Hoʻolei ʻia ʻo Ductile Iron Shell Casting

He mea kaulana a hoʻokipa ʻia ka hao ductile e ke kaʻina hoʻoheheʻe ʻana i ka pūpū. Loaʻa i ka Ductile cast iron ka graphite nodular ma o nā kaʻina o ka spheroidization a me ka mālama inoculation, e hoʻomaikaʻi maikaʻi i nā waiwai mechanical, ʻoi aku ka paʻakikī a me ka paʻakikī, i loaʻa ai ka ikaika kiʻekiʻe ma mua o ke kila kalapona. ʻO ka hao hoʻoheheʻe Ductile he mea hao kiʻekiʻe me kona mau waiwai piha kokoke i ke kila. Ma muli o kāna mau waiwai maikaʻi, ua hoʻohana maikaʻi ʻia ka hao ductile no ka hoʻolei ʻana i nā ʻāpana o nā ikaika paʻakikī, ka ikaika, ka paʻakikī a me ke kūpaʻa ʻana. Hoʻohana pinepine ʻia ka hao ductile no ka hana ʻana i nā ʻāpana no nā crankshafts a me nā camshafts no nā kaʻa, nā tractor, a me nā ʻenekini hoʻopau i loko, a me nā puʻupuʻu medium-pressure no nā mīkini maʻamau.
