Noocyada kala duwan ee kaarboonka iyo alaabta korantada graphite, marka loo eego isticmaalkooda kala duwan, waxaa jira shuruudaha isticmaalka gaarka ah iyo tilmaamayaasha tayada.Marka la tixgelinayo nooca alaabta ceeriin ee loo isticmaalo badeecad gaar ah, waa in aan marka hore barano sida loo buuxiyo shuruudahan gaarka ah iyo tilmaamayaasha tayada.
(1) Doorashada alaabta ceeriin ee samaynta graphite electrode loo isticmaalo habka elektiroonigga ah sida birta EAF.
Electrode graphite conductive loo isticmaalo geeddi-socodka electrometallurgical sida EAF steelmaking waa in uu leeyahay conductivity wanaagsan, xoog makaanik ku habboon, caabin wanaagsan deminta iyo kulaylka heerkulka sare, iska caabin daxalka iyo content wasakh hoose.
① Electrodes garaafyada tayada sare leh ayaa laga soo saaraa kookaha batroolka, kookaha garoonka iyo alaabta ceeriin ee kale ee dambaska hooseeya.Si kastaba ha ahaatee, wax soo saarka ee electrode graphite u baahan yahay qalab dheeraad ah, socodka geedi socodka dheer iyo technology adag, iyo isticmaalka korontada ee 1 t graphite electrode waa 6000 ~ 7000 kW · H.
② Anthracite ama kookaha birta ah ee tayada sare leh ayaa loo isticmaalaa sida walxo ceeriin ah si loo soo saaro electrode kaarboon.Wax soo saarka ee electrode carbon uma baahna qalabka graphitization, iyo hababka kale ee wax soo saarka la mid ah sida wax soo saarka ee graphite electrode.Daawashada korantada kaarboonku aad ayuu uga xun yahay kan korantada graphite.Iska caabin ah electrode carbon guud ahaan waa 2-3 jeer ka badan ka graphite electrode.Waxyaabaha ku jira dambaska waxay ku kala duwan yihiin tayada alaabta ceeriin, taas oo ah qiyaastii 10%.Laakiin ka dib nadiifinta gaarka ah, nuxurka dambaska ee anthracite waa la dhimi karaa in ka yar 5%.Waxa ku jira dambaska badeecada waxa lagu dhimi karaa ilaa 1.0% hadii alaabta la sii sawiro.Electrode kaarboon waxaa loo isticmaali karaa dhalaalidda birta EAF ee caadiga ah iyo ferroalloy
③ Isticmaalka garaafyada dabiiciga ah sida walxo ceeriin ah, electrode garaaf dabiici ah ayaa la soo saaray.Garaafyada dabiiciga ah waxaa la isticmaali karaa oo kaliya ka dib marka si taxadar leh loo doorto oo waxa ku jira dambaska la yareeyo.Iska caabbinta elektrodegga garaafyada dabiiciga ah waxay ku saabsan tahay labanlaab ka elektrodega graphitized.Laakin xoogga farsamada waa mid hooseeya, fududahay in la jebiyo marka la isticmaalayo.Aagga leh wax soo saarka garaafyada dabiiciga ah ee badan, korantada garaafyada dabiiciga ah ayaa la soo saari karaa si ay u siiso EAF yar si ay u dhalaaliso birta EAF ee caadiga ah.Markaad isticmaasho garaafyada dabiiciga ah si loo soo saaro korantada korantada, qalabka iyo tignoolajiyada way fududahay in la xalliyo oo la maareeyo.
④ Graphite Electrode waxa loo isticmaalaa in lagu soo saaro electrode dib loo soo nooleeyay (ama graphitized electrode jabay) iyada oo la burburinayo oo la shiidi karo qashinka ama alaabta qashinka.Mawduuca dambaska ee alaabtu maaha mid sarreeya (qiyaastii 1%), iyo korriinteedu way ka sii xun tahay tan elektiroonigga graphitized.Iska caabintiisu waxay ku saabsan tahay 1.5 jeer ka mid ah electrode-ga garaafyada, laakiin saameynteeda codsigu way ka fiican tahay kan elektiroonigga graphite ee dabiiciga ah.Inkasta oo ay fududahay in la aqoonsado tignoolajiyada iyo qalabka si loo soo saaro electrode dib loo soo nooleeyo, ilaha alaabta ceeriin ee garaafyada ayaa xaddidan, markaa habkani maaha jihada horumarinta.
