OEM Mwambo Imvi Iron Kuponya
Mafotokozedwe Akatundu
Gray iron, kapena imvi cast iron, ndi mtundu wakuthupi wachitsulo chopangidwa ndi graphic microstructure.Izi timazitcha chitsulo chotuwa chifukwa cha mtundu wotuwa wa fracture.Pakuti graphite mafuta odulidwa ndi kuswa tchipisi, imvi chitsulo ndi wamba cast aloyi chifukwa cha mtengo wotsika ndi machinability wabwino.Kupatula apo, chifukwa graphite flakes self lubricate, imakhalanso ndi galling yabwino komanso kukana kuvala.
Chitsulo chotuwa chimakhalanso ndi kulimba kocheperako kuposa zitsulo zina zotayidwa chifukwa cha graphite microstructure.Poponyera, chinthu cha silicon chimatha kulimbikitsa kukana kwa dzimbiri ndikuwonjezera madzimadzi poponya.Iron imvi nthawi zambiri imatengedwa kuti ndi yosavuta kuwotcherera.Poyerekeza ndi zinazitsulo zachitsulo, chitsulo chotuwira chimakhala ndi mphamvu yochepa komanso ductility;ndichifukwa chake kukhudzidwa ndi kukana kugwedezeka kwa zinthu zamtunduwu kumakhala kulibe.
Magulu Omwe Amagwiritsidwa Ntchito Nthawi zambiri a Gray Iron

Pachiyambi chathu, titha kupanga zitsulo zotuwa mumitundu iwiri:
Kutaya Chithovu Chotayika: Chokhachokuponya ndalamanjira zopangira zitsulo zotayidwa, zomwe zimakhala ndi zabwino zambiri zopangira zida zazing'ono zopangira chitsulo chotuwira, monga mtengo wosungidwa wa nkhungu, kufupikitsa kuzungulira kwa kupanga ndikuwongolera magwiridwe antchito.Ndi njira yotayira thovu yotayika, titha kuthandiza makasitomala athu kuti apeze zinthu zolondola kwambiri zomaliza bwino kwambiri, ndipo magwiridwe antchito ochepa azichitika.
Kuponya Mchenga wa Resin: Main mchenga kuponyera ndondomeko yaing'ono ndi sing'anga castings.Poyerekeza ndi njira zina zoponyera mchenga, kuponyera mchenga ndi njira yolondola yoponyera pafupi ndi kuponya ndalama.Monga kulimba kwa mchenga wa utomoni komanso kulimba kwa nkhungu pamchenga poyambira msanga, ndiye kuti titha kuthetsa bwino ming'alu ya shrinkage, kuwonongeka kwa chitsulo chotuwira.
