Kuponya chitoliro chachitsulo

Chitoliro chachitsulo choponyedwa chimatanthawuza chitoliro choponyedwa ndi chitsulo.Chitoliro chachitsulo cha Cast iron chimagwiritsidwa ntchito popereka madzi, ngalande ndi mapaipi otumizira gasi, kuphatikiza mapaipi owongoka achitsulo ndi zopangira zitoliro.Kuchuluka kwa ntchito ndi kochepa.Malinga ndi njira zosiyanasiyana zoponyera, zimagawidwa kukhala chitoliro chachitsulo chosalekeza ndi chitoliro chachitsulo cha centrifugal, chomwe chitoliro chachitsulo cha centrifugal chimagawidwa mu nkhungu ya mchenga ndi nkhungu zachitsulo.Malinga ndi zipangizo zosiyanasiyana, lagawidwa mu imvi kuponyedwa chitsulo chitoliro ndi ductile chitsulo chitoliro.Malinga ndi mawonekedwe osiyanasiyana, amagawidwa kukhala mawonekedwe osinthika, mawonekedwe a flange, mawonekedwe odzipangira okha, mawonekedwe okhwima, etc.

Chofunikira cha chitoliro chachitsulo ndi chitoliro chachitsulo cha ductile, chomwe chimatchedwa izi chifukwa chimakhala ndi chitsulo komanso ntchito yachitsulo.The graphite mu ductile chitsulo chitoliro alipo mu mawonekedwe ozungulira, ndipo kukula kwa graphite zambiri 6-7.Ubwino umafunikira kuti mulingo wa spheroidization wa chitoliro chachitsulo chiwongoleredwe kufika pamlingo wa 1-3, ndipo kuchuluka kwa spheroidization ndi ≥80%, kotero kuti zida zamakina azinthuzo zimasinthidwa bwino, ndi chikhalidwe chachitsulo komanso magwiridwe antchito achitsulo. .Pambuyo pa annealing, mawonekedwe a metallographic a chitoliro chachitsulo cha ductile ndi ferrite kuphatikiza pearlite pang'ono, ndipo mawonekedwe amakina ndi abwino, motero amatchedwanso chitoliro chachitsulo choponyedwa.
