1. Hōʻike huahana:

ʻO ka semi-graphitized petroleum coke ka huahana o ka coke petroleum calcined e like me ka mea maka, i waiho ʻia i loko o ka umu graphitizing, ma hope o ka graphitization kiʻekiʻe, ka hopena kino a me ke kemika a me ka wehe ʻana i ka sulfur a me ka lehu a me nā mea haumia ʻē aʻe.I kekahi manawa i kapa ʻia ʻo graphite artificial, hoʻohana ʻia i loko o ka carburizing agent, i ʻike pinepine ʻia he ultra low sulfur/low carburizing agent.

He aila ʻaila paʻa paʻa a ʻeleʻele paha me ka ʻulaʻula metala a me ka porosity, i loko o nā kristal graphite microscopic e hana ana i nā kino kalapona granular, columnar, a i ʻole ka nila-like.ʻO ka Petroleum coke he hydrocarbon, aia ma mua o 99% kalapona, akā aia pū kekahi me ka nitrogen, chlorine, sulfur a me nā pūhui metala kaumaha.

2. Ke ʻano a me ka hoʻohana ʻana:

Hoʻohana nui ʻia ka semi-graphitized petroleum coke i ka ʻoihana.Hoʻohana ʻia ia i ka metallurgy, ka hoʻolei ʻana a me ka hoʻolei pololei ʻana ma ke ʻano he carburizing agent.Hoʻohana ʻia ia e hana i ka crucible wela kiʻekiʻe no ka hoʻoheheʻe ʻana, lubricant no ka ʻoihana mechanical, hana i ka electrode a me ke alakaʻi penikala;Hoʻohana nui ʻia ia i nā mea refractory kiʻekiʻe a me nā uhi i loko o ka ʻoihana metallurgical, pūʻali koa ʻoihana ahi mea stabilizer, penikala alakaʻi i ka ʻoihana māmā, kalapona kalapona i ka ʻoihana uila, electrode i ka ʻoihana pākaukau, catalyst i ka ʻoihana mea kanu kemika, etc. Graphitized petroleum coke hoʻohana ʻia i ka graphite, hoʻoheheʻe a me ka ʻoihana kemika e like me kona ʻano.ʻO ka sulfur haʻahaʻa, kiʻekiʻe kiʻekiʻe i kuke ʻia e like me ka nila coke, hoʻohana nui ʻia i ka hana ʻana i nā electrodes graphite ultra-kiʻekiʻe a me kekahi mau huahana kalapona kūikawā;He mea koʻikoʻi ka Needle coke no ka hoʻomohala ʻana i ka ʻenehana hou o ka hana ʻana i ka umu uila i ka ʻoihana hana kila.ʻO ka sulfur liʻiliʻi, ka coke i kuke ʻia, hoʻohana ʻia i ka hoʻoheheʻe alumini.Hoʻohana ʻia ka sulfur kiʻekiʻe, ka coke maʻamau, no ka hana kemika, e like me ka hana ʻana i ka calcium carbide, silicon carbide, a me nā mea ʻē aʻe, akā he wahie hoʻolei metala.ʻO ka hapa nui o ka coke petroleum i hana ʻia ma Kina he coke sulfur haʻahaʻa, i hoʻohana ʻia e hana i ka alumini a me ka graphite.

ʻO ka graphite electrode ka mea nui i hana ʻia me ka coke petroleum kiʻekiʻe, ʻo ka nila coke e like me ka mea maka, ka asphalt asphalt e like me ka binder, ma ka calcination, batching, kneading, kaomi ʻana, ka ʻai, graptitization, machining a hana ʻia, aia i loko o ka umu ahi i ke ʻano o ka ikehu uila. E hoʻokuʻu i ka ikehu uila i ka umu ahi no ka hoʻomehana a me ka hoʻoheheʻe ʻana i ka conductor, e like me kona ʻano ʻano maikaʻi, hiki ke hoʻokaʻawale ʻia i ka mana maʻamau, ka mana kiʻekiʻe a me ka mana kiʻekiʻe.
