He mea koʻikoʻi koʻikoʻi ka graphite electrode no ka hana ʻana i ka umu uila. Hoʻokomo ʻia ka ikehu uila i loko o ka umu uila ma o ka graphite electrode, a ʻo ka wela kiʻekiʻe i hana ʻia e ke arc ma waena o ka hopena electrode a me ka uku hoʻohana ʻia i kumu wela e hoʻoheheʻe i ka uku no ka hana kila. Aia nā kikoʻī mai 300 a 800mm ka anawaena a me 1.8m, 2.1m, 2.4m, a me 2.7m ka lōʻihi.

ʻO ke kaʻina hana ʻo ka calcine petroleum coke ma 1350 ° C. ʻO ka hopena o ka coke calcined e ʻoki ʻia, lepo a hoʻopaʻa ʻia e hana i ka aggregate a me ka pauka e pono ai no ka hoʻoheheʻe ʻana. Hoʻopili ʻia ka coke a me ka pauka me ka hoʻohana ʻana i kahi ʻano loea kūikawā no ka hoʻoheheʻe ʻana. Hoʻohui ʻia ka coke calcined me nā ʻāpana like ʻole, nā ʻāpana like ʻole a me kahi ʻāpana o ka asphalt binder i loko o ka kneader e like me kahi mahana a me ka manawa.

Ma hope o ka kāwili ʻana, hoʻouna ʻia ka paʻi kalapona i ke keʻena waiwai o ka mīkini paʻi ma o ke kāʻei conveyor, a hoʻohana ʻia e nā mea hana. Hana ʻia ka hoʻololi ʻana o ka plastik ma lalo o ka ikaika o waho, e hana ana i kahi kino ʻōmaʻomaʻo electrode (a i ʻole huahana ʻōmaʻomaʻo) me kekahi ʻano, ka nui, ka nui a me ka ikaika. Hoʻokomo ʻia ka huahana ʻōmaʻomaʻo i loko o kahi umu wela i hoʻolālā ʻia no ka mālama ʻana i ka wela wela ma 1300 ° C e carbonize i ka pitch lanahu i loko o ke kino ʻōmaʻomaʻo e hana i kahi huahana me ka ikaika mechanical kiʻekiʻe, haʻahaʻa resistivity, ʻoi aku ka maikaʻi o ka wela a me ka paʻa kemika.

No nā huahana kalapona, ʻo ka ʻala ʻana kekahi o nā hana nui i ka hana ʻana i nā huahana kalapona. He lōʻihi ka pōʻaiapuni o ka hana ʻana (22-30 mau lā no ka ʻohi mua ʻana, 5-20 mau lā no ka lua ʻana i ka lua ma muli o ke ʻano o ka umu), a ʻoi aku ka nui o ka ikehu. Ma hope o kēlā, hoʻokomo ʻia ka mea kalapona i loko o kahi kīʻaha paʻi, a hoʻokomo ʻia ka asphalt wai impregnating agent a komo i loko o nā pores electrode o ka huahana ma lalo o nā kūlana o 360-400 ° C a me 1.5-1.8MPa kaomi e hoʻonui i ka nui o ka nui. a me ka ikaika mechanical o ka huahana, a hoʻomaikaʻi i ka conductivity a me ka conductivity o ka huahana. ʻO ke kau wela wela.

Ma hope o ka hoʻokomo ʻia ʻana o ka huahana i kālua ʻia, hoʻomoʻi hou ʻia e carbonize i ka pitch i hoʻokomo ʻia i loko o nā pores o ka huahana i kālua ʻia. A laila e hoʻohui i kahi mea pale i ka huahana i kālua ʻia i loko o ka umu uila wela wela e wela ai ka huahana kalapona ma luna o 2800 ° C, e hoʻohuli ana i ke kalapona turbostratic amorphous i loko o kahi hoʻolālā aniani graphite kauoha ʻekolu e hoʻomaikaʻi i ka conductivity uila, thermal conductivity, a me ka wela o ka mea kalapona. ʻO ka hana vibration a me ka paʻa kemika e hana i ka lubricity mea kalapona a me ka anti-wear, a hoʻokuʻu i nā haumia e hoʻomaikaʻi i ka maʻemaʻe o ka mea kalapona. ʻO ka mea hope loa, ke hilinaʻi nei mākou i ka ʻoki ʻana i ka hana e hoʻokō i ka nui e pono ai, ke ʻano, ka pololei, a me nā mea ʻē aʻe, a hana i ke kino electrode e hoʻokō i nā koi hoʻohana.
No ka mea e pono ai nā hui electrode i ke kino kiʻekiʻe a me ka haʻahaʻa haʻahaʻa, pono ke kaʻina hana i ʻekolu dips a me nā kī ʻehā e hoʻokō i nā koi.
Hoʻokō nā huahana o kā mākou hui i nā kūlana YB / T4088-2015, YB / T4089-2015, YB / T4090-2015. ʻO nā electrodes graphite a me nā hono i hana ʻia he kiʻekiʻe ka nui o ka leo, ka ikaika flexural kiʻekiʻe, ka resistivity haʻahaʻa, ke kūpaʻa haʻalulu wela maikaʻi, a he mau waiwai oxidizing ikaika a ʻoi aku ka maikaʻi ma mua o nā kūlana aupuni a me nā ʻoihana. Ua hala ka huahana i ka nānā ʻana o ka National Graphite Product Quality Supervision and Inspection Center.
