Ke ʻimi nei ʻoe i kahi hopena hilinaʻi a paʻa no ka hoʻoheheʻe alumini? AʻO ka graphite Crucible no ka hoʻoheheʻe aluminikaʻo kāu pane. ʻIke ʻia no kona kūpaʻa wela maikaʻi a me ka conductivity thermal, hoʻohana nui ʻia kēia crucible i ka hoʻolei alumini a me nā mea hoʻokumu metala. Ua kūkulu ʻia e kū i nā wela wela a hāʻawi i nā hopena maikaʻi a maikaʻi loa i kēlā me kēia manawa.
ʻO kaʻO ka graphite Crucible no ka hoʻoheheʻe aluminikahana ʻia me ka hoʻohana ʻanagraphiteakalapona kalaponama o akaomi isostatic anu (CIP)kaʻina hana. ʻO kēia ʻano hana e hōʻoia i ka paʻa like ʻana o ka crucible, e pale ana i nā wahi nāwaliwali e hiki ke hana i nā māwae a i ʻole i ka wā e hoʻohana ai. ʻO ka hopena he huahana hiki ke hoʻomau i nā pōʻai he nui o ka ʻike wela kiʻekiʻe.

Q1: Hiki iaʻu ke hoʻohana i kēia crucible no nā metala ʻē aʻe ma mua o ka alumini?
ʻAe, ma waho aʻe o ka alumini, ua kūpono kēia crucible no nā metala e like me ke keleawe, zinc, a me ke kālā. He maʻalahi a hana maikaʻi no nā metala like ʻole.
Q2: Pehea ka lōʻihi o ka graphite crucible?
Aia ke ola i ka pinepine o ka hoʻohana ʻana a me ka mālama ʻana, akā me ka mālama pono ʻana, hiki i ka graphite crucible ke mau a hiki i 6-12 mau mahina.
Q3: He aha ke ala maikaʻi loa e mālama ai i kahi pahu graphite?
E hoʻomaʻemaʻe ma hope o kēlā me kēia hoʻohana ʻana, e pale i ka hoʻololi koke ʻana o ka mahana, a mālama i kahi maloʻo. Hoʻonui nui ka mālama pono ʻana i kona ola.
At Nā lako hana hana ABC, loaʻa iā mākou ma mua o 15 mau makahiki o ka ʻike i ka hana ʻanagraphite crucibleshoʻohana ʻana i ka ʻenehana ʻokiʻoki. Hoʻopuka ʻia kā mākou huahana ma ka honua holoʻokoʻa, me nā mākeke e like me Vietnam, Thailand, Malaysia, a me Indonesia. Paʻa mākou i ka hāʻawi ʻana i nā crucibles kiʻekiʻe e hāʻawi ana i ka hana maikaʻi loa a me ka lōʻihi ma nā kumukūʻai hoʻokūkū.
Ke koho ʻana i ka ponoʻO ka graphite Crucible no ka hoʻoheheʻe aluminikahiki ke hoʻonui nui i kāu hana hana a me ka maikaʻi o ka huahana. Hoʻolālā ʻia kā mākou crucibles me ka lōʻihi, ka pale wela, a me ka mālama ʻana i ka ikehu. E kelepona mai iā mākou i kēia lā no nā kikoʻī hou aku a i ʻole e kau i kahi kauoha. E hoʻomaikaʻi pū kāua i kāu hana hoʻoheheʻe metala!
