Hoʻomaka i nā Electrodes Graphite

ʻO ka graphite electrodehana nui ia me ka petroleum coke a me ka nila coke e like me nā mea maka, hoʻohana ʻia ka lanahu tar pitch ma ke ʻano he mea hoʻopaʻa, a hana ʻia e ka calcination, batching, kneading, kaomi ʻana, ka ʻala, graphitization, a me ka mīkini. Hoʻokuʻu ʻo ia i ka ikehu uila ma ke ʻano o ke arc uila i loko o ka umu ahi uila. Hiki ke hoʻokaʻawale ʻia nā conductors e wela a hoʻoheheʻe i ka uku i nā electrodes graphite mana maʻamau, nā electrodes graphite mana kiʻekiʻe a me nā electrodes graphite mana kiʻekiʻe e like me kā lākou mau hōʻailona maikaʻi.
ʻO ka mea maka nui nographite electrodeʻO ka hana ʻana he petroleum coke. Hiki ke hoʻohui ʻia nā electrodes graphite maʻamau me kahi liʻiliʻi o ka pitch coke, a ʻaʻole hiki ke ʻoi aku ka nui o ka sulfur o ka petroleum coke a me ka pitch coke ma mua o 0.5%. Pono pū ʻia ʻo Needle coke i ka wā e hana ai i nā electrodes graphite mana kiʻekiʻe a i ʻole ultra-high-power. ʻO ka mea kumu nui no ka hana ʻana i ka anode alumini he petroleum coke, a ʻaʻole i ʻoi aku ka nui o ka sulfur ma mua o 1.5% a 2%. Pono ka petroleum coke a me ka pitch coke e kūpono i nā kūlana kūpono o ka ʻāina.
