Malingaliro a kampani Ductile Cast Iron Investment Casting

OEM mwambo ductile kuponyedwa chitsulo castings ndindondomeko yopangira ndalamakuchokera ku China casting company. Titha kuperekanso ntchito zaCNC makina, msonkhano ndi mankhwala pamwamba.

Ma iron irons ndi ma aloyi achitsulo omwe amakhala ndi mpweya wopitilira 2%. Ngakhale zitsulo zotayidwa zimatha kukhala ndi mpweya wapakati pa 2 mpaka 6.67, malire enieni amakhala pakati pa 2 ndi 4%. Izi ndi zofunika makamaka chifukwa cha makhalidwe awo abwino oponya. Zitsulo zotayira zotuwa ndi zitsulo zachitsulo (zotchedwanso nodular cast iron kapena spheroidal graphite iron) zomwe zimagwiritsidwa ntchito kwambirikuponya maziko.

The ductile cast iron ndi nodularized iron yomwe graphite imapezeka ngati tinthu tating'ono, tozungulira, komanso timagawanitsa bwino, zotsatira zake zofooketsa ndizochepa ndipo zitsulo zoterezi zimakhala ndi ductility apamwamba. Chitsulo chamtunduwu chimatchedwa ductile kapena nodular iron kapena spheroidal graphite kapena chitsulo cha SG. Mtundu uwu wa graphite ukhoza kutheka powonjezera elemental magnesium kapena cerium kapena kuphatikiza zinthu ziwirizi ku chitsulo chosungunuka. Magnesium amawonjezeredwa ku 0.07 mpaka 0. 10% yotsatiridwa ndi kuwonjezera kwa ferro-silicon kuti apititse patsogolo graphitization. Panthawi yolimba, magnesium imathandizira kugawa ma graphite muzitsulo zonse.

Chitsulo chachitsulo chimakhala ndi chiŵerengero chabwino cha mphamvu ndi kulemera, makina abwinoko komanso kukhudzika kwakukulu. Kuphatikiza apo, ma ductile iron castings amapangidwa ndi njira yoponyera momwe kuwongolera kwapagawo kumatheka poyerekeza ndi kugwetsa kwa dontho. Chifukwa chake, zinthu zambiri monga ma crank shafts ndi ndodo zolumikizira zomwe zimapangidwa nthawi zambiri ndi dontho lolembakusinthidwa mochulukira m'malo ndi ma ductile iron castings.
