1. Hana ʻia mai nā mea graphite kiʻekiʻe, ua kūkulu ʻia kā mākou mau electrodes graphite diameter liʻiliʻi e kū i nā wela wela a hāʻawi i ka conductivity uila maikaʻi loa.Mālama kēia i kahi kaʻina hana hoʻoheheʻe paʻa a maikaʻi, e hopena i ka maikaʻi o ka huahana a me ka hoʻemi ʻana i ka ikehu.
2. ʻO ka liʻiliʻi liʻiliʻi o kēia mau electrodes e hiki ai ke hoʻomalu pono i ke kaʻina hana hoʻoheheʻe ʻana, e hoʻomaʻamaʻa iā lākou no nā noi e koi ana i ka pololei kiʻekiʻe a me nā hopena maikaʻi.Inā ʻoe e hana ana i nā mea hao a i ʻole ka hoʻomaʻemaʻe ʻana i nā metala, e kōkua kā mākou electrodes iā ʻoe e hoʻokō i ka hopena i makemake ʻia me ka pololei ʻole.
3. ʻO kā mākou mau electrodes graphite liʻiliʻi liʻiliʻi e kūpono i ka nui o nā ʻoihana, e like me ka hana kila, ka hana kemika, a me ka hoʻolei ʻana i ka metala.No ka nui o kāu hana, hiki ke hoʻonohonoho ʻia kā mākou electrodes e hoʻokō i kāu mau koi kikoʻī.
4. Ma ka hana kila, hoʻohana ʻia kā mākou mau electrodes graphite liʻiliʻi i loko o nā kapuahi uila, kahi e hana nui ai lākou i ka hana ʻana i ke kila kiʻekiʻe.ʻO ko lākou liʻiliʻi liʻiliʻi e hiki ai ke hoʻomalu pono i ke kaʻina hoʻoheheʻe, e hōʻoia i nā hopena kūlike a me ka hoʻemi ʻana i ka ʻōpala.
5. I ka hana kemika, pono kā mākou mau electrodes no ka hana ʻana i ka calcium carbide a me ka hoʻomaʻemaʻe ʻana o ka carborundum.Pono kēia mau kaʻina hana i ka mālama ʻana i ka wela, kahi e hāʻawi ai kā mākou electrodes me ka pololei loa.
6. No ka hoʻoheheʻe ʻia ʻana o ka metala, hoʻohana ʻia kā mākou mau electrodes graphite liʻiliʻi i ka hoʻoheheʻe ʻana i nā metala liʻiliʻi a me nā mea kanu Ferrosilicon.ʻO ka conductivity maikaʻi o ka graphite e hiki ai i ka hoʻoheheʻe maikaʻi ʻana o nā metala, ka hopena i ka wikiwiki o ka hana ʻana a me ka nui o ka huahana holoʻokoʻa.
