RP Graphite Electrode no ka Ladle Furnace
Ka Hoʻokaʻawale ʻana o nā Electrodes Graphite
Hiki ke hoʻokaʻawale ʻia ka umu ahi hana hao uila i ka umu uila mana maʻamau (e pili ana i 300KVA no ka ton), ka umu uila mana kiʻekiʻe (e pili ana i 400kVA no ton) a me ka umu uila ultra-high-power (500 ~ 1200KV/A no ton) e like me ka. ka mana transformer no ke tona o ka mana kapuahi.
E like me ka hoʻokaʻawale ʻana o ka pae uila o ka umu uila e hana ana, a e like me nā ʻokoʻa o nā mea maka i hoʻohana ʻia i ka hana electrode a me ke kino a me nā kemika indexes o ka electrode hoʻopau, ua māhele ʻia ka graphite electrode i ʻekolu mau ʻano: ka mana maʻamau graphite electrode (RP) , High Power graphite electrode (HP) a me ultra-high power graphite electrode (UHP).
ʻO ka hoʻomaka ʻana o RP Graphite Electrode
Hana ʻia ʻo RP graphite electrode me ka petroleum coke e like me nā mea maka a me ka asphalt lanahu e like me ka binder ma o ka calcination, batching, kneading, molding, baking, graphitization and machining.
ʻO ka Graphite Electrode kahi mea hoʻoheheʻe e hoʻokuʻu i ka ikehu uila i loko o ka umu ahi e wela a hoʻoheheʻe i ka ʻōpala kila.
Nā hiʻohiʻona
Hoʻokumu ʻia ka electrode graphite RP me ka petroleum coke, me ka haʻahaʻa haʻahaʻa graphitization.Loaʻa iā ia nā hiʻohiʻona penei:
1.High resistivity
2.Large laina hoʻonui hoʻonui
3.Poor pu'e wela wela
4. He haʻahaʻa ka nui o kēia manawa i ʻae ʻia
ʻO ka noi o RP Graphite Electrode
(1) No ka hana kila ma Electric Arc Furnace (EAF) a me Ladle Furnace (LF)
Hoʻohana nui ʻia ʻo RP Graphite electrode ma LF/EAF no ka hana kila.Ke hana nei ka graphite electrode i LF, e hoʻokomo ʻia ke ʻano e ka graphite electrode i loko o ka umu, a aia kahi kumu wela i hana ʻia e ka uila uila ma waena o ka hopena electrode a me ka uku o ka umu no ka hoʻoheheʻe ʻana.
(2) No ka hana ʻana i ka silikona metala a me ka phosphorus melemele i loko o ka umu ahi i hoʻopaʻa ʻia
Hoʻohana ʻia kekahi mau electrode kalapona me ka nui nui (eg.700mm-1400mm) no ka hana ʻana i ka silikoni metala a me ka phosphorus melemele i loko o ka umu ahi arc.ʻO ka ʻāpana haʻahaʻa o ka electrode kalapona i kanu ʻia i loko o ka hoʻopiʻi, hana i kahi arc i ka papa hoʻopiʻi, e hoʻoheheʻe ʻia ka mea e ka ikehu wela i hana ʻia e ke kūʻē ʻana o ka uku.No ka laʻana, ma kahi o 100kg o ka graphite electrode e hoʻopau ʻia no 1 tons o ka silika metala.
(3) No ka hana ʻana i ka corundum i ka umu uila
(4) Hoʻohana ʻia no ka hana ʻana i nā huahana graphite kūikawā
Hoʻohana ʻia ka blank o ka graphite electrode e hana i nā ʻano hana graphite kūikawā kūikawā
Nā Kaʻina Hana Hana o ka Electrode Graphite
