Hoʻokumu ʻia nā electrodes graphite kiʻekiʻe mai ka coke petroleum kiʻekiʻe (a i ʻole coke needle haʻahaʻa). ʻO ke kaʻina hana e pili ana i ka calcination, batching, kneading, molding, baking, dipping, second baking, graphitization and processing. ʻO ka mea maka o ka nipple i lawe ʻia mai ai ka ʻaila nilala coke, a ʻo ke kaʻina hana e komo ana i ʻelua ʻau ʻana a me ʻekolu bakena. ʻOi aku ka kiʻekiʻe o kona mau kino kino a me ka mechanical ma mua o nā electrodes graphite mana maʻamau, e like me ka resistivity haʻahaʻa a me ke kiʻekiʻe o kēia manawa.
