Ka Hana Hana O ka Graphite Electrode
ʻO ka graphite electrode kahi ʻano mea hana graphite conductive kiʻekiʻe wela i hana ʻia e ka hoʻohana ʻana i ka coke petroleum, coke needle e like me ka aggregate, asphalt lanahu e like me ka mea hoʻopili, ma hope o ke ʻano o nā kaʻina 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 hoʻopili ʻia ka coke peila a i ʻole asphalt coke, a hiki i ka mahana calcination ke piʻi i 1300 ℃, no laila e kauoha e hoʻopau piha i ka ʻikepili volatile 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 calcined a nānā 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 ʻo ka hui maloʻo e hoʻopili ʻia e like me ke ʻano.
(3) Hui.I loko o ka moku'āina hoʻomehana, ua hui pū 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 kekahi ʻano a me ke kiʻekiʻe kiʻekiʻe o ka electrode maka (billet).
(5) Kaʻai ʻana.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 kaomi 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 graphitization, i 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 i 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 hoʻoili 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.
