Pazinthu zamakono zopangira zovundikira zitsulo zachitsulo, titha kupanga chitsulo cha ductile kudzera muzitsulo zotayidwa ndi zitsulo zopukutira, zomwe zimagwiritsidwa ntchito kwambiri pamakampani opanga makina masiku ano.Ndipotu, mfundo ya chitsulo ductile ndi kupeza graphite ndi mawonekedwe ofanana ndi mpira mwa ndondomeko spheroidization, amene bwino bwino ntchito ya chitsulo chotayidwa, makamaka plasticity ake ndi kulimba, chifukwa apamwamba apamwamba kuposa mpweya zitsulo.Komabe, pofuna kuchepetsa ndalama, zovundikira zachitsulo za ductile nthawi zambiri zimapangidwira pogwiritsa ntchito zitsulo zopangidwa ndi chitsulo.
Ductile iron ndi chinthu chophwanyika.Choyamba, chitsulo choponyedwa chimatanthawuza kukhala ndi mpweya wochuluka kuposa 2.1% (ndi carbon content ya 3.50-3.90% ndi metallographic structure ya ferrite + pearlite).Ngati mpweya wa carbon uli wochuluka, kuuma kwake kudzakhaladi kwakukulu.Kachiwiri, spheroidizing chitsulo ductile kumatanthauza kuti kukula kwa zitsulo particles amachepetsa, amenenso kusintha mphamvu ndi kuuma zinthu.Nthawi zambiri, kuuma kwa chitsulo cha ductile ndikokwera kwambiri (ndipamwamba kwambiri kuposa chitsulo wamba).
Choyamba, magalimoto olemera nthawi zambiri amagwiritsidwa ntchito mumsewu, motero zovundikira zachitsulo za ductile nthawi zambiri zimasankhidwa, zomwe zimatha kunyamula matani pafupifupi 40;Zophimba zina zapabowo zimathanso kubereka matani pafupifupi 25, zomwe ndizotsika mtengo kuposa chitsulo cha ductile.Komabe, zovundikira zitsulo zachitsulo zimakhala zotetezeka.
Kachiwiri, poyerekeza ndi zovundikira zapabowo zophatikizika, zovundikira zachitsulo zachitsulo zimakhala ndi mwayi woti akuba.Chivundikiro chachitsulo chachitsulo sichimangokhala ndi mphamvu yabwino yonyamula katundu, komanso imayang'ana kwambiri pamapangidwe a tsatanetsatane wazitsulo zonse zazitsulo zachitsulo, makamaka ponena za ntchito zotsutsana ndi kuba, kukakamiza akuba mpaka pamene alibe njira yoyambira. ndipo palibe munthu akhoza kuba.Anthu ena akhoza kuda nkhawa kuti zovundikira zazitsulo zotayira zimatha kupanga phokoso lalikulu poyendetsa, zomwe zimakhala zosafunikira chifukwa taganizira kale nkhaniyi m'mapangidwe athu.Chivundikiro cha dzenje lililonse chalandira chithandizo chochepetsera phokoso chisanachoke pafakitale, kulekanitsa kotheratu vuto la kuipitsidwa kwa phokoso la zovundikira za chitsulo cha ductile.
Pomaliza, mphamvu yonyamula katundu ya zovundikira zam'mabowo zophatikizika ndi zocheperako kuposa zovundikira zachitsulo zachitsulo.Kwa malo ngati malamba obiriwira ndi misewu yomwe safuna kupanikizika kwambiri, mtengo wogwiritsira ntchito zovundikira zapabowo zophatikizika ndi wotsika kwambiri kuposa zophimba zapabowo zachitsulo.
