Ka Hana Hana O ka Graphite Electrode
ʻO ka graphite electrode kahi ʻano o ka graphite conductive mea wela kiʻekiʻe i hana ʻia e ka hoʻohana ʻana i ka coke petroleum, coke needle e like me ka aggregate, asphalt asphalt e like me ka binder, ma hope o ke ʻano o nā kaʻina hana e like me ka hui ʻana, ka hoʻoheheʻe ʻana, ka ʻulaʻula, ke kuʻi ʻana, ka graphitization a me ka hana mechanical.
ʻO nā kaʻina hana nui o ka electrode graphite penei:
(1) Calcination. Pono e hana ʻia ka coke a me ka asphalt coke, a ʻo ka mahana calcination e hiki i 1300 ℃, no laila e kauoha e hoʻopau piha i ka maʻi maʻi i loko o nā mea kalapona, a hoʻomaikaʻi i ka ʻoiaʻiʻo, ka ikaika mechanical a me ka conductivity uila o ka coke.
(2) ka ʻohi ʻana, ka nānā ʻana, a me nā mea ʻai. Ua haki ʻia nā mea kalapona kalapona i kālai ʻia a hoʻopaʻa ʻia i loko o nā ʻāpana aggregate o ka nui i ʻōlelo ʻia, ʻāpana ʻia ka ʻāpana o ka coke i loko o ka pauka maikaʻi, a hoʻopili ʻia ka hui maloʻo e like me ke ʻano.
(3) Hui. I ka mokuʻāina hoʻomehana, ua hui ʻia ka hui maloʻo nui o nā ʻāpana like ʻole me ka binder quantitative, hui ʻia a kāwili ʻia e synthesize i ka paʻi plastik.
(4) hoʻoheheʻe ʻia, ma lalo o ka hana o ke kaomi o waho (extrusion forming) a i ʻole ma lalo o ka hana o ka haʻalulu kiʻekiʻe (vibration forming) e kaomi i ka paʻi i loko o kekahi ʻano a me ke kiʻekiʻe kiʻekiʻe o ka electrode maka (billet).
(5) Baking. Hoʻokomo ʻia ka electrode maka i loko o kahi umu hoʻoheheʻe kūikawā, a hoʻopiha ʻia ka pauka coke metallurgical a uhi ʻia me ka electrode maka. Ma ka wela kiʻekiʻe o ka mea hoʻopaʻa paʻa ma kahi o 1250 ℃, hana ʻia ka electrode carbon roasting.
(6) Immaculate. I mea e hoʻomaikaʻi ai i ka nui a me ka ikaika mechanical o nā huahana electrode, hoʻokomo ʻia ka electrode roasting i loko o nā mea uila kiʻekiʻe, a hoʻokomo ʻia ka asphalt wai wai i loko o ka lua ea o ka electrode. Ma hope o ka hoʻopaʻa ʻia ʻana, pono e hana ʻia ke kālua ʻana i hoʻokahi manawa. E like me nā koi o ka hana o ka huahana, i kekahi manawa pono e hana hou ʻia ka impregnation a me ka lua ʻana i 23 mau manawa.
(7) graphitization. Hoʻokomo ʻia ka electrode kalapona i hoʻomoʻa ʻia i loko o ka umu ahi graphitization, uhi ʻia me ka mea insulation. Ma ka hoʻohana ʻana i ke ʻano hoʻomehana o ka electrification pololei e hana i ka wela kiʻekiʻe, ua hoʻololi ʻia ka electrode kalapona i electrode graphite me ka hoʻolālā aniani graphite ma ke kiʻekiʻe o 2200 ~ 3000 ℃.
(8) mīkini. E like me nā koi hoʻohana, ka huli ʻana o ka graphite electrode blank surface, flat end surface a me nā puka wili no ka hoʻopili pili ʻana, a me ka hui no ka pilina.
(9) E hoʻopili pono ʻia ka electrode graphite ma hope o ka hala ʻana o ka nānā ʻana a hoʻouna ʻia i ka mea hoʻohana.
