ʻO ka hoʻohana maʻamau o ka graphite crucible silicon carbide

I ka honua o ka metallurgy, ka hana foundry, a me nā noi wela kiʻekiʻe, pono ka maikaʻi a me ka lōʻihi o nā crucibles no ka hōʻoia ʻana i ka maikaʻi a me ka maikaʻi o ka huahana. ʻO nā mea hoʻoheheʻe Silicon Graphite, i haku ʻia me ka graphite a me ka silicon carbide, ua lilo i mea koho maikaʻi loa no nā ʻoihana e makemake ana i nā mea hiki ke kū i ka wela nui a me nā kaiapuni kemika paʻakikī. ʻO ka hoʻohana hou ʻana okaomi isostatici ka hana ʻana i kēia mau crucibles e hoʻonui i ka lōʻihi a me nā waiwai wela, e hoʻolilo iā lākou i mea kūpono no ka koi ʻana i nā noi ʻoihana.


ʻO nā hiʻohiʻona koʻikoʻi o ka Silicon Graphite Crucibles

Hiʻona Pōmaikaʻi
Paʻi Isostatic Hāʻawi i ka paʻa like like, e hōʻoia ana i ka ikaika a me ka lōʻihi.
Hoʻohui ʻia ʻo Graphite-Silicon Carbide Hāʻawi maikaʻi i ka conductivity thermal a me ka pale ʻana i ka corrosion.
ʻO ka hoʻomanawanui kiʻekiʻe Kū i ka wela nui me ka ʻole o ka hoʻokō ʻana.

Ka hoohana ana okaomi isostaticHe mea ʻokoʻa nui ia i ka hana ʻana i nā crucibles graphite silika. ʻO kēia ʻano hana e pili ana i ka hoʻopili ʻana i ke kaomi like ʻole i ka mea, ka hopena i kahi huahana me ka paʻa a me ke ʻano. ʻO ka hopena he crucible hilinaʻi, hiki ke mālama i kona ʻano a me kāna hana ma lalo o nā kūlana koʻikoʻi.

ʻO nā pono o ka hoʻohana ʻana i nā Crucibles Isostatically Pressed

Nā pōmaikaʻi o ka hoʻohana ʻananā kīʻaha graphite kilikaka i hoʻopaʻa ʻiaʻoi aku ma mua o ka lōʻihi wale nō:

  • ʻOi aku ka maikaʻi o ka wela wela: Hoʻomaʻamaʻa kēia mau crucibles i ka hāʻawi ʻana i ka wela, he mea koʻikoʻi no ka hoʻoheheʻe ʻana a me ka hoʻolei ʻana.
  • Kū'ē i ka ʻino a me ka ʻokiʻoki: Hāʻawi ka ʻāpana silicon carbide i kahi pale paʻa e kūʻē i nā hopena kemika a me ka oxidation, e hoʻolōʻihi i ke ola o ka crucible.
  • Hoʻonui i ke ola: Ma muli o ke ʻano kiʻekiʻe o ka haku mele a me ke kaʻina hana like ʻole, ʻoi aku ka lōʻihi o kēia mau crucibles ma mua o nā mea i hana ʻia me nā ʻano kuʻuna.

Mālama a me nā hana maikaʻi loa

He mea koʻikoʻi ka mālama pono i ka hoʻonui ʻana i ke ola onā kīʻaha graphite silika. Eia kekahi mau ʻōlelo aʻoaʻo mālama:

  1. Hoʻomalu wela: Hōʻalo i ka hoʻololi wikiwiki ʻana i ka wela no ka pale ʻana i ka haʻalulu wela, hiki ke alakaʻi i ka pohā.
  2. Hoomaemae mau: Pono e hoʻoneʻe ʻia nā mea koena a i ʻole nā ​​papa oxidation no ka mālama ʻana i ka hana o ka crucible.
  3. Pale ana i ka Poino Kemika: Ke hoʻohana ʻia i loko o nā wahi kemika koʻikoʻi, e nānā pono i ka crucible no nā hōʻailona mua o ka corrosion.

Ma ka hahai ʻana i kēia mau hana maikaʻi loa, hiki i nā crucibles ke lōʻihi aku, e hāʻawi ana i ka waiwai i kāu mau hana.


Pehea ʻo Isostatic Pressing e hoʻomaikaʻi ai i ka maikaʻi o ka huahana

ʻO kakaomi isostaticʻenehana i hoʻohana ʻia i ka hana ʻana i nā crucibles graphite silika hiki ke:

Nā Pōmaikaʻi Paʻi Isostatic Nā Hana Kuʻuna
ʻAʻahu like ʻole Hiki ʻole ke ʻano like ʻole i ka nui
Hoʻomaikaʻi ʻia ka paʻa o ka hale ʻOi aku ka nui o nā hemahema
Hoʻonui i nā waiwai wela Haʻahaʻa wela conductivity

ʻO ka paʻi like ʻole i hoʻohana ʻia i ka wā e kaomi ʻana isostatic e hoʻopau i nā mea like ʻole, e hopena i kahi crucible i ʻoi aku ka paʻa, ikaika, a ʻoi aku ka hilinaʻi. Hoʻohālikelike ʻia me nā ʻenehana kaomi kuʻuna, hana ʻo isostatic pressing i kahi huahana e hāʻawi ana i ka hana ʻoi aku ka maikaʻi ma nā kaiapuni kiʻekiʻe a me nā kemika.


Kāhea i ka hana

I ka hiki ʻana mai i ka hoʻonui ʻana i ka pono a me ka lōʻihi o kāu kaʻina hana ʻoihana, ke koho ʻana i ka crucible kūpono ka mea nui.ʻO nā kīʻaha graphite silikahana ʻia me ka hoʻohana ʻana i kakaomi isostaticHāʻawi ka ʻenehana i ka ʻoi aku ka lōʻihi, ke kūpaʻa i ka haʻalulu wela, a me ka lōʻihi i nā kūlana paʻakikī. Inā ʻoe e hana ana ma ka ʻoihana foundry, metallurgical, a i ʻole nā ​​​​mea kemika, hiki i kēia mau crucibles ke hoʻomaikaʻi nui i kāu kaila hana a me ka maikaʻi o ka huahana.
