Fakitale ya Ductile Iron idakhazikitsidwa kuyambira 2021
1. Chiyambi Chachidule:
Ductile cast iron ndi chitsulo champhamvu kwambiri chomwe chinapangidwa mu 1950s.Ntchito yake yonse ili pafupi ndi yachitsulo.Kutengera ndi magwiridwe ake abwino kwambiri, idagwiritsidwa ntchito bwino popanga mphamvu zina zovuta komanso zofunika kwambiri pamphamvu, kulimba, komanso kukana kuvala.Ductile cast iron yakula mwachangu kukhala chitsulo chonyezimira chachiwiri pambuyo pa chitsulo chotuwira ndipo chimagwiritsidwa ntchito kwambiri.Zomwe zimatchedwa "chitsulo cholowa m'malo mwachitsulo" makamaka zimatanthawuza chitsulo cha ductile.Ductile cast iron imapeza ductile graphite ndi spheroidization ndi inoculation mankhwala omwe amathandizira bwino mawotchi achitsulo choponyedwa, makamaka pulasitiki ndi kulimba, potero amapeza mphamvu zapamwamba kuposa chitsulo cha carbon.
2. Kachitidwe:
Ductile iron castings yakhala ikugwiritsidwa ntchito m'magawo onse akuluakulu a mafakitale, omwe amafunikira mphamvu zambiri, pulasitiki, kulimba, kukana kuvala, kukana kutenthedwa kwa kutentha ndi makina, kukana kutentha kwapamwamba kapena kutsika, kukana kwa dzimbiri, ndi kukhazikika kwa mawonekedwe.Pofuna kuthana ndi kusintha kumeneku pamagwiritsidwe ntchito, chitsulo cha ductile chimakhala ndi magiredi ambiri, chomwe chimapereka mitundu yambiri yamakina ndi thupi.
3.Zinthu:Chithunzi cha QT450-10
4. Ntchito:
Zida zopangira zitsulo zopangira zida zamkati, monga chivundikiro chomaliza cha chonyamulira chonyamulira, kolala ya chodzigudubuza, bulaketi ya wosagwira ntchito.
5. Mphamvu yopangira:500-550T/Mwezi, Makina opanga makina.
6. Zabwino:
1) Poyerekeza ndi chitsulo chosungunula, chitsulo chopangidwa ndi ductile chili ndi mwayi wokwanira pakulimba.Kulimba kwachitsulo cha ductile cast iron ndi 60k, pomwe kulimba kwachitsulo ndi 31k yokha.Mphamvu zokolola za chitsulo chosungunuka ndi 40k, pamene chitsulo chosungunula sichisonyeza mphamvu zokolola ndipo pamapeto pake chimasweka.Chiŵerengero cha mphamvu ndi mtengo wa chitsulo cha ductile ndipamwamba kwambiri kuposa chachitsulo chosungunuka.Mphamvu ya chitsulo cha ductile imafanana ndi chitsulo chosungunuka.
2) Poyerekeza ndi zitsulo zotayidwa, Ductile cast iron ili ndi mphamvu zokolola zambiri, kuposa zitsulo zotayidwa.Mtengo wotsika wa chitsulo chozungulira cha graphite cast iron umapangitsa kuti zinthu izi zikhale zodziwika bwino, kuponya bwino kumakhala kokwera, ndipo mtengo wopangira chitsulo chozungulira wa graphite wachepa.
3) Chifukwa chake, zigawo zonyamula mphamvu za chitsulo cha ductile cast zitakonzedwa ndi feteleza annealing cycle, mawonekedwe ozungulira mkati mwa chitsulo cha ductile cast amathanso kuthetsa chodabwitsa chomwe graphite ya flake mkati mwa chitsulo chosungunula ndi yosavuta kupanga.Mu microphotograph ya chitsulo cha ductile, ming'alu imatha kutha pambuyo pofika mpira wa graphite.M'makampani opangira chitsulo, mipira ya graphite iyi imatchedwa "crack stoppers" chifukwa cha kuthekera kwawo kuletsa kusweka.
