Kiʻekiʻe kaulana Kina Crawler Sprockets no Doosan Dx225lca Dx300LC Dx340lca Tractor Parts

I ka hoʻāʻo ʻana e hoʻokō maikaʻi loa i nā koi o ka mea kūʻai aku, ua hoʻokō pono ʻia kā mākou hana āpau e like me kā mākou ʻōlelo "High High Quality, Competitive Rate, Fast Service" no High Reputation China Crawler Sprockets for Doosan Dx225lca Dx300LC Dx340lca Tractor Parts, We focused ma ka hana ʻana i ka hōʻailona ponoʻī a me ka hui pū ʻana me kekahi mau huaʻōlelo akamai a me nā mea hana papa mua.Loaʻa kā mākou waiwai iā ʻoe.
I ka hoʻāʻo ʻana e hoʻokō maikaʻi loa i nā koi o ka mea kūʻai aku, ua hoʻokō pono ʻia kā mākou mau hana āpau e like me kā mākou motto "High High Quality, Competitive Rate, Fast Service" noKina Doosan Excavator Sprockets, ʻO nā ʻāpana kaʻa lalo o Doosan Excavator, Ke koi nei kā mākou hui i ke kumumanaʻo o "Quality First, Sustainable Development", a lawe ʻo "Honest Business, Mutual Benefits" i kā mākou pahuhopu hoʻomohala.Mahalo nui nā lālā a pau i ke kākoʻo o nā mea kūʻai aku kahiko a me nā mea hou.E hoʻomau mākou i ka hana ikaika a hāʻawi iā ʻoe i nā waiwai kiʻekiʻe loa a me ka lawelawe.

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 hao hooheheeia no ka wili kola, idler bracket a pela aku e like me na hapa castings i loko o 70KGS.undercarriage 'āpana track drive rim excavator sprocket
