Hexi kalapona hana nui graphite electrodes. Ma waho aʻe o nā electrodes graphite, hana mākou i kekahi mau huahana graphite. ʻO ke kaʻina hana o kēia mau huahana graphite ke kaʻina like a me ka nānā maikaʻi e like me nā electrodes graphite. ʻO kā mākou huahana graphite ka nui o ka graphite crucible, graphite cube, graphite rod a me carbon rod, etc. Hiki i nā mea kūʻai ke hana i nā huahana graphite me nā ʻano like ʻole e like me ko lākou pono. ʻO ke kaʻina hana o nā huahana graphite e hoʻohui i ka petroleum coke me ka asphalt. A laila, kiʻi ʻia nā ʻātoma kalapona ma ke kaomi ʻana, ka kuke ʻana a me ka ʻai ʻana i kahi mahana kiʻekiʻe o 3000 ℃. A laila hana ʻia i nā ʻano like ʻole e like me ka makemake o ka mākeke.
ʻO ka graphite crucible i hana ʻia e Hexi carbon he maikaʻi ka thermal conductivity, ke kūpaʻa wela kiʻekiʻe, ka pale ʻana i ka corrosion, ka hoʻonui haʻahaʻa haʻahaʻa haʻahaʻa a me ke kūpaʻa kemika maikaʻi. I ke kaʻina hana, ʻoiai ke kiʻekiʻe loa ka mahana, hiki ke mālama i ka hana maikaʻi; ʻO ka hoʻololi koke ʻana o ke anuanu a me ka wela ka mea liʻiliʻi i ka hana crucible. He hana maikaʻi ʻo Graphite crucible i ka hoʻoheheʻe ʻana i nā mea hoʻoheheʻe, nā metala nonferrous a me nā mea hoʻohui ʻē aʻe, no laila ua hoʻohana nui ʻia i ka metallurgy, ka hoʻolei ʻana, ka mīkini, ka ʻoihana kemika a me nā ʻoihana ʻē aʻe. He hopena maikaʻi ka graphite crucible i hana ʻia e Hexi Carbon Factory ma ka ʻenehana a me ka hoʻohana ʻana. Hiki iā mākou ke hana i nā crucibles graphite me nā diameters mai ka 300 mm a hiki i ka 800 mm, a hiki ke hoʻonohonoho pono iā lākou e like me nā koi o ka mea kūʻai aku. E nānā ʻia ka maikaʻi o nā huahana graphite i hāʻawi ʻia e kā mākou hui ma mua o ka haʻalele ʻana i ka hale hana. Inā he mau pilikia, hoʻohiki mākou e hoʻoponopono iā lākou i loko o 5 mau lā hana.
Hoʻohana i nā electrodes
Ke hoʻohana ʻia ka electrode, pono e hoʻomaloʻo ʻia e ka umu uila ma mua, ʻaʻole pono ka mahana ma mua o 150 ℃ a ʻaʻole pono ka manawa ma lalo o 24 mau hola.
