Kaulana maikaʻi o ka mea hoʻohana no Kina Sumitomo Undercarriage Track Roller Construction Machinery Parts Spare Parts
ʻO ka mea maʻamau ka mea kūʻai aku, a ʻo kā mākou manaʻo nui i ka lilo ʻana ʻaʻole wale i ka mea hilinaʻi, hilinaʻi a me ka ʻoiaʻiʻo hoʻolako, akā ʻo ka hoa no kā mākou mea kūʻai aku no ka maikaʻi o ka mea hoʻohana no Kina Sumitomo Undercarriage Track Roller Construction Machinery Spare Parts, ma o ka 8 mau makahiki o ka ʻoihana liʻiliʻi, ua hōʻiliʻili mākou i ka ʻike waiwai a me nā ʻenehana holomua i ka wā o ka hana ʻana i kā mākou huahana.
ʻO ka mea maʻamau e pili ana i nā mea kūʻai aku, a ʻo kā mākou manaʻo hope loa i ka lilo ʻana ʻaʻole wale i ka mea hoʻolako hilinaʻi, hilinaʻi a me ka ʻoiaʻiʻo, akā ʻo ka hoa pū kekahi no kā mākou mea kūʻai aku noNā ʻāpana ʻāpana ʻo Kina Sumitomo, Nā ʻāpana kaʻa lalo o Sumitomo, Ke hilinaʻi nei i ka maikaʻi a me ka maikaʻi ma hope o ke kūʻai aku, kūʻai maikaʻi kā mākou huahana ma ʻAmelika, ʻEulopa, Middle East a me South Africa.ʻO mākou hoʻi ka hale hana OEM i koho ʻia no nā huahana huahana kaulana.Welina mai e hoʻokaʻaʻike mai iā mākou no ke kūkākūkā hou a me ka launa pū ʻana.

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.

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%

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 hao hoolei no ka wili kola, idler bracket a pela aku e like me ka hapa castings i loko o 70KGS.Generally mea kūʻai mai-oriented, a me ka mea i ko makou manao hope ma luna o ka lilo ole wale pono i ka loa hilinaʻi, hilinaʻi a me ka pono mea hoʻolako, akā, i ka hoa. no kā mākou mau mea kūʻai no ka inoa maikaʻi o ka mea hoʻohana no Kina Sumitomo Undercarriage Track Roller Construction Machinery Spare Parts, Ma o 8 mau makahiki o ka ʻoihana liʻiliʻi, ua hōʻiliʻili mākou i ka ʻike waiwai a me nā ʻenehana holomua i ka wā o ka hana ʻana i kā mākou huahana.
Kaulana maikaʻi o ka mea hoʻohana noNā ʻāpana ʻāpana ʻo Kina Sumitomo, Nā ʻāpana kaʻa lalo o Sumitomo, Ke hilinaʻi nei i ka maikaʻi a me ka maikaʻi ma hope o ke kūʻai aku, kūʻai maikaʻi kā mākou huahana ma ʻAmelika, ʻEulopa, Middle East a me South Africa.ʻO mākou hoʻi ka hale hana OEM i koho ʻia no nā huahana huahana kaulana.Welina mai e hoʻokaʻaʻike mai iā mākou no ke kūkākūkā hou a me ka launa pū ʻana.
