| ʻO ka halihali mālama ʻole no nā noi ʻenekinia maʻamau |
| ʻO ka hana maikaʻi loa ma lalo o nā ukana māmā a me nā wikiwiki kiʻekiʻe |
| Hana ʻia e ka pauka metallurgy kaʻina a no laila kūpono no nā ʻano paʻakikī |

| Hana ʻia nā ʻano hana e kauoha ai: ʻO nā lāʻau cylindrical, nā lāʻau flanged a me nā hoʻolālā bearing maʻamau |
Hiʻona:
1. Thermal kūpaʻa: E like me ka quench acute thermal me ka hoʻohana 'ana i nā kūlana o ka graphite crucible, mākou e hoʻolālā kūikawā i ke kaʻina hana, i mea e hōʻoia ai i ka hilinaʻi o ka maikaʻi o ka huahana.
2. ʻO ke kūpaʻa ʻino: E hoʻopaneʻe ka hoʻolālā kumu a me ka maikaʻi i ka ʻino ʻana o ka crucible.
3. Ke kū'ē i ka hopena: Hiki i ka graphite crucible ke halihali i ka hopena wela kiʻekiʻe, no laila hiki ke hana i kekahi kaʻina hana.
4. Acid resistance: ʻO ka hoʻohui ʻana i nā mea kūikawā e hoʻomaikaʻi maikaʻi i ka maikaʻi o ka crucible, ʻoi aku ka nui o kāna kuhikuhi o ka pale ʻana i ka waikawa., A e hoʻolōʻihi i ke ola lawelawe o ka graphite crucible.
5. Kiʻekiʻe wela Conduction: Kiʻekiʻe maʻiʻo o ka paʻa kalapona e hōʻoiaʻiʻo i ka maikai conduction wela, pōkole ka manawa o ka hemo ana, a me remarkably hoemi i ka ikehu.
6. Ka hoʻomalu ʻana i ka haumia metala: ʻO ka ʻāpana o ka mea ma lalo o ka mana koʻikoʻi e hōʻoia i ka hiki ʻole o ka graphite crucible e hoʻohaumia i nā metala i ka wā e hemo ai.
7. Paʻa maikaʻi: ʻO ka ʻenehana kaʻina hana o ka hoʻokumu ʻana ma lalo o ke kaomi kiʻekiʻe a me ka ʻōnaehana hōʻoia maikaʻi e hōʻoia pono i ka paʻa o ka maikaʻi.
ʻO nā waiwai lubricating ponoʻī o ka carbon graphite a me nā mea graphite, me ke kūpaʻa i nā mahana kiʻekiʻe, a me ke kūʻē ʻana i ka hapa nui o nā kemika, e kūpono kēia mau mea i nā noi koi.Hiki i nā mea graphite ke hoʻonui i ka mahana a me ka laulā kemika, a me ka adjuvant kūpono, e ʻae i ka hoʻohana ʻana ma lalo o nā kūlana cryogenic.Hiki ke hoʻohana ʻia ka impregnation me nā resins a me nā metala e hoʻonui i nā waiwai o ka carbon graphite.
ʻO ka hapa nui o nā mea waiwai e wāwahi a puhi i ke ahi ma lalo o ke kiʻekiʻe kiʻekiʻe, ke kaomi kiʻekiʻe a me ke kūlana hana wikiwiki.No laila ʻaʻole hiki i ka hapa nui o nā mea hana ke hoʻohana i nā mea lubricant maʻamau e hoʻomaikaʻi i ka lōʻihi.
No laila, hoʻohana mau ʻia ke kalapona a me ka graphite bearings, pistions, piston apo a me sealing rings i nā mīkini mīkini a hiki i kēia mau ʻāpana kalapona a me ka graphite ke hana ma -200 a 200 i loko o ka corrosive medium a hiki iā lākou ke hoʻohuli maʻamau me ka wikiwiki kiʻekiʻe (e like me 100m/s) me ka aila lubricate
