400 UHP graphite electrode
graphite electrodes e masani ona faʻaaogaina i le faʻagasologa o le uʻamea. E liusuavai fasi u'amea i totonu o le ogaumu arc eletise ma toe fa'aaogaina. I le avea ai o se ituaiga taʻavale, o latou o se vaega taua i lenei ituaiga
UHP graphite electrode e masani lava ona faia i luga o le nila sili coke sili, ma faʻaaogaina lautele i ultra high power arc arc furnaces. E mafai ona tauaveina le mamafa o loʻo iai nei e sili atu i le 25A / cm2

Fa'agasologa o le gaosiga
Graphite electrode e masani lava ona faia i le suauʻu coke ma nila coke, fefiloi ma le koale pitch, e ala i faagasologa o calcinations, lomi, faia, taoina, graphitizing ma machining, mulimuli ane avea ma oloa. O nisi nei o faʻamatalaga mo nisi faʻagasologa o gaosiga:
Kneading: O le faʻaosoina ma le faʻafefiloi o se aofaʻi o vaega o le kaponi ma le paʻu ma se aofaʻi o mea faʻapipiʻi i se vevela, o lenei faiga e taʻua o le komi.
Ole galuega ole lomi
①Faafefiloi ituaiga uma o mea mataʻina ia tutusa, ma i le taimi lava e tasi ia faia mea kaponi malosi o le tele o vaega laiti e faʻafefiloi tutusa ma faʻatumu, ma faʻaleleia le mamafa o le paluga;
②A mae'a ona fa'apipi'i le koale, fa'apipi'i fa'atasi mea uma.
③O nisi o koale e ulu i totonu o le gaogao i totonu, lea e faʻaleleia atili ai le mamafa ma le pipii o le paʻu.
Fausia: O le pa'u kaponi lomi e fa'aulu i totonu o se tino lanu meamata (po'o se mea lanu meamata) fa'atasi ai ma se foliga patino, lapo'a, mamafa ma le malosi i totonu o se mea fa'apipi'i. O le paʻu o loʻo i ai se paʻu palasitika i lalo o le malosi i fafo.
Roasting taʻua foi tao tao, O se togafitiga vevela maualuga, faia le koale pitch carbonized i coke fausia, lea consolidated le carbonaceous aggregates ma vaega pauta faatasi ma le malosi faainisinia maualuga, resistivity maualalo, mautu lelei vevela ma mautu vailaau.
O le taoina lona lua o le toe tao tasi lea, ma fa'a carbonized le pitch tu'u. Electrodes (ituaiga uma sei vagana ai RP) ma nipples e manaʻomia le maualuga o le mamafa tele e manaʻomia ona faʻalua-lua, ma nipples tolu-fu-fa- tao poʻo lua-fa-tolu- tao.
