Ka hopena omea hoʻopololei（nodularizer） ma ka hao hoolei he elua mau mea:
1， ʻO ka honua maʻamau e like me ka mea nodulating i hoʻoheheʻe ʻia i ka hao i hoʻoheheʻe ʻia he hopena ikaika i ka hoʻokumu ʻana o ka carbide. He mea antigraphitized ia. iron.Reduce;Inā nui ka hoʻohui, e hoʻomaikaʻi ʻia ka manaʻo o ka hao.
2, I ka manawa o kamea hoʻopololeiLoaʻa i nā mea o ka honua kakaʻikahi, paʻa loa kona sulfide a me nā oxides, liʻiliʻi ka nui o ka nui, paʻakikī ke lana i ka hao i hoʻoheheʻe ʻia. graphite nuclei.Magnesium oxide MgO he mea spheroidizing me ke kiʻekiʻe heheʻe wahi, maikai paʻa a me ka haʻahaʻa solubility i loko o ka hao hooheheeia, akā, i ka nui o ka particle nui, e lana i ka ili e lilo i scum, a i ole e komo i loko o ka. hoʻolei ʻana i ka hoʻokomo ʻana i ka slag.
Nodulizer(ReMgSiFe), he mea hoʻohui i hiki ke hoʻoikaika i ka hana ʻana o ka graphite spheroidal mai nā ʻāpana graphite i nā kaʻina hana.Hiki iā ia ke hoʻoulu i nā graphites spheroidal a hoʻonui i ka helu o nā graphites spheroidal i mea e hoʻomaikaʻi ai ko lākou mau pono mechanical.ʻO ka hopena, ua hoʻomaikaʻi ʻia ka ductility a me ka paʻakikī o nā huahana i hoʻoikaika nui ʻia ko lākou mana a me nā hana.
ʻO ka honua nui ʻolenodulizerse hauʻoli i nā mana ikaika me ka anti-recession, anti-distortion a me ka anti-interference i ke kaʻina hana.Hoʻomalu ʻia kona magnesia i loko o 0.6%.Me ka hao hooheheʻe kumu paʻa a me ka ʻenehana nodulizing makua, hiki ke hoʻomalu paʻa ʻia ke koena magnesium.
