RP GRAPHITE ECTRODE - Hoʻokele uila maikaʻi, hoʻohana haʻahaʻa
WEHEWEHE
ʻO nā electrodes graphite RP, i kapa ʻia ʻo nā kolamu graphite i hoʻoheheʻe ʻia, hoʻohana ʻia ma ke ʻano he mea alakaʻi wela kiʻekiʻe no nā umu arc uila. Ua kuhikuhi ʻia nā electrodes graphite mana maʻamau me ka density au i ʻae ʻia ma lalo o 17 A/cm2. ʻO ke ʻano o ka electrode graphite e hoʻoholo ai i ka huahana a me ke kumukūʻai o ka hana kila EAF.
Ma ke ʻano he mea hana, hāʻawi pū mākou i nā electrodes graphite UHP a me nā electrodes graphite HP no nā umu arc uila mana kiʻekiʻe loa a i ʻole ka mana kiʻekiʻe. Ma waho aʻe o ka hoʻohana ʻia ʻana i loko o nā umu arc, hoʻohana nui ʻia nā electrodes graphite i loko o nā umu arc i lalo o ka wai a me nā umu Ladle.
HIʻONA
Ka mana lawe au kiʻekiʻe.
Ke kūpaʻa koʻikoʻi i ka haki ʻana.
Ke kūpaʻa kiʻekiʻe i ka oxidation a me ka haʻalulu wela.
ʻO ke kūpaʻa o ka ana maikaʻi, ʻaʻole maʻalahi ke hoʻololi.
Ikaika mechanical kiʻekiʻe, kū'ē uila haʻahaʻa.
ʻO ke pololei o ka mīkini kiʻekiʻe, ka hoʻopau ʻana i ka ʻili maikaʻi.
PALAPALA NOI
Hoʻohana nui ʻia nā electrodes graphite no ka hana ʻana i nā kila metala, nā metala a me nā mea hana ʻē aʻe ʻaʻole metala.
