Nā Kūlana Electrode Graphite i ka hana kila
I ka ʻoihana hana kila, ʻo ke kaʻina hana ʻo Electric Arc Furnace (EAF) kekahi o nā ala i hoʻohana nui ʻia. He mea nui ke koho ʻana i ka electrode graphite kūpono no kēia kaʻina hana. ʻO RP (Regular Power) graphite electrodes kahi koho kaulana ma muli o ko lākou kūpono a kūpono hoʻi no ka hana o ka umu ahi.
Ke koho ʻana i nā electrodes graphite RP, aia kekahi mau mea nui e noʻonoʻo ai. ʻO kekahi ke anawaena o ka electrode, pono e kūpono i ka nui o ka umu ahi a me nā koi hana. ʻO ka helu o ka electrode kekahi kumu; Hoʻokaʻawale pinepine ʻia nā electrodes graphite RP i ʻehā mau papa e like me ko lākou pale uila a me ka ikaika flexural. Pono e koho ʻia ka papa kūpono ma muli o nā koi kikoʻī o ka hana o ka umu.
Manaʻo ʻikepili no ka hoʻohālikelike ʻana i ka Electrode Graphite me ka umu ahi Arc uila
