ʻO ka mea maʻamau, ʻo ka busbar ma waena o ka hopena o ka DC graphitization furnace rectifier cabinet a me ka conductive electrode o ke poʻo umu i kapa ʻia he ʻupena pōkole, a ʻo ka busbar i hoʻohana ʻia i ka umu graphitization maʻamau. Hana ʻia ka busbar o ka umu graphitization i ke keleawe a me ka alumini. He kiʻekiʻe ka ikaika mechanical, conductivity uila maikaʻi a me ke kūpaʻa corrosion ikaika. ʻAʻole liʻiliʻi iki ka alumini, akā ʻoi aku ka liʻiliʻi o ka alumini a ʻoi aku ka māmā.
Papa 3-2 Nā ʻikepili hana pili o ke keleawe a me ka aluminika

Ma muli o ka liʻiliʻi o ka pale ahi o ka umu graphitization, ʻoi aku ka nui ma ka pae hope o ka hoʻouna ʻana i ka mana, e liʻiliʻi ke kūpaʻa o ka umu ahi, a ua hoʻonui ʻia ke kaomi o ka ʻupena pōkole, e hoʻonui ai i ka nalowale o ka mana. No laila, inā hiki i ka umu graphitization ke hana me ka palekana a me ka hoʻokele waiwai e pili kokoke ana i nā ʻano o ka ʻupena pōkole.
ʻO ke kumu kumu nui ka hoʻemi ʻana i ka impedance o ka ʻupena pōkole a mālama i ka ʻupena pōkole holoʻokoʻa me kahi hāʻule liʻiliʻi. Aia nā pilina like ʻole i loko o ka mesh pōkole o ka umu graphitization. Inā loaʻa ka pilina ma waena o ka electrode conductive a me ke kaʻa keleawe, ka pilina ma waena o ke kaʻa keleawe keleawe a me ke kaʻa alumini, ka pilina ma waena o ke kaʻa alumini, a me nā mea ʻē aʻe, e hoʻopuka kēia mau pilina i ke kūpaʻa pili, e pili ana i nā ʻano o ka ʻupena pōkole holoʻokoʻa. . ʻAʻole pili wale ke ʻano o ka mea i ke ʻano o ka mea hoʻopili, akā ma ka wahi hoʻopili a me ke kaomi pili i ka manawa o ka pilina pili. No kēia kumu, ʻo ka mea maʻamau i ka wā e hoʻopili ai i nā busbars: paʻa ka polishing.
