Noduzers ndi zitsulo kapena ma aloyi omwe amawonjezeredwa kuchitsulo chosungunuka kuti apeze chitsulo chozungulira cha graphite.Ma noduzers omwe amagwiritsidwa ntchito kwambiri m'dziko langa ndi ferrosilicon rare earth magnesium alloys, ndipo mayiko ambiri akunja amagwiritsa ntchito ma noduzers a magnesium (oyera magnesium ndi magnesium alloys)., mayiko oŵerengeka amagwiritsira ntchito ma calcium nodulazer.
Spheroidal graphite mu ductile cast iron imapangidwa ndi spheroidizing chitsulo chosungunula chosungunuka, chomwe chimachipangitsa kukhala champhamvu kwambiri kuposa chitsulo chonyezimira komanso cholimba kuposa chitsulo chosungunula chonyezimira, ndikusunga zabwino zingapo zachitsulo chonyezimira.Komabe, "spheroidizer" yomwe imagwiritsidwa ntchito popanga chitsulo cha ductile imatha kukulitsa chizolowezi chowotcherera kuti chipange "mkamwa woyera" ndi mawonekedwe olimba, ndikupangitsa ming'alu m'dera lomwe limakhudzidwa ndi kutentha (makamaka fusion zone).Choncho, weldability wa chitsulo ductile ndi zoipa kuposa imvi kuponyedwa chitsulo.
Zosakaniza za nodulizer: magnesium, nthaka yosowa, silicon, calcium, barium, chitsulo, etc.;
Nodulizer chitsanzo: 3-8 nodulizer, 5-8 nodulizer, 7-8 nodulizer;
Kukula kwa tinthu tating'onoting'ono: 5-30mm (itha kukonzedwanso malinga ndi zomwe makasitomala amafuna), makulidwe amtundu wakuda osapitilira 100mm!
