Chitoliro chachitsulo cha ductile ndi mtundu wa chitoliro chachitsulo choponyedwa.Zofunikira zamtundu wa chitsulo choponyera chitoliro cha spheroidization grade control kwa 1-3 (spheroidization rate "80%), kotero kuti makina azinthuzo asinthidwa bwino, ndi chikhalidwe chachitsulo, chitsulo.Annealed ductile chitsulo chitoliro, kapangidwe ake metallographic ndi ferrite ndi pang'ono pearlite, zabwino makina katundu, kwambiri dzimbiri kukana, ductility wabwino, kusindikiza zotsatira zabwino, zosavuta kukhazikitsa, makamaka ntchito tapala, mafakitale ndi migodi mabizinesi madzi, mpweya, mafuta ndi zina zotero.
Kuchuluka kwa graphite yozungulira kumagawidwa pa matrix a ferrite ndi pearlite.Malinga ndi zofunikira za m'mimba mwake mwadzina ndi elongation, gawo la ferrite ndi pearlite mu masanjidwewo ndi losiyana.Kuchuluka kwa pearlite m'mimba mwake yaying'ono nthawi zambiri sikuposa 20%, ndipo m'mimba mwake yayikulu nthawi zambiri imayendetsedwa pafupifupi 25%.
Zili ndi chikhalidwe cha chitsulo, ntchito yachitsulo, ntchito yabwino kwambiri ya anticorrosion, ductility yabwino, zotsatira zabwino zosindikizira, zosavuta kuziyika, zomwe zimagwiritsidwa ntchito makamaka kwa ma municipalities, mafakitale ndi migodi madzi, gasi, mafuta ndi zina zotero.Ndilo kusankha koyamba kwa chitoliro choperekera madzi, chokhala ndi ntchito zotsika mtengo.Poyerekeza ndi chitoliro cha PE, kuyambira nthawi yoyika, kuyika kwa chitoliro cha inki chozungulira kumakhala kosavuta komanso kofulumira kuposa chitoliro cha PE, ndipo kuthamanga kwamkati ndi kunja kuli bwino pambuyo poika;Kuchokera ku airtight ndi anticorrosive mfundo, pambuyo unsembe wa ozungulira inki chubu airtight bwino, komanso kudzera zosiyanasiyana anticorrosive njira kusintha dzimbiri kukana;Pankhani ya ma hydraulic performance, machubu a inki ya spheroidal nthawi zambiri amatanthawuza m'mimba mwake, ndipo mawonekedwe a chubu cha PE nthawi zambiri amatanthawuza m'mimba mwake, chifukwa molingana ndi zomwezo, chubu cha inki cha spheroidal chimatha kukwaniritsa kuthamanga kwambiri;Kuchokera pamawonekedwe athunthu oyika ndi kukonza, chubu cha inki cha spheroidal chimakhala ndi mtengo wapamwamba kwambiri.Mkati khoma kupopera mbewu mankhwalawa nthaka, simenti matope odana ndi dzimbiri zipangizo.
