ʻIkepili o ke kūlana o kēia manawa o ka ʻoihana Needle Coke!

1. Nā kahua hoʻohana ʻana i nā kīʻaha ʻanode pākahi:

I kēia manawa, ʻo nā mea anode i kūʻai ʻia he graphite maoli a me ka graphite artificial. He mea maʻalahi ke kiʻi kiʻi ʻia ʻo Needle coke a he ʻano mea kiʻekiʻe kiʻekiʻe. Ma hope o ka graphitization, ʻike ʻia ke ʻano fibrous a me ke ʻano microcrystalline graphite maikaʻi. Ma ke kuhikuhi o ke axis lōʻihi o nā ʻāpana, loaʻa iā ia nā mea maikaʻi o ka uila maikaʻi a me ka hoʻoheheʻe wela a me ka liʻiliʻi hoʻonui hoʻonui wela. ʻO Needle coke i ʻoki ʻia, hoʻokaʻawale ʻia, hoʻohālikelike ʻia, granulated, a graphitized no ka loaʻa ʻana o nā mea graphite artificial, kahi kiʻekiʻe kiʻekiʻe o ka crystallinity a me ka graphitization, a kokoke i kahi ʻano graphite layered kūpono.

Ua ulu wikiwiki ka ʻoihana kaʻa ikehu hou i nā makahiki i hala iho nei. Mai Ianuali a Sepatemaba 2022, ʻo 372GWh ka hoʻonui ʻana o nā pā uila mana ma koʻu ʻāina, he 176% ka piʻi ʻana o kēlā me kēia makahiki. Ua wānana ka China Automobile Association e piʻi ka nui o ke kūʻai aku o nā kaʻa uila i 5.5 miliona ma 2022, a ʻo ka helu komo ʻana o nā kaʻa uila i loko o ka makahiki e ʻoi aku ma mua o 5.5 miliona. 20%. Hoʻololi ʻia e ka "laina ʻulaʻula o ka banning combustion" a me ke kulekele kūloko o nā "pahu kalapona ʻelua", ke manaʻo ʻia ka noi honua no nā pā lithium e hiki i 3,008GWh i 2025, a ʻo ke koi no ka coke needle e hiki i ka 4,04 miliona tons.

 

2. Nā kahua noi graphite electrode:

ʻO Needle coke kahi mea waiwai kiʻekiʻe no ka hana ʻana i nā electrodes graphite mana kiʻekiʻe / ultra-kiʻekiʻe. ʻO kona hiʻohiʻona he ʻano hoʻolālā fibrous i hoʻomohala maikaʻi ʻia a me kahi ʻāpana nui o ka lōʻihi-ākea. I ka wā hoʻoheheʻe extrusion, ua hoʻonohonoho ʻia ka axis lōʻihi o ka hapa nui o nā ʻāpana ma ka ʻaoʻao extrusion. . ʻO ka hoʻohana ʻana i ka coke needle e hana i nā electrodes graphite kiʻekiʻe / kiʻekiʻe kiʻekiʻe ka maikaʻi o ka resistivity haʻahaʻa, haʻahaʻa haʻahaʻa haʻahaʻa hoʻonui hoʻonui, ikaika ikaika haʻalulu haʻalulu, haʻahaʻa electrode hoʻohana a kiʻekiʻe i ʻae ʻia i kēia manawa. Loaʻa i nā cokes nila ma ka lanahu a me ka aila ko lākou mau hiʻohiʻona ponoʻī i ka hana. Ma ka hoʻohālikelike o ka pono coke hana, ma ka hoʻohui i ka maoli density, tap density, pauka resistivity, lehu maʻiʻo, sulfur maʻiʻo, nitrogen maʻiʻo, Ma waho aʻeo ka hoohalike ana o ka hana maʻamau nā mea hōʻike e like me ka hiʻona lākiō a me ka particle nui puʻunaue, e nānā pono i ka thermal expansion coefficient, resistivity, compressive ikaika, bulk density, maoli density, bulk expansion, anisotropy a me ka hoʻonui ʻana i ka ʻikepili e like me ka hoʻonui ʻana i ka ʻikepili e like me ka hoʻonui ʻana i ka ʻikepili a me ka ʻike e like me ka hoʻonui ʻana i ka ʻikepili. ʻO ke kūlana i kāohiʻia, ka wela wela i ka wā e hoʻonui ai a me ka hoʻohaʻahaʻaʻana, a me nā mea'ē aʻe. Ma ka holoʻokoʻa, ʻoi aku ka kiʻekiʻe o ka hana ʻana o ka coke nilala aila ma mua o ka coke kola.

ʻO nā ʻoihana kalapona ʻē aʻe e koho pinepine i ka coke ʻaila aila kiʻekiʻe ma ke ʻano he kumu nui no ka hana ʻana i nā electrodes UHP a me HP graphite nui. Ke hoʻohana pū nei nā ʻoihana kalapona Iapana i kekahi coke nilala ma ke ʻano he kumu waiwai, akā no ka hana ʻana i nā electrodes graphite me nā kikoʻī ma lalo o Φ600mm. ʻOiai ʻo ka hana ʻoihana o ka coke needle ma koʻu ʻāina ma mua o nā hui ʻē aʻe, ua ulu wikiwiki ia i nā makahiki i hala iho nei a ua hoʻomaka i ke ʻano. I kēia manawa, ʻo koʻu ʻāina ka mana kiʻekiʻe o ka graphite electrode aggregates, ʻo ia ka nui o ka coke kola. Ma ke ʻano o ka hana holoʻokoʻa, hiki i nā ʻāpana hana coke kūloko ke hoʻokō pono i nā pono o nā ʻoihana kalapona e hana i nā electrodes graphite kiʻekiʻe / ultra-power no ka coke needle. Eia nō naʻe, aia kekahi ʻokoʻa i hoʻohālikelike ʻia me nā hui haole i ka maikaʻi o ka coke needle. Ke hilinaʻi nei ka nui-nui ultra-kiʻekiʻe-mana graphite electrode maka i ka nila i lawe ʻia mai, ʻoi aku ka kiʻekiʻe / ultra-mana graphite electrode ami ʻia. Needle coke e like me ka mea maka.

I ka makahiki 2021, he 1.037 biliona tons ka hana ʻana o ke kila kila, a ʻo ia ka mea i emi iho ma lalo o 10%. Hoʻolālā pū ke Keʻena ʻOihana a me ka ʻIke ʻIke ʻenehana e hoʻonui i ka nui o ka umu uila i ʻoi aku ma mua o 15% ma 2025. Ua wānana ka National Iron and Steel Association e hiki i 30% i 2050. E hōʻea i ka 60% i 2060. ʻO ka hoʻonui ʻana i ka lākiō steelmaking o nā kapuahi uila e hoʻokele pololei i ke koi, no ka mea, e hoʻokele pono i ka pono no nā uila uila.
