400 UHP graphite electrode
Hoʻohana nui ʻia nā electrodes graphite i ke kaʻina hana kila. Hoʻoheheʻe ʻia ka ʻōpala hao i loko o ka umu ahi a hana hou ʻia. Ma ke ʻano he conductor, he mea nui lākou i kēia ʻano
ʻO ka UHP graphite electrode ka mea nui i hana ʻia me ka coke needle kiʻekiʻe, a hoʻohana nui ʻia i nā kapuahi uila uila kiʻekiʻe kiʻekiʻe.

Kaʻina hana hana
ʻO ka graphite electrode ka mea nui i hana ʻia me ka coke petroleum a me ka coke needle, i hui pū ʻia me ka pitch lanahu, e hele ana i nā kaʻina hana o ka calcinations, kneading, hoʻokumu ʻana, baking, graphitizing a me ka mīkini, a lilo i huahana. Eia kekahi mau wehewehe no kekahi kaʻina hana.
Kneading: ʻO ka hoʻoulu ʻana a me ka hui ʻana i kekahi nui o nā ʻāpana kalapona a me ka pauka me kahi nui o ka mea hoʻopaʻa i kahi mahana, ua kapa ʻia kēia hana ʻo ka hui ʻana.
ʻO ka hana o ka hui ʻana
①E hoʻohui like i nā ʻano mea maka, a ma ka manawa like e hana i nā mea kalapona paʻa o nā ʻāpana like ʻole e hui like a hoʻopiha, a hoʻomaikaʻi i ka nui o ka hui;
②Ma hope o ka hoʻohui ʻana i ka asphalt lanahu, e hui pū i nā mea a pau.
③Ke komo nei kekahi mau pahu lanahu i loko o nā lua o loko, kahi e hoʻomaikaʻi hou ai i ka nui a me ka pili ʻana o ka paʻi.
Hana ʻia: Hoʻokuʻu ʻia ka paʻi kalapona i kāwili ʻia i loko o ke kino ʻōmaʻomaʻo (a i ʻole ka hua ʻōmaʻomaʻo) me kekahi ʻano, ka nui, ka nui a me ka ikaika i loko o kahi mea hana. Loaʻa i ka pāpaʻi kahi deformation plastic ma lalo o ka ikaika o waho.
ʻO ka hoʻomoʻa ʻana i kapa ʻia ʻo ka kuke ʻana, ʻo ia kahi mālama wela kiʻekiʻe, e hana ana i ka lanahu pitch carbonized i ka coke i hoʻokumu ʻia, ka mea e hoʻohui i nā carbonaceous aggregates a me nā ʻāpana pauka me ka ikaika mechanical kiʻekiʻe, haʻahaʻa resistivity, ʻoi aku ka maikaʻi o ka wela a me ka paʻa kemika.
ʻO ke kālua lua ʻana, ʻo ia ke kālua ʻana i hoʻokahi manawa, e hoʻolilo i ka pitch penetrating carbonized. ʻO nā uila (nā ʻano āpau koe wale nō RP) a me nā nipples e koi ana i ka ʻoi aku ka nui o ka nui e pono e hoʻomoʻa ʻia i ka lua, a me nā nipples ʻekolu-luu ʻehā-bake a ʻelua-luu ʻekolu-bake.
