RP Graphite Electrode don Ladle Furnace
Rarraba na Graphite Electrodes
Electric Arc karfe yin makera za a iya raba na yau da kullum wutar lantarki tanderu (kimanin 300KVA per ton), high-power lantarki tanderu (kimanin 400kVA per ton) da matsananci-high-ikon wutar lantarki (500 ~ 1200KV / A da ton) bisa ga karfin wutan lantarki a kowace ton na ƙarfin wutar lantarki.
Bisa ga rarrabuwa na lantarki matakin lantarki tanderu karfe yin, kuma bisa ga bambance-bambancen da albarkatun kasa amfani da lantarki samar da jiki da kuma sinadaran fihirisa na ƙãre electrode, graphite lantarki da aka raba uku iri: na yau da kullum ikon graphite lantarki (RP). , High Power graphite electrode (HP) da ultra high power graphite electrode (UHP).
Gabatarwar RP Graphite Electrode
RP graphite lantarki akasari an yi shi da coke na man fetur azaman albarkatun ƙasa da kwalta kwalta azaman ɗaure ta hanyar calcination, batching, kneading, gyare-gyare, yin burodi, graphitization da machining.
Graphite Electrode shine madugu wanda ke fitar da makamashin lantarki a cikin tanderun wutar lantarki don zafi da narkar da tarkacen karfe.
Siffofin
RP graphite lantarki da aka samar da man fetur coke, tare da ƙananan graphitization zafin jiki.yana da siffofi kamar haka:
1.High resistivity
2.Large mikakke fadada coefficient
3.Poor thermal girgiza juriya
4.The allowable halin yanzu yawa ne low
Aikace-aikacen RP Graphite Electrode
(1) Don yin ƙarfe a cikin wutar lantarki ta Arc (EAF) da Furnace Ladle (LF)
Ana amfani da lantarki na RP Graphite musamman a cikin LF/EAF don yin ƙarfe.Lokacin da graphite electrode ke aiki a cikin LF, za a gabatar da na yanzu ta hanyar lantarki na graphite a cikin tanderun, kuma za a sami tushen zafi wanda ke haifar da baka na lantarki tsakanin ƙarshen lantarki da cajin tanderun don narkewa.
(2) Don samar da siliki na ƙarfe da phosphorus mai launin rawaya a cikin tanderun da aka nutsar
Ana amfani da wasu na'urorin lantarki masu girma (misali.700mm-1400mm) don samar da siliki na ƙarfe da kuma phosphorus mai launin rawaya a cikin tanderun da aka nutsar.An binne ƙananan ɓangaren carbon electrode a cikin cajin, yana samar da arc a cikin cajin cajin, kayan za a narke da makamashin zafi da aka haifar ta hanyar juriya na cajin.Misali, kimanin kilogiram 100 na graphite electrode ana cinyewa don ton 1 na silicon karfe.
(3)Don samar da corundum a cikin tanderun lantarki
(4)Ana amfani da shi don sarrafa samfuran graphite na musamman
Hakanan ana amfani da blank na graphite electrode don sarrafa nau'ikan samfura masu siffa ta musamman
