ʻO ka hao hoʻoheheʻe, ʻike ʻia hoʻi ʻo ductile cast iron, nodular cast iron, spherical graphite iron, spherical graphite cast iron a me SG iron, he ʻano o ka graphite-rich cast iron i ʻike ʻia ma 1943 e Keith Millis.ʻOiai ʻo ka hapa nui o nā ʻano o ka hao hoʻolei ʻia he nāwaliwali i ka haʻalulu a palupalu, ʻoi aku ka hopena o ka hao ductile a me ke kūpaʻa luhi, ma muli o kāna mau nodular graphite inclusions.ʻAʻole ʻo Ductile iron he mea hoʻokahi akā he ʻāpana o kahi pūʻulu o nā mea hiki ke hana ʻia me nā ʻano waiwai like ʻole ma o ka mālama ʻana i kā lākou microstructure.ʻO ka hiʻohiʻona maʻamau o kēia pūʻulu mea ʻo ke ʻano o ka graphite.I loko o nā hao ductile, aia ka graphite ma ke ʻano o nā nodules ma mua o nā flakes e like me ka hao hina.ʻOiai ʻo nā ʻōpala graphite ʻoi e hana i nā wahi koʻikoʻi i loko o ka matrix metala, nā nodules poepoe e keʻakeʻa ai i ka hana ʻana o nā māwae, no laila e hāʻawi ai i ka ductility i hoʻonui ʻia e hāʻawi i ka inoa o ka alloy.
Ua ʻike ʻia ʻo Austempered ductile iron (ADI; ʻo ia hoʻi, austenite tempered [7]) i ka makahiki 1950 akā ua kūʻai ʻia a loaʻa ka kūleʻa i kekahi mau makahiki ma hope.Ma ADI, hoʻohana ʻia ke ʻano metala ma o ke kaʻina hana wela.
Huina
ʻO ka hakina nui (%) no nā hoʻolei hao ductile ferritic[8]
He liʻiliʻi ka sulfur i loko o nā haku hao ductile ʻē aʻe.
Kalapona, 3.2–3.60%
Silika, 2.2–2.8%
Manganese, 0.1–0.2%
Magnesium, 0.03–0.04%
ʻO Phosphorus, 0.005–0.04%
Sulfur, 0.005–0.02%
Ke keleawe, <0.40%
Hao, kaulike
Hiki ke hoʻohui ʻia nā mea e like me ke keleawe a i ʻole ka tin i mea e hoʻonui ai i ka tensile a hāʻawi i ka ikaika i ka manawa like e hōʻemi ana i ka ductility.Hiki ke ho'okō 'ia ka ho'oikaika 'ana i ka corrosion ma o ka ho'ololi 'ana i ka 15-30% o ka hao i loko o ka hao me ka nui like 'ole o ka nickel, copper, a chromium.
Hiki ke hoʻololi ʻia ʻo Silicon ma ke ʻano he graphite formation element e ka alumini e hāʻawi i ka pale oxidation ʻoi aku ka maikaʻi.[9]
HONGDA Ductile hao hoolei:
I ka hoʻomaka ʻana o 2021, kūkulu ʻo HONGDA i kahi hale hana hou e hoʻolauna i nā lako hana a me ka laina hana no ka hoʻolei ʻana i ka hao Ductile.
1. Mea waiwai: QT450#-10 a me ka helu Spheroidization ma luna o ka pae III no ka loaʻa ʻana o ka maikaʻi o nā castings e kākoʻo i kāu noi.
2. Laina hana automated e hiki ai i ka hana kiʻekiʻe a me ka mana nui, 550T / Mahina, e hoʻihoʻi i kāu koi wikiwiki.
3.Applications: ductile iron castings for roller collar, idler bracket and so like parts castings within 70KGS.Being supported by a highly developed and specialist IT group, we could supply technical support on pre-sales & after-sales service for Cheap price China. ʻO Cat Bulldozer D7 D7c D7d D7e D7f Single Flange Track Roller Bottom Roller no Dozer Undercarriage, Me kahi ākea, kūlana kiʻekiʻe, nā kumukūʻai noʻonoʻo a me nā hoʻolālā nani, hoʻohana nui ʻia kā mākou hopena me kēia ʻoihana a me nā ʻoihana ʻē aʻe.
