Ductile Iron Sand Castings

Ductile iron inoreva simbi yakakandwa umo graphite ine denderedzwa mushure mekunge simbi yakanyunguduka yabatwa ne spheroidizing agent. Ndosaka iyo ductile cast iron ichinziwo spheroidal graphite cast iron kana nodular cast iron. Mukati meiyo ductile cast iron neelectron microsope, chimiro che spheroidal graphite chinenge chakatenderera, uye mukati mayo mune radial chimiro, uye ine pachena polarization maitiro. The spheroidization rate inoreva chikamu chehuwandu hwehuwandu hwe spherical graphite mune imwe nhanho kusvika kuhuwandu hwehuwandu hwegraphite. Iyo spheroidization rate indekisi yekuyera iyo spheroidization giredhi ye nodular cast iron, uye ndiyo yakakosha mwero mu ductile cast iron castings.
