Ntchito ya Nodularizing Agent ndi Nodularizing Elements mu Ductile Iron Production
Kalozera wazinthu: Ngakhale pali mitundu yambiri ya ma noduzer kunyumba ndi kunja, ma aloyi a magnesium osowa padziko lapansi amagwiritsidwa ntchito kwambiri mdziko lathu.Tsopano tikambirana makamaka ntchito ya mtundu uwu wa aloyi ndi zinthu zake za nodulizer.
Udindo wa zinthu za spheroidizing
Zomwe zimatchedwa spheroidizing elements zimatanthauza zinthu zomwe zingalimbikitse spheroidization ya graphite, kupanga kapena kuonjezera graphite spheroids.Zinthu za spheroidized nthawi zambiri zimakhala ndi izi: (1) Pali ma elekitironi amodzi kapena awiri pa chipolopolo cha ma elekitironi chakunja cha chinthucho, ndi ma elekitironi 8 pa chipolopolo chachiwiri chamkati.Kapangidwe kamagetsi kameneka kamapangitsa kuti chinthucho chikhale chogwirizana kwambiri ndi sulfure, mpweya ndi carbon, zomwe zimasonyeza kukhazikika kwa mankhwalawa ndipo zimatha kuchepetsa kwambiri sulfure ndi mpweya m'madzi.(2) Kusungunuka kwa zinthu muchitsulo chosungunula kumakhala kochepa, ndipo pali chizolowezi chodzipatula panthawi yolimba.(3) Ngakhale kuti ili ndi mgwirizano wina ndi carbon, kusungunuka kwake mu graphite lattice kumakhala kochepa.Malingana ndi makhalidwe omwe ali pamwambawa, Mg, Ce, Y, ndi Ca ndi zinthu zothandiza spheroidizing.
Kukonzekera kwa zinthu za spheroidizing ndi mitundu ya ma spheroidizing agents
Magnesium, osowa dziko lapansi ndi kashiamu panopa anazindikira kuti ali ndi mphamvu kulimbikitsa graphite spheroidization, koma mmene kukonzekera ndi kuwagwiritsa ntchito osakaniza enieni mafakitale kupanga, osati spheroidizing luso la nodulizer, komanso kukonzekera zosavuta kupanga, ndalama. zopangira, Kusavuta kugwiritsa ntchito kwakhala mfundo yopangira ndikugwiritsa ntchito ma nodulazer.
