Umsebenzi we-Nodularizing Agent kanye ne-Nodularizing Elements ku-Ductile Iron Production
Umhlahlandlela wokuqukethwe: Yize kunezinhlobo eziningi zama-noduzers ekhaya naphesheya, ama-alloys e-magnesium yomhlaba asetshenziswa kakhulu njengamanje ezweni lethu.Manje sixoxa ngokuyinhloko indima yalolu hlobo lwe-alloy kanye nezakhi zalo ze-nodulizer.
Indima yezakhi ze-spheroidizing
Izinto ezibizwa nge-spheroidizing elements zibhekisela kulawo ma-elementi angakhuthaza i-spheroidization ye-graphite, akhiqize noma akhulise ama-graphite spheroids.Izakhi ezinama-spheroidized ngokuvamile zinalezi zimpawu ezilandelayo: (1) Kune-electron eyodwa noma amabili e-valence egobolondweni le-electron yangaphandle ye-elementi, nama-electron angu-8 egobolondweni lesibili elingaphakathi.Lesi sakhiwo se-elekthronikhi senza i-elementi ibe nobudlelwane obuqinile nesibabule, i-oxygen ne-carbon, ebonisa ukuzinza komkhiqizo futhi inganciphisa kakhulu isulfure nomoya-mpilo emanzini.(2) Ukunyibilika kwezakhi kunsimbi encibilikisiwe kuphansi, futhi kukhona ukuthambekela okubalulekile kokuhlukana ngesikhathi sokuqina.(3) Nakuba inokuhlobana okuthile nekhabhoni, ukunyibilika kwayo ku-graphite lattice kuncane.Ngokwezici ezingenhla, i-Mg, Ce, Y, kanye ne-Ca yizakhi ezisebenzayo ze-spheroidizing.
Ukucushwa kwezakhi ze-spheroidizing kanye nezinhlobo zama-ejenti we-spheroidizing
I-Magnesium, umhlaba ongavamile kanye ne-calcium okwamanje ibhekwa njengenamandla okukhuthaza i-graphite spheroidization, kodwa indlela yokulungiselela nokuyisebenzisa ngokuhambisana nokukhiqizwa kwemboni yangempela, hhayi kuphela ikhono le-spheroidizing le-nodulizer, kodwa futhi nokulungiselela okulula ekukhiqizeni, ukonga. izinto zokusetshenziswa, Ukusebenziseka kalula sekube yisimiso sokwenza nokusebenzisa ama-noduzers.
