Hale Pum Hoolei Hao Ductile

Hoʻopilikino ʻia nodular hao hoʻolei ʻana i ka pā hale ekaʻina hoʻoheheʻe one moldaʻO ka mīkini CNC.

ʻO ka hao hoʻoheheʻe ʻia, ʻo ia ka mea i hōʻike ʻia i kahi hui o ka hao, i kapa ʻia hoʻi ka hao nodular, ka hao graphite spheroidal a i ʻole ka hao SG. Loaʻa ka hao nodular i ka graphite nodular ma o ka spheroidization a me ka mālama inoculation, kahi e hoʻomaikaʻi maikaʻi ai i nā waiwai mechanical o ka hao, ʻoi aku ka paʻakikī a me ka paʻakikī, i loaʻa ai ka ikaika kiʻekiʻe ma mua o ke kila kalapona.

ʻAʻole ʻo Ductile iron he mea hoʻokahi akā he ʻāpana ia o ka pūʻulu o nā mea hiki ke hana ʻia e loaʻa i kahi ākea ākea ma o ka mālama ʻana i ka 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. ʻO ke ʻano ʻoi o nā flakes o ka graphite e hoʻokumu i nā wahi koʻikoʻi koʻikoʻi i loko o ka matrix metala a me ke ʻano poepoe o nā nodules ʻoi aku ka liʻiliʻi, pēlā e pale ai i ka hana ʻana o nā māwae a hāʻawi i ka ductility i hoʻonui ʻia e hāʻawi i ka inoa i ka alloy.

Ua ulu koke ka hao nodular i mea hao hao lua wale nō i ka hao hina a hoʻohana nui ʻia. ʻO ka mea i kapa ʻia ʻo "substituting iron for steel" e pili ana i ka hao ductile. Hoʻohana pinepine ʻia ka hao Ductile no ka hana ʻana i nā ʻāpana no nā crankshafts a me nā camshafts no nā kaʻa, tractors, a me nā ʻenekini hoʻopau i loko, a me nā puʻupuʻu medium-pressure no nā mīkini maʻamau.

Ma ke kahua hoʻolālā o nā huahana hoʻoheheʻe hao ductile, pono e hoʻonohonoho ʻia kahi hui papahana kūikawā e alakaʻi i ka "Design Failure Mode and Effects Analysis" (DFMEA). ʻO ka hui papahana he mau mea hoʻolālā huahana, nā mea hoʻolālā kaʻina hana hoʻolei, a me nā ʻoihana mālama kaiapuni. ʻO ka ʻike nui o ka loiloi DFMEA pono e hoʻokomo i nā koi o ka maikaʻi o ka hoʻoheheʻe ʻana no ka ʻāpana ʻāpana, ke kaʻina hana hoʻoheheʻe no ka hoʻoheheʻe ʻana, a me ke kaʻina hana hoʻoheheʻe no nā koi palekana kaiapuni.

ʻO nā hiʻohiʻona hana o nā mea hao hao:
• Kokoke loa ka wai a me ka emi o ka laina o ka hao ductile i ka hao hina hina.
• ʻOi aku ka nui o ka emi ʻana o ka leo a me ka hoʻokumu ʻana i ke koʻikoʻi o loko ma mua o ka hao hina hina.
• 'Oi aku ka ikaika, ka pa'a, a me ka modulus elastic o ka hao ductile ma mua o ka hao hina hina, me ke kū'ē maika'i.
• ʻOi aku ka ʻino o ka haʻalulu ma mua o ka hao hina

Nā ʻano hiʻohiʻona o nā hoʻolei hao ʻana:
• Hoʻolālā ʻia e like me ka mānoanoa o ka paia, a e hoʻāʻo e pale ʻia ka ʻāpana mānoanoa inā hiki
• No ka hoolei ana i ka pauku manoanoa a nui, pono e hoohanaia ke kukulu hakahaka a me na iwi aoao i hooikaikaia

Nā Pōmaikaʻi o ke Kaʻina Hoʻolei Sand:
• Ke kumu kūʻai haʻahaʻa ma muli o kāna mau mea hoʻoheheʻe liʻiliʻi a hiki ke hana hou ʻia a me nā mea hana maʻalahi.
• Ka laulā o ka paona ʻāpana mai 0.10 kg a 500 kgs a ʻoi aku paha.
• Nā Kūlana like ʻole mai ke ʻano maʻalahi a i ke ʻano paʻakikī.
• He kūpono no nā koi hana o nā ʻano nui.
