho amathiridwa mu nkhungu ndikuloledwa kuti chizizire ndi kulimba.Chitsulo chachitsulo chikazizira ndi kulimba, chimachotsedwa mu nkhungu ndikudutsa njira zingapo zomaliza kuchotsa zinthu zonse zowonjezera.
Imodzi mwamaubwino ofunikira aductile ironndondomeko ndi kuti amalola kulenga akalumikidzidwa zovuta ndi mapangidwe.Kuonjezera apo, zitsulo zachitsulo zimatha kupangidwa pamtengo wotsika kwambiri kusiyana ndi zipangizo zina monga zitsulo, zomwe zimapangitsa kuti njirayi ikhale yodziwika bwino m'mafakitale osiyanasiyana.
